The problem might be clearer by asking what the subject and object of bf:hasHoldingOrganization statement are in this example. 

The subject is apparently a blank node bf:Organization and the object is something with "organizations/dlc" as an identifier. That's odd. Presumably the item (which IS identified) should be the subject instead of the blank node.

I agree that the concept of "Authority" shouldn't be dragged into this particular example. Statements involving the bf:hasHoldingOrganization property should be understandable without it.

The example is:

 

           bf:heldBy    [

                     a                                               bf:Organization ;

                     rdfs:label                                “DLC”   ;

                     bf:hasHoldingOrganization        <http://id.loc.gov/vocabulary/organizations/dlc> .  ]  ;

 



trying this out as triples, because that's where the proof of the pudding always is:

X bf:heldBy _:b1 .     //the subject X is held some by thing identified by _:b1 .
_:b1 a bf:Organization .     //_:b1 is of type "Organization" .
_:b1 rdfs:label "DLC" .     //the display label for _:b1 is "DLC"
_:b1 bf:hasHoldingOrganization <http://id.loc.gov/vocabulary/organizations/dlc> .     //_:b1, which is of type Organization, hasHoldingOrganization <http://id.loc.gov/vocabulary/organizations/dlc>.

Putting this again in words:

Some thing (X) is held by some other thing (_:b1). The thing _:b1 is an organization as defined by BIBFRAME. The display label for the organization is "DLC". The organization "_:b1" has a holding organization with an LOC IRI.

This is what Jeff said, I just find it easier to see it when triple-ized. If the domain of bf:hasHoldingOrganization is bf:Item, then this has declared the bf:Organization "_:b1" to also be an item. In any case, it makes no sense that the organization has a holding organization. It looks like the correct set of triples would be more like:

X bf:heldBy _:b1 .
_:b1 a bf:Organization .
_:b1 rdfs:label "DLC" .
X bf:hasHoldingOrganization <http://id.loc.gov/vocabulary/organizations/dlc> .

Leaving us, of course, still with the question of organizations vs. authorities for organizations.
