POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
Defines the types of geometrical relationships. Each of these require some relative knowledge of the geometries of two objects as well as some method of comparing them.
- identifier (M, K, I: ndt_identifier) (C022)
- The name or identifier of the code. Inherited from ref_code.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- 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 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.
- code_alias (I, V: SET[0:?] code_alias(aliased_object)) (C029)
- Indicates the various identifiers by which this data is known. Each ref_geometrical_relationship 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_geometrical_relationship 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_geometrical_relationship may be included in one or more document_information_content. Inherited from e_and_p_data.
- geometrical_relationship (V: SET[0:?] geometrical_relationship(relationship_type)) (C007)
- The Geometrical Relationships which are of this type. Each ref_geometrical_relationship may define the type of one or more geometrical_relationship.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each ref_geometrical_relationship may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- 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_geometrical_relationship may have name specified by one naming_system. Inherited from ref_aliasable_data.
- version (O, I: ref_version(ref_aliasable_data)) (C042, C126)
- This describes the version of this instance as defined by the provider. Each ref_geometrical_relationship may version one ref_version. Inherited from ref_aliasable_data.
