GeoAPI provides resource bundles for metadata elements:
geoapi/src/main/resources/org/opengis/metadata/CodeLists.properties: human-readable labels for code list elements.
* geoapi/src/main/resources/org/opengis/metadata/Descriptions.properties: short descriptions of metadata elements (including code list elements).
Languages currently available are English and French, but the later is quite incomplete. More French translations can be found there:
We should integrate those translations, if we are allowed to.
