Hi, Interesting use case indeed, er:MineralOccurrence is not a simple property so it seems that App-Schema does handle it correctly. Quick suggestion: give it a quick try with the recently introduced syntax for SQL mappings with cardinality 0\2..N: https://docs.geoserver.org/stable/en/user/data/app-schema/mapping-file. html#attributes-with-cardinality-1-n Best regards, Nuno Oliveira On Thu, 2018-12-13 at 02:25 +0000, Sexton Michael wrote: > Hi > > I’m following the example mapping file here to map a simple attribute > field from another table multiple times: > > https://github.com/geoserver/geoserver/blob/master/src/extension/app- > schema/app-schema-test/src/test/resources/test- > data/SimpleAttributeFeatureChainTest.xml > > This is the mapping file: > > <typeMappings> > <FeatureTypeMapping> > <sourceDataStore>datastore</sourceDataStore> > <sourceType>MV_ER_MINERALOCCURRENCE</sourceType> > <targetElement>er:MineralOccurrence</targetElement> > > <attributeMappings> > <AttributeMapping> > > er:MineralOccurrence > <idExpression> > <OCQL>GML_ID</OCQL> > </idExpression> > </AttributeMapping> > <AttributeMapping> > <targetAttribute>gml:identifier</targetAttribute> > <sourceExpression> > <OCQL>IDENTIFIER</OCQL> > </sourceExpression> > <ClientProperty> > <name>codeSpace</name> > <value>IDENTIFIER_CODESPACE</value> > </ClientProperty> > </AttributeMapping> > <AttributeMapping> > <targetAttribute>gml:name</targetAttribute> > <sourceExpression> > <OCQL>NAME</OCQL> > </sourceExpression> > </AttributeMapping> > > <AttributeMapping> > <targetAttribute>er:sourceReference</targetAttribute> > <sourceExpression> > <OCQL>ENO</OCQL> > <linkElement>SOURCEREFERENCE</linkElement> > <linkField>FEATURE_LINK[2]</linkField> > </sourceExpression> > </AttributeMapping> > </attributeMappings> > </FeatureTypeMapping> > <FeatureTypeMapping> > <mappingName>SOURCEREFERENCE</mappingName> > <sourceDataStore>datastore</sourceDataStore> > <sourceType>MV_ER_SOURCEREFERENCE</sourceType> > <targetElement>er:sourceReference</targetElement> > <attributeMappings> > > <AttributeMapping> > <targetAttribute>er:sourceReference</targetAttribute> > <ClientProperty> > <name>xlink:href</name> > <value>URI</value> > </ClientProperty> > > <ClientProperty> > <name>xlink:title</name> > <value>TITLE</value> > </ClientProperty> > </AttributeMapping> > <AttributeMapping> > <targetAttribute>FEATURE_LINK[2]</targetAttribute> > <sourceExpression> > <OCQL>ENO</OCQL> > </sourceExpression> > </AttributeMapping> > </attributeMappings> > </FeatureTypeMapping> > > > The sourceReference attribute is defined in http://schemas.earthresou > rceml.org/2.0/mineralOccurrence.xsd as: > > > nillable="true"> > <annotation> > <appinfo> > > >gmd2:CI_Citation; > </appinfo> > </annotation> > <complexType> > <complexContent> > <extension base="gml:AbstractMetadataPropertyType"> > <sequence/> > > ref="gml:AssociationAttributeGroup"/> > </extension> > </complexContent> > </complexType> > </element> > > But I get this error: > > Error occurred getting featuresjava.util.NoSuchElementException: No > top level element found in schemas: {http://xmlns.earthresourceml.org > /EarthResource/2.0}sourceReferenceNo top level element found in > schemas: > {http://xmlns.earthresourceml.org/EarthResource/2.0}sourceReference > > I’ve seen this error before, when trying to map gml:metadataProperty, > which I managed to get around using the targetAttributeNode, eg: > > <mappingName>METADATA</mappingName> > <sourceDataStore>datastore</sourceDataStore> > <sourceType>MV_CIT_CI_CITATION</sourceType> > <targetElement>gml:metaDataProperty</targetElement> > <attributeMappings> > > <AttributeMapping> > > gml:metaDataProperty/gml:GenericMetaData > ibute> > > mrl:LI_Source_PropertyType > </AttributeMapping> > > > But in the case of er:soruceReference, there is no node to map to. > It’s a reference intended to have xlink:href and xlink:title > attributes.
