Call for Participation in SHACL Community Group

The SHACL Community Group has been launched:

The mission of the SHACL Community Group is to continue the development of SHACL-related specifications and to support the further adoption of SHACL after the W3C Data Shapes Working Group has ended. Desirable outcomes include the development of educational material (primers, best practices), the application of SHACL to frequently used RDF vocabularies, libraries of constraint components for common constraint types, improved integration with established technologies such as JavaScript, further work on theory and practice around SHACL rules, a compact SHACL syntax, and a SHACL internet protocol. Additional work may go into delivering “de-facto standard” fixes to some gaps left in the current SHACL specifications (e.g., handling recursion, and addressing more comprehensive syntax checks).

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2017-05-31 by Ted Thibodeau. The following people supported its creation: Ted Thibodeau, Sandro Hawke, Pano Maria, Dimitris Kontokostas, Simon Steyskal, Irene Polikoff, Nicky van Oorschot, jack hodges, Holger Knublauch, Mohamed ZERGAOUI, Tomislav Novak, Jose Emilio Labra Gayo, Peter Bruhn Andersen. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
