Define a custom IIOMetadataFormat for ISO 19129 informations

                 Key: GEOTK-55
                 URL: http://jira.geotoolkit.org/browse/GEOTK-55
             Project: Geotoolkit
          Issue Type: Sub-task
          Components: Coverage
    Affects Versions: 3.05
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
             Fix For: 3.05

Transposing the full content of ISO 19115 into an {{IIOMetadataFormat}} would be too verbose. Only a subset is needed, and only some specialized classes (some generic metadata classes applies to both features and gridded data; we want the specialization for gridded data).

The ISO 19129 standard (_metadata for gridded imagery_) defines the metadata which are expected to be found with every Coverage. However the transposition in Java is not a "one to one" matching, because some informations required by ISO 19129 are provided by various {{ImageReader}} methods instead than {{IIOMetadata}} nodes. Consequently we need to etablish a mapping from ISO 10129 to Java API, and defines custom {{IIOMetadata}} node for the extra informations. This mapping is documented in the [org.geotoolkit.image.io.metadata|http://www.geotoolkit.org/apidocs/org/geotoolkit/image/io/metadata/package-summary.html#package_description] package description.

Once the mapping is etablished, we need to get in the details of a custom {{IIOMetadataFormat}}. This is documented in the [SpatialMetadataFormat|http://www.geotoolkit.org/apidocs/org/geotoolkit/image/io/metadata/SpatialMetadataFormat.html] class.
