Change the thinking!
Many GI players were used to operate a “monopoly” structure, this needed to be changed to enable cross-provider business interoperability
2.2. Key adaption issues for SDI
Product types
INSPIRE offers with the Annex I-III definitions (INSPIRE) SDI wide known product types and (hopefully) unique references.
License types
Creative Commons offers multiple license types and an unique reference by URI
Key preconditions for a roaming operation model (SDI) are network wide known product types and in the case of data with IPR common license types.

…with multiple profiles
Currently the many different catalogue / discovery service specification are defined and partly in use.
Therefore a dimension in the analysis were different CS-W * specifications
For the meta data model the existing ISO 19915 / 19139 was used together with the INSPIRE IR.Some data field names needed to be adapted with a slightly different meaning (e.g. distributor vs. provider). Also the xlink arc role attributedwas used to assign the partnerships

Roaming RM Client Layers
Client side needs to know which home provider he has.Therefore the client side gets a RM Layer. This layer can be compared to the function of a GSM SIMcard.
For the find phase only the homeprovider (ID) needs to be stored and added to the request.
Depending on the CSW profile also additional logic needs to be executed in this Client RM/roaming layer.

Key results
BHT Berlin 23
Although the knowledge of the home provider needs to be added in all cases at the client side ( a la simcard ), the INSPIRE IR for Metadata and Discovery service can be used for the roaming model without any implementation modifications.

Another thesis focuses on the overall process model and in detail on the “agree” phase. Results expected in August 2009
Conclusion
Operation ModelsCentered Business Operation Model (a la e-commerce)Roaming Operation to introduce
seamless business and technical interoperability CompetitionBalancing of risks, investments and opportunities
Gap analysis with existing components in the “find” phasePositive, no specification/implementation change needed
Planed gap analysis for the “agree” and later “bind” phase
