Hello Michael, Nicholas et list,
Hi Michael
I hope you don't mind me jumping in here with a few comments on selected
highlights of this thread.
>> Taking /music as an example...
I wonder if you have looked at book data? I am working on issues to do with
linked (open?) book data and it would be useful to compare notes.
Not much. We've played around with ideas about linking programmes to books
(readings, reviews, dramatisations etc) and played with some book data.
Mostly it seems to make music metadata look sane and tidy :-/
>> wikipedia tends to conflate...
composition with recording with release...
On the other hand, data does exist that separates these (and more!) entity
types out very clearly, and it's potentially highly *linked* but it's unlikely
to be *open*. See:
http://www.ddex.net/ddex-present - ddex descriptive data schemas, but also
note the links there to IDs for
-names (ISNI)
-compositions (ISWC)
-recordings (ISRC)
-releases (GRid)
These are all industry-standard IDs, and thus pretty stable. Maybe a starting
point?
We have some industry identifiers internally and MusicBrainz has some
coverage of ISRCs. But they're all really just identity authorities. They
don't really deal with the links between entities which is what things like
MusicBrainz give us
>> ...domains where there's no
established (open) authority (eg the equivalent

EIDR?
http://eidr.org/ - " EIDR is operated on a non-profit cost-recovery
basis..." but maybe you get the stability and granularity you pay for? Plus;
"... EIDR is founded on the principle of open participation and welcomes all
ecosystem players (commercial and non-profit) to join the Registry as
registrant, lookup user or even a promoter. The Registry is intended to
provide a foundational namespace for A/V objects that can be leveraged by
participant in the eco-system to further their own business needs and
offerings." -

Same story with eidr really. They're an identity authority rather than a
metadata service. They take just enough metadata to be able to effectively
spot duplicates. Which is handy but isn't linked data
(personal opinion is) one day all identifier schemes become http uris
because identifiers which link and can be dereferenced are more useful....
