RDF data
30Sep07
What are the possible RDF data sources?
- triple stores : locals and distant, the last ones can be queried using the SPARQL protocol
- local rdf datasets or data available in RDF : loaded in memory
- intermediate layer doing the mapping between the native/legacy data representation (DB or LDAP for example) and an exposed RDF view.=> D2RQ/D2R , SquirrelRDF, …
- web site containing semantic data : RDFa, microformats, eRDF, … These information can be extracted using GRDDL for example.
- scrapping applications : Solvent

We had some thoughts on RDF sources, as well. In case you are interested, you may wish to have a look at [1].

RDF data can be a delivery format too (irrespective of the storage format) like the one provided by Open Directory Project.
It should be simple to materialize RDF data from relational data by adding some metadata information.
