OpenSearch Support¶
pycsw supports the OGC OpenSearch Geo and Time Extensions 1.0 standard via the following conformance classes:
- Core (GeoSpatial Service)
{searchTerms}
,{geo:box}
,{startIndex}
,{count}
- Temporal Search core
{time:start}
,{time:end}
OpenSearch support is enabled by default. HTTP requests must be specified with mode=opensearch
in the base URL for OpenSearch requests, e.g.:
http://localhost/pycsw/csw.py?mode=opensearch&service=CSW&version=2.0.2&request=GetCapabilities
This will return the Description document which can then be autodiscovered.
OpenSearch Temporal Queries¶
By default, pycsw’s OpenSearch temporal support will query the Dublin Core dc:date
property. To
enable temporal extent search, set profiles=apiso
which will query the temporal extents of
a metadata record (apiso:TempExtent_begin
and apiso:TempExtent_end
).
At the HTTP API level, time is supported via one of time=t1/t2
or start=t1&stop=t2
. If the
time
parameter is present, it will override either/both of the start
and stop
parameters
respectively.
