OAI-PMH Pagination/Resumption Token

Omeka Classic Plugins
1

I’ve been using OAI-PMH plugin to harvest small collections with fewer than 100 items, which has been really great. However, I’m working on my first collection with more than 100 items and am wondering how pagination works. I harvested the first 100 items from the repo below, but am unsure how to get the remaining items.

http://engagedscholarship.csuohio.edu/do/oai/?verb=ListRecords&metadataPrefix=qualified-dublin-core&set=publication:crohc999

I tried manually setting the resumption token parameter, like so (resuming at 100 and stopping at 110), but that didn’t work:

http://engagedscholarship.csuohio.edu/do/oai/?verb=ListRecords&metadataPrefix=qualified-dublin-core&set=publication:crohc999&resumptionToken=100,110

Here’s my status log for the initial harvest (disregard the first import/delete at 2017-04-25 13:47:43):

The harvester doesn’t expect you to be putting parts of the OAI request into the URL you give it. The base URL for this repository should just be “http://engagedscholarship.csuohio.edu/do/oai/”

Most repositories would have given you an error well before you got to this stage.

Ah, not sure when or why I started doing it that way, but if there was ever a reason, it no longer applies (I’d had some issues troubleshooting the source repo in the past). That worked just fine, thanks!
