A set of property types used to constrain the ref properties that can be associated with a point, element, sparse or sample data types. A data type instance may only reference ref properties which are of the type contained in the ref property set specified for the data type.

name (M, K: ndt_name)

A unique name for the property set.


ref_property_set_type (M: ref_property_set_type)

Gives the type of the property set. Each ref_property_set must have one ref_property_set_type.


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 ref_property_set must provided by one ref_source. Inherited from reference_behavior.


description (O: ndt_comment)

A description of the purpose of the property set.


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.


use_limit (O: ndt_pint2)

The number of set members that may be used in a point, element, sparse or sample data type instance. If undefined (null) all members of the set are implied.


code_alias (I, V: SET[0:?] ref_code_alias(standard_code))

Defines a list of alternative names associated with this instance. These may be aliases, translations, codes, etc. Each ref_property_set may have one or more ref_code_alias. Inherited from ref_code.


ref_property_type (O: SET[0:?] ref_property_type)

Gives the property types that are members of the set. Each ref_property_set may contain one or more ref_property_type.


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 ref_property_set 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 ref_property_set may version one ref_epicentre_version. Inherited from reference_behavior.

Local rules:
