“Not sure something that narrow is needed.”

Well yes, it’s needed, but you’re right, within the main spec, that is, in the oa: namespace,  “attaching cover art” is probably too narrow.  “attaching” (or “attachment” or “attach” or whatever form we end up with)  would be appropriate as a motivation, within oa:, and then an external namespace (e.g. BIBFRAME) could define “attaching cover art” as a sub motivation, or as Jacob suggests, a narrower concept.

Not sure something that narrow is needed.

There is also an "oa:linking" already, fwiw:
"The motivation that represents an untyped link to a resource related to the Target."

My guess is that you'd further describe (perhaps in your own vocabulary) that the resource related to the target is indeed cover art (vs. the inside flap, spine, etc).

So “attaching’” would be a motivation, and “attaching cover art” a sub-motivation?    How do you express a sub-motivation?

My first intuition with regards to changing the predicate to "asserting" is that it is probably okay. However...

With regards to the Bibframe use case, I understand it from bygone days as a cataloger. It is frequently the case that it is desirable to give OPAC users additional information about bibliographic resources beyond the metadata records that describe them and, it certainly became standard practice in the early 2000's to attach cover art images to metadata records as a means to supplement them. When the end user retrieves the record in the OPAC it gives them something to look for on the shelf.

In this example though the actual motivation for the annotation is not "Cover Art" but rather "Attaching a Resource" -- in this case an image file depicting some cover art. Bibframe has a specific use for a more general motivation within their contextual framework. In this case I would make a Skos concept for "attaching" or "linking" and then make an additional concept for "attaching-cover-art" which is a sub-type of the first concept.

No real need to wander away from using verbs in the gerund form.

(As Rob notes, it's actually "motivatedBy".)  I would like to change it to "asserting".  I think of an annotation as asserting a relationship between the body and target.  Thus, if A is a review of B, then the annotation:

•         has target B,

•         has body A,

•         is asserting that  the body is a review of the target.  I.e. it is “asserting (a) review”

I'm trying to find a middle ground here, where we can talk about type without it needing to be rdf:type.

I lied.

Well not really lied, but perhaps we could  see this as a change where the world at large would view it as cosmetic while my constituency would see it as something more substantive.

I want to also point out, although  the motivations listed in the model are expressible in the gerund for (and perhaps all could be expressed in infinitive form)   there are going to be annotation “types” that cannot be expressed in either of those forms.  I have already submitted “cover art” as an annotation type.  How would you express the motivation there? “Coverarting”?  “Table of contents” is going to be an annotation type in BIBFRAME (which I’ll explain in a separate post) and that’s another example.  HeldItem might be another annotation type.

In responds to Rob’s questions:

> * Is the objection to the use of skos:Concepts, rather than classes?

No, no objection from me, to the model prescribing this approach.  We have already left the door open for other namespaces to use subclassing instead (or in addition) and that’s good enough for me.

The closest thing I see (in the model) to a definition is “the reasons why the Annotation was created”  and I have no objection to that definition.

No, to say that there would be a significant improvement in understanding would be a stretch. I am saying that the suggested change would allow those of us who like to think in terms of annotation types to do so, without forcing the concept on those who don’t.
