The experimental branch of shacl-engine is now introducing features related to the upcoming SHACL 1.2 specifications, along with some proposals still under discussion. These additions are in an early stage of development, meaning they may be incomplete or unstable. But you can start playing at the experimental instance of SHACL Playground.
The Data Shapes Working Group, in which I also participate, is busy with the work on the SHACL 1.2.
A few core features are already very much settled, while others are still discussed.
The experimental branch of shacl-engine serves as one of the testing grounds for these ideas.
If you’re curious to try them out, head over to the experimental instance of SHACL Playground. For details on the implemented features, check the shacl-engine README, and for usage examples, explore the test folder.
