POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
Alternate names assigned to an object, usually defined by a company for local use or by an external organization for worldwide use. The name may or may not be globally unique but is unique for an object in a data store within the context of the naming system. At a site, if aliases are specified for objects then the all object identifiers should also be included as aliases. If an object has an alias then the naming system should be specified for the object. The alias identifier may be substituted for the identifier in the object as long as uniqueness and string length constraints are observed.
- identifier (M, I: ndt_identifier) (C025)
- The name of the instance. Inherited from technical_reference.
- naming_system (M: naming_system(object_alias)) (C028)
- Specifies the name space within which this object identifier is defined and is unique. Each object_alias must have name specified by one naming_system.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- effective_date (O: ndt_date)
- The date that the alias was put into effect.
- expiry_date (O: ndt_date)
- The date at which the alias is no longer effective.
- instance_create_date (O, I: ndt_date_tod) (C126)
- This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- last_updated (O, I: ndt_date_tod) (C126)
- This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
- 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 technical_reference.
- 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 technical_reference.
- 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 technical_reference.
- 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 object_alias may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- derived_interest (I, V: SET[0:?] derived_interest_makeup(interest_for)) (C071, C122)
- These are the ownership fractions for business associates of this object. Each object_alias may be referenced by one or more derived_interest_makeup. Inherited from object_of_interest.
- 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 object_alias 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 object_alias may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- involving_activity (I, V: SET[0:?] object_activity_involvement(involved_object)) (C056)
- This are the activity involvements which affect the object. Each object_alias may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- version (O, I: ref_version(technical_reference)) (C042, C126)
- This describes the version of this instance as defined by the provider. Each object_alias may version one ref_version. Inherited from technical_reference.
