| Zusammenfassung |
| SeaDataNet is an EU funded project aiming to create and operate a
pan-European, marine data infrastructure for managing the large and diverse
datasets (i.e. temperature, salinity current, sea level, chemical, physical
and biological properties) collected by the oceanographic fleets and the new
automatic observation systems. In order to make the SeaDataNet system
compliant with the INSPIRE Implementing Rules for discovery service, an ISO
19139 encoding of the SeaDataNet Common Data Index (CDI) metadata model was
defined. Moreover, the problem of heterogeneous data sources has been
addressed. In fact, a widely used system of SeaDataNet partners and
oceanographic-marine community is THREDDS/OPeNDAP; this raises up the
problem of federating into SeaDataNet framework THREDDS/OPeNDAP systems as
well. In this paper we describe an interoperability framework to access
resources (i.e. data and services) that are available through CDI and
THREDDS/OPeNDAP services. The proposed solution implements a common catalog
interface to discover and access the two heterogeneous resources in a common
way. This catalog service is fully distributed and implements international
standards as far as geospatial information discovery and query are
concerned. The developed solution is called GI-cat and was experimented in
the framework of the SeaDataNet European project. |
