ShEx 2.0 Candidate Release

The ShEx Community Group would like to invite public review of three deliverables:

• Shape Expressions (ShEx) Primer http://shex.io/shex-primer/
• Shape Expressions Language 2.0 http://shex.io/shex-semantics/
• Shape Expressions Test Suite https://github.com/shexSpec/shexTest/ including:
  • 337 schemas in three representations:
    • ShExC: compact syntax
    • ShExJ: JSON-LD 1.0 syntax
    • ShExR: Turtle syntax
  • 927 validation tests.
  • 101 ShExC negative syntax tests
  • 7 negative structure tests.

The test suite has a Implementation Report including 4 of the 5 implementations: http://shexspec.github.io/shexTest/reports

For feature requests please note the features in the 2.1 milestone: https://github.com/shexSpec/shex/issues?q=is%3Aopen+is%3Aissue+milestone%3A2.1

Many of these have been implemented and tested but are not in this version of the specification. We invite feedback from the community on issues with the documents or tests, new feature prioritization and new feature use cases.
