Hi Ann,
Thank you very much for writing and sharing this, I love it! A beautiful
example of defining a 'meta-model' for a RiC description of a collection;
not too many examples of this kind of thing have been shared on the list
before I think, it's great that you did so!
I am impressed with the modelling, which is both accurate (at least
according to my own interpretations!) and detailed: a large proportion of
RiC is involved, including almost all entities. I will make a few minor
comments below, but these are of no great significance, what you have is
already really good.
I too love Matthew's tool! I have written to Matthew privately that I and
others in EGAD had something like this in mind for some time, indeed I was
intending one day to try to make something like it; but it would not have
been as good as what Matthew' has created, it is fantastic and better that
it has emerged out of the RiC community instead!
My not very important comments on the modelling:
1. Where you have written 'Or Activity? That Record Set records' (n37,
towards the right), I would suggest indeed to use Activity here, and to use
'documents' instead of 'results or resulted from' in the arrow from n27 to
n36. There are a few words about Event vs Activity in RiC-AG at the
following link (§6a.3.3; the previous section §6a.3.2 may also be useful)...
https://ica-egad.github.io/RiC-AG/faq--general_questions_and_smaller_modelling_questions.html#can-you-elaborate-upon-the-difference-between-activity-and-event
...I'm not sure if that helps much, but a reasonable rule of thumb would be
that Activity (and 'documents'/'documented by') is almost always correct
when it comes to the raison d'être of a record resource, i.e. what it is
about/documenting. What you have is not wrong, since Activity is a
sub-entity of Event and 'documents' is a sub-relation of 'results or
resulted from', but expressing it more precisely where one can is always
good!
2. On the other hand, in n29 'Or Activity? How we come to have it', here I
think I'd be inclined to keep n28 as Event in a meta-model of the kind you
are describing, just mentioning that Activity can be used where
appropriate. I'd imagine that there could be a fair bit of serendipity
sometimes in 'How we come to have it', i.e. the 'agent-designed and
performed' aspect of Activity that RiC-AG refers to would be unlikely to be
regarded as present (or at least rather a stretch!).
3. Whereas for 'n5', I'd definitely view accumulation of the collection as
a whole as an Activity: there is definitely some
agent-performed/designed-ness there :-). For the same reason, Activity and
Activity Type seem good to me in n13 and n14.
4. I very much enjoyed the use of 'results or resulted from' between Family
and Event (n50 and n52)!! I had never thought of that before!! To be a
killjoy, some might think that this might be stretching 'results or
resulted from' a bit far, perhaps the weaker 'is associated with event'
could be used instead if so :-).
5. In relating Record Parts to Records, and Records to Record Sets, I'd
suggest to use the more specific 'has or had constituent' and 'includes or
included' respectively; again, not wrong how you have it, but more specific
is good :-).
6. I think 'has or had part' is not really intended to be used with Person
as domain, at least an example would have to be quite out-of-the-way I
think, as it is supposed to refer specifically to parts-of-a-whole. I think
Position is not really intended for roles in the sense you have in mind
either; I think probably it can be used with Family in some circumstances,
e.g. 'Father-figure', but then it is something 'fixed', whereas if I
understand correctly you mean rather the role a family member might have
played in a given Event/Activity. I think what I would suggest here is to
add a second path between Person and Activity which is interpolated by
another Activity of type 'Role that a person played in the Event/Activity',
using the relations 'performs or performed' followed by 'is or was subevent
of'. I.e. one ends up with a triangle in which the short way round is the
arrow 'is or was participant in' that you already have, and the long way
round consists of 'performs or performed' (with range Activity) followed by
'is or was subevent of'.
That's all I think!
As an aside, I am quite interested in exploring interactions between RiC
and conservation; I have a friend who works in conservation at the London
Archives, and there are a few themes we're interested in exploring. In case
you would be interested in that, do let me know :-).
Thank you very much again for sharing this very nice modelling!
Best wishes,
Richard
