Issue

Description of relationship between DATAVALUE.type, typeId, templateId, profileId, interactionId is missing. Also the definition of profileI and InteractionId implies that these only convey the constraints on the information to be conveyed -- whereas they also imply sendre and receiver responsibilities -- this inconsistency should be addressed.

Recommendation(s)

It is recomended that the text for

RIM Recommendation(s)

Add a paragraph discussing the relationship between the attributes into the definition of typeId, and reference it from the other sections.

Vocabulary Recommendation(s)

none

Rationale

There is a need for greater clarity


Recommended Action Items

  • Implement the proposed solution


Discussion

The following are the existing definitions taken from the 2006 normative editation

3.5.7.1 Message.profileId:: LIST<II> (0..*) Definition:The message profile identifier allows a given implementation to explicitly state how it varies from the standard message definition.

When multiple profiles are specified, the message instance must be valid against all of them. However, a receiver may choose to validate against only the first one recognized. For this reason, 'preferred' or more-rigorous profiles should be listed first.


3.5.8.6 Transmission.interactionId:: II (0..1) Definition:The interaction identifier is a reference to the unique information interchange derived from the V3 MDF for specifying a message.

Note: This attribute is also present in the sibling class, Batch. This change was made rather than moving this attribute to their common ancestor class, Transmission. This decision was taken because we do not have all the methodology and backwards compatibility issues worked out. Once we have established our backwards compatibility, we should promote this attribute to the parent. The problem is the sequencing of attributes within the HDF and their impact on the ITSs.


3.4.1.3 InfrastructureRoot.typeId:: II (0..1) Definition:When valued in an instance, this attribute signals the imposition of constraints defined in an HL7-specified message type. This might be a common type (also known as CMET in the messaging communication environment), or content included within a wrapper. The value of this attribute provides a unique identifier for the type in question.

3.4.1.4 InfrastructureRoot.templateId:: LIST<II> (0..*)

Definition:When valued in an instance, this attribute signals the imposition of a set of template-defined constraints. The value of this attribute provides a unique identifier for the templates in question.

1.11.1 Data Type : TYPE

Definition: Represents the fact that every data value implicitly carries information about its own data type. Thus, given a data value one can inquire about its data type.

invariant(ANY x) {

  x.dataType.nonNull;
