8. What we suggest? Centralized scenarios Less effort for the local level implementers The effort is moved to the RoR SearchExtensions

9. Next steps Set up a testbed for the 2 different use cases (search and extension) Prerequisites The current production instance of the INSPIRE registry service will be used Create one or more sandbox instances as an example of local level registry Search use case Indexing system configuration Agree on a common exchange format for the indexes (first draft to be proposed by JRC) Implement different options for index data transfer: 1) Push 2) index harvesting 3) index creation from harvested data Implement query interface Extension use case DB / data model for RoR Agree on a common exchange format for extensions (first draft to be proposed by JRC) Implement different options for extension data transfer: 1) Push 2) harvesting Data access interface
