I'm happy to go for the Google format, I just thought that our
commitment to standards would tip the balance towards OAI. Does OAI
not allow for a minimal form like Googles'?


Good point. However, I don't think OAI has a "minimal" form, I did some preliminary research into it a few months ago. Let me check it out, I'll report back.

OK, I've rechecked the schema and the OAI-PMH schema requires that a date be provided in headers for each record (which coresponds to a documet in our case). This means we need the last modified date otherwise our data will be inaccurate, that is using last-published will make harvesters think that the file was modified on that date.

see http://www.openarchives.org/OAI/2.0/openarchivesprotocol.htm#OAIPMHschema

Furthermore, as I mentioned in a previous mail, OAI is not about indexing documents (like the Google sitemap) it is about indexing meta-data. To use OAI-PMH for anything worthwdile requires quite a bit of additional functionality like complete meta-data etc. I *do* want to see this included but do not believe it is appropriate to the vast majority of our present users.

I think we should proceed with the simpler case of Google and return to OAI wen we have a meta-data system in place.
