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 data in one of the popular RDF formats (RDFa, RDF/XML, Turtle, N-Triples).
• The dataset must contain at least 1000 triples. (Hence, your FOAF file 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 must be possible via RDF crawling, via an RDF dump, or via a SPARQL endpoint.

You may add a dataset by submitting it at this form here The process for adding datasets is still under development, please contact John P. McCrae for any issues.
