| Definitionskos:definition | This document describes an extension to the existing RDF Data Cube ontology to support specification of key metadata required to interpret spatio-temporal data. The RDF Data Cube defines CodedProperties, which relate to a reference system based on a list of terms, QB4ST provides generalized support for numeric and other ordered references systems, particularly Spatial Reference Systems and Temporal Reference Systems. Although RDF Data Cube supports AttributeProperties for metadata of individual observations, the requirement is to specify such metadata per property, rather than for each observation, and thus allow different properties to use different spatial or temporal reference systems. QB4ST also provides for such properties to be defined for a ComponentProperty, or defined at the time of referencing that ComponentProperty in a ComponentSpecification. QB4ST is thus aimed at improving the scope and consistency of dataset metadata, and hence discovery and interpretation of spatio-temporal data through its spatio-temporal reference system and bounding values. |
