Hi,
There is an issue that discuss the MIME type override:
https://osgeo-org.atlassian.net/browse/GEOS-8224
Resuming the discussing, MIME type and file extensions are related but are two
different things.
The fix made for WFS 2.0 changed the default MIME type for WFS 2.0 GML32
responses, but didn't
do anything about the file extension.
The browser and pretty much any other client that needs to something with the
content
will look at the MIME type to interpret the content.
So changing the MIME type should make your browser show the response content
but will not do
nothing about the file extension (that's another issue).
So if you select let's say 'text\xml' as the override MIME type and do a
GetFeature request does the
response get display in the browser ? and if not which MIME does you response
have ?
Regarding the drop-down menu in the WFS settings. In GeoServer it is possible
to configure a
service settings per workpsace (virtual services). The blank represents the
global service configuration
and the other values (in your case sar) should correspond to existing
workspaces and allows
you to configure those workspaces virtual service settings.
You can read more about GeoServer virtual services here:
http://docs.geoserver.org/stable/en/user/configuration/virtual-services.html

Nuno Oliveira

Hi Ben,
With regards to the GML 3.2 MIME type issue, your solution didn't work for me
using 2.12 nightly build from mid June. However I believe that the issue is
that changing the MIME type via the dropdown menu in WFS settings doesn't seem
to do anything. I get .application files no matter what I select. However, I
have not tried restarting Geoserver after applying settings. Does changing
these settings require a restart???
Also, I've noticed that there is a workspace dropdown menu in the WFS settings page but it only
offers " " and "sar" as options. What is that dropdown for?

Gavin,
I have not looked at the types involved in your case, but one of the new
changes on master is more thorough searching of substitution groups when
encoding properties of complex types:
[GEOT-5667] Fix app-schema property substitution group support
https://osgeo-org.atlassian.net/browse/GEOT-5667
<https://osgeo-org.atlassian.net/browse/GEOT-5667>
This has not yet been backported to stable (2.11.x). I was wondering about
performance and would like to benchmark it before backporting.
The new default "application/gml+xml; version=3.2" MIME type is a recent
fix on master to conform to WFS 2.0:
[GEOS-8140] GeoServer uses invalid mime type for GML 3.2 responses
https://osgeo-org.atlassian.net/browse/GEOS-8140
<https://osgeo-org.atlassian.net/browse/GEOS-8140>
You can change the MIME type back to "text/xml; subtype=gml/3.2" or
"text/xml" in the global WFS settings, which will cause it to be displayed in your
browser:
http://docs.geoserver.org/latest/en/user/services/wfs/webadmin.html#override-gml-3-2-mime-type
<http://docs.geoserver.org/latest/en/user/services/wfs/webadmin.html#override-gml-3-2-mime-type>
Kind regards,
Ben.

Hi everyone,
I just wanted to follow up on the subject of using Geoserver App Schema
to
output WFS requests in the GeodesyML schema. I found a solution but I
can't
explain why it works.
First, in the example mapping file I provided (quoted down below) my
<targetAttribute> XPath was incorrect. It should have read
geo:siteLog/geo:siteIdentification/geo:siteName. However, upon
implementing
the correct XPath the output still didn't resolve. *I upgraded my
Geoserver
instance from 2.11.1 to 2.12 SNAPSHOT and suddenly it worked.* Perhaps
someone else can explain why but it seems that 2.11 has problems
resolving
XPaths when abstract XML types are involved.
Lastly, for some reason the GeodesyML output file gets automatically
downloaded with a .application extension rather than displaying in the
browser; also not sure why. I hope this can save someone frustration
down
the line.

Gavin,
it looks to me like GeodesyML is a GML 3.2.1 application schema:
https://github.com/GeoscienceAustralia/GeodesyML/
<https://github.com/GeoscienceAustralia/GeodesyML/>
This means that it will only work with GML 3.2 output from
GeoServer.
Either select a GML 3.2 output format, use WFS 2.0 (which defaults
to
GML 3.2), or manually add outputformat=gml32 to a WFS 1.1 request.
You will likely also have to define secondary namespaces:
http://docs.geoserver.org/latest/en/user/data/app-
<http://docs.geoserver.org/latest/en/user/data/app->
schema/supported-gml-versions.html
http://docs.geoserver.org/latest/en/user/data/app-
<http://docs.geoserver.org/latest/en/user/data/app->
schema/secondary-namespaces.ht <http://secondary-namespaces.ht>ml
schemaUri must be a URL. You can have multiple elements. The
top-level
one might be this, but I do not know if it includes
monumentInfo.xsd:
https://github.com/GeoscienceAustralia/GeodesyML/
<https://github.com/GeoscienceAustralia/GeodesyML/>
blob/master/schemas/geodesyML.xsd
app-schema will cache it for you. Use a better URL if you have one
(e.g.
from geodesyml.org <http://geodesyml.org>).
I do not know GeodesyML and do not know what type you should choose.
Perhaps geo:Site? This is the thing that goes on targetElement.
Where is the siteName you mentioned? Could you use the gml:name
inherited from gml:AbstractFeatureType? The property name goes in
targetAttribute.
Deciding how to map your database to the XML schema is, according to
reports, 2/3 of the work.
Kind regards,
Ben.

Hi,
I am trying to have a Geoserver display GML its output in the
GeodesyML
schema, outlined here
<https://geoscienceaustralia.github.io/GeodesyML-Github-Pages/
<https://geoscienceaustralia.github.io/GeodesyML-Github-Pages/>> . In
particular, I am working with GPS monument meta data. For now
I'm trying
to
just output the siteName in GeodesyML schema when I click GML
in the
Layers
Preview in Geoserver. The relevant XML schema definition file
for
GeodesyML
is called monumentInfo.xsd. Unfortunately, I can't seem to get
the
mapping
correct from my database schema to GeodesyML. In particular I
think the
problem is in the <targetElement> or <targetAttribute> fields
within
<FeatureTypeMapping>. I concluded that I should use
geo:GeodesyML as the
argument to schemaUri because it is the only xsd file with a
top level
element (type GeodesyMLType).
How can I use the schema outlined in the monumentInfo.xsd schema
definition?
Specifically here, how can I map site_name in my database
schema to
siteName
in the GeodesyML schema?
Any help is sincerely appreciated and I apologize if my lack of
familiarity
with XML is causing me to ask a silly question. I have done a
fair bit
of
Google research. The tutorial I followed to get this far is
here
<http://docs.geoserver.org/latest/en/user/data/app-schema/tutorial.html
<http://docs.geoserver.org/latest/en/user/data/app-schema/tutorial.html>>
,
with supporting documentation here
<http://docs.geoserver.org/stable/en/user/data/app-
<http://docs.geoserver.org/stable/en/user/data/app->
schema/mapping-file.html>
but they are using GeoscienceML, not GeodesyML.
