Ok, I did some tests, and good news, app-schema-resolver seems the way to
go.
My idea now is to:
- add a dependency in gt-xml to gt-app-schema-resolver (a little bit weird
since gt-xml is core, and app-schema-resolver an extension, maybe
AppSchemaResolver should find a better home in a core module in the near
future)
- update org.geotools.xml.schema.SchemaFactory to use AppSchemaResolver
with classpath resolving and AppSchemaCache fallback with automatic download
- configure AppSchemaCache to use a folder found in schema.factory.cache
(this allows to create xsd caches on geoserver data_dir for example) system
property, if defined, or a temporary folder if not
- as a side effect xsd already available in geotools jars (such as
gt-xsd-core) will be immediately available to SchemaFactory locally
(included the one that was slowing down WMS cascading with inspire)
I did some test on master and everything seems to work like a charm. Can I
proceed with the pull request?
Thanks.
