Dear Miel,

Could you present this in the next SIG?😁

    Dear Miel,

    Thank you for your comments.

    Having a JSON-LD serialization seems useful, given the increasing
    adoption of this encoding format. We can start considering its
    implementation once the RDFS is approved by CRM SIG.


When done right, it can make complex models like CIDOC-CRM look a lot less scary. I think the goal should not be a complete implementation of CIDOC-CRM in a single context, but rather lead to an entry-level format that can be expanded when necessary (json-ld allows you to do this). I'm working on similar examples for PREMIS OWL.


    About SHACL: do you mean using SHACL for schema validation, or for
    defining constraints/requirements over crm-compliant RDF graphs? I
    guess the latter. This is interesting as well, but it also
    requires careful design and thinking/discussions on what types of
    constraints to consider and define.


same here. I think both are very useful, but the latter can provide an easy to adopt, entry-level view on CIDOC-CRM. In any case, you cannot capture an open ontology in a single SHACL schema; they will always be one or more constraint views aimed at implementation and easy adoption.

In fact, this is what we have done in Belgium with the OSLO programme by defining a consensus-driven application profile of cidoc-crm. You can find JSON-LD and SHACL implementations at the bottom of this page: https://data.vlaanderen.be/doc/applicatieprofiel/cultureel-erfgoed-event/#shacl <https://data.vlaanderen.be/doc/applicatieprofiel/cultureel-erfgoed-event/#shacl>

Best,

Miel


    Best regards,
    Pavlos

        Thanks to all involved for this contribution. This is indeed
        an important step towards adoption.

        I was wondering: is a SHACL profile and a JSON-LD context
        being considered?

            Dear all,

            The "Resources" page of the CIDOC-CRM website
            (http://www.cidoc-crm.org/versions-of-the-cidoc-crm
            <http://www.cidoc-crm.org/versions-of-the-cidoc-crm>) has
            been recently updated to include:

            - An *RDFS implementation* (_not yet approved by SIG_) of
            the last official version of CIDOC-CRM (7.1.1). The link
            points to a gitlab web page which also includes the
            policies adopted for generating the RDFS file.
            - An *XML file* for each version of CIDOC-CRM, including
            the classes and properties of the corresponding version.
            - An *HTML page* for each version of CIDOC-CRM, containing
            declarations for all classes and properties (facilitating
            navigation to the classes and properties of each version).
            - An HTML page for each version of CIDOC-CRM, containing
            *translations *and *versioning *information of all classes
            and properties.

            We (at FORTH) believe that the above will facilitate the
            adoption of CIDOC-CRM.

            We will start gathering comments about errors,
            improvements, etc., so please do not hesitate to provide
            your critical feedback.

            All the above will be presented and discussed during the
            next CIDOC-CRM meeting.

            Best regards,
            Pavlos
