POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
This entity is used to describe the type of binding between shells and regions. A region can be externally bound by only one shell, but may be internally bound by many shells.
- region (M, K: region(shell_region_binding))
- Specifies a region which is being delimited by a shell. Each shell_region_binding must be the binding for one region.
- shell (M, K: shell(shell_region_binding))
- Specifies the shell which is in the role of delimiting a region. Each shell_region_binding must describe the binding use of one shell.
- binding_type (M: ndt_spatial_binding_type) (C006)
- This gives the kind of binding. Allowable kinds of binding are; external, internal.
- 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 shell_region_binding 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 shell_region_binding 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 shell_region_binding may be depicted by one or more graphical_element. Inherited from e_and_p_data.
