SRU access to the Aquifer Portal is up and ready for testing. explain and searchRetrieve are working. Basic error are caught and returned in a diagnostics element. The base address of the service is http://www.dlfaquifer.org/sru Please test, and test.
I shook it down with some help from Ralph LeVan and an SRU test website he created (http://alcme.oclc.org/srw/SRUServerTester.html). Our service now passes most of the tests, we are failing a couple that have to do with error conditions, that I have not quite figured out how to detect. Instead we just return zero hits.
The explain packet does not list all the potential indices yet, but I am holding off on that while Tom and I look into a more generic approach to the MODS SOLR interaction.
