Hi,
Sorry for the cross posting but this subject touches GeoServer and GeoTools.
I'm just thinking loud here about how app-schema could be extended to allow several mappings for the same target element in different sores.
Right now with app-schema is not possible to create more that one mapping per target element in the global application, even in different stores.
I can see three main reasons for this:
- is not possible to have several workspaces with the same name space
- the layer name (feature type name) needs to be the same as the target element and unique globally
- the lookup for the feature chaining is made globally (i.e. all the data stores are used)
Assuming that we manage to allow several workspaces to use the same name space (I need to investigate this).
It should be possible to allow the same target element to be mapped in different stores. To make this happen it should be possible to have a layer with a name different from the mapped target element and the global logic implemented in the data access registry needs also to be updated to search first in the store and after globally:
https://github.com/geotools/geotools/blob/master/modules/extension/app-schema/app-schema/src/main/java/org/geotools/data/complex/DataAccessRegistry.java
Thoughts about this ? Is there any other reason from those above to limit one mapping per target element ?
Regards,
Nuno Oliveira
