The valid systems of classification of objects, materials, etc.

name (M, K: ndt_name)

The natural identifier for a classification system of objects, materials, substances, etc.


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 classification_system must provided by one ref_source. Inherited from reference_behavior.


description (O: ndt_comment)

A textual definition or description of the classification system.


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_class_alias (V: SET[0:?] activity_class_alias(classification_system)) (1132)

These are the aliases for activity class whose names are given context and meaning by this classification system. Each classification_system may defined one or more activity_class_alias.


classification_class (V: SET[0:?] classification_class(classification_system))

The set of classes which are part of this system. Each classification_system may contain one or more classification_class.


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

Indicates the data collections that include this instance of E and P data. Each classification_system 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 classification_system may datum for ranking one or more object_ranking. Inherited from object_of_interest.


equipment_class_alias (V: SET[0:?] equipment_class_alias(classification_system)) (1132)

These are the aliases for equipment class whose names are given context and meaning by this classification system. Each classification_system may defined one or more equipment_class_alias.


facility_class_alias (V: SET[0:?] facility_class_alias(classification_system)) (1132)

These are the aliases for facility class whose names are given context and meaning by this classification system. Each classification_system may define one or more facility_class_alias.


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

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


kind (O: ref_classification_system) (1132)

The kind or type of classification system. For example, if the classification systems was "lahee", then the kind might be "well". Each classification_system may be a kind of one ref_classification_system.


material_class_alias (V: SET[0:?] material_class_alias(classification_system)) (1132)

These are the aliases for material class whose names are given context and meaning by this classification system. Each classification_system may define one or more material_class_alias.


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 classification_system 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 classification_system 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 classification_system may version one ref_epicentre_version. Inherited from reference_behavior.


well_log_trace_class_alias (V: SET[0:?] well_log_trace_class_alias(classification_system)) (0705)

These are the aliases for well log trace class whose names are given context and meaning by this classification system. An example is the trace mnemonics provided by the service company. Each classification_system may define one or more well_log_trace_class_alias.
