Open source development – how we are doing

- May 29, 2012 in BibServer, JISC OpenBib, jiscopenbib2, licensing, progress, progressPosts, projectMethodology, projectPlan, riskAnalysis, software, WIN, wp10, wp2, wp3, wp6, wp9

Whilst at Open Source Junction earlier this year, I talked to Sander van der Waal and Rowan Wilson about the problems of doing open source development. Sander and Rowan work at OSS watch, and their aim is to make sure that open source software development delivers its potential to UK HEI and research; so, I thought it would be good to get their feedback on how our project is doing, and if there is anything we are getting wrong or could improve on. It struck me that as other JISC projects such as ours are required to make their output similarly publicly available, this discussion may be of benefit to others; after all, not everyone knows what open source software is, let alone the complexities that can arise from trying to create such software. Whilst we cannot help avoid all such complexities, we can at least detail what we have found helpful to date, and how OSS Watch view our efforts. I provided Sander and Rowan a review of our project, and Rowan provided some feedback confirming that overall we are doing a good job, although we lack a listing of the other open source software our project relies on, and their licenses. Whilst such data can be discerned from the dependencies of the project, this is not clear enough; I will add a written list of dependencies to the README. The response we received is provided below, followed by the overview I initially provided, which gives a brief overview of how we managed our open source development efforts: ==== Rowan Wilson, OSS Watch, responds: Your work on this project is extremely impressive. You have the systems in place that we recommend for open development and creation of community around software, and you are using them. As an outsider I am able to quickly see that your project is active and the mailing list and roadmap present information about ways in which I could participate. One thing I could not find, although this may be my fault, is a list of third party software within the distribution. This may well be because there is none, but it’s something I would generally be keen to see for the purposes of auditing licence compatibility. Overall though I commend you on how tangible and visible the development work on this project is, and on the focus on user-base expansion that is evident on the mailing list. ==== Mark MacGillivray wrote: Background – May 2011, OKF / AIM bibserver project Open Knowledge Foundation contracted with American Institute of Mathematics under the direction of Jim Pitman in the dept. of Maths and Stats at UC Berkeley. The purpose of the project was to create an open source software repository named BibServer, and to develop a software tool that could be deployed by anyone requiring an easy way to put and share bibliographic records online. A repository was created at http://github.com/okfn/bibserver, and it performs the usual logging of commits and other activities expected of a modern DVCS system. This work was completed in September 2011, and the repository has been available since the start of that project with a GNU Affero GPL v3 licence attached. October 2011 – JISC Open Biblio 2 project The JISC Open BIblio 2 project chose to build on the open source software tool named BibServer. As there was no support from AIM for maintaining the BibServer repository, the project took on maintenance of the repository and all further development work, with no change to previous licence conditions. We made this choice as we perceive open source licensing as a benefit rather than a threat; it fit very well with the requirements of JISC and with the desires of the developers involved in the project. At worst, an owner may change the licence attached to some software, but even in such a situation we could continue our work by forking from the last available open source version (presuming that licence conditions cannot be altered retrospectively). The code continues to display the licence under which it is available, and remains publicly downloadable at http://github.com/okfn/bibserver. Should this hosting resource become publicly unavailable, an alternative public host would be sought. Development work and discussion has been managed publicly, via a combination of the project website at http://openbiblio.net/p/jiscopenbib2, the issue tracker at http://github.com/okfn/bibserver/issues, a project wiki at http://wiki.okfn.org/Projects/openbibliography, and via a mailing list at openbiblio-dev@lists.okfn.org February 2012 – JISC Open Biblio 2 offers bibsoup.net beta service In February the JISC Open Biblio 2 project announced a beta service available online for free public use at http://bibsoup.net. The website runs an instance of BibServer, and highlights that the code is open source and available (linking to the repository) to anyone who wishes to use it. Current status We believe that we have made sensible decisions in choosing open source software for our project, and have made all efforts to promote the fact that the code is freely and publicly available. We have found the open source development paradigm to be highly beneficial – it has enabled us to publicly share all the work we have done on the project, increasing engagement with potential users and also with collaborators; we have also been able to take advantage of other open source software during the project, incorporating it into our work to enable faster development and improved outcomes. We continue to develop code for the benefit of people wishing to publicly put and share their bibliographies online, and all our outputs will continue to be publicly available beyond the end of the current project.

