QUDT - Quantities, Units, Dimensions and dataTypes - public repository
This QUDT1 public repository contains the schema and vocabulary source files for the graphs making up the QUDT collection. It is probably the most convenient way for software developers to include the QUDT ontologies in their work, and is the most up-to-date. However, for those who prefer the linked data world, each QUDT graph is also available in both a versioned and an unversioned form on the qudt.org website.
Our current plan is to deliver this material in even more powerful ways. The website will eventually host an engine supporting SPARQL and GraphQL queries, and fully resolvable URIs at the individual class and instance level will be available online.
We encourage you to get involved. If you have particular needs or see errors, please create an Issue and/or make changes or additions yourself (please see our Wiki for more detailed instructions.)
Release 2.1 of QUDT is being published in increments. The first increment is a release of the schemas and base vocabularies for units, quantity kinds and dimension vectors. Please check this repository or the qudt.org website for the latest updates.
