POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
An association indicating a document specification class being classified to be a member of another document specification class. A class can be classified many ways.
- have_as_a_member (M, K: document_specification_class(be_a_member_of))
- Indicates the class that is being classified as a member of another class. Each document_spec_class_clsn must have as a member one document_specification_class.
- be_classified_as (M, K: document_specification_class(classify))
- Indicates the class that the member is being classified as. Each document_spec_class_clsn must be classified as one document_specification_class.
- 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 association_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 association_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 association_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 document_spec_class_clsn 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 document_spec_class_clsn 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 document_spec_class_clsn may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- version (O, I: ref_version(association_reference)) (C042, C126)
- This describes the version of this instance as defined by the provider. Each document_spec_class_clsn may version one ref_version. Inherited from association_reference.
