Valueflows vf vocabs

Valueflows icon

Here is the current release spec, which also includes concepts:

Some specific links of interest for devs:

  • Classes and Properties. This is the standard specification format, which includes the VF namespace only. (We have tried to re-use other vocabularies when we can.) For a view of the whole model with references to the vocabularies used, see this diagram.
  • Other Namespaces/Terms. This references the other vocabulary elements that are also necessary for a complete value flows economic model.
  • RDF Reference This is the "turtle" file that is the system of record source for the specification. It includes only the VF namespace.
  • GraphQL Reference. This is actively used, and maintained mostly by the projects using it. It includes the whole vocabulary.
  • JSON-schema Reference. This is out of date, but will be updated upon request if a project wants to use it. It includes the whole vocabulary.
  • Procedures for moving changes to the website.
