There are two issues with OAI-PMH on a multi-journal (one domain / journal, multi-language) installation with DC export:
For the central, platform OAI-PMH URL, the DC export of an article misses the DOI in the dc:identifier for each journal, although the DOI had been assigned. Example:
On the journal OAI-PMH URL, the DOI is visible. Example:
Is this intended behavior? I don’t think so.
We would prefer to provide the central platform OAI-PMH - harvesters then can harvest all the journals via the sets and we wouldn’t have to register each journal url with the harvester. Therefore, dc:identifier with DOI must be available.
In a multi-language setup, the dc:source element is repeated for each language, see journal URL above.
This might provide harvesters problems. We propose that only dc:source is exported, for the main language.
