License declaration in vocabularies

Linked Open Vocabularies (LOV) collects curated vocabularies in RDF and exposes them with an API and SPARQL endpoint.
As of today, 469 vocabularies are in the database. The raw file can be downloaded with the metadata (a TTL file) or a big dump with all the vocabularies contained (as a handy .nquads file).


RDF Transcode in Windows Explorer context menu

Today I have programmed a tool that offers a context menu in Windows 7 to transcode an RDF file along the different syntaxes as long as to verify its validity. In one click!

It converts from-to the following sytnaxes: RDF/XML, TURTLE, NTRIPLES, NQUADS and HDT.
It is a Windows 7 tool. After all, Linux users have plenty of equivalent tools to enjoy from their command line.

Until I move the project to github, you may want to download the installer here.

The name of the service is as follows:
