Hi Ben and Andrea,
Thanks for the feedback !
I should have read OGC filter specification [1] more carefully before sending this mail ... sorry
about that :(
Long story short ... according to the relevant specification [1] (and my understanding of it) both
relative,
full paths, qualified or unqualified paths should be accepted:/
/
/(...) In addition, property names *may be qualified* with a namespace
prefix in which case the
name /
/must //conform to the Namespaces In XML [9] specification. (...)/
/(...)Notice that in this instance, each relative location path begins with
the root element of the/
/feature property being referenced. This simply corresponds to the name of
the feature/
/property. *Optionally, each XML element within the description may be
referenced with*/*
**/the relative location path beginning with root element of the feature
(i.e. the name of the/**
*/*feature type).* Thus the lastName property could be reference as
Person/lastName, the/
/City element could be referenced as Person/mailAddress/Address/city and so
on.(...)/
//The full description of /PropertyName /element is available in reference [1] in section /6
Properties /starting
at page 4 (page 14 in the PDF reader).
Let's see if I can find time next week to take a look at GeoServer \ GeoTools and check how
difficult it will
be to support this behavior and what is the current behavior of
/XmlXPathPropertyAcessor/ :)
Cheers,
Nuno Oliveira

Since the geometry is in a sub element it will not be recognized as the
default geometry and
we need
to specify in the SLD the geometry XPath. My first try was to use the
following XPath:
<ogc:PropertyName>*st:Station**/*st:position/st:location</ogc:PropertyName>
To my surprise this didn't work, after debugging the code it looks like the
root feature type
should not
be provided at the start of the XPath, so this is what should be used:
<ogc:PropertyName>*st:position/st:location*</ogc:PropertyName>
Yep, that makes it consistent with simple features, where the full path is
never used.
Conclusion, the way of referencing properties of App-Schema defined feature
types is different
in WFS and WMS (at least for GetFeatrue and SLDs).
In my opinion the WFS GetFeature full XPath path is the most natural one
and both WFS and
WMS should use \ accept the same XPath.
I would never have thought of using the full path, but I don't play with
complex features, so that
probably explains it :-p
I propose to allow the use of the full XPath in WMS (equal to WFS) but keep
accepting the shorten
one in WMS for compatibility reasons, opinions ?
And also keep it for consistency with simple features and common usage in SLD:
check SLD cookbook,
but also the SLD specification, all of the examples use single unqualified
names.
Ideally, it would be best if one could use short relative paths or full
qualified paths in both cases,
simple features and complex features, to have a good overall consistency (e.g.,
someone using
mostly complex features might end up using full path for simple ones as well).
It's likely already handled as a fallback by the XmlXPathPropertyAcessor, but
does not
hurt checking.
Cheers
Andrea
