Stencil graffiti website goes semantic

As a first step towards releasing the information on my stencil graffiti website as Linked Open Data, I have now created XHTML+RDFa files for all graffiti. They can be found in the directory http://graffiti.freiburg.bplaced.net/lod/, or by clicking on the RDFa icon in each entry. These files contain only two pieces of information so far (not counting ID and licence): place and date. Now that they have been normalised (to the W3C Basic Geo and Dublin Core vocabulary, respectively) and cast in standard RDFa syntax, it should be easy to query and analyse this data, and to re-use it in mashups.

I did a short presentation on this conversion recently, the slides of which can be found on SlideShare (in German). The next steps are obvious: there is still a lot of information on the website that could be normalised, expressed in RDFa, and added to the XHTML files. Once I’ve got round to that I’ll post about it. As a good resource for getting started with Linked Open Data, I recommend Ed Summers’s recent paper “Linking Things on the Web: A Pragmatic Examination of Linked Data for Libraries, Archives and Museums”.
