The document discusses linked base registries as an enabler for eGovernment in Flanders. It outlines Flanders' strategy called OSLO2 which aims to improve interoperability and reuse of base registry data through semantic agreements and linked open data principles. A key example is Flanders' address registry which contains over 4 million addresses and is available as linked open data through APIs. The approach seeks to facilitate improved public services by making government data more interoperable and accessible.

13. BASE REGISTRIES
Base Registries Concept
• Base registries are part of a semantic
coherent system (OSLO) of uniformly
identified base objects and relations.
• A base registry should reuse the
identifiers of the base objects of other
base registries.
• The base registries are obliged to
maintain the Life-cycle and History of
the base objects.

15. HYPOTHESIS
The design principles of the
Semantic Web CAN facilitate
interoperability within the public
sector
Decisions in relation to semantic
agreements must be traceable,
transparent and consistent at all
levels.
