OAI harvest and PORSCHE: Testing intraLibrary 3.5

December 15, 2011 1 comment

Quick recap: a requirement of PORSCHE was to transfer metadata between Jorum and the NHS eLearning repository:

The primary aim of the PORSCHE project is to provide “seamless access to academic and clinical learning resources to healthcare students”… “establishing the basis for a long term national partnership between the NHS and academia by sharing of appropriately licensed content between Jorum and the NeLR”.  To achieve this, PORSCHE has been exploring metadata transfer between the two repositories using OAI-PMH. Jorum is currently running on a modified DSpace (v1.5.2) and the NeLR on intraLibrary (3.1) both of which will of course expose an OAI-PMH feed, however, there would be an additional requirement for each repository to ingest each other’s feeds which is functionality that is not currently supported by either platform, though it is supported by the NDLR running on a later version of DSpace (v1.6) while PORSCHE are currently liaising with Intrallect to develop similar functionality in intraLibrary.

Along with the PORSCHE team I’ve recently been testing a pre-release intraLibrary 3.5 which now includes an OAI-PMH harvest facility so that the metadata from external repositories can appear as a “collection” in intraLibrary. In the context of our own ACErep project, for example, this would also allow us to harvest the ALPS collections from the repositories at the University of Leeds and York St John, thereby offering a form of federated searching as collections are all brought under the standard intraLibrary search mechanism.

harvest admin

Harvest admin allows multiple harvests to be set up with the relevant oai url; user selects the desired collection (oai set) from the drop-down.

Selecting the OER collection from the Leeds Met repository (corresponds to OAI set=23) I am able to select harvested metadata format (dc or lom) and type of harvest (All Records, Since Last Success, From Date), time to run, and select intraLibrary Group/Process and Collection:

Bingo!

Bingo!

Bingo!

…and then, crucially for ACErep, I’m able to search my harvested collection (called mrnick) by SRU:

http://harvest.intralibrary.com/IntraLibrary-SRU?recordSchema=lom&operation=searchRetrieve&version=1.1&maximumRecords=10&startRecord=1&query=rec.collectionIdentifier=mrnick

Not sure yet when we’ll be able to get intraLibrary 3.5 but it should then be straightforward to harvest ALPS collections from the University of Leeds and York St John and search all ALPS resources across the three institutions from an ALPS branded interface.

In the context of PORSCHE, when the NHS is running 3.5 they will be able to harvest relevant collections from Jorum (e.g. HE – Medicine and Dentistry) into the NeLR.

Work to achieve similar from Jorum is ongoing via liaison with PORSCHE – see also my post on the UKCoRR blog at http://ukcorr.blogspot.com/2011/12/jorum-steering-group.html and this recent post on the Jorum blog on Coming improvements to the Jorum UserExperience
