This is a requirement for semantic annotation of Archetyped data for use in semantic web applications. Onological annotation is an important mechanism for discovery and automated inferencing that is commonly used in research. One practical example would be to add Gene and Protein sequence URIs to data items (CLUSTER or ELEMENT) or higher up the Archetype structure based on Instance data, for example in the case of certain lab results corresponding UniProt database URI can be saved together with instance data. This would result in consistent annotation and semantic querying of Archetype based repositories using general purpose semantic web tools. It would be desirable to follow RDF approach; e.g.
subject: unique runtime archetype path,
predicate: URI (alternatively can be DV_CODED__TEXT or some openEHR enumeration such as MIRIAM annotation types),
object: URI or CODE_PHRASE (that will have external terminology link)
