Search/Retrieval via URL (SRU) Support

pycsw supports the Search/Retrieval via URL search protocol implementation as per subclause 8.4 of the OpenGIS Catalogue Service Implementation Specification.

SRU support is enabled by default. HTTP GET requests must be specified with mode=sru for SRU requests, e.g.:

http://localhost/pycsw/csw.py?mode=sru&operation=searchRetrieve&query=foo

See http://www.loc.gov/standards/sru/simple.html for example SRU requests.
