CSW ISO Metadata Profile Mapping File¶

General¶

See Mapping Files for basic information on the CSW mapping file. The ISO Metadata mapping can be found in the file csw/MD_Metadata.properties inside the data directory.

Below is an example of an ISO Metadata Profile Mapping File:

@fileIdentifier.CharacterString=id
identificationInfo.MD_DataIdentification.citation.CI_Citation.title.CharacterString=title
identificationInfo.MD_DataIdentification.citation.CI_Citation.alternateTitle.CharacterString=list(description,alias,strConcat('##',title))
identificationInfo.MD_DataIdentification.descriptiveKeywords.MD_Keywords.keyword.CharacterString=keywords
identificationInfo.MD_DataIdentification.abstract.CharacterString=abstract
$dateStamp.Date= if_then_else ( isNull("metadata.date") , 'Unknown', "metadata.date")
hierarchyLevel.MD_ScopeCode.@codeListValue='http://purl.org/dc/dcmitype/Dataset'
$contact.CI_ResponsibleParty.individualName.CharacterString=
identificationInfo.MD_DataIdentification.resourceConstraints[0].MD_LegalConstraints.accessConstraints.MD_RestrictionCode=
identificationInfo.MD_DataIdentification.resourceConstraints[1].MD_SecurityConstraints.classification.MD_ClassificationCode=
identificationInfo.MD_DataIdentification.citation.CI_Citation.date%.CI_Date.date.Date=lapply("metadata.citation-date", if_then_else(isNull("."), "Expression/NIL", dateFormat('YYYY-MM-dd', ".")))
identificationInfo.MD_DataIdentification.descriptiveKeywords.MD_Keywords.keyword.CharacterString=list(keywords, if_then_else(equalTo(typeOf("."), 'FeatureTypeInfo'), 'vector', 'raster'))

The full path of each field must be specified (separated with dots). XML attributes are specified with the @ symbol, similar to the usual XML X-path notation. To avoid confusion with the identifier-symbol at the beginning of a mapping line, use \@ (for an attribute that is not an identifier) or @@ (for an attribute that is also the identifier) - see the feature catatalog mapping file for an example.

The % symbol denotes where a multi-valued mapping should be split in to multiple tags. Multiple % symbols may be used for multi-dimensional mappings - see the feature catatalog mapping file below for an example.

Indexes with square brackets can be used to avoid merging tags that shouldn’t be merged, as demonstrated above for resourceConstraints.

To keep the result XSD compliant, the parameters dateStamp.Date and contact.CI_ResponsibleParty.individualName.CharacterString must be preceded by a $ sign to make sure that they are always included even when using property selection.

The lapply function can be used to apply expressions to items of lists, which can be handy with multidimensional fields.

The typeOf function (exclusive to CSW-ISO module) returns the type of the catalog item that is being processed (LayerGroupInfo, FeatureTypeInfo, CoverageInfo,…), which can be handy if you for example need to handle vector layers differently to raster layers.

Feature Catalogs¶

Within the ISO Metadata Profile, there is also support for Feature Catalogues that contain information about vector layer type metadata. As specified by the ISO Metadata standard these are exposed in separate records. For this purpose we have a separate mapping file::

@@uuid=”metadata.custom.feature-catalog/feature-catalog-uidentifier” @id=”metadata.custom.feature-catalog/feature-catalog-identifier” $featureType.FC_FeatureType.typeName.LocalName=concatenate(“name”, ‘Type’) $featureType.FC_FeatureType.isAbstract.Boolean=’false’ $featureType.FC_FeatureType.featureCatalogue.@uuidref=”metadata.custom.feature-catalog/feature-catalog-identifier” featureType.FC_FeatureType.definition.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-type-definition” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.memberName.LocalName=”metadata.custom.feature-catalog/feature-type/feature-attribute/name” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.valueType.TypeName.aName.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-attribute/type” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.length.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-attribute/length” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.definition.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-attribute/definition” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.cardinality.Multiplicity.range.MultiplicityRange.lower.Integer=”metadata.custom.feature-catalog/feature-type/feature-attribute/min-occurrence” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.cardinality.Multiplicity.range.MultiplicityRange.upper.UnlimitedInteger=”metadata.custom.feature-catalog/feature-type/feature-attribute/max-occurrence” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.cardinality.Multiplicity.range.MultiplicityRange.upper.UnlimitedInteger.@isInfinite=false featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.listedValue%.FC_ListedValue.label.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-attribute/domain/value” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.listedValue%.FC_ListedValue.definition.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-attribute/domain/definition” featureType.FC_FeatureType.carrierOfCharacteristics%.FC_FeatureAttribute.listedValue%.FC_ListedValue.code.CharacterString=”metadata.custom.feature-catalog/feature-type/feature-attribute/domain/code”

Only records that have a non-null identifier in the catalog mapping file will have a feature catalogue record. There is no support in the standard Geoserver GUI for user configuration of this information. The upcoming metadata community module makes this possible.
