| Definitionskos:definition | The OGC service metadata document (sometimes also called capabilities document) is a key part in the service discovery. It describes the service and also the resources that the service expose. Resources are listed in the service metadata document inside a section named as Contents by OWS Common. There are two main limitations to the current Contents section approach: OWS Common offers flexibility for describing resources and it only proposes a very minimum set of metadata in figure 7 of OGC 06-121r9 called DatasetSummary that need to be sub-classed (i.e. extended) by any specific application. As a result, each standard proposes its own alternative for it. Integrated client developers need to implement them separately. If the number of resources is very large or the service is highly dynamic, the Contents section can be too long or useless and neither the service nor the client can handle it efficiently. This Engineering Report proposes a double solution to the Contents section of the service metadata documents: It proposes ways to encode the Contents section using the OWS Context encoding data types and it introduces the use OpenSearch as a way to request a subset of the resources that the service can provide access to. In that sense, the use of the OGC 10-032r8 OpenSearchGeo can provide the long time needed geospatial and temporal filter capabilities. |
