Index Data has released Version 1.0.1 of Pazpar2, an open source Z39.50 client.
Here’s an excerpt from the press release:
Pazpar2 . . . can be viewed either as a high-performance metasearching middleware or a Z39.50 client with a webservice interface, depending on your perspective and needs. It is a fairly compact C program—a resident daemon—that incorporates the best we know how to do in terms of providing high performance, user-oriented federated searching. . . .
One cool thing it does is search many databases in parallel, and do it fast, without unduly loading up the user interface. . . It retrieves a set of records from each target, and performs merging, deduplication, ranking/sorting, and pulls browse facets from them. . . .
It doesn’t know anything about data models, so you can handle exotic data sources if you need to. . . you use XSLT to normalize data into an internal model—we provide examples for MARC21 and a DC-esque internal model, and configure ranking, facets, sorting, etc., from that. . . .
