---------------------------------------
Summary: Support <gmd:valueUnit>
Key: SIS-289
URL: https://issues.apache.org/jira/browse/SIS-289
Project: Spatial Information Systems
Issue Type: Sub-task
Components: Metadata
Affects Versions: 0.5, 0.4, 0.3, 0.6
Reporter: Martin Desruisseaux
{{<gmd:DQ_QuantitativeResult>}} contains a {{<gmd:valueUnit>}} property. This
unit can be specified by a link to an external definition like the following
examples:
* {{<gmd:valueUnit xlink:href="urn:ogc:def:uom:EPSG::9001"/>}}
* {{<gmd:valueUnit xlink:href="urn:ogc:def:uom:OGC:1.0:metre"/>}}
Alternatively, the unit definition can be included in the XML document by
inserting one of the following elements as the {{<gmd:valueUnit>}} value (see
[details|http://www.datypic.com/sc/niem21/e-gmd_valueUnit-1.html]):
* {{<gml:UnitDefinition>}}
* {{<gml:BaseUnit>}}
* {{<gml:DerivedUnit>}}
* {{<gml:ConventionalUnit>}}
Example (see [GML from
EPSG|http://epsg-registry.org/export.htm?gml=urn:ogc:def:uom:EPSG::9001]):
{code:xml}
<gmd:valueUnit gml:id="m">
<gml:BaseUnit gml:id="epsg-uom-9001">
<gml:identifier
codeSpace="OGP">urn:ogc:def:uom:EPSG::9001</gml:identifier>
<gml:name>metre</gml:name>
<gml:remarks>Also known as International metre. SI standard
unit.</gml:remarks>
<gml:quantityType>length</gml:quantityType>
<gml:unitsSystem xlink:href="http://www.bipm.fr/en/si"/>
</gml:BaseUnit>
</gmd:valueUnit>
{code}
Apache SIS currently does not support any of the above.
