Expose templated format list to WFS GetFeature and WMS GetFeatureInfo

[dmorissette]

The templated output formats (added in RFC 36, ticket #2576) should be exposed to WFS GetFeature? and WMS GetFeatureInfo? through the use of metadata entries similar to what was done for WMS GetMap? (wms_getmap_formatlist) in ticket #455. i.e.

• Add a "wfs_getfeature_formatlist" which is a comma-delimited list of outputformat names or mime-types to offer for WFS GetFeature?
• Add a "wms_getfeatureinfo_formatlist" which is a comma-delimited list of outputformat names or mime-types to offer for WMS GetFeatureInfo?
• The current "wms_feature_info_mime_type" metadata should be marked as deprecated and the use of "wms_getfeatureinfo_formatlist" encouraged instead

While we're at it, the lookup and parsing of this metadata should be moved to a reusable utility function instead of duplicating the code that is currently found in two places in mapwms.c.

Finally, relevant documentation needs to be updated.

Steve, I find that it's kind of late to get this in beta4 if we want to release someday. Pushing to 6.0 for now as this is not a critical fix but more the completion of a new feature.

[dmorissette]

Well, if you feel strongly about getting this in 5.6 then I'm not completely adverse, but someone would need to grab and complete this before beta4.

Change to 6.0 is ok with me. -Steve

looking into this bug ...

[assefa]

some questions on the getfeatureinfo_formatlist:

• if a user defines a getfeatureinfo_formatlist, do we always include text/plain and GML as supported formats or only expose those listed in the metadata?

• right now, the default output for the GetFeatureInfo? is text/plain if the request does not have the optional INFO_FORMAT parameter. Do we need to keep that if there is a predefined list of format list defined or should we default to the first format in the list. This is tricky, since it would break existing apps expecting always text/plain.

My take would be to always include text/plain and GML + the list of formats defined. Less risque of breaking existing setups.

Added the support for WMS getFeatureInfo. I kept what was there originally where text/plain and GML are always exposed) r9635

Missing WFS and docs

[warmerdam]

I'm looking at implementing the new template support for WFS GetFeature?, as well as my work on integrating OGR output from WFS GetFeature?.

closing. this was implemented. Docs added in r11580 r11581
