Run Jena including the DGGS jar for SF functions

Example docker command: docker run -p 3030:3030 -v <REPO_DIR>/dggs-jar/current:/fuseki-extra --name jena-dggs stain/jena-fuseki:4.0.0 NB: version 4.0.0 includes code to copy the jar files to the java classpath. Version 4.0.0 is not tagged with 'latest' on dockerhub, so it must be explicitly specified (or the jar files manually added to the classpath). You will need to obtain the fuseki password from the log output of docker. This can be automated with a shiro.ini file but has not been done for this repo.

Utilising functions

1. Create a dataset in Jena
2. Upload output/dataset_dggs_level_7.ttl to the dataset
3. Run queries in the following format:

PREFIX geo: <http://www.opengis.net/ont/geosparql#>

SELECT ?a ?geoma ?b ?geomb {
  ?a geo:hasGeometry / geo:asDGGS ?geoma .
  { SELECT ?b ?geomb {
  	?b geo:hasGeometry / geo:asDGGS ?geomb .
	}
  }
  FILTER (?a != ?b)
  FILTER(f:SFWithin(?geoma, ?geomb))
}
