The new CSV on the Web Working Group is an important step in that direction, following on the heels of efforts such as R2RML. It’s about providing metadata about CSV files, such as column headings, data types, and annotations, and, with it, making it easily possible to convert CSV into RDF (or other formats), easing data integration

In SMW 1.6.0, stores are required to accept updates and queries that do not specify a graph but it is planned to remove this limitation in the future.

The first line tells SMW to use the SPARQL store implementation to store data (instead of the SMWSQLStore2 that is the default). The remaining lines provide the relevant service locations, where the last line can be omitted if not applicable. By default, SMW will use a generic SPARQL connector that is based on recent SPARQL documents. Some RDF databases might not be fully compatible with this or might need special tweaks to make use of advanced, non-standard features. For this purpose, it is possible to change the SPARQL connector that SMW uses by setting the variable $smwgSparqlDatabase. In SMW 1.6.0, there is only one special connector:

$smwgSparqlDatabase = 'SMWSparqlDatabase4Store';