BibServer new functionality

- March 19, 2012 in announcement, JISC OpenBib, jiscopenbib2, progressPosts, software, wp6, wp7, wp8

During the sprint last week we made a lot of progress with the new functionality for version 0.5.0 – however, Etienne and I got so excited by some new ideas that we did not finish on time; apologies for the delay. We will be making the new version available over the course of this week, and will have it up and running on http://bibsoup.net soon. Below is an overview of the new functionality you can expect to see over the course of the next week; we will write some blog posts about the various new capabilities, and this will tie in with the focus of the next sprint – doing docs, tests and issues (no new functionality).
  • editing of records and collections
  • merging collections from multiple sources
  • adding notes to records
  • much improved search UI
  • embed images in search results
  • better visualisation of collections
  • embeddable UI into other web pages via javascript
  • asynchronous parsing – you don’t have to hang on the page waiting for it to complete
  • feedback tickets from asynchronous parses
  • sharing collection admin rights with other users
  • new parser for NLM XML
  • new parser concept – search term gets pages from wikipedia, pulls citations from pages
  • capability to accept and run parsers written in different programming languages
  • browse site users

Collections in Bibliographica: unsorted information is not information

- June 12, 2011 in inf11, jisc, JISC OpenBib, jiscEXPO, jiscopenbib, News, OKFN Openbiblio, progressPosts, Semantic Web, WIN

Collections are the first feature aimed for our users participation at Bibliographica. The collections are lists of books users can create and share with others, and they are one of the basic features of Bibliographica as Jonathan Gray pointed out already:
lists of publications are an absolutely critical part of scholarship. They articulate the contours of a body of knowledge, and define the scope and focus of scholarly enquiry in a given domain. Furthermore such lists are always changing.
Details of use They are accessible via the collections link on the top menu of the website. To create collections you must be logged in. You may login on http://bibliographica.org/account/login with an openID Once logged in, every time you open a book page (i.e. http://bnb.bibliographica.org/entry/GB6502067 ) you will see at your right the Collections menu, where you can choose between creating a new collection with that work, or adding the work to an already existing collection. If you have created some collections you can always access them through the menu and they are also going to appear in your account page For removing a book from one collection, you can click remove in the collection listing of the sidebar.

Bibliographica gadget in Wikipedia

- June 6, 2011 in Bibliographic, inf11, jisc, JISC OpenBib, jiscEXPO, jiscLMS, jiscopenbib, News, OKFN Openbiblio, progress, progressPosts, Semantic Web, software

What is a wikipedia gadget? Thinking of ways to show the possibilities of linked data, we have made a Wikipedia gadget, making use of a great resource the Wikimedia developers give to the community. Wikipedia gadgets are small pieces of code you can add to your Wikipedia user templates, and allow you to add more functionality and render more information when you browse wikipedia pages. In our case, we wanted to retrieve information from our bibliographica site to render in Wikipedia, and so as the pages are rendered with specific markup we can use the ISBN numbers present on the wikipedia articles to make consults to the bibliographica database, in a way similar to what Mark has done with the Edinburgh International Science Festival. Bibliographica.org offers an isbn search endpoint at http://bibliographica.org/isbn/, so if we ask for the page http://bibliographica.org/isbn/0241105161 we receive [{"issued": "1981-01-01T00:00:00Z", "publisher": {"name": "Hamilton"}, "uri": "http://bnb.bibliographica.org/entry/GB8102507", "contributors": [{"name": "Boyd, William, 1952-"}], "title": "A good man in Africa"}] I can use this information to make a window pop up with more information about works when we hover their ISBNs on the Wikipedia pages. If my user templates has the bibliographica gadget, every time I open a wiki page the script will ask information about all the ISBNs the page has to our database. If something is found, it will render a frame around the ISBN numbers: And if I hover over them, I see a window with information about the book: Get the widget So, if you want to have this widget, first you need to create an account in the wikipedia, and then change your default template to add the JavaScript snippet. Once you do this (instructions here ) you will be able to get the information available in bibliographica about the books. Next steps By now, the interaction goes in just one direction. Later on, we will be able to feed that information back to Bibliographica.

