Implementation in Proteus Schema
AreaUnit is only used as the type of the Unit attribute of Area. Area is implemented using DEXPI generic attributes for physical quantities. In a <GenericAttribute>
element, the AreaUnit literal is given by means of its RDL reference in the table above. The Units
attribute of the element is the name of the RDL reference in camel-case; it equals the name of the literal. The UnitsURI
attribute of the element is the URI of the RDL reference.
Example
Implementation in Proteus Schema
<GenericAttribute
Units="MetreSquared"
UnitsURI="http://data.posccaesar.org/rdl/RDS1358009" ...>
Note that the <GenericAttribute>
element must have further attributes (Format
, Value
, Name
, and AttributeURI
). See the implementation examples for Area and for the FilterArea attribute of FilterUnit.
