Contributing to the Diagram

First, make sure that you publish data according to the
Linked Data principles.
We interpret this as:

• There must be resolvable http:// (or https://) URIs.
• They must resolve, with or without content negotiation, to RDF datum in one of the popular RDF format
  ( RDFa , RDF / XML , Turtle , N – Triples ) .
• The dataset must contain at least 1000 triples. ( Hence , your FOAF file is qualify most likely does not qualify . )
• The dataset must be connected via RDF links to a dataset that is already
  in the diagram. This means, either your dataset must use URIs from the other dataset,
  or vice versa. We arbitrarily require at least 50 links.
• Access of the entire dataset is be must be possible viaRDF crawling, via an RDF dump, or via a SPARQL endpoint.

The process for adding datasets is still under development, please
