It adds three elements for the classification of services: the spatial data service type according to the service types in annex D.3 of the INSPIRE metadata implementing rules; a keyword to identify the service type according to the ISO 19119 classification of geographic information services; and another keyword corresponding to the acronym of the OGC specification. For instance, in the case of a WMS, this method will fill: the spatial data service type element with the value “view”; and two keywords with the values “infoMapAccessService” (according to the ISO 19119 classification) and “WMS” (according to OGC classification). 4. DEPLOYMENT OF THE SERVICES CATALOG IN THE IDEE According to the architecture described in the previous section a first prototype of the IDEE Services Catalog has been developed (http://www.idee.es/IDEE-ServicesSearch/ ServicesSearch.html?locale=en). This prototype allows search and access to the description of services subscribed to the IDEE. Before this prototype, this description of services was updated manually within the IDEE services directory (http://www.idee.es/ show.do?to=pideep_catalogo.EN), a set of static Web pages to report the services offered by the IDEE member organisations. Additionally this prototype facilitates the online connection with OGC Web Map Services (WMS). Figure 3 shows a screenshot of the prototype. With respect to the construction of search requests, the query specification form (see left part of Figure 3) allows to establish different restriction criteria such as the geographic extension of the data provided by the service, the keywords, the service type, or the services provider. Once the results have been presented, the application enables the online edition of metadata items (see Figure 4). Besides, an important feature of the application is that it allows the automated generation of metadata for services compliant with OGC specifications by
means of their capabilities information. This functionality is provided when editing the information of a new service (see New Service button in Figure 4). Finally, it must be also noted that the online connection with the services returned by the catalog can be activated through the map icon in the list of results. For instance, Figure 3 (right part) shows how an OGC WMS Client is launched to add the new layers served by the WMS discovered through the catalog. Figure 3: Search criteria, result presentation and online connection with the services. Spatial Search Search by Service Type Search by Keywords Search by Provider Search by ISO 19119 Classification As regards the contents that are accessible through this prototype, we must mention that we have established a process to compile all the service URLs contained in the original static directory (335 services altogether) and apply the automatic method described in section 3.3 to convert the getCapabilities response into a metadata record compliant with INSPIRE and ISO 19115/19119 metadata models. Table 2 shows some statistics derived from this upload process. Table 2: Statistics about the upload of contents to the services catalog (Nr = number).
