thanks to the links provided I could easily consult

< https://en.wikipedia.org/wiki/Avatar_Studios >

and < https://en.wikipedia.org/wiki/Like_a_Virgin >

Thus: It was the exact building in Manhattan, although the name of the studio
at the time of production was "The Power Station".

It can be expected in the long run that wikidata or dbpedia or whoever
will state the "variant" names and the corresponding dates (the name change
occurred in May 1996 according to the wikipedia article (July 1996 according
to the studio's home page, however they refer to "open[ing] its doors") i.e.
the information is already there but still has to be converted from "text"
into "data").

It will be the responsibility of every data provider to decide whether
"Avatar Studios" is a firm (and "The power plant" was another firm, mandating
two entities) or a building housing renowned individual recording studios
(rooms). As we all know, reality is slightly more complex than these two
options, obviously the studios (firm) is responsible for keeping the studios
(facilities in the building) up to their standards...

Now, the librarians responsibility is to keep the libraries records up to
standard. Others already have stressed that the focus is shifting from
giving perfect /descriptions/ to reliably providing /relations/. This can
only be based on "Authority Control" which - properly understood - does
/not/ consist of bricolaging "headings" disambiguating at text level but
in performing intellectually sound identifications and discriminations
which then are recorded. In consequence this means authority records which
/represent/ their corresponding entities even when they are still uncomplete,
authority records which can serve as accretion points for /data/ and
not just are a bag for collecting "variant forms", *and* stable relations
between bib records and authority records, i.e. proper linking obliviating
the practice of being forced to match and re-match strings ever and ever.

Personally I see a continuing (if not eternal) demand for a profession
performing identifications as above: Any bookseller, publisher, record label
or IP agency may have an absolutely consistent (and sometimes even public)
database of the objects important for their operation, but it is the
librarians main task to make the connections when these objects (books,
authors, ...) or evidence of them are found in the wild...

The standards of library records and of librarian's professional authority
would be watered down if "information found on the internet" would be
blindly /incorporated/ into library records, be it by automated techniques
like "inference" or good old "copy & paste": Sometimes the source would not
be reliable enough, in other cases it may evolve too rapidly and leave
the libraries records with incomplete or outdated information. Shifting
information from bib records to authority records already constitutes a
certain kind of "decoupling" which seems necessary here.

Assuming that information literacy is not only a lip service, the librarians'
professional task then is assessing and selecting those external sources
which should be ~connected~ to their services (most prominently the
catalogue). This connection may express itself by merely providing links
in the OPAC, inserting content by mashups, indexing harvested metadata
or even indexing full texts or original art. Certainly there are technical
economic and legal impediments and in most cases one will not be able
to implement an additional service just because it can be thought of. But
to my impression big ILS companies have long since begun to invest into
content databases which then at a calculaded cost and with less technical
hassle be licensed and accessed by users of appropriate ILSes...

As for the initial examples: No, we probably will never investigate the
history of the recording studios when some madonna album enters our
stacks. And our "agent" definitely is the studios-as-a-firm and not the
studios-as-a-facility. But a closer look at our resources could show
that they allow differentiation between "place of operation" (of the
pruduction company: Manhattan) and "place of recording" (the physical
studios: Manhattan) and the records we produce shouldn't mess this up.
And that (collaboratively!) subduing these kinds of entities under
"Authority Control" is worth the effort. /Other/ communities will build
up more detailed data (wrt individual tracks, or which facilities have
been when operated by what company, all individual producers or sound
engineers involved &c..., of course geolocation information for whatever
can be tagged with coordinates) and the requirement for library data
is to be able to connect with that as soon as librarians assess this
as "reliable".

So, actually we are not talking "bibframe" here but about organizing
librarians work (more "authority control" would be a start) and organizing
librarians work: the output is not some static "record" enduring until
the end of civilization but must be adapted to reliably record the outcome
of the processes *actually* performed by the librarian, not more and
most eminently not less: I claim that most of the many, highly intellectual
identification processes performed by librarians never make their way
into library data. This is a shame (we *are* better than that) and a
waste (since it is not recorded the next person is forced to do the
same work again).

It takes people power (time/money) to fill in data fields/codes using human expertise and judgment.  Links and inferences  can be misleading and outright wrong.   (I remember a few instances when catalog records were 'mutilated' by bad authority control links, such as the time Madonna (rock singer) was substituted for the Virgin Mary.  Wrong inference!)

In the early days it wasn't always seen as critically important by some folks either because it sometimes duplicated what was already stated in the 'important part' of the record, or time and work quotas didn't allow that level of detail, etc.  And some would ignore its importance if it didn't affect what printed on the cards—not thinking about the possibilities that computer applications might bring (for better or worse) in the future.  And the fact that it is next to impossible to get ILS vendors to incorporate the use of so much potentially helpful data in our MARC records certainly played a role in which data was viewed as important or unimportant.  One thing I know for sure:  no matter what the framework, the usefulness of a catalog record is only as good and complete as the human thought and effort that went into its creation; and attempts to change or expand upon that through ext
raneous means should be viewed with a critical eye.

And since this is the design from the start, it's not shoehorning onto a data format that isn't particularly well suited for it.
