Description / Abstract:
This Technical Report covers aspects of federations of Clinical
Document Registries (CDRs) including cases where the whole content
of a CDR has been replicated in another CDR of the same federation.
More specifically, the following aspects are covered.
a) Recommendations for the creation and management of
federations of CDRs and federation metadata.
b) Creation and management of federated replicas, including
specifications to create, remove and maintain federated replicas as
well as metadata for them.
c) Use cases of federations with query processing examples,
including various use cases of federations of CDRs, together with
examples of query processing policies to enhance the performance
and fault-tolerance. d) Processing of queries in the presence of
federations and replicas: the presence of federated replicas might
affect the semantics of both local and federated queries.
Informative examples to define exact behaviours of processing the
queries are given.
NOTE It is assumed that the problem of patient identification
has been solved in a way that is beyond the scope of this Technical
Report, such as IHE XCPD (Cross-Community Patient Discovery)
Profile. Some potential issues that will not be addressed in this
Technical Report include patient identity management, potential
limitations of registries due to jurisdictional policies or
requirements, and how replicates are handled.
