Hi,
Nice question! I think it would be natural to consider 'Archivist' a
profession, and thus RiC-A30 ('OccupationType') is very relevant.
Indeed the documentation for OccupationType in both RiC-CM and RiC-O
has some clarifications that relate directly to this.
https://www.ica.org/standards/RiC/RiC-O_v0-2.html#OccupationType
In short, one would I think consider 'Archivist' to be an entity in
the 'Value schema' of RiC-A30. More formally, in the ontology, one
would consider 'Archivist' an individual of class OccupationType (and
one might also make the individual have the type of some ontology of
professions outside of RiC). And then one can say that a Person has
the OccupationType 'Archivist'. To avoid confusion later, let me refer
to this occupation type as 'ArchivistOccupationType' rather than just
'Archivist'.
As for 'archivists' (plural), one could consider this to be the people
with occupation type Archivist. In the ontology, one can express this
formally (we use the singular by convention, i.e. defining the concept
Archivist which defines archivists):
Class Archivist:
SubClassOf: hasOccupationType value ArchivistOccupationType
(As an aside, RiC-CM also has RiC-A15 'Demographic Group'. In the
ontology, OccupationType is defined to be a sub-class of
DemographicGroup. This means that the OccupationType
'ArchivistOccupationType' is also to be considered to define a
DemographicGroup: one is not supposed to distinguish between
'Archivists' and 'Archivist' by saying that the former is a
DemographicGroup and the latter is an OccupationType, rather 'has
occupation type: ArchivistOccupationType' is just a more specific way
of saying 'belongs to demographic group: ArchivistOccupationType'.)
If we wish to assemble archivists into a RiC-E09 group, as I think is
reasonable (one can certainly think of all the archivists belonging to
a particular institution, say, as carrying out a 'coordinated
activity'), one would introduce an individual 'Archivists' of type
'Group', and make the notion of archivist as I defined it (individual
of type Archivist) more precise, by saying that an archivist is also a
member of this group:
Individual: Archivists
Type: Group
Class Archivist:
SubClassOf:
hasOccupationType value ArchivistOccupationType,
isOrWasMemberOf value Archivists.
When it comes to Position, in fact, in the ontology, Position is
formally disjoint from Person (and also from Group); one is only
supposed to relate a Position to a person, e.g. by RiC-R054 ('occupies
or occupied'). This disjointness formally expresses that a position
('head archivist' or whatever) is fundamentally independent of
whichever person holds it and of the entity at which it is carried
out. If one wished to express that 'head archivist' at Institution A
is a position that only be filled by archivists as I defined them
above, one thinks of this as defining a sub-relation of 'occupies or
occupied' with domain restricted to Archivist, i.e.
Class: ArchivalPosition
SubClassOf: Position
ObjectProperty: occupiesArchivalRole
SubPropertyOf: occupiesOrOccupied
Domain: Archivist
Range: ArchivalPosition
and then 'HeadArchivist' would be an individual of type 'ArchivalPosition'.
One can also consider 'archivist' to be a position at some institution
or company: to express this, one would introduce an individual, say
'ArchivistPosition', of type 'Position' or of my more specific
'ArchivalPosition', and link it using e.g. RiC-R056 ('exists or
existed in') to the relevant institution/company.
One of the things that one hopes for in the future are canonical
taxonomies/vocabularies for things like occupation types, so it may
well be that the individual 'ArchivistOccupationType' above will in
the future be able to be fetched from such a taxonomy rather than
having to define it oneself, and perhaps the kind of mechanics using
this individual that I have suggested above will too will simply be
able to fetched rather than having to be defined oneself.
I hope that this was somewhat helpful; as ever, this is just how I
read it, and if I have written anything egregious, I hope that people
will not hesitate to correct it!
Best wishes,
Richard
