Entity REFERENCE

POSC Specifications Version 2.2

Epicentre Logical Data Model

An abstract behavior that is used to provide the source of definition and population of an instance that has a standard or controlled population.

source (M: ref_source): The provider of this instance of reference information. If this instance is provided by POSC, then this attribute must be "POSC". Each reference_behavior must provided by one ref_source.
status (O: 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.
source_reference (O: 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 reference_behavior may documented by one ref_source_reference.
version (O: ref_epicentre_version) (0644): Describes the version of Epicentre when this status was assigned to this instance of reference behavior Each reference_behavior may version one ref_epicentre_version.
