Hi Andrea,

You bring up some valid points that should be fixed/addressed. Obviously
this can be fixed.

However, I would advise to not make a big fuss about this issue and stay
pragmatic and focused. Open individual bug reports for each of the
non-compliance behavior and back it up with references to the WMS spec.
Don't put more than one issues in the bug report but create several
reports for each issue. This way it is easier to address and discuss.

I can maybe help to understand how the GetPrint command ended up in the
GetCapabilities response. When QGIS Web Client was developed there was a
print command lacking. Since WMS did not provide a way to point to
certain pre-defined layout and specify the necessary parameters we
decided to extend the WMS capabilities of QGIS server. The spec (at
least in the days of WMS 1.1 when this was added) was not very clear
about these extensions.

Later, we introduced a request called "GetProjectSettings", which
actually is an extended "GetCapabilities" request - here we can now
extend according to our requirements without having to violate other
standard requests. The GetProjectSettings response contains a lot of
"non-standard" information that is used between QGIS server and QGIS web
client - things like layout information, widget information, data types,
etc.

Now that the GetProjectSettings command exists we could actually remove
the GetPrint from the GetCapabilities response or we could try to be
standard-compliant by using an extension mechanism.

It is not true that QGIS people do not care about standards - but it is
a lot of effort to make sure everything really complies properly and
works interoperable. Even if QGIS would be fully standards compliant it
does not necessarily means it is fully interoperable as the
specification does not answer everything.

You can help to make QGIS server more standards compliant, but you have
to properly document this (with links to specifications) and find a
developer willing to work on this.

I am quite confident that these issues can be resolved.

Andreas
