Comments on: The difference between federated search and discovery services http://llyfrgellydd.info/?p=212 It's Welsh for librarian. Fri, 02 Jul 2010 21:02:27 +0000 hourly 1 http://wordpress.org/?v=3.0.1 By: Larry Donahue http://llyfrgellydd.info/?p=212&cpage=1#comment-249 Larry Donahue Tue, 23 Jun 2009 21:30:12 +0000 http://llyfrgellydd.info/?p=212#comment-249 Good discussion. (disclaimer: I'm with a federated search provider, http://www.deepwebtech.com/, and my comments are my own ... ;-) Summon and similar discovery tools are good in the library context, but are less-than-ideal in the enterprise context. The biggest problem, is that in the end, there is a limitation on what other third-party sources you can include in the search. What I've heard, is that being able to include some competitive content, or content not available through an API, or is internal (and therefore unique), you're going to still be looking for a federated solution. I would love to hear about people's specific experience regarding this. Larry. Good discussion.

If I recall correctly, the metadata is reharvested nightly. David, we recently had a representative from Serials Solutions come to talk to us about Summon.

Thornton Wed, 03 Jun 2009 06:55:35 +0000 http://llyfrgellydd.info/?p=212#comment-237 My concern with the discovery tools like Summon and the new EBSCO one, is how often they are updated (how often the metadata is re-harvested). With federated searching, you send our multiple searches to the current version of the relevant databases (I presume?), but with the Summon-type system there's the danger that you will searching within (slightly) out--of-date content. DO Serials Solutions, EBSCO et al. indicate clearly how often their data is up-dated?

I think what you've described is how a search engine like Google works, but I think discovery services *receive* files from the vendors and publishers, which they then include in their proprietary index. The end result is the same, as is your list of benefits. I have a slightly different interpretation on how the discovery services work.
