DBpedia defines datatypes for units and dimensions.

The page below shows a "hierarchy" of datatypes, although there's no such thing as subClassOf for datatypes (see #22). In PropertyMapping.unit you can specify:

  • Either a super-datatype, in which case the templateProperty is expected to have an explicit unit. Eg in [Mapping_pt:Info/Futebolista]:


Property Mapping (help)
template property altura
ontology property height
unitLength
  • Or a specific datatype, in which case the templateProperty carries a pure number, which is interpreted as the provided unit. Eg in [Mapping_en:Infobox_street]:


Property Mapping (help)
template property length_ft
ontology property length
unitfoot


In both cases:
