[ckan-dev] OAI-PMH Data Provider

Mon May 29 12:48:03 UTC 2017

Dear Tom and Juho

Thanks, I am certainly willing to collaborate, especially to improve the package-converter.

I implemented from scratch my own OAI-PMH repository because we had quite some specific needs in addition to time/resources limitation (https://github.com/EnviDat/ckanext-oaipmh_repository).
For example a custom metadata schema and the fact that we use it to register DOIs so we have to keep some "security index" with read-only access because if the CKAN get's hacked it can really create a mess.
I addition we will have DOIs at resource level (instead package), so the OAI-PMH  records may be packages and resources. I am still thinking how to implement this, I guess I need to start from the converter.

Best,
Lucia

FYI note that using ckanext-spatial extension leverages pycsw which provides
CSW, OAI-PMH, SRU, and OpenSearch support.

Hope this helps.
