---|---|---|---|
1 | Hierarcy in Concept Domain | The hierarchy is missing in ConceptDomain class. There are two way in which this can be resolved: 1. Adding a recursive link to indicate the parent-child relationships 2. Adding a class called ConceptDomainAssociation between concepts domains. This will allow for finer typing of the relationships between concept domains, not just parent-child relationships. |
The following are enancements to the DSTU from a functional point of view. Some of them are present in the PIM but not in the DSTU, so they might be an oversight. Some operations too are also an obvious oversight, so they are not really enhancements.
Enhancements:
# | Description | Rationale | Resolution |
---|---|---|---|
1 | Binding to a single code. | A link between Code System Node and Binding allowing for the possibility to have the binding of a single code to a Usage Context or a Concept Domain. This is particularly useful in the cases where we have a value set that contains only one code and must have an OID such as in Anatomic Pathology for example. | |
2 | Change ValueSetContextBinding into Binding | The binding is not just done through just the value sets as mentioned - it can be done through a code. Furthermore, there are value sets that are not bound just to the UsageContext only but also to the Concept Domain (like in the MIF file). | |
3 | Change Cardinality in Binding from 1 to 0..1 | There are many templates generated by IHE. Binding takes places generally between a template and a value set (or a version of a value set). The concept domain is “forgotten”, or implicitly included in the template via the context it describes (in its title, or the subject described in the template, or in the text of the template). This means that in reality we only bind two entities (no Concept Domain). Replace 1 by 0 so that the binding between two entities possible. | |
4 | Assure multilingual representation | All the attributes that are indicating a representation of text such as the , "description", "provenanceDetails", "administrativeInfo" should be represented by a format supporting translations. | |
5 | Return Code System Version Details added. | This is an oversight. The Return Code System Details operation is present; it is a natural conclusion Return Code System Version Details was omitted. This is present in the PIM. | |
6 | List Code System Supplements | Again, this seems to be an oversight. | |
7 | Return Code System Supplement Details | Oversight. | |
8 | List Jurisdictional Domains | It is logical that in an environment with multiple juridictional domains, they should be listed. | |
9 | Return Jurisdictional Domain Details | Oversight. | |
10 | Add an operation which describes the service CTS2 itself. | An operation returning information about the CTS2 service. This is present in CTS, and in the PIM, so it could be an oversight. | |
11 | Add and id of an Association Type. | ||
12 | Conformance Criteria | The SFM is totally silent of what must be provided by an implementation allowing for declaring it conformant.
To the minimum extend, a single function listing all codesystems is enough. To the other extend all functions must be provided. The real necessity is something in the middle: The specific set of functions must be marked. Therefore, a classification and/or prioritization according the functions must be provided. A solution can be the declaration of a basic set of functions and appropriate options. E.g. the handling of value sets may be necessary for certain environments, but not really for all use cases. Therefore, all functions dealing with value sets can be assigned to "option 1". |
|
13 | Licensing Information | For a national use, the server must keep track of who is allowed to see which codesystem and the associated codes. E.g., only persons/institutions having purchased Snomed CT will get a result including Snomed CT. | |
14 | Addition of a new class EntityVersionCodeSystemVersionMembership | This new association class provides a more robust way of linking Entity Version to Code System versions. | |
15 | Additions to the Value Set Class to be able to support FHIR functionality |
