POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A spatial model of the earth surface and subsurface, containing a network of earth model objects, such as rock and fluid bodies.
- identifier (M, K: ndt_identifier) (C049)
- The label by which an earth model is identified.
- 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.
- status (O: ndt_instance_status) (C126)
- This is the status of this earth model. PROVISIONAL indicates that the earth model is under construction or is being evaluated but is not yet valid, CURRENT indicates that the earth model is valid, and DEPRICATED indicates that the earth model is no longer valid.
- 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 earth_model 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 earth_model 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 earth_model 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 earth_model 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 earth_model may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- kind (O: ref_earth_model(earth_model)) (C101)
- This is the type of this earth model. This describes the primary purpose for which the earth model was created or is intended to be used. Each earth_model may be define as one ref_earth_model.
- spatial_object (V: SET[0:?] earth_model_composition(earth_model)) (C053)
- Indicates the population of spatial representations which comprise this earth model. Each earth_model may contain one or more earth_model_composition.
