GeoSPARQL support

[MadsHolten]

Is it possible to set up a database that has both full text and GeoSPARQL support? Here is the assembler I tried. Unfortunately I had no luck with my test query 😒

@prefix fuseki:  <http://jena.apache.org/fuseki#> .
@prefix tdb:     <http://jena.hpl.hp.com/2008/tdb#> .
@prefix text:    <http://jena.apache.org/text#> .
@prefix skos:    <http://www.w3.org/2004/02/skos/core#> .
@prefix geosparql: <http://jena.apache.org/geosparql#> .

<#service> a fuseki:Service ;
    fuseki:name              "ds" ;   # http://host:port/ds
    fuseki:serviceQuery      "sparql" ;    # SPARQL query service
    fuseki:serviceUpdate     "update" ;    # SPARQL update service
    fuseki:serviceReadWriteGraphStore "data" ;     # SPARQL Graph store protocol
    #fuseki:serviceReadGraphStore    "data" ;     # SPARQL Graph store protocol (read only)
    fuseki:endpoint [ fuseki:operation fuseki:shacl ; fuseki:name "shacl" ] ;
    fuseki:dataset           <#text_ds> ;
#    fuseki:dataset           <#tdb> ;
    .

<#text_ds> a text:TextDataset , geosparql:geosparqlDataset ;
    text:dataset <#tdb> ;
    text:index <#lucene> ;
    geosparql:dataset <#tdb> ;
    geosparql:spatialIndexFile     "/fuseki-base/databases/tdb/spatial.index";
    .

<#tdb> a tdb:DatasetTDB ;
    tdb:location "/fuseki-base/databases/tdb" ;
    tdb:unionDefaultGraph true ;
    .

<#lucene> a text:TextIndexLucene ;
    text:directory <file:/fuseki-base/databases/lucene> ;
    text:storeValues true ;
    text:entityMap <#entity-map> ;
    .

<#entity-map> a text:EntityMap ;
    text:entityField "uri" ;
    text:graphField "graph" ; ## enable graph-specific indexing
    text:defaultField "text" ; ## Must be defined in the text:map
    text:uidField "uid" ;
    text:langField "lang" ;
    text:map (
         [ text:field "text" ; text:predicate skos:prefLabel ]
         [ text:field "text" ; text:predicate skos:altLabel ]
         [ text:field "text" ; text:predicate skos:hiddenLabel ]
         [ text:field "text" ; text:predicate skos:notation ]
         )
    .

And my test query:

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

SELECT ?point
WHERE {
    BIND("POLYGON ((-64.8 32.3, -65.5 18.3, -80.3 25.2, -64.8 32.3))"^^geo:wktLiteral AS ?polygon)
    VALUES ?point { "POINT (-70.268555 25.522615)"^^geo:wktLiteral "POINT (-60.996094 24.846565)"^^geo:wktLiteral }
    FILTER(geof:sfWithin(?point, ?polygon))
}

I got it to work by simply adding the geosparql jar to the jena-fuseki dir. Same config file and all (https://github.com/SemanticComputing/fuseki-docker/blob/master/assembler.ttl). I was quite surprised to find that it was so simple.

So a simple Dockerfile like this will do the job:

FROM secoresearch/fuseki:5.2.0

USER root
RUN wget https://repo1.maven.org/maven2/org/apache/jena/jena-fuseki-geosparql/5.2.0/jena-fuseki-geosparql-5.2.0.jar -O /jena-fuseki/fuseki-geosparql.jar

To give you the full picture, here is that config file I am using with basically no additions
