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?
