Use Case Number | Init1pm11.2 |
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: The second step in working with a DAM is to refine it by identifying those classes, attributes, and associations that will not be reused. These should be marked up in the UML in some fashion as to indicate that they are not included in the information model. |
Actor(s) for this particular use case | Information Modeler |
Pre-condition | ISO 21090 datatypes have The DAM has been imported in the model (see use Init1pm16Init1pm11.1 above) |
Post condition | The ISO 21090 datatypes have been localized DAM has been refined 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 DAM is derived directly from the metadata repository (meaning they have it has the appropriate level of specification/documentation already) and the localizations refinements are made in conformance with the metadata repository conventions. |

Fit criterion/Acceptance Criterion | The datatatypes DAM 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 DAM is registered and shared. |

Derive Implementation Model
Use Case Number | Init1pm11.3 |
Brief Description In addition to providing a platform independent UML representation of healthcare datatypes, ISO 21090 defines an XML binding of those datatypes to be used when exchanging data between physical systems. Specifically, ISO 21090 requires the following for Indirect Conformance: Specify whether the XML representation described herein is used when the datatypes are represented in XML, or optionally to provide an alternative namespace for the XML representationThis use case describes the generation of an XML Mapping including an XML Schema | The third step in working with a DAM is to derive an implementation model based upon the DAM. The Information Modeler imports the refined DAM into his implementation model package and adds the necessary specificity such that it can be implemented. |
Actor(s) for this particular use case | Information Modeler |
Pre-condition | The ISO 21090 datatypes have been localized DAM has been refined in the Information Modelers UML modeling tool using the necessary metadata repository conventions. |
Post condition | An XML Schema and mapping guide are generatedimplementation model is created that has the necessary information for semantic annotation and registration, as well as the necessary information for generating a DAM mapping document. |
Steps to take |
|
Alternate Flow | The Information Modeler manually creates XML Schema, a mapping document, and annotates the model accordingly with the UML-to-XML Schema mapping informationupdates an existing implementation model that has previously been derived from a DAM. |

Init1pm11.4 - Generate Mapping Document
Use Case Number | Init1pm11.4 |
Brief Description | caBIG compability and ECCF require that semantic metadata be registered and advertised in order to facilitate interoperability. This use case describes the process by which an Information Modeler takes his localized, XML Schema mapped model to the centralized metadata repository The next step in the DAM process is to create a document that describes the changes and additions to the DAM. This includes name changes, excluded classes/attributes, and added classes/attributes. |
Actor(s) for this particular use case | Information Modeler |
Pre-condition | A localized ISO 21090 DAM-derived implementation model exists in the Information Modeler's UML modeling tool with all required annotations to be registered, including XML Mappingsgenerate a mapping document. |
Post condition | The information model is registered and available in the metadata repository A mapping document is generated. |
Steps to take |
|
Alternate Flow | None. |
Priority | High |
Associated Links | Init1pm16 - 21090 Datatype Support Init1pm11 - LS DAM refinement and utilization |
Fit criterion/Acceptance Criterion | None. The entire information model should be registered, including the localized ISO 21090 datatypes and XML Schema mappings. It should be obvious from which vanilla ISO 21090 datatypes the localized data are derived. |

Register DAM-derived Implementation Model
Use Case Number | Init1pm11.5 | |
Brief Description | The true test of whether the semantic infrastructure is handling ISO 21090 requirements is that it is possible to: final step in the DAM process is to register a DAM-derived implementation model. This use case is important because it is important to share in the metadata repository the relationship of the implementation model to the original DAM, and, if possible, to the derived DAM. | |
Actor(s) for this particular use case | System Architect | Information Modeler |
Pre-condition | A refined DAM and completed DAM-derived implementation model exists in the Information Modelers UML tool. Two or more systems have correctly imported, localized, generated XML Schema, and registered information models with ISO 21090 datatypes. Furthermore, these information models are implemented by real systems with ECCF compliant APIs. | |
Post condition | Touch points are discovered and data is successfully exchanged The refined DAM and implementation model are registered in the metadata repository. | |
Steps to take |
| |
Alternate Flow | None. | |
Priority | High | |
Associated Links | Init1pm16 - 21090 Datatype Support Init1pm11 - LS DAM refinement and utilization | |
Fit criterion/Acceptance Criterion | The documentation and semantic metadata should be sufficient information to determine the mechanism by which data can be exchanged between systemsrelationships between the original DAM, the derived DAM, and the implementation model are captured in the metadata repository. |
