Subject [jira] [Created] (SIS-289) Support <gmd:valueUnit>
Date Wed, 02 Sep 2015 16:45:46 GMT
Martin Desruisseaux created SIS-289:

             Summary: Support <gmd:valueUnit>
                 Key: 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|]):

* {{<gml:UnitDefinition>}}
* {{<gml:BaseUnit>}}
* {{<gml:DerivedUnit>}}
* {{<gml:ConventionalUnit>}}

Example (see [GML from EPSG|]):

<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:remarks>Also known as International metre. SI standard unit.</gml:remarks>
        <gml:unitsSystem xlink:href=""/>

Apache SIS currently does not support any of the above.
