Besides conducting your own search entry 2.1.4 Where can you find metadata? a register can be used through the ‘backdoor’. Based on standard searching protocols, it is possible to consult the central catalogue of a register, such as the nationaal georegister (NGR) via the search client of another (web) application. It is even intended that the use of these registers might run via (web) applications of others. These may be applications or websites related to specific communities, generic search engines such as Google, but also heavy GIS clients.
The EduGIS-portaal has developed a search client which searches data services in the national geo-register based on their metadata. This mechanism functions as follows. The student searches via the search engine on the searching page of the EduGIS-portaal for web mapping services, which are offered and conform to the OGC WMS standard. The question is put to the national geo register using an agreed (standard) search protocol. The national geo-register gives the results of the search command to the EduGIS-portaal search client which displays the results to the students in the form, and appearance that they use themselves. If the student finds a mapping service (WMS), it can be displayed by the EduGIS-portaal map viewer. All of this is handled using agreed metadata and catalogue standards. The search client is made available by the national geo register as an API, so it is easy and fast for others to use it as well.
