I may be wrong, but... couldn’t an instance have a SeriesTitle (a not yet defined bf:Title subclass), that allows for recording both the transcribed series title/statement in an rdfs:label and title parts through MainTitles, Subtitles, PartNumbers? Using logic from title proposal I submitted on July 23rd, and the creation of a bf:SeriesTitle subclass of bf:Title, one seemingly could handle both Titles for the Series entity and transcribed Series Titles on the bf:Instance.

That's exactly what I am saying. That related things that are specific 
to that instance, not global or universal, get blank nodes. Related 
things that have an existence outside of that instance, such a series, 
need to have URIs. In programming, this would be the difference between 
local variables, that only have an identity that is true within that 
specific context, and global variables, that have an identity that can 
be used anywhere. In RDF, *everything* is a graph, even a single triple, 
so "graph-ness" isn't what is significant here, it's the scope of the 
identifier that makes the difference.

I'm assuming that transcribed information would be attributes of the 
instance, since they are about the instance. The question then becomes 
whether it is necessary to link the transcribed series title to the 
series entity. As I understand it, the transcribed series title would 
help someone identify the instance ("it's the one that spelled "journal" 
as "juornal"). The instance would also have a link to the series URI. We 
should think carefully about use cases - machine actions that could not 
be performed if the two are not linked.

> You wouldn’t want an Instance level bf:SeriesTitle like “The 13th Installment of the Mysteries of Data Modeling (with RDF)” reused on the bf:Series “The Mysteries of Data Modeling”. Also, if you had a bf:SeriesTitle that was linked to both a Series and an Instance you couldn’t subtype the Instance title, e.g you couldn’t say <ex:Title1> was also a <bf:RunningTitle> without saying <ex:Title1> is always a bf:RunningTitle. That may not be true for other Instances of the Series.

You'll need to distinguish preferred labels and alternate labels and 
transcribed labels with more than a class. A series should have a 
preferred label (authoritative form of the name) and, if necessary, 
alternate labels. (The SKOS use of labels may not be sufficient for 
cataloging purposes, and alternate labels may need to have 
subproperties.) I don't see a reason to have

<ex:Title1> a <bf:SeriesTitle>

A preferred display form in the series graph provides that. I think this 
form comes out of thinking that the series information will be recorded 
in the instance graph not the series graph. This is a habit that comes 
from "unit cataloging" before linking was possible. If true linking had 
been implemented between authority records and bibliographic records, 
then I suspect that we would have discontinued the re-entry of strings 
in the catalog records, since those would have come from links. So try 
to see the catalog record as having links in the place of headings. That 
should work because headings were intended to have a role as identifiers 
-- they just didn't work well for that because they also had a role for 
display and displays sometimes have to change (whereas identifiers 
cannot without becoming a different thing).
