[MapServer-users] OGC API – Features Part 3 (Filtering) implementation status

[oliver.eberli at bd.zh.ch]

Hi all,
Hi Seth,

thank you very much for your replies and the helpful pointers.
We are very interested in seeing this feature developed. In that context, I’d also like to understand what kind of budget would typically be required for such an implementation?
Could you advise on the appropriate point of contact to discuss potential funding or sponsorship for this work?

If other organizations are interested as well, please feel free to join the discussion, we’d be happy to explore combining resources.

Thanks again, and best regards,
Oli

Hi Oli,

I am unaware of any work being undertaken on this feature. Without funding, or a requirement for this from a core developer, it likely won't be implemented.

The most recent work on the OGC Features API (implementation of Part 2 [1]) was written by Spatialys, listed under https://mapserver.org/community/service_providers.html. If any other organisations are interested in the feature, then maybe reply to this thread to combine resources.

Hi all,



We would like to offer OGC API Features for our organization and the public. Since we already use MapServer in production, it would be the natural choice to provide this service via MapServer as well.



While evaluating the current OGC API Features implementation, we noticed that filtering capabilities as defined in OGC API – Features Part 3 (Filtering) are not yet implemented. According to the documentation from 2021, the status is still marked as “not in progress.” (https://www.mapserver.org/development/rfc/ms-rfc-134.html or https://www.mapserver.org/ogc/ogc_api.html#ogcapi)



Could you please let us know whether there is any updated roadmap or timeline for the implementation of Part 3 (Filtering) in MapServer? Any information on planned development stages or priorities would be greatly appreciated.

Thank you very much for your time and effort.



Cheers

Oli
