Andy Seaborne commented on JENA-2254:
-------------------------------------
It would be good to handled other lat/long vocabularies.
I don't understand what's going on. {{convertGeoPredicates(Dataset dataset,
boolean)}} returns dataset (an in-memory copy with converted predicates) but it
is not used.
So the handling of W3C WGS84 must be somewhere else.
There are some places that check for them and issue warnings without actually
doing anything with them.
{{SpatialIndex}} maybe but there are other places using the vocabulary.
> Custom long/lat spatial predicate pairs for geosparql

> Key: JENA-2254
> URL: https://issues.apache.org/jira/browse/JENA-2254
> Project: Apache Jena
> Issue Type: New Feature
> Components: GeoSPARQL
> Reporter: Øyvind Gjesdal
> Priority: Minor
>
> At the moment geosparql supports many of the old jena-spatial functions.
> The jena-spatial module also had custom long/lat and also custom WKT
> predicates. At the moment we still use the old jena spatial module, but when
> the assembler file for geosparql is ready in jena 4.4, I think we can switch.
> Writing an assembler which uses both jena-text and geosparql is how we've
> mostly used the jena-spatial module.
> One remaining issue we have in our data (from external datasets), is custom
> long/lat predicates. Bringing support for these would be nice. I tried to
> look at the code, and it seems the geo:long,geo:lat are translated in
> https://github.com/apache/jena/blob/main/jena-geosparql/src/main/java/org/apache/jena/geosparql/configuration/GeoSPARQLOperations.java#L749
> Would it work/be enough to look up/reuse the jena-spatial assembler
> predicates, and also loop through these pairs in the
> *convertGeoPredicates(Dataset dataset, boolean isRemoveGeoPredicate)* or
> should there be a new method to convert custom predicates?
> This is how the old assembler looks, from the jena-site:
>
> {code:java}
> # custom geo predicates for 1) Latitude/Longitude Format
> spatial:hasSpatialPredicatePairs (
> [ spatial:latitude :latitude_1 ; spatial:longitude :longitude_1 ]
> [ spatial:latitude :latitude_2 ; spatial:longitude :longitude_2 ]
> ) ; {code}
