POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
The association of a cell type and area pattern for the purpose of describing the relative placement of a cell in an area pattern.
- identifier (M, K: ndt_identifier) (C049)
- The label used to identify an area cell.
- cell (M, K: cell(area_cell))
- Specifies a cell for participation in the definition of an area pattern fill. Each area_cell must reference one cell.
- cell_height (M: ndt_length)
- The length of a cell in the vertical dimension within a pattern fill.
- cell_orientation_angle (M: ndt_plane_angle)
- The angle by which a cell is rotated when displayed in a pattern fill. The angle is measured counter-clockwise from the horizontal.
- cell_width (M: ndt_length)
- The length of a cell in the horizontal dimension.
- horizontal_spacing (M: ndt_length)
- The distance separating cell origins along a row of cells.
- vertical_spacing (M: ndt_length)
- The distance by which a cell origin is displaced from adjacent cell origins in a column of cells.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- horizontal_offset (O: ndt_length)
- The distance in the horizontal direction separating the origin of the display coordinate system and the origin of one cell in the pattern. This distance could reference the nearest cell, but any cell is adequate.
- 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.
- vertical_offset (O: ndt_length)
- The distance by which a pattern of cells is displaced in the vertical direction from the origin of the display coordinate system.
- 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 area_cell 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 area_cell 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 area_cell 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 area_cell 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 area_cell may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- pattern_fill (V: SET[0:?] area_pattern_cell_inclusion(area_cell)) (C053, C141)
- Specifies the area pattern fill in which cells are included as part of the pattern. Each area_cell may be a part of one or more area_pattern_cell_inclusion.
