A set of logical dependencies describing a typical activity. The dependencies are specified by the typical activities contained by the template and the template constraints.

name (M, K: ndt_name)

The name of the template.


described_activity (M, K: typical_activity(describing_template))

Defines the typical activity described by this template. Each activity_template must describe one typical_activity.


source (M, I: ref_source)

The provider of this instance of reference information. If this instance is provided by POSC, then this attribute must be "POSC". Each activity_template must provided by one ref_source. Inherited from reference_behavior.


description (O: ndt_comment)

A description of the template.


status (O, I: ndt_instance_status) (0644)

The status of this instance in the version of Epicentre running in a data store. This is an enumerated datatype for which the following are the possible values: current, provisional, deprecated. Current - use without restriction. Provisional - use with caution, this value is for comment and may not appear in future releases of Epicentre. Deprecated - avoid use if possible, it is planned to remove this value in the next major release of Epicentre. Inherited from reference_behavior.


activity_template_constraint (V: SET[0:?] activity_template_constraint(activity_template))

Gives the constraints that act on the typical activities contained by the activity template. Each activity_template may specify one or more activity_template_constraint.


contained_activity (O: SET[0:?] typical_activity(containing_template))

The typical activities that must occur for the parent typical activity to occur. Each activity_template may contain one or more typical_activity.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each activity_template may be a member of one or more data_collection. Inherited from e_and_p_data.


datum_for_ranking (I, V: SET[0:?] object_ranking(base_object))

Indicates that an object is being used as a basis for comparison with another object. Each activity_template may datum for ranking one or more object_ranking. Inherited from object_of_interest.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each activity_template may be depicted by one or more graphical_element. Inherited from e_and_p_data.


object_of_ranking (I, V: SET[0:?] object_ranking(ranked_object))

Indicates that an object is being classified in a rank order based on its characteristics. Each activity_template may object of ranking one or more object_ranking. Inherited from object_of_interest.


source_reference (O, I: ref_source_reference)

The reference used by source to provide the standard instance, such as Petroleum Industry Data Dictionary (PIDD), Websters Ninth New Collegiate Dictionary, etc. Each activity_template may documented by one ref_source_reference. Inherited from reference_behavior.


version (O, I: ref_epicentre_version) (0644)

Describes the version of Epicentre when this status was assigned to this instance of reference behavior Each activity_template may version one ref_epicentre_version. Inherited from reference_behavior.
