Hi,
My exercise is to apply Observations&Measurements for my own observation
database in PostGIS
I defined myns:Observation as specialization of om:OM_Observation, so
myns:Observation inherits all attributes from om: and has its own.
I mapped it like this:
<FeatureTypeMapping>
<sourceDataStore>datastore</sourceDataStore>
<sourceType>testdata_toc</sourceType>
<targetElement>toc2:Observation</targetElement>
<attributeMappings>
<AttributeMapping>
<targetAttribute>toc2:Observation</targetAttribute>
<idExpression>
<OCQL>Concatenate('OB_', occ_type, occ_id)</OCQL>
</idExpression>
</AttributeMapping>
<AttributeMapping>
<targetAttribute>om:phenomenonTime</targetAttribute>
<idExpression>
<OCQL>Concatenate('T_', occ_type, occ_id)</OCQL>
</idExpression>
<targetAttributeNode>gml:TimeInstantPropertyType</targetAttributeNode>
</AttributeMapping>
<AttributeMapping>
<targetAttribute>om:phenomenonTime/gml:TimeInstant/gml:timePosition</targetAttribute>
<sourceExpression>
<OCQL>timespan_begin</OCQL>
</sourceExpression>
<ClientProperty>
<name>frame</name>
<value>'#ISO-8601'</value>
</ClientProperty>
</AttributeMapping>
I also defined namespace element in mapping, added secondary workspace om:
and have app-schema-cache for om.
<Namespace>
<prefix>om</prefix>
<uri>"http://www.opengis.net/om/2.0"</uri>
</Namespace>
I did everything I could find on Geoserver documentation pages to secure
reading of om: namespace, but still have exception:
Internal error occurred Error applying mapping with targetAttribute
toc2:Observation Error applying mapping with targetAttribute om:metadata
om:metadata is not a valid location path for type
http://loom-gis.geo.ut.ee/ermas/schemas/toc2:ObservationType.
om:phenomenonTime ns: "http://www.opengis.net/om/2.0", ObservationType
properties: ..... http://www.opengis.net/om/2.0#type,
http://www.opengis.net/om/2.0#metadata,
http://www.opengis.net/om/2.0#relatedObservation,
http://www.opengis.net/om/2.0#phenomenonTime,
http://www.opengis.net/om/2.0#resultTime, .... etc.
Is it something esle I need to define to be able to read om: elements?
Looking forward for your reply.....

Valentina,
there should not be quotes inside the <uri> element:
<uri>"http://www.opengis.net/om/2.0"</uri>
app-schema is lenient and will allow you to include quotes in your namespace! This is incorrect.
Instead use this:
<uri>http://www.opengis.net/om/2.0</uri>
Kind regards,
Ben.

No problem at all. Taking the time to ask your question on the lists helps others searching for solutions, so thanks!
Kind regards,
Ben.
