Specifies the name space within which this object identifier is defined and is unique. Each earth_surface_feature_alias must defined within one ref_naming_system. Inherited from object_alias.


earth_surface_feature (M, K: earth_surface_feature(earth_surface_feature_alias))

Specifies the feature which is known by this identifier. Each earth_surface_feature_alias must identify one earth_surface_feature.


identifier (M: ndt_long_name) (1144)

A name or idenfifier assigned to an earth_surface_feature.


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 earth_surface_feature_alias must provided by one ref_source. Inherited from reference_behavior.


description (O, I: ndt_comment)

A description or remark about the alias. This may include information about the reason the alias exists, or a comment about the meaning or derivation of the alias. Inherited from object_alias.


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.


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

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

Specifies one or more graphical elements which are depicting this data item. Each earth_surface_feature_alias 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 earth_surface_feature_alias may object of ranking one or more object_ranking. Inherited from object_of_interest.


source_reference (O, I: ref_source_reference)
