The doc for the OAI-PMH API explains that the “specs” (set id) for the sets corresponding to each journal are composed like this:
J:10.{publisher id}:{internal journal id}
The publisher id is the same that is found as part of publisher-issued DOIs for publications.
It happens that journals change publishers. I’m wondering what that does to the OAI set specs since those are publisher-specific. It looks to me like this results in the ListSets verb giving different specs over time. For example, I previously found:
Studia Psychologica → J:10.21909:302382
But I now find this:
Studia Psychologica → J:10.31577:302382
My main question is, will retrieving the most recently listed spec include the items previously included under the old spec? If not, how can I retrieve ALL the specs for a journal? As far as I can tell ListSets returns one spec per journal id.
thanks!
