Cataloguing GI Functions provided by Non Web Services Software Resources Within IGN
Résumé
Numerous software resources are available within IGN, the French National Mapping Agency, to manipulate geographical data. These are commercial off-the-shelves software or ad hoc tools developed within IGN. Sharing these resources and information about them is necessary but is still too difficult. This paper presents our approach to catalogue resources available within IGN to manipulate geodata. We extend upon OWLS metadata model for Web Services to propose a metadata model that describes services provided by any software resource that is not a Web Service. A crucial aspect of this extension is the modification of the metadata entity called 'grounding'. The grounding of a service in OWLS is mostly the description of the sequence of XML messages that must be send to or received from the Web Service URL to achieve this service. In our context, a service 'grounding' is described as a sequence of more generic steps. Besides, it is necessary to adapt a grounding description to the user context.
