Suppose I want to say something like:
The total rainfall in Edinburgh in 2006 was 600mm.
There are various ways to do it, but I'd probably go for something
like this in pseudo-RDF
Edinburgh hasMeasuredProperty _b
_b measureOf "Annual Rainfall"
_b period "2006"
_b rdf:value "600"
_b unit "mm"
(with some xsd data types added in).
The same general pattern applies to population of a country, or sales
of a product etc. I'd expect this pattern of data to appear very
frequently, but found it surprisingly difficult to find similar
examples on the web (other than in the RDF Primer! - and the
GoodRelations ontology does this kind of thing for
PriceSpecification). Can anyone suggest good ontologies/vocabularies
I should consider in areas like socio-economic data, physical
properties, weather, earth science that support this type of structure?
The NASA Jet Propulsion Lab SWEET ontologies seem relevant and are
very comprehensive, if rather sparsely documented (http://sweet.jpl.nasa.gov/ontology/
). Anyone used those in anger?
Thanks for any tips
Bill
