--------------------------------------

             Summary: org.apache.sis.metadata.PropertyDescriptor to implement 
org.opengis.feature.type.PropertyDescriptor
                 Key: SIS-80
                 URL: https://issues.apache.org/jira/browse/SIS-80
             Project: Spatial Information Systems
          Issue Type: Task
          Components: Metadata
            Reporter: Martin Desruisseaux
            Priority: Minor


The {{org.apache.sis.metadata}} package contains a package-private 
{{PropertyDescriptor}} class, which currently implements 
{{org.opengis.parameter.ParameterDescriptor}}. The later is not really 
appropriate since metadata are not parameters. The 
{{org.opengis.feature.type.PropertyDescriptor}} interface would probably be 
more appropriate. However the feature packages are not yet part of GeoAPI 
standard (they are still in the pending part), while {{ParameterDescriptor}} is 
part of GeoAPI 3.0.0.

While the package-private class is not directly exposed to users, the interface 
implemented by this class is accessible by users. So the choice of 
{{ParameterDescriptor}} / {{PropertyDescriptor}} is significant. For now we 
stick on {{ParameterDescriptor}}, but a future Apache SIS version may need a 
transition path to features.
