I'm working on a repository introspection service that provides a repository
profile from the point of view of cmodels and services. The motivation is to
obtain a concise picture of what's in the repository, provide export tools to
aid in selective migration, and to generate model/service documentation from
the models and services themselves.
My question is this: Is there a way, using Fedora REST APIs or triple store
queries to obtain a list of the pids of cmodel objects in the repository?
I'm currently using the triple store to query for cmodel / service pairings:
select $cmodel $service
from <#ri>
where $cmodel <fedora-model:hasService> $service
But that will only find cmodels that have associated services. Ours tend to
fall into that category but I'd like to do it in a way that is more general.
I'm not very experienced with using the tripe store, so I'm hoping there's a
way there to do this, though that seems doubtful from what I'm seeing in cmodel
RELS-EXT.
I know I can do a sql query on the database ( select distinct cModel from
modelDeploymentMap) , but I'd of course like to avoid cutting in at that level,
and I'm not sure cmodels without services are represented there anyway.
Is there a way to discover cmodels using the APIs or the triple store? Or is it
best to put something specific in cmodel RELS-EXT for that purpose? That's what
I'm about to do, but thought I'd ask first.
Thanks,
Bill
