Also complexity increases when you have an object E22 which then becomes a feature E25 in another object, e.g. a plank of wood becomes part of a laminated board for a manuscript. A new identifier would be necessary after the part addition event for the resulting feature. People (including me, regularly) get confused with the classes at that point as the new identity for what seems to be the same thing feels counter-intuitive.

All the best,

The issue was just about the scope note and "objects and sword". I saw an example of E24 being used with E9 and I wondered whether the scope note was misleading.
E24 says

"This class comprises, besides others, human-made objects, such as a sword, and human-made features, such as rock art."

Thanks,

    Although I like "stuff" more than "thing" because it sounds more
    generic, although they are more or less synonyms, here is a comment

    stuff> for the complete text):
    /
    /
    /*Thing*/

    We use the general noun /thing/ more commonly in speaking than in
    writing.

    It is most commonly used to _refer to physical objects_, but we also
    use /thing/ to refer to i_deas, actions and events_

    ...

    /*Stuff*/

    /Stuff/ is one of the most common nouns in speaking. It is more
    informal than /thing/. It is _not at all common in writing_.

    ...

    In conclusion, there should be another word for the matter, as
    "thing" may convey a dubious meaning and "stuff" is too
    colloquial and of difficult translation in other languages ; in
    doubt, "thing" looks better to me.
    In Italian I would use the term "cosa" which applies both to
    physical and to immaterial things and translates either English
    terms; probably the same happens to "chose" in French.

        Dear both,
        I early times before the first ISO version (pre 2004) the name
        of the class E70 Thing was E70 Stuff. It was changed because,
        according to Nick Crofts, the term 'stuff' could not be
        translated properly into French. If you check CIDOC CRM version
        3.4.9  you will see that. Personally,  I think that was a bad
        decision.  Shakespeare writes "The stuff dreams are made of".
        "Thing" is a bad choice since it may be confused with "Object".

        Best,
        Christian-Emil

        Dear Dominic,

        Yes this is as it should be. This class is the super set of the
        human made object and human made feature. As such its instances
        include both of its child classes’ instances. It represents what
        they share in common which is essentially being a physical kind
        of thing and being the kind of thing made by humans. It is also
        stated by the ontology that this then is from where you can
        begin to speak of representations. According to crm
        representations are only made by humans.

        So if you need to talk about things that are movable you hop
        down to e22 and if you are needing to make statements about
        things that are features hop down to e25.

        E24 is a class that likely isn’t invoked much directly but
        rather serves to support the representation of some things that
        are common in its child classes.

        Linked.art takes the decision to not split the hairs about
        whether a thing can be moved or not (since ultimately anything
        likely could be moved with a little imagination) and uses e22.
        But for some e25 serves useful purposes for indicating the
        physical objects that inhere in other objects.

        Is that helpful or addressing the direction of your question or
        did you have something else in mind?

        Best

        George

            Dear SIG,

            The scope note for E24 says,

            "This class comprises all persistent physical items of any
            size that are purposely created by human activity. This
            class comprises, besides others, *human-made objects, such
            as a sword*, and human-made features, such as rock art. For
            example, a “cup and ring” carving on bedrockis regarded as
            an instance of E24 Physical Human-Made Thing."

            Is this right/misleading?

            If it includes objects then why can't they be moved? The
            note includes items that might be considered objects - they
            are usually defined in E22 or E18  -  items which have
            "physical boundaries that separate them completely in an
            objective way from other objects."  This explains the
            difference between a carving on a wall and a movable object.
            If the carving is cut out of the wall then it gets sound
            physical boundaries and can be moved.

            Cheers,

            Dominic
