Query flow

Places API Search result items are Place object links, of type urn:nlp-types:place. Applications needing to discriminate the different kind of Search results are using either the category.id or the categories[].id attribute. GS7 Discover resultType response element can be used instead. More details are to be found in the Result Types page

Places API applications retrieving the additional details of Place Media types through the href attribute
can retrieve those details on GS7 using the Lookup service with the id response element returned by the Discover Service. Chapter Place Details describes how Place Media types attributes map to those of a GS7 Lookup result.
