Information Models
The core MDS and the Modules have been translated into FHIR logical models. This representation as logical models does not take into account any mapping to FHIR.
Each logical model integrates information from the MDS:
| NFDI4Health Element | Definition of NFDI4Health Element | FHIR Logical Model Element | Required? |
|---|---|---|---|
| Item | Name of the Item | ElementDefinition.path | Required |
| No | Number of the Version | ElementDefinition.mapping.identity and ElementDefinition.mapping.map | Required |
| Data element heading / Short name to display (display_name) | Display name | ElementDefinition.short | Required |
| Data element description (description) | Description | ElementDefinition.description | Required |
| Cardinality | Cardinality | ElementDefinition.min and ElementDefinition.max | Required |
| Data Type | Data Type | ElementDefinition.type | Required |
| Display information? (Data capturing) | Should the information be displayed during data capture? | ElementDefinition.comment | Required |
| Display information? (Data visualization) | Should the information be displayed during data visualization? | ElementDefinition.comment | Required |
| Source of the property and/or allowed values | Where does the element or the allowed values come from? | currently as "ElementDefinition.comment" | Required |
| Allowed Values | Which values are acceptable? | ElementDefinition.binding.strength, ElementDefinition.binding.description and ElementDefinition.binding.valueSet | No, only where relevant/applicable |
| Conditional Cardinality (in field Cardinality) | When is a particular element triggered? | ElementDefinition.comment and FHIRPath | No, only where relevant/applicable |
| Data element additional information - general information (additional_information) | Additional information | ElementDefinition.comment | No, only where relevant/applicable |
| Data element additional information - short input help (short_input_help) | Helping information in data entry mask | ElementDefinition.comment | No, only where relevant/applicable |
| Data element additional information - input example (input_example) | Example data helping in data entry mask | ElementDefinition.example.label (mostly set to "General") and ElementDefinition.example.value[x] | No, only where relevant/applicable |