Medline dataset

- May 23, 2011 in announcement, Bibliographic, communityBenefits, Data, inf11, institutionalBenefits, jisc, JISC OpenBib, jiscEXPO, jiscopenbib, News, OKFN Openbiblio, progress, progressPosts, Semantic Web, WIN

Announcing the CC0 Medline dataset

We are happy to report that we now have a full, clean public domain (CC0) version of the Medline dataset available for use by the community.

What is the Medline dataset?

The Medline dataset is a subset of bibliographic metadata covering approximately 98% of all PubMed publications. The dataset comes as a package of approximately 653 XML files, chronologically listing records in terms of the date the record was created. There are approximately 19 million publication records. Medline is a maintained dataset, and updates chronologically append to the current dataset. Read our explanation of the different PubMed datasets for further information.

Where to get it

The raw dataset can be downloaded from CKAN : http://ckan.net/package/medline

What is in a record

Most records contain useful non-copyrightable bibliographic metadata such as author, title, journal, PubMed record ID. Many also have DOIs. We have stripped out any potentially copyrightable material such as abstracts. Read our technical description of a record for further information.

Sample usage

We have made an online visualisation of a sample of the Medline dataset – however the visualisation relies on WebGL which is not yet widely supported by all browsers. It should work in Chrome and probably FireFox4. This is just one example, but shows what great things we can build and learn from when we have open access to the necessary data to do so.

OpenBiblio workshop report

  • Adrian Pohl (OKF bibliographic working group) (remote)
During the workshop we covered some key areas where we have seen some success already in the project, and discussed how we could continue further.

Open bibliographic data formats

In order to ensure successful sharing of bibliographic data, we require agreement on a suitable yet simple format via which to disseminate records. Whilst representing linked data is valuable, it also adds complexity; however, simplicity is key for ensuring uptake and for enabling easy front end system development. Whilst data is available as RDF/XML, JSON is now a very popular format for data transfer, particularly where front end systems are concerned. We considered various JSON linked data formats, and have implemented two for further evaluation. In order to make sure this development work is as widely applicable as possible, we wrote parsers and serialisers for JSON-LD and RDF/JSON as plugins for the popular RDFlib. The RDF/JSON format is, of course, RDF; therefore, it requires no further change to enable it to handle our data, and our RDF/JSON parser and serialiser are already complete. However, it is not very JSON-like, as data takes the subject(predicate(object)) form rather than the general key:value form. This is where JSON-LD can improve the situation – it provides for listing information in a more key:value-like format, making it easier for front end developers not interested in the RDF relations to utilise. But this leads to additional complexity in the spec and parsing requirements, so we have some further work to complete: * remove angle brackets from blank nodes * use type coersion to move types out of main code * use language coersion to omit languages Our code is currently available in our repository, and we will request that our parsers and serialisers get added to RDFlib or to RDFextras once they are complete (they are still in development at present). To further assist in representing bibliographic information in JSON, we also intend to implement BibJSON within JSON-LD; this should provide the necessary lined data functionality where necessary via JSON-LD support, whilst also enabling simpler representation of bibliographic data via key:value pairs where that is all that is required. By making these options available to our users, we will be able to gauge the most popular representation format. Regardless of format used, a critical consideration is that of stable references to data. Without this maintaining datasets will be very hard. To date, the British Library data for example does not have suitable identifiers. However, the BL are moving forward with applying identifiers and will be issuing a new version of their dataset soon, which we will take as a new starting point. We have provided a list of records that we have identified as non-unique, and in turn the BL will share the tools they use to manage and convert data where possible, to enable better community collaboration.

Getting more open datasets

We are building on the success of the BL data release by continuing work on our CUL and IUCr data, and also by getting more datasets. The latest is the Medline dataset; there were some initial issues with properly identifying this dataset, so we have a previous blog post and a link to further information, the Medline DTD and specifications of the PubMed data elements to help.

