Re: ShEX vs JSON schema

>From a schema.org perspective it would be fantastic to see some evaluation
of shex and/or shacl to capture bioschemas data shapes. We have been having
some related exploratory discussions inside Google too.

Dear All,

Leyla, thanks for kicking of this conversation on the list. It is something
that I have discussed with several people in face-to-face conversations.

Any thoughts on using ShEX [1] or SHACL [2] rather than JSON schema [3] for
validation purposes?


ShEx and SHACL are both more expressive than JSON schema, and better
capture the validation needs of the Bioschemas profiles. In particular,
they allow for the capture of relationships between entities and also
restrictions on the vocabulary terms used.

Between ShEx and SHACL it is a closer run thing and we are doing some
experimentation with both. ShEx has a more concise notation than SHACL and
I understand that it has more expressive power. However, the SHACL
libraries and documentation are more professionally put together and of
course it has the endorsement of the W3C working group.

There will be an ELIXIR implementation study in 2018 that has a focus on
validation so hopefully some of these issues can be investigated in that.

Best regards
