Init1pm16.1 - 21090 Datatype Support - Import Datatypes
Use Case Number |
Init1pm16.1 |
Brief Description |
ISO 21090 defines a set of datatypes for reuse within healthcare applications. When developing a new information model for sharing healthcare data, the first step is to choose a set of datatypes to "import" or "derive from". Being able to select which datatypes you will reuse forms the basis of interoperating at the basic (datatype) level. |
Actor(s) for this particular use case |
Information Modeler |
Pre-condition |
ISO 21090 datatypes are registered in a metadata repository |
Post condition |
ISO 21090 datatypes are available within the Information Modeler's UML modeling tool. This means that that the ISO 21090 datatypes have the following properties in the modeling tool:
|
Steps to take |
|
Alternate Flow |
An alternate flow to this use case is that the Information Modeler imports datatypes from another information model (which may be localized rather than the vanilla ISO 21090 datatypes). This is a highly desirable flow because it will greatly speed the adoption of ISO 21090 datatypes and interoperability. |
Priority |
High |

|
Fit criterion/Acceptance Criterion |
The Information Modeler must be able to import datatypes into his UML modeling tool, these must be represented fully (so that they can be localized), and they must be able to be made the types of attributes within the information model itself. |
Init1pm16.2 - 21090 Datatype Support - Localize Datatypes
Use Case Number |
Init1pm16.2 |
Brief Description |
A key aspect of ISO 21090 datatypes is that they can be localized for use within a specific information model. The datatypes themselves define a number of optional attributes and associations, and the actual behavior of the datatypes in some cases can be modified. Specifically, ISO 21090 has two types of conformance: Direct Conformance and Indirect Conformance. Indirect conformance is defined as:
|
Actor(s) for this particular use case |
Information Modeler |
Pre-condition |
ISO 21090 datatypes have been imported in the model (see use Init1pm16.1 above) |
Post condition |
The ISO 21090 datatypes have been localized within the Information Modeler's information model (in UML). By value of having imported the datatypes from the metadata repository and following ONLY the below steps, the resulting localized ISO 21090 datatypes are in Indirect Conformance with the specification. |
Steps to take |
|
Alternate Flow |
The steps above do not preclude the creation of ECCF documents or other mappings/specification documents. However, this use case does ease the creation of such documents because the ISO 21090 datatypes are derived directly from the metadata repository (meaning they have the appropriate level of specification/documentation already) and the localizations are made in conformance with the metadata repository conventions. |

|
Fit criterion/Acceptance Criterion |
The datatatypes should be localized using the conventions of the UML modeling tool. That is, it is highly desirable that user actions be constrained by what will be conformant when the localized datatypes are registered and shared. |
