Linked Open Vocabularies (LOV) Hosting

- March 19, 2012 in datacatalog, linked-open-data, vocabulary, webapp

Title: Linked Open Vocabularies (LOV) Project Coordinator: Bernard VATANT, Pierre-Yves VANDENBUSSCHE Contact Email: bvatant A_T gmail.com Project Description: Vocabularies we are about are the many dialects (RDFS and OWL ontologies) used in the growing linked data Web. Most popular ones form now a core of Semantic Web standards de jure (SKOS, Dublin Core, FRBR …) or de facto (FOAF, Event Ontology …). But many more are published and used. Not only linked data leverage a growing set of vocabularies, but vocabularies themselves rely more and more on each other through reusing, refining or extending, stating equivalences, declaring metadata. LOV project aims at : - providing easy access methods to this vocabularies ecosystem, and in particular by making explicit the ways they link to each other - providing metrics on how they are used in the linked data cloud - helping to improve their understanding, visibility, usability, and overall quality. LOV provides a technical platform for search and quality assessment among the vocabularies ecosystem. This project is currently hosted by Mondeca company http://labs.mondeca.com/dataset/lov, but we are now convinced that this project should be integrated in a public organization which can ensure this project/resource sustainability. We hope to find in Open Knowledge Foundation a long term solution for this valuable project and resources. Tags: okfn-project-proposal, datacatalog, opendata, linked-open-data, webapp, visualisation, vocabulary Resources: To achieve our vision, we need a hosting server to be independent of any private interest. We currently have the human resources required to support this project but are open to welcome anyone who is interested in. Conformance with OKFN Project Criteria: “We agree to the OKFN project criteria”. Please, let us know if OKFN could host the project or not. Sincerely, Pierre-Yves Vandenbussche and Bernard vatant

Mini visualization app that shows me how much of any CD or DVD price goes to Artists

- January 15, 2012 in Data, for-hackday, visualisation, webapp

Mini visualization app that shows me how much of any CD or DVD price goes to artists. Could also show:
  • Amount going to label / producers
  • Amount going to promotion and advertising
  • Other ways to contribute to the artist

GiveMeTheDamnSchema.org – Find Data Schemas Fast

- November 30, 2011 in Data, opendata, webapp

Idea that came up during workshop at Open Gov Data Camp was need for a simple place to find data schemas (discussion came up when discussing RDF schemas but is generally applicable). Suggestion was http://GiveMeTheDamnSchema.org/ but could shorten to http://GiveMeTheSchema.org/

Open CAPTCHA

The OKFN could have a go at building a service like reCAPTCHA, but make the learning models available for reuse as open data.

emergencydata.org, a data catalogue for crises

- July 19, 2011 in ckan, webapp

Create a catalogue for data sources which are created during crisis events, such as natural disasters. This could include:
  • Sattelite imagery
  • mapping data
  • ad-hoc contact lists

Add a BitTorrent tracker to thedatahub

- July 13, 2011 in ckan, thedatahub, webapp

Now that thedatahub.org deals with data storage as well as being a catalogue, adding torrent support seems very useful. Popular large datasets are expensive to distribute when providers are on capped Internet plans. Peer-to-peer file sharing seems like a very effective manner to minimise costs.

Google Books for OER

- June 2, 2011 in code, education, oer, open-education, webapp

Problem OER content is widely distributed over many sites and catalogues are generally teacher centric. Moreover, lots of the OER catalogues seem to be fairly teacher orientated. A learner-centric OER space I was thinking of providing something slightly more learner centric. Kids would be sent to a URL, which would have content displayed nicely for them. They could annotate it, highlight things or bookmark pages. The system would world by indexing lots of content from the structured data that exists in many OER catalogues and other places such as Project Gutenberg. It would then focus on delivering content in a highly-readable, attractive manner. There would be also useful CSS for print and mobile devices. Some other possibilities, to tie it into the classroom/learning process:
  • A teacher might like to create reading lists for his class. Like a Youtube playlist, but rather than whole books, need to be able to select page ranges.
  • Another teacher would like to provide questions for her students at each section.
  • One-shot authentication, to enable children to collaborate without the issues of sign in processes
  • Leaning management system friendly
www.opentextbook.org could become a place that syndicates lots of content in all the repositories and catalogues that already exist. Examples http://www.20thingsilearned.com/ is a great example of displaying ebook content in the browser, plus its code is open source code. One problem is that it is very HTML5-centric, meaning that it probably wont display very well on old browsers on old machines. behind

Wiki-like editing service for documents in HG/Git

- April 12, 2011 in hg, texts, tools, webapp

We should have a service that allows users to edit documents (in whatever syntax, agnostic) in a mercurial repo via a web user interface. The service should handle user management, commits and, possibly, branches.
