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. There are two ways to access SRU depending on the deployment pattern chosen.

OGC API - Records deployment

http://localhost:8000/sru

CSW legacy deployment

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 https://www.loc.gov/standards/sru/misc/simple.html for example SRU requests.
