| This service returns all instances that located within a specified region, e.g. that defined by a graticule. The idea here is that an arbitrary region could be defined by dragging a graticule across a map visualization. The invocation of the query service will then aim to return all instances that fall within that region, i.e. are located in that region. Since only instances of spatial things can participate in the located in relationship, only instances of spatial things can be return by this query service. Note that this query could be combined with other query services to return all instances of a specified type, e.g. all refugee camps within a specified region. Note that because of the transitive composition of the 'isLocatedIn' relationship other regions may be returned by this query service. For example, if the specified region is Afghanistan, then other types of region, e.g. provinces and districts, could be returned by this service. The input to this service is a spatial region, the output is a list of individuals. |
