Hi all,

Some comments and questions regarding the Use Case Template [1].

First a very general comment : it is not really clear to me if we're
looking for use cases scenarios (services that we imagine could be
created), or use cases that provide a feedback on actual
implentations, projects, etc. that are undertaken in libraries. In the
charter, it looks like the latter was intended.
What I understood from last telecon was that in the Provenance group,
the use cases were more theoretical, and were consolidated in a few
In the SWEO use cases [2], it is rather about describing an existing
In the end, I think both ways are interesting, but I would be in favor
of a specific section in the template to express if the use-case was
implemented, by whom, and what was the outcome  : was it successful,
or not, and why.

Small comment on the introduction of the template :
"It should not be confused with specifying the technology itself: a
use case may allow for many alternatives to achieving user needs."
I wonder if really fits our goals : we want use cases that show how
Linked data can help libraries achieve their tasks, not generic use
cases for library tasks.
Here again, I think our focus is different from Provenance XG. For
them, Linked Data is the context, and provenance data is the goal. For
us, library data is the context, and Linked Data is the goal. Quite
the opposite ;-)

Regarding dimensions : related to my previous comments, I think we
need to define library dimensions rather than Linked data dimensions.
for instance I would suggest dimensions such as :
- library catalogues for users :
-- bibliographic data
-- thesauri, authorities
-- collaborative data (reviews, comments, tags)
- library data exchanges (between libraries, B2B)
- management data
-- user logs or usage data
-- loan information
-- administrative & preservation metadata
These are just a few ideas as a starting point.
