POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
The method used for the coordinate transformation, such as Lambert Conic Conformal, Transverse Mercator, Bursa-Wolf, NADCON, etc. This defines a particular transformation method for which parameters and their usage are specifically described.
- identifier (M, K, I: ndt_identifier) (C025)
- The name of the instance. Inherited from technical_reference.
- reverse_transform_valid (M: ndt_boolean)
- TRUE indicates that the reverse transform is valid using the same parameters. FALSE indicates that the reverse transform is not valid.
- 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.
- sign_reversal (O: ndt_boolean)
- TRUE indicates that the sign of the transformation parameter values must be reversed in order to perform a reverse transformation. FALSE indicates that the sign of the transformation parameter values must not be reversed in order to perform a reverse transformation.
- 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 transformation_method 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 transformation_method 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 transformation_method 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 transformation_method 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 transformation_method may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- map_projection (V: SET[0:?] map_projection(transformation_method))
- These are the map projections that use this method. Each transformation_method may be used by one or more map_projection.
- naming_system (O, I: naming_system(aliasable_technical_reference)) (C028)
- The naming system in which the identifier is specified and determined to be unique. Each transformation_method may have name specified by one naming_system. Inherited from aliasable_technical_reference.
- parameter_usage (V: SET[0:?] transformation_parameter_usage(transformation_method)) (C148)
- This indicates the set of parameters that are defined for use by this transformation method. Each transformation_method may utilize one or more transformation_parameter_usage.
- single_transformation (V: SET[0:?] single_transformation(transformation_method))
- These are the single transformations that use this method. Each transformation_method may be used by one or more single_transformation.
- technical_reference_alias (I, V: SET[0:?] technical_reference_alias(aliased_object)) (C029)
- Indicates the various identifiers by which this instance is known. Each transformation_method may be known by one or more technical_reference_alias. Inherited from aliasable_technical_reference.
- version (O, I: ref_version(technical_reference)) (C042, C126)
- This describes the version of this instance as defined by the provider. Each transformation_method may version one ref_version. Inherited from technical_reference.
Local rules:
- Uniqueness Constraint
- identifier
- Instance Value Constraint
-
SIGN REVERSAL must be specified if REVERSE TRANSFORMATION VALID is true and cannot be specified if REVERSE TRANSFORMATION VALID is false.
