TimeMethodType

Describes the time method or time dimension of the data collection. This may cover specific timing issues such as when a data collection instrument is fielded (time of year, month, week, day), intended repetition, length of data collection period etc. In addition to the descriptive narrative supports the use of a brief term or external controlled vocabulary to classify the methodology used.

Allows for the specification of identifiers other than the specified DDI identification of the object. This may be a legacy ID from DDI-C, a system specific ID such as for a database or registry, or a non-DDI unique identifier. As the identifier is specific to a system the system must be identified with the UserID structure.

InheritanceAction

string

0..1

The attribute “action” is used for inheritance situations where there is an override at the local level (within a grouped StudyUnit) which is not available for further inheritance. There are three possible values for “action”: Add - A new identifiable object (an Identifiable, Versionable, or Maintainable element) is provided locally with a new identifier (one that is not inherited). All properties (elements and attributes contained in the object) of the object are as specified. If an object with an existing id is created, this is an error.; Update - An object is provided locally with the SAME id as the inherited object. For each type of property that is specified locally, a full set of those properties is specified for local use. These properties replace any properties of this type which were inherited. Unspecified properties are used as inherited.; Delete - An object is provided locally with the SAME id as the inherited object. All properties specified locally in this object will be deleted if their types and values match those inherited. Note that to completely delete an object at the local level, all properties of the inherited object must be listed.
