My silence is general agreement, although there are perhaps different ways of
categorising the FR users tasks/needs within the dimensions. But I don't think
that would make much practical difference, and the current taxonomy is fit for
purpose.
 
Karen (post-this) is right to say that the FR models are somewhat siloed,
although it should be pointed out that they have, over time, taken into account
the museum (e.g. FRBRoo) and archive (e.g. FRAD) communities. I think there may
be two main causes for any silos, which this group should bear in mind:
 
1. The classic Libraryland environment begins with the FRBR Manifestation, a
finished product of the publishing industry (or manuscript). It is only recently
that pre-manifestation metadata has become important - publisher metadata can be
copied and recast to save cataloguer time, but this has only become generally
feasible as a result of initiatives such as ONIX, the RDA/ONIX Framework, and,
indeed, the linked-data movement. The FR family is also focussed on user tasks
which consume metadata; the generation and maintenance of metadata by users,
professionals, or machines has been out-of-scope (the FRAD stuff about agencies,
rules, and controlled access points might spill over, but the focus is on how
these affect the metadata content).
 
2. Libraries operate in the real-world. They have customers (lots of them) with
expectations (changing, of course, but mostly legacy); they are funded by real
organisations and real money (never enough). The funders have their own
expectations. As a result, libraries tend to be conservative. They also tend to
be cautious, having been burned on numerous occasions in the past by "new
technology" (but they know that such technology is their saviour). It's messy,
illogical, and, in the UK at least, gets consistently high approval ratings by
customers (the public taxpayers). Needless to say, these factors vary from
country to country and culture to culture - so IFLA and other
national/international library collaboration on standards and models is,
relatively-speaking, outstanding and as good-as-it-gets.
 
Something missing from the Dimensions is any hint of institutional repositories
(and therefore Dublin Core); these are within scope, as, in the UK at least,
their metadata is often maintained or quality-controlled by libraries.
 
Cheers
