The OGC is has published the "OpenSearch Geo and Time Extensions". That specification is based on, but extends, the OpenSearch Geo extension and OpenSearch Time extension.

As it turns out, I'm working on an open source (C#) implementation of the client side for OpenSearch. I'd like to include support for the OGC extensions to query by Geo and Time.

There are publicly available servers that implement the Geo and Time extensions, especially in the earth observation area (e.g. NASA Echo). However they don't implement the "extra" bits defined by OGC.

Are there any publicly available servers that implement any of the OGC extensions to the original OpenSearch Geo/Time extensions? In particular, I'm looking for implementations that expose the spatial and temporal containment operations ("relation" parameter).

Publicly available is preferred because:

  • Saves work in setting up a test server
  • Unit tests can be written that use it directly
  • Avoids confirmation bias in testing

However in the absence of publicly available, anything implementing the draft OGC spec (even "git branch" level maturity) would be better than what I have now.

    Is this question relevant any longer assuming that the specification has been out for some time now? – kttii Oct 17 '16 at 15:32
  • I think it is still relevant - it isn't really about the state of the extension, but rather about test servers. The first paragraph was outdated and I've reworked it, but the test of it stands. – BradHards Oct 17 '16 at 21:00

    In the specification document there is a list of contacts, perhaps they would know of implementations. I had a feeling that implementations must exist prior to an OGC standard being published... – nmtoken Oct 18 '16 at 7:58

    This question caught my attention because it was old, unanswered and upvoted. Closing as I have done is one way to move it from the unanswered list but the other way is to provide an answer that says "As far as I know there are none". To this question I could not say that with authority but as the asker you could certainly provide that as a self-answer. If you wish to do that ping me and I'll be happy to insta-open it. – PolyGeo Mar 30 '18 at 6:59

    I'll do another scan, and try to provide a self-answer one way or the other. – BradHards Apr 1 '18 at 1:49