The Medline dataset

We are very excited to have the Medline dataset; we are currently working on cleaning so that we can provide access to all the non-copyrightable material it contains, which should represent a listing of about 98% of all articles published in PubMed. The Medline dataset comes as a package of approximately 653 XML files, chronologically listing records in terms of the date the record was created. This also means that further updates will be trackable as they will append to the current dataset. We have found that most records contain useful non-copyrightable bibliographic metadata such as author, title, journal, PubMed record ID, and that some contain further metadata such as citations, which we will remove. Once this is done, and we have checked that there are unique IDs (e.g. that the PubMed IDs are unique) we will make the raw CC0 collection available, then attempt to get it into our Bibliographica instance. We will then also be able to generate visualisations on our total dataset, which we hope will be approaching 30 million records by the end of the JISC Open Bibliography project.

Displaying bibliographic records

Whilst Bibliographica allows for display of individual bibliographic records and enables building collections of such records, it does not yet provide a means of neatly displaying lists of bibliographic records. We have partnered with Jim Pitman of Berkeley University to develop his BibServer to fit this requirement, and also to bring further functionality such as search and faceted browse. This also provides further development direction for the output of the project beyond the July end date of the JISC Open Bibliography project.

Searching bibliographic records

Given the collaboration between Bibliographica and BibServer on collection and display of bibliographic records, we are also considering ways to enable search across non-copyrightable bibliographic metadata relating to any published article. We believe this may be achievable by building a collection of DOIs with relevant metadata, and enabling crowdsourcing of updates and comments. This effort is separate to the main development of the projects, however would make a very good addition both to the functionality of developed software and to the community. This would also tie in with any future functionality that enables author identification and information retrieval, such as ORCID, and allowing us to build on the work done at sites such as BIBKN

Disambiguation without deduplication

There have been a number of experiments recently highlighting the fact that a simple LUCENE search index over datasets tends to give better matches than more complex methods of identifying duplicates. Ben O’Steen and Alex Dutton both provided examples of this, from their work with the Open Citation project. This is also supported by a recent paper from Jeff Bilder entitled “Disambiguation without Deduplication” (not publicly available). The main point here is that instead of deduplicating objects we can simply do machine disambiguation and make sameAs-ness assertions between multiple objects; this would enable changes to still be applied to different versions of an object by disparate groups (e.g. where each group has a different spelling or identifier, perhaps, for some key part of the record) whilst still maintaining a relationship between the two objects. We could build on this sort of functionality by applying expertise from the library community if necessary, although deduplication/merging should only be contemplated if there is a new dataset being formed which some agent is taking responsibility to curate. If not, better to just cluster the data by SameAs assertions, and keep track of who is making those assertions, to assess their reliability. We suggest a concept for increasing collaboration on this sort of work – a ReCaptcha of identities. Upon login, perhaps to a Bibliographica or another relevant system, a user could be presented with two questions, one of which we know the answer to, and the other being a request to match identical objects. This, in combination with decent open source software tools enabling bibliographic data management (building on tools such as Google Refine and Needlebase), would allow for simple verifiable disambiguation across large datasets.

Sustaining open bibliographic data

Having had success in getting open bibliographic datasets and prototyping their availability, we must consider how to maintain long term open access. There are three key issues:

Continuing community engagement

We must continue to work with the community, and to provide explanatory information to those needing to make decisions about bibliographic data, such as the OpenBiblio Principles and the Open BIbliographic Data guide. We must also ensure we improve resource discovery by supporting the requirement for generating collections and searching content. Additionally, quality bibliographic data should be hosted at some key sites – there are a variety of options such as Freebase, CKAN, bibliographica – but we must also ensure that community members can be crowdsourced both for managing records within these central options and also for providing access to smaller distributed nodes, where data can be owned and maintained at the local level whilst being discoverable globally.

Maintaining datasets

Dataset maintenance is critical to ongoing success – stale data is of little use to people and disregard for content maintenance will put off new users. We must co-ordinate with source providers such as the BL by accepting changesets from them and incorporating that into other versions. This is already possible with the Medline data, for example, and will very soon be the case with BL updates too. We should advocate for this method of dataset updates during any future open data negotiations. This will allow us to keep our datasets fresh and relevant, and to properly represent growing datasets. We must continue to promote open access to non-copyrightable datasets, and ensure that there is a location for open data providers to easily make their raw datasets available – such as CKAN. We will ensure that all the software we have developed during the course of the project – and in future – will remain open source and publicly available, so that it will be possible for anyone to perform the transforms and services that we can perform.

