 The Enhanced Citation model was presented in several venues and comments were consideredin considered in revising the model. This included:

• renaming a number of objects
• using the revised model for OrderRelations
• adding a hasConcept relationship to CustomItem
• adding a key property to CustomItem
• adding a key and a value property to  CustomValue
• setting CustomInstance and CustomValue to inherit from Identifiable

The models for custom metadata and controlled vocabularies have been entered into the Drupal siite (lion) as the CustomMetadata  package. We discussed adding a relationship to CustomInstance to Annotation but that has not yet been done.

We also discussed which parts of the openEHR blood pressure model ( https://omowizard.files.wordpress.com/2010/01/bp-mindmap.jpg ) might be described as custom metadata and which parts might be collected as data. An intended protocol description might be made using custom metadata with keys of CuffSize, Location, Method, MeanArterialPressureFormula etc. ass keys in an openEHR related CustomStructure. At the same time the data description group discussed how some of these same elements in other situations (e.g. where the protocol might vary for each patient) might be collected in event tagged DatumStructures.

As of 2015-05-29 that package includes the following classes

Work on representing these classes in Enterprise Architect is ongoing. The following diagrams do not yet show cardinalities.
