The latest release of the YAZ toolkit adds an important new feature: Support for the SOLR WSAPI in yaz-client and the ZOOM client-side API.
What does this mean? In a nutshell, it allows you to search resources supporting all released versions of Z39.50, SRU and SRW (SRU wrapped in SOAP), and now also SOLR-based targets, all from a single application codebase, and in parallel. As a bonus, you can pull facets straight out of SOLR results from within the YAZ/ZOOM API.
You’ll find more details of our thinking behind this extension in this blog post.
