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