POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
This is a component of a document schema that represents a distinct, structurally meaningful part of a document specification, such as a title, an acknowledgement, a chapter, a footnote, etc. Text blocks are not usually described as document schema elements unless they are part of the structure of document, such as an introduction, body or conclusion, etc.
- document_schema (M, K, I: document_schema(document_schema_part)) (C136)
- This is the document schema that this component is a part of Each document_schema_element must be a part of one document_schema. Inherited from document_schema_part.
- identifier (M, K, I: ndt_identifier) (C025)
- The name of the instance. Inherited from technical_reference.
- cardinality (O: ndt_pint1) (C136)
- This specifies the maximum number of elements of this type that may be included in a document specification using this document type definition. If NULL, the number of elements is unrestricted.
- component_sequence (O, I: ndt_pint1) (C136)
- This is the sequence number of this part within the document schema. This defines the order of this part within the document. A NULL or a value of zero ('0') states that the part has no order. Multiple parts with the same sequence value means that these parts may appear in any order relative to each other but they appear at the same place within the document. Inherited from document_schema_part.
- compositor (O: ndt_compositor) (C136)
- This specifies the behavior of the part elements for this element. This defines if a sequence of the part elements is permitted or required, if a choice is permitted or required, if choices are repeated, and if elements are required.
- 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.
- kind (O: ndt_text_132) (C136)
- This specifies the type of the element as defined in the XML Schema, describing either the simple or complex type to which this element is constrained.
- 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.
- optionality (O: ndt_boolean) (C136)
- This defines the optionality of this element within the document type definition. If FALSE, this element must be included in a document specification conforming to this document schema. If TRUE or NULL, this element may be omitted.
- 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 document_schema_element 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 document_schema_element 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 document_schema_element may be included in one or more document_information_content. Inherited from e_and_p_data.
- document_schema_attribute (V: SET[0:?] document_schema_attribute(document_schema_element)) (C136)
- These are the attributes of this element in a document type definition. Each document_schema_element may have one or more document_schema_attribute.
- document_specification_part (I, V: SET[0:?] document_specification_part(document_schema_part)) (C136)
- These are the parts of documents which are of the type defined by this document schema part. Each document_schema_element may be used to define one or more document_specification_part. Inherited from document_schema_part.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each document_schema_element 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 document_schema_element may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- 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 document_schema_element may have name specified by one naming_system. Inherited from aliasable_technical_reference.