Community involvement with dataset maintenance

We should support community members that wish to take responsibility for overseeing updating of datasets. This is critical for long term sustainability, but hard to find. These people need to be recruited and provided with simple tools which will empower them to easily maintain and share datasets they care about with a minimal time commitment. Thus we must make sure that our software and tools are not only open source, but usable by non-team members. We will work on developing tools such as ReCaptcha for disambiguation, and on building game / rank table functionality for those wishing to participate in entity disambiguation (in addition to machine disambiguation).

Critical mass

We hope that by providing almost 30 million records to the community under CC0 license, and with the support of all the providers that made this possible, we will achieve a critical mass of data, and an exemplar for future open access to such data. This should provide the go-to list of such information, and inspire others to contribute and maintain. However, such community assistance will only continue for as long as there appears to be reasonable maintenance of the corpus and software we have already developed – if this slips into disrepair, community engagement is far less likely.

Maintaining services

The bibliographica service that we currently run already requires significant hardware to run. Once we add in Medline data, we will require very large indexes, requiring a great deal of RAM and fast disks. There is therefore a long term maintenance requirement implicit in running any such central service of open bibliographic data on this scale. We will present a case for ongoing funding requirements and seek sources for financial support both for technical maintenance and for ongoing software maintenance and community engagement.

Business cases

In order to ensure future engagement with groups and business entities, we must make clear examples of the benefits of open bibliographic data. We have already done some work on visualising the underlying data, which we will develop further for higher impact. We will identify key figures in the data that we can feed into such representations to act as exemplars. Additionally, we will continue to develop mashups using the datasets, to show the serendipitous benefit that increases exposure but is only possible with unambiguously open access to useful data.

Events and announcements

We will continue to promote our work and the efforts of our partners, and advocate further for open bibliography, by publicising our successes so far. We will co-ordinate this with JISC, BL, OKF and other interested groups, to ensure the impact of announcements by all groups are enhanced. We will present our work at further events throughout the year, such as attendance and sessions at OKCon, OR11 and other conferences, and by arranging further hackdays.

Comparative Serialisation of RDF in JSON

- May 4, 2011 in BibServer, Data, inf11, jisc, JISC OpenBib, jiscEXPO, jiscopenbib, model, OKFN Openbiblio, ontology, outputs, progress, progressPosts, rdf, Semantic Web

This is a comparison of RDF-JSON and JSON-LD for serialising bibliographic RDF data. Given that we are also working with BibServer we have taken a BibJSON document as our source data for comparison. The objective was to both understand these two JSON serialisations of RDF and also to look at the BibJSON profile to see how it fits into such a framework. Due to limitations of the display of large plain-text code snippets on the site, we have placed the actual content in this text file which you should refer to as we go along. We used a BibJSON document, which comes from the examples on the BibJSON homepage. When converting this into the two RDF serialisations we invent a namespace
http://www.bibkn.org/bibjson/terms/
This namespace provisionally holds all predicates/keys that are used by BibJSON and are not immediately clearly available in another ontology. These terms should not under any circumstances be considered definitive or final, only indicative. Now consider the RDF-JSON serialisation Some key things to note about this serialisation:
  • There is no explicit shortening of URIs for predicates into CURIEs, all URIs are instead presented in full.
  • The subject of each predicate is a JSON object with up to 4 keys (value, type, datatype, lang). This means that it is not easy for the human eye to pick out the value of a particular predicate.
  • Of the two RDF serialisations, this is by far the most verbose
  • It is relatively difficult for a human to read and write
Compare this with the equivalent JSON-LD serialisation: Some things to note about this serialisation:
  • It has a clear treatment of namespaces
  • It may be slightly inaccurate, as there are some parts of its specification which are ambiguous – feedback welcome
  • The object values cannot be taken as the value of the predicate, as they may contain datatype and/or language information in them, or may be surrounded by angled brackets.
  • It is relatively easy for a human to read and write
Both serialisations are capable of representing the same data, although JSON-LD is far more terse and therefore easier to read and write. It is not, however, possible to reliably treat JSON-LD as a pure list of key-value pairs in non-RDF aware environments, as it includes RDF type and language semantics in the literal values of objects. RDF-JSON does not suffer from this same issue within the object literals, but in return its notation is more complex. A serious lacking in RDF-JSON is explicit handling of CURIEs and namespaces, and it could benefit from adopting the conventions laid out in JSON-LD – this may bring the choice of which serialisation to use down to preference rather than relying on any significant technical differences. Each of the formats also comfortably represents BibJSON, and with the extensive lists of predicates provided in that specification it would be straightforward enough to do a full and proper treatment of BibJSON through one of these routes.

