Interoperability
•We all know our own back yard (“We all know
what we mean”)
•Q: Why
do we want persistent identifiers?
•A:
For interoperability
•“persistence is interoperability with the
future”
•We know what we mean, but others may
not.
–Identifiers assigned in one context may be encountered,
and may be
re-used, in another place (or time) -
without consulting the assigner. You can’t assume that your
assumptions will be known to someone else. Interoperability = the possibility of use
in services outside the direct control of the issuing assigner
•Interoperability therefore implies extensibility
•Hence our work on ontologies etc
