> The OAI-PMH interface supports a number of different formats, via the 'metadataPrefix' parameter. The supported formats can are listed by the OAI-PMH interface e.g.:
> http://example.com/cgi/oai2?verb=ListMetadataFormats (change for your own domain).
> You may want to check other metadata formats include all the information you want too.
>
> The formats all use an Export plugin, which live in:
> ~/perl_lib/EPrints/Plugin/Export/ (default EPrints export formats)
> ~/lib/plugins/EPrints/Plugin/Export/ (added by Bazaar packages)
> ~archives/ARCHIVEID/cfg/plugins/EPrints/Plugin/Export/ (local plugins for this archive).
>
> Taking the OAI_DC metadata profile as an example (~/perl_lib/EPrints/Plugin/Export/OAI_DC.pm), this calls the normal 'DC' export plugin, but formats the response for OAI-PMH.
>
> So, to include the identifiers you asked for, you need to change the DC export plugin.

> The DC plugin is also used to add metadata to the <head> section of eprint summary pages.
> Changing the plugin in this way will change this too. In this case, you probably would want the same changes.
> If you wanted to add something to *only* the OAI-PMH DC representation, you would need to subclass the OAI_DC export format, and make changes in there instead.

> Hope that isn't too confusing - let me know how you get on!

> PS The 'incorrect' way to do this is to just hack ~/perl_lib/EPrints/Plugin/Export/DC.pm. If you do this, when you upgrade EPrints, your changes will be lost. If you do it the right way, your changes are retained - but you may need to update them.
