  - masterSources
```
MasterSourceType[] masterSources
```
    Default:
    
    {}
- - sourceableParts
```
String[] sourceableParts
```
    Indicates that only some parts are sourceable. If this field is not set it's assumed that the whole field is sourceable.
    This applies only to lists or similar. For example, a list of identifiers where only the DOI identifiers are sourceable would set this field as {DOI}.
    
    Default:
    
    {}
- - overridable
```
boolean overridable
```
    Indicates that a field is initially filled from an external source, but it can be overwritten afterwards.
    E.g.: the names of IH collections.
    
    Default:
    
    false