Getting open bibliographic data from (UK)PMC / PubMed

- May 3, 2011 in Bibliographic, Data, inf11, jisc, JISC OpenBib, jiscEXPO, jiscopenbib, OKFN Openbiblio, progress, progressPosts

For some time now, the JISC Open Bibliography project team has been attempting to get open bibliographic data from (UK)PMC / PubMed. Everyone involved (Robert Kiley – Wellcome, Ben O’Steen, Peter Murray-Rust – JISC OpenBib, Jeff Beck – NIH/NLM/NCBI, Johanna McEntyre) has worked hard to achieve this, but attempts have been hampered by ambiguities and technical restrictions. The purpose of this post is to clarify and highlight these issues as examples of stumbling blocks on any path to linked open data, to specify what it is we are trying to achieve at present, and learn how to improve this process.

WHAT WE ARE TRYING TO DO

Closed access to bibliography is dangerous – it actually holds back the scientific discovery process. We therefore believe it is important to have an authoritative Open collection of bibliographic records. This acts as a primary resource for the community which they can use for normalisation, discovery, annotation, etc. We seek confirmation that we can have programmatic access to the approximately twenty million or so records in PubMed. NCBI for example should be able to say: “these are the articles which we have in Pubmed” without breaking any laws or contracts. These articles would be identified by their core bibliographic data.

PROBLEMS

  • We received an original email last year stating that we could have such access to PubMed, but it has become unclear what PubMed is.
  • Identifying the correct content is not straightforward – are we talking about PMC / UKPMC / PubMed / Open Access subset?
  • What licenses are involved and on which subsets do open licenses such as CC0 apply?
  • These datasets are very large, so incremental and recordset-by-recordset requests to servers have resulted in roadblocks such as timeouts and errors.

WHAT DATASET ARE WE TALKING ABOUT

  • The 2 million articles in PMC are NOT all open access. There are 251,129 articles (approx 12% of PMC) that are in the open access subset.
  • Although there are 2 million or so articles in PMC which anyone can look at, print out etc, only 251k of these have an OA licence which allows people to re-use the content, including creating derivative works.
  • PMC and UKPMC have approximately the same full-text content. There are a small minority of journals which refused to allow their content to be mirrored to UKPMC.
  • The distinction between “public access” content and “open access” articles (i.e 0.25m articles) is irrelevant, as we are only interested in the bibliographic record, not the content.
  • For current purposes PMC and UKPMC can be used interchangeably.
  • PMC is only a subset of PubMed – which contains about twenty million records, the totality of content in NIH / NLM / NCBI.
  • The MEDLINE dataset is a subset of about 98% of PubMed.
  • However we believe, as per previous discussions, that the legal situation applies equally to PubMed as to the PMC.
  • So we are looking for every bibliographic record in PubMed (or MEDLINE if that is easier to acquire).

WHAT DO WE MEAN BY BIBLIOGRAPHIC RECORD

  • “Bibliography” is sometimes used as synonymous with “a given collection of bibliographic records”. Consider “the bibliographic data for Pubmed”; what we are interested in is enumerating individual bibliographic records.
  • “Citation” often refers to the reference within the fulltext to another publication (via its bibliographic record). The list of citations is not in general Open except in Open Access journals.
  • For the purposes of Open Bibliography we are restricting our discussion to what we call core bibliographic data (described in the open bibliographic data principles)
  • We regard the core bibliographic data as uncopyrightable, and generally acknowledged to be necessarily Open.
  • This core bibliographic data is what we mean by the bibliographic record.
  • Such records are unoriginal and inevitable, being the only way of actually identifying a work.
  • Although collections of bibliographic data are copyrightable (at least in Europe) because they are the result of the creative act of assembling a set of records, the individual records are not.
  • There is no creative act in compiling the list of bibliographic records held by NCBI/Pubmed as it is an exhaustive enumeration.
  • We believe that there is no moral case and probably no legal case for regarding these as the property of the publisher.

