Provide standard SPARQL endpoint response types #9

Closed rob-metalinkage closed 6 years ago

rob-metalinkage commented 6 years ago

nb - sparql result sets require more coding unless libraries do this out of the box, but SPARQL construct returns a graph - so probably easier.

Done, see http://gnafld.net/sparql

rob-metalinkage commented 6 years ago

Not functioning as a SPARQL endpoint AFAICT:

test:

curl -G http://gnafld.net/sparql --data-urlencode query="select distinct ?type where {?thing a ?type }limit 20"

curl -G http://defs-dev.opengis.net:8080/rdf4j-server/repositories/ogc-na --data-urlencode query="select distinct ?type where {?thing a ?type }limit 20"

Underlying API returning as expected, for above:

1 http://gnafld.net/def/gnaf#FirstStreetNumber
2 http://gnafld.net/def/gnaf#FrontageCentreSetbackGeocode
3 http://gnafld.net/def/gnaf#UnknownVillaAddress
4 http://gnafld.net/def/gnaf#Address
5 http://gnafld.net/def/gnaf#RangedAddressAlias
6 http://gnafld.net/def/gnaf#BuildingCentroidGeocode
7 http://gnafld.net/def/gnaf#ContributorDefinedAlias
8 http://gnafld.net/def/gnaf#StreetLocalityGeocode
9 http://gnafld.net/def/gnaf#PropertyCentroidManualGeocode
10 http://gnafld.net/def/gnaf#SynonymAlias
11 http://gnafld.net/def/gnaf#GapGeocode
12 http://gnafld.net/def/gnaf#FlatNumberNoFirstSuffixCorrelationAlias
13 http://gnafld.net/def/gnaf#LocalityGeocode
14 http://gnafld.net/def/gnaf#FlatNumber
15 http://gnafld.net/def/gnaf#LastStreetNumber
16 http://gnafld.net/def/gnaf#LevelDuplicationAlias
17 http://gnafld.net/def/gnaf#FlatPrefixSuffixDeduplicationAlias
18 http://gnafld.net/def/gnaf#UnknownCottageAddress
19 http://gnafld.net/def/gnaf#UnknownRoadsideMailBoxAddress
20 http://gnafld.net/def/gnaf#LevelNumber

but GNAF API seems to be timing out. Will investigate

Yeah, the underlying POST to the SPARQL endpoint timed out and I haven't written an elegant failure handler yet.
