Tim Donohue commented on DS-277: -------------------------------- The DSpace Developers discussed this issue (in conjunction with DS-679) on Feb 16, 2011: We need a developer to take the lead on this work, and suggest a possible way to resolve this (and perform a closer review of the https://wiki.duraspace.org/display/DSPACE/DSpaceOAISets work). Full discussion thread follows: [20:09] <tdonohue> Next one -- https://jira.duraspace.org/browse/DS-679 : Modifying dspace oai code to offer harvesting through collection : harvest any item with a request on metadatavalue ... [20:11] <tdonohue> stuartlewis or kshepherd, is DS-679 something you are already working on locally then? ... [20:12] <stuartlewis> If we drove oai-pmh via solr, this sort of virtual set would be trivial. [20:12] <mdiggory> they never liked "Search" in teh OAI-PMH community [20:13] <kshepherd> tdonohue: i was planning on working on it as a feature.. had a few attempts but i think getting familiar with (and improving) discovery is the best first step to 'virtual sets' or 'virtual collections' [20:13] <grahamtriggs> mdiggory: http://www.royalalberthall.com/tickets/bbc-radio3-big-red-nose-show/default.aspx [20:13] <tdonohue> so, is anyone working on driving oai-pmh via Solr? Or wanting to do that? I wouldn't be opposed to the idea, assuming we are still doing valid OAI-PMH [20:14] <grahamtriggs> mdiggory: and yes, I will be in the choir seats for that, with a kazoo.... I also saw a professional choir doing the chorus for the Chicken Run theme on kazoo... [20:14] <mdiggory> theres allot of ways it could get done... OAI-PMH requesthandler inside solr implemented in Java w/ Velocity or XSLT [20:15] <mdiggory> but, I wonder if this stuff is better suited for http://proai.sourceforge.net/ [20:15] <tdonohue> So, is there any more to discuss on DS-679? Or is this just in a "waiting queue" for someone to tackle it :) [20:15] <kshepherd> tdonohue: one of the stumbling blocks i did come up against is the set identifiers.. are they supposed to be persistent? can they be reused? where do we set them? they don't correspond to static DSOs so we can't reserve handles. it can probably be done all through dspace.cfg but that seems messy [20:15] <tdonohue> aha..ok, i can understand that complexity then [20:15] <kshepherd> tdonohue: i'm happy to keep looking at it once i've worked with solr a bit more.. but also happy to help others if they want to take lead on it [20:15] <stuartlewis> Could we comment and close this one, suggesting the reporter looks at the other open tickets for virtual collections? [20:16] <kshepherd> (related jobs are DSCR-12 and DS-277) [20:17] <tdonohue> stuartlewis. I think that's probably a good route forward. I'm assuming it looks like "DS-277" is the most appropriate "main ticket"? [20:18] <mdiggory> http://www.digitalcommonwealth.org/ [20:18] <mdiggory> uses a solr based OAI-PMH engine to search digital collections within Massachusetts. [20:18] <tdonohue> DS-679 -- close issue and mark as "duplicate". Forward user on to DS-277/DSCR-12 for more info. [20:18] * kshepherd notes that there is a community-supplied 'virtual sets' addon at https://wiki.duraspace.org/display/DSPACE/DSpaceOAISets [20:18] <mdiggory> maybe thats the opposite... sorry [20:18] <kshepherd> i'll take a closer look when i have some free time [20:18] <grahamtriggs> I'm not convinced about the request in 679... yes, to virtual sets, but rather than mapping directly to a search / discovery query, it needs to be named sets that map to a defined query [20:19] <tdonohue> grahamtriggs -- either way, we already have a request for OAI virtual sets in DS-277. So, DS-679 is a duplicate idea/request [20:19] <grahamtriggs> so, you can specify an arbitrarily complex query, behind a simple set name [20:20] <kshepherd> grahamtriggs: yep, i think that's the consensus > Make the OAI sets configurable > ------------------------------ > > Key: DS-277 > URL: https://jira.duraspace.org/browse/DS-277 > Project: DSpace > Issue Type: Improvement > Components: OAI-PMH > Affects Versions: 1.6.0 > Reporter: Ben Bosman > Assignee: Ben Bosman > > There is a request to make the sets in OAI more configurable.
