Automatically document metadata for geographic services¶
As well as being essential for compliance with the INSPIRE directive, geographic web services are an indisputable added value in the process of enhancing and developing uses for geographic information.
Isogeoautomates the filling-in of service metadata from the simple URL address of a service:
- on the one hand, metadata entry and updating time is greatly reduced;
- secondly, the quality of documentation is improved, as is the user experience of consultation applications, first and foremost OpenCatalog.
Lastly, the information entered enriches the search:
- retrieve data from a service and vice versa;
- search for layers in a service.
This functional brick takes into account the standardized services of theOGC(Open Geospatial Consortium) as well as ESRI's own specific formats.
General principle¶
Generally speaking, the procedure can be broken down into 2 steps, detailed in the sub-chapters : 1. Automatically list the layers of a geographic service based on its base URL; 2. Associate each layer served with a data item inventoried in Isogeo.
