• PROV-N Cheat Sheet This is a quick “cheat sheet” for the PROV-N syntax.
• What are good PROV-N prefixes?

  In this blog post we explore the role of PROV-N prefixes and how to decide on a good namespace to use your own custom provenance terms.

  Most examples of PROV-N use example prefixes like:

  prefix ex <http://example.com/>
  prefix exg <http://example.org/government>
  

  These example domains are explicitly reserved globally for all kinds of examples and training material, and deliberately do not have any content, advertisement or affiliations.

  Assume you are writing the provenance of a student group exercise, should you be using the prefix/namespace ex and example.org to define agents/entities/relationship and your own attribute types?

• Validating and visualising PROV

  This blog post gives a gentle PROV-N introdction and then explores tools for validating and visualising PROV.

  One of the advantages of W3C PROV having a common data model is that it can be serialized, or written out, in multiple file formats. The PROV family of W3C specifications describe mappings PROV-XML and PROV-O (which, being based on OWL2 itself has multiple serializations, for Linked Data including RDF formats Turtle and JSON-LD.

  In addition to these standard approaches we also have PROV-JSON and PROV-JSONLD which could be well-suited for Web applications. All of these can in theory be mapped to each-other through the common PROV Data Model and the use of URIs as Linked Data global identifiers.
