Add timestamps to TTL dumps #69

Open hannahbast opened 10 months ago

hannahbast commented 10 months ago

@lehmann-4178656ch @patrickbr The last three example queries on https://wiki.openstreetmap.org/wiki/SPARQL_vs_Overpass_QL_examples involve timestamp information. Is this information contained in the PBF files (at least in planet-latest.osm.obf)? If yes, I would suggest adding the corresponding triples to our TTL dump(s).

Do you agree?

I think that's a great idea. @lehmann-4178656ch already started to implement this in https://github.com/ad-freiburg/osm2rdf/tree/ohm-support
