Support for time in GML coverage output

[Dimitar Misev]

Only integer/floats are supported by GML, so having a time axis can not be encoded in the coverage output, or it can be encoded by breaking the XML schema validation.

I am afraid this will not be possible Dimitar, as I got it from some discussion in the OGC mailing lists.
Temporal coordinates will need to be printed as they are (numbers): the application, knowing the temporal CRS, will be able to convert them to dates/timestamps.

What we can/will do is allow dates/timestamps in the W*S requests.

?

[Dimitar Misev]

Yes so one idea is to break the schema anyway for users who are fine with that.

We could introduce a flag in petascope.properties to enable/disable this.

[Dimitar Misev]

I'm not sure, how can we proceed with this? Closing as wontfix?

[Piero Campalani]

I think so, we would lose OGC compliance.
Time can be handled in input queries, both WCS and WCPS, but we keep numeric coords in the GML.
