Dear Colleagues, There is a digital repository indexing service named Mountain West Digital Library (mwdl.org) which uses ExLibris' Primo to OAI harvest the Dublin Core metadata records of digital artifacts found in digital repositories of the Intermountain West of the United States. After Primo harvests the metadata records, it then indexes them, making them searchable and browseable. I was thinking with Elastic Search, why couldn't Koha replace expensive Primo at mwdl.org. Maybe that is "comparing apples to oranges"? I watched Nick Clemens update on Elastic Search in Koha, which he gave at June's Koha-US meeting (https://youtu.be/hLkVtQ-UHMQ?t=6m4s), but I still have questions. I would like to know how close Koha is to being able to perform OAI harvesting of Dublin Core metadata records and then indexing them the way that Primo does. mwdl.org, and similar institutions, could then switch to Koha. I imagine that academic libraries, special libraries, and large public libraries would save a lot of money by switching to Koha from their expensive discovery layers if Koha, right out of the box, could harvest and index various metadata schemas from their digital collections (ebooks, digital photos, audio/video, maps, manuscripts, papers, etc.). What do you think about this thought? Thanks for reading to the end of my fantasy.
