- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- source (O, I: ndt_identifier) (C126)
- The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
- source_content (O, I: ndt_identifier) (C126)
- This is the original source of the data. This is the person, company or application that defined or specified the data (content) for this instance and is considered to be responsible for it. For example, POSC, EPSG, API, ISO, etc. This may be the same as or different from the provider of the instance (e.g., POSC). Inherited from ref_aliasable_data.
- source_reference (O, I: ndt_comment) (C042, C126)
- The reference used by source to provide the standard instance, such as Petroleum Industry Data Dictionary (PIDD), Websters Ninth New Collegiate Dictionary, etc. Inherited from ref_aliasable_data.
- status (O, I: ndt_instance_status) (C042)
- 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 ref_aliasable_data.
- sub_unit_per_unit (O: ndt_pint2)
- The number of sub units that are equivalent to the unit. This is undefined (null) if there is no sub unit defined.
- code_alias (I, V: SET[0:?] code_alias(aliased_object)) (C029)
- Indicates the various identifiers by which this data is known. Each ref_currency_unit may be known by one or more code_alias. Inherited from ref_aliasable_data.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each ref_currency_unit may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each ref_currency_unit may be included in one or more document_information_content. Inherited from e_and_p_data.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each ref_currency_unit may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- larger_unit (V: SET[0:1] ref_currency_unit(smaller_unit)) (C151)
- Defines the larger currency unit of which this unit is an integral subunit. Each ref_currency_unit may be a sub unit of one ref_currency_unit.
- naming_system (O, I: naming_system(ref_aliasable_data)) (C028)
- The naming system in which the identifier is specified and determined to be unique. Each ref_currency_unit may have name specified by one naming_system. Inherited from ref_aliasable_data.
- property_kind (V: SET[0:?] property_kind(money_constraint)) (C124)
- These are the property kinds which are constrained to use this unit if instantiated using MONEY a data type. Each ref_currency_unit may constrain one or more property_kind.
- smaller_unit (O: ref_currency_unit(larger_unit))
- This defines the smaller currency unit which evenly divides into this unit. Each ref_currency_unit may have a sub unit of one ref_currency_unit.
- version (O, I: ref_version(ref_aliasable_data)) (C042, C126)
- This describes the version of this instance as defined by the provider. Each ref_currency_unit may version one ref_version. Inherited from ref_aliasable_data.
Local rules:
- Uniqueness Constraint
- acronym
- Instance Value Constraint
-
sub_unit_per_unit must be null if smaller_unit is null.
