[Geoserver-users] App-Schema Mapping File to GeodesyML

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/> . 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> ,
with supporting documentation here
<http://docs.geoserver.org/stable/en/user/data/app-schema/mapping-file.html>
but they are using GeoscienceML, not GeodesyML.

Gavin,

it looks to me like GeodesyML is a GML 3.2.1 application schema:
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-schema/supported-gml-versions.html
http://docs.geoserver.org/latest/en/user/data/app-schema/secondary-namespaces.html

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/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).

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 Ben,

Thanks for your response! From what I can tell, the community as a whole is
pretty new to GeodesyML. I followed your advice and definitely made
progress but I do have some followup questions.

1) Here is the request I am using, it specifies WFS version 1.1.0 and GML
version 3.2:
http://localhost:8080/geoserver/ows?service=WFS&version=1.1.0&request=GetFeature&typeName=gps_as:GeodesyML&outputFormat=gml32&maxFeatures=50
2) I created the secondary namespace as suggested and ensured that the gml
namespace matches between the namespace.xml file, the GeodesyML schema, and
my mapping file (http://www.opengis.net/gml/3.2).
3) I replaced the locally hosted .xsd reference in <schemaUri> with:
https://raw.githubusercontent.com/GeoscienceAustralia/GeodesyML/master/schemas/geodesyML.xsd
(I can't find a better source for it, the schema may still be under active
development?).

Now the new stuff. Upon some further reading into how XML schemas work (yay
wikibooks!) I discovered that my XPath expression for <targetAttribute> was
totally incorrect. I've included a mapping file snippet below, showing the
<targetTypes> block and the <typeMappings> block of my fixed mapping file.
This change stopped the generation of errors upon performing a WFS request.
Unfortunately, I still don't see the mapped features in the output.
Instead, I seem to get ONLY the gml:id out. I included an example of the
WFS request output below, requesting only 5 results. What really puzzles me
is that I specified <encodeIfEmpty>true</encodeIfEmpty> in the
<AttributeMapping> for site_name and station_code so I would expect to at
least see the fields. What's going on here?

Thanks for your help,

Gavin

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,

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

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

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

Kind regards,
Ben.

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?

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,

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

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.

Gavin,

the dropdown is for per-workspace settings (blank meaning global).
Restart should not be required, just hitting the save button at the end
of the page. Are you using virtual (per-workspace) service endpoints?
There is a bug that causes MIME type override to not work for virtual
services:

[GEOS-8224] On a GetFeature WFS 2.0 request on a virtual service is not
possible anymore to get the response in browser
https://osgeo-org.atlassian.net/browse/GEOS-8224

Kind regards,
Ben.
