RE: space and time

Hi all,

You may find this of interest:

http://www.earthobservatory.eu/geospatial-extensions-for-rdf-and-sparql

This was some work done by the FP7 project TELEIOS looking at geospatial and temporal extensions to RDF/SPARQL (called stRDF and stSPARQL respectively). The spatial elements of this work did end up converging nicely with GeoSPARQL. The temporal aspects also look useful and interesting.

Subject: space and time


Hello,

When reading and talking about geographical Linked Data I sometimes come across the term 'spatiotemporal data', meaning that data are dependent on both space and time. I wonder if temporal aspects of data should be considered when we are thinking about how to express location data in the Semantic Web.

I understand that for many spatial data the temporal aspects are really important, but I think temporal aspects could be equally important to data about postage stamps or model trains or beer, or whichever other topics one can have data about. In all cases, I don't think it is necessary to think of special ways of expressing the time dimension in the data. It seems to me that general vocabularies and/or data types for expressing time should suffice. In other words, I think that time and space are orthogonal subjects and that vocabularies about space (location) can be kept separate from vocabularies about time (For normal everyday data, that is. Cosmological data are another matter).

What do you think about this?

Regards,
Frans
