Hi,

we've been experimenting with running rdf-delta in a Docker container, which 
ran fine until commit 
[bb2f9d2f5ea61fed37d5621ec3147dd01e9b0d5b](https://github.com/afs/rdf-delta/commit/bb2f9d2f5ea61fed37d5621ec3147dd01e9b0d5b)
 , after which the 2.0.0-SNAPSHOT version was reverted to 1.3.0-SNAPSHOT.

As soon as we move past that, we're getting errors about a missing 
librocksdbjni jar when running the rdf-delta server (this is a separate issue I 
suppose).

So in 
https://github.com/Kurrawong/rdf-delta-container-image/blob/enable-geosparql/Dockerfile
 we build the version using the commit mentioned above, which runs fine.

However, when I try to enable GeoSPARQL by including a [dependency 
patch](https://github.com/Kurrawong/rdf-delta-container-image/blob/enable-geosparql/patches/enable-geosparql.diff#L54-L60)
 for rdf-delta-fuseki-server, the images still build just fine, it just doesn't 
actually seem to enable GeoSPARQL. (note that this approach does work with the 
full version of fuseki, as we do 
[here](https://github.com/Kurrawong/fuseki-container-image)).

With the rdf-delta version, the fuseki server complains with the following 
error message:

> the (group) Assembler 
> org.apache.jena.assembler.assemblers.AssemblerGroup$PlainAssemblerGroup@2e2f720
>  cannot construct the object :spatial_dataset because it does not have an 
> implementation for the objects's most specific type geosparql:geosparqlDataset

So I'm wondering if my [database 
config](https://github.com/Kurrawong/rdf-delta-container-image/blob/enable-geosparql/config.ttl)
 is wrong, or if the rdf-delta-fuseki-server package simply does not support 
GeoSPARQL?

Thanks in advance for any insights into this!

best regards,
Tom
