"Be conservative in what you do; be liberal in what you accept from  
others".

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  
are:

  - 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.
