However, there were one thing on the Opera Community that didn't have well-recognised schema that I could use, and that was our photo albums. For this, I created a schema, but as it was something that many others could use, a number of people from the Semantic Web Community came together in an online meeting to discuss and improve this schema.
The result is a new schema, with some new properties and classes. It is allready in use here on the Opera Community, but we also hope that the rest of the people developing for the Semantic Web will use it, and that's quite likely to happen, given the consensus behind it.
Specifically, the data can be queried with the SPARQL Engine, but you can also have a look behind the new RDF link in your albums, and see how for example Eskil's Svalbard Gallery looks. Be sure to enter titles and description whereever it is possible, someone will find it useful!
