RDF is not only about sharing but also about information integration.
I found the support of NCIP in integrated library systems somehow
disappointing and report of the Digital Library Federation more like
a lip service. The chance of someone writing a Linked Data seems
more likely than someone writing an NCIP wrapper, as RDF is much 
more common than library-specific formats. In addition, mapping
one part of your library system to RDF helps you to map the rest.

I had only aggregation on a smaller scale in mind: a user (or a user's
client) would aggregate patron data from different libraries, for
to show a combined list of his loans. For this reason I was looking for
a simple ontology to express the most relevant library patron data in 
RDF. I guess that user account information can be expressed with SIOC
and FOAF, but some specific properties such as 

- due-date
- number-of-renewals
- sum-of-dues

would be needed. I hesitate to create yet another library-specific
ontology (in addition to DAIA/RDF) and I wonder why no integrated
library system has started to use RDF. Maybe hacking it into Koha
is a good strategy, as I do not expect any commercial vendor to do so.
