Well, that's my question. I have the micro view of linked data, I think - it's a distribution/self-describing format. But I don't see the big picture.
In the non-techie library world, linked data is being talked about (perhaps only in listserv traffic) as if the data (bibliographic data, for instance) will reside on remote sites (as a SPARQL endpoint??? We don't know the technical implications of that), and be displayed by <your local catalog/the centralized inter-national catalog> by calling data from that remote site. But the original question was how the data on those remote sites would be <access points> - how can I start my search by searching for that remote content? I assume there has to be a database implementation that visits that data and pre-indexes it for it to be searchable, and therefore the index has to be local (or global a la Google or OCLC or its bibliographic-linked-data equivalent). All of the above parenthesized or bracketed concepts are nebulous to me.

I assume an index would have to be database implementation specific, while data is typically exposed for external consumption via implementation-agnostic protocols/formats, like a SPARQL endpoint or a REST API. How do you locally index something remote under these constraints? -Sarah > Cindy Harper > > -----Original Message----- > From: Harper, Cynthia > Sent: Tuesday, February 24, 2015 1:20 PM > To: auto...@listserv.syr.edu; 'Williams, Ann' > Subject: RE: linked data question > > What I haven't read, but what I have wondered about, is whether so > far, linked DATA is distributed, but the INDEXES are local?
