I’ve just completed a first release of doap:store, a user-driven directory of DOAP projects.
The goal is to build a database of computing projects that have a DOAP description – as does the Semantic Web Apps and Demo service, but not only SW related here – , thanks to Ping The Semantic Web service. Thus, there is no need to register, projects will be fetched from PTSW, that will get them eitheir by pings, or even better, thanks to Semantic Radar plugin for Firefox when people browse the Web.
Then, doap:store provides a common search engine and browsing interface for these decentralized project description, while authors keep control over their data. Data is updated each time PTSW has a new ping for it (in the future, PTSW should store new pings only if the document has changed, so updated will be made only for real document updates).
From the technical side, it’s using 3store for the storage and of course SPARQL for the queries.
I hope this kind of tool can help to outreach DOAP for developers, and SW in general, as thanks to Semantic Radar, anyone can contribute to build this directory.
