POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A specification for line style which includes characteristics for line patterning, and embedded text and symbols.
- symbol_library (M, K: symbol_library(line_style))
- Indicates the catalog of symbols and patterns in which this line style is specified. Each line_style must be a part of one symbol_library.
- line_style_type (M, K: ref_line_style_type(line_style))
- Indicates the name by which this line style is identified. Each line_style must be identified by one ref_line_style_type.
- line_width (M: ndt_length)
- A specification of line width.
- line_pattern (M: line_pattern(line_style))
- Specifies the internal patterning of a line style, such as dash length and spacing. Each line_style must use one line_pattern.
- 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.
- 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 line_style 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 line_style 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 line_style may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- hatch_line_pattern (V: SET[0:?] hatch_line_pattern(line_style))
- Specifies usage of the style by the hatch lines of a pattern. Each line_style may be used by one or more hatch_line_pattern.
- incell (V: SET[0:?] line_style_cell_composition(line_style)) (C053)
- Specifies the incorporation of a cell within the pattern of a line. Each line_style may contain one or more line_style_cell_composition.
- intext (V: SET[0:?] line_style_text_composition(line_style)) (C053)
- Specifies the usage and placement of text fragments within a line style. Each line_style may contain one or more line_style_text_composition.
- ref_color (O: ref_color(line_style)) (C138)
- Specification of line color. Each line_style may be a color of one ref_color.
- terminal_cell (V: SET[0:?] line_style_terminus(line_style)) (C053)
- Specifies the usage of a cell as the terminus for a line style. Each line_style may contain one or more line_style_terminus.
