"Be conservative in what you do; be liberal in what you accept from
Absolutely - completely agree.
UKOLN is taking forward the development of the harvesting and
aggregation service which underpins the Intute Repository Search. We
are developing what I call a 'heterogeneous metadata store', which
while using OAI-PMH and OAI-DC as it's default harvesting mechanism/
standard, will not demand further quality assurance or compliance form
source-repositories. Our philosophy is that we'll take whatever we can
get, and then we'll process what we have for particular services,
according to their needs. If a service has a requirement for a
stricter compliance with some norm or standard, then we can filter for
them accordingly. This is, in fact, the approach we already take for
the Search service, while delivering a differently filtered set of
data to other projects/services.
We will be investigating the harvesting of other metadata formats,
possibly using other mechanisms. Currently our baseline requirements
- we only harvest and aggregate metadata records in well-formed XML
- we only harvest from repositories listed in OpenDOAR (we use
OpenDOAR as a service component)
- we only harvest 'open access' records.
err - that's it!
This is likely to remain the case for the foreseeable future, although
we're working this out now.
