- Field Detail
  - url
```
protected UriType url
```
    An absolute URI that is used to identify this research definition when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which at which an authoritative instance of this research definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the research definition is stored on different servers.
  - identifier
```
protected List<Identifier> identifier
```
    A formal identifier that is used to identify this research definition when it is represented in other formats, or referenced in a specification, model, design or an instance.
  - version
```
protected StringType version
```
    The identifier that is used to identify this version of the research definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the research definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active artifacts.
  - name
```

  - subject
```
protected DataType subject
```
    The intended subjects for the ResearchDefinition. If this element is not provided, a Patient subject is assumed, but the subject of the ResearchDefinition can be anything.
  - date
```
protected DateTimeType date
```
    The date (and optionally time) when the research definition was published. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the research definition changes.
  - publisher
```
protected StringType publisher
```
    The name of the organization or individual that published the research definition.
  - contact