WHAT DO WE NOT MEAN BY BIBLIOGRAPHIC RECORD

  • As abstracts appear to be copyrightable we do not include abstracts, or annotations.
  • If it is not in the open bibliographic principles, we do not consider it to be in the bibliographic record.

WHAT WE HOPE TO GET NOW

  • Due to issues with programmatic access to PMC / PubMed dataset (restrictions on requests to the servers that contain them, we request a dump of the MEDLINE dataset.
  • This represents about 98% of PubMed which we believe is or should be available as CC0.
  • As MEDLINE also has incremental updates, we request ongoing access to those, to allow change tracking and synchronisation.
  • We have have filled in the automatic leasing form for the MEDLINE set a few times since February, (most recent attempt was at the end of April.)
  • We hope that the position is now clearly stated in this post, and await confirmation.
  • Upon agreement we look forward to receiving the XML files containing the MEDLINE dataset, from which we will extract the aforementioned unoriginal and re-usable bibliographic data.
We look forward to resolving this, to receiving the data, and to helping to make it openly available.

Bibliographica and Edinburgh International Science Festival

- April 11, 2011 in Data, event, inf11, jisc, JISC OpenBib, jiscEXPO, jiscopenbib, OKFN Openbiblio, progressPosts, WIN

This weekend I was trying to build a useful search tool to help my wife find interesting events on at the Edinburgh International Science Festival. One problem was that the dataset was poor, and the descriptions did not always give a lot of detail. I attempted to rectify this by hooking up the events to bibliographica. Now, you can filter events then select “more” to see further details and a list of relevant publications based on the event speakers and the event theme; this can give a slightly better idea of what might be going on, as you can review the published work of those involved. http://eisf.cottagelabs.com Unfortunately, the data does still have quite a few errors, and I have not ensured that names tie up properly, so the results are not always perfect. But still, it is quite a good demonstration. It would be even better with journal articles to search across.

open theses at EURODOC

- April 7, 2011 in Bibliographic, communityBenefits, inf11, jisc, JISC OpenBib, jiscEXPO, jiscopenbib, progress, progressPosts, WIN

#jiscopenbib #opentheses On Friday 1st April 2011, Mark MacGillivray, Peter Murray-Rust and Ben O’Steen remotely attended the EURODOC conference in Vilnius, Lithuania in order to take part in an Open Theses workshop locally hosted by Daniel Mietchen and Alfredo Ferreira (funded by the JISC Open Bib project to attend in person). During the workshop we began laying the foundations for open theses in Europe, discussing with current and recently finished postgraduate students and collecting data from those present and from anyone else interested. As described by Peter prior to the event:
As part of our JISCOpenBIB project we are running a workshop on Open Theses at EURODOC 2011. “We” is an extended community of volunteers centered round the main JISC project. In that project we have developed an approach to the representation of Open Bibliographic metadata, and now we are extending this to theses.

Why theses? Because, surprisingly, many theses are not easily discoverable outside their universities. So we are running the workshop to see how much metadata we can collect on European theses. Things like name, university, subject, datae, title – standard metadata.

We have the beginnings of a dataset at: https://spreadsheets.google.com/ccc?key=0AnCtSdb7ZFJ3dHFTNDhJU0xfdGhIT01WeTBMMDZWOGc&hl=en_GB&authkey=CJuy4owB The content of this datasheet will hopefully be used to populate an open theses collection in bibliographica, and in addition it is powering a mashup that will allow us to view at a glance the theses that have been published across the world, and where possible a link to the work itself: http://benosteen.com/eurodoc.html We also have a survey to fill in, to collect opinion around copyright issues for current / soon to be published theses, based at: http://openbiblio.net/opentheses-survey/ The data collected by this survey is available at: https://spreadsheets.google.com/ccc?key=0AnCtSdb7ZFJ3dDN1cHQ3TDJpYWRaWmkxWlFDS2lMWXc&hl=en_GB&authkey=CMKN-O8I#gid=0
