Content Registry- Basic Concept
Transfer of metadata from services (repository) to CR
Put it into RDF, send to CR when requested
– RDF generated on the fly
– RDF pre-saved
(Scenario for most of the services)
Send it as objects via SOAP calls
– requires an API wrapper at the service side
(Scenario for CIRCA)

DC and Environmental Information
Environmental information resources become increasingly available through the internet.
EIONET is adopting DCES for description and discovery of its information resources by:
•extending DCES and DCQ with the ‘missing’ elements and qualifiers, while fitting them with their domain specific themes and
•defining an individual namespace for each data element.
ReportNet is the approach to integrate services based on DC.

The End...

...is just the beginning

DC: Environment InterestGroup
...
The Idea for such open forum might be:
• to collect information on usage of DC in the environmental domain,
• to give guidance of the use of DC in the environmental domain,
• to install a forum for discussion of issues concerning DC with respect to environmental information resources,
• to develop an application profile for the environmental domain, based on DC
• to establish the representation of the environmental domain and their issues in DCMI (and vice versa?)
Matthias Menger, DC-2001, Tokyo / Japan European Environment Agency
DC:Environment InterestGroup
...
• to promote interoperability within the environmental
domain through the use of dublin core• to liaise with other communities in the environmental
domain that do not use DC for their resources• explore the possibilities to set up a DCMI Working
Group for Environment
