POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
Defines a logical flag for each node of a grid. The semantics of the flag must be defined by the relationship to the "object" and by the grid used by the element.
- source_event_definition (O, K: seismic_geometry_set(source_event_invalid))
- May be a property of seismic geometry set. Data value defines a "source event invalid" flag for each source event. The grid used by data value must be the same as was used by attribute source event uid in the associated seismic geometry set. Each pty_logical_array may be a source invalid property of one seismic_geometry_set.
- inflection_station_definition (O, K: seismic_geometry_set(station_inflection))
- May be a property of seismic geometry set. Data value defines an "inflection point" flag for each station. The grid used by data value must be the same as was used by attribute seismic station uid in the associated seismic geometry set. Each pty_logical_array may be a station inflection property of one seismic_geometry_set.
- surveyed_station_definition (O, K: seismic_geometry_set(station_not_surveyed))
- May be a property of seismic geometry set. Data value defines a "station not surveyed" flag for each station. The grid used by data value must be the same as was used by attribute seismic station uid in the associated seismic geometry set. Each pty_logical_array may be a station not surveyed property of one seismic_geometry_set.
- offline_station_definition (O, K: seismic_geometry_set(station_offline))
- May be a property of seismic geometry set. Data value defines an "offline location" flag for each station. The grid used by data value must be the same as was used by attribute seismic station uid in the associated seismic geometry set. Each pty_logical_array may be a station offline property of one seismic_geometry_set.
- potential_field_meas_infl (O, K: potential_field_geometry_set(measurement_inflection)) (C112)
- Data value defines an "inflection point" flag for each measurement. The grid used by data value must be the same as was used by attribute measurement uid in the associated potential field geometry set. Each pty_logical_array may be a measurement inflection property of one potential_field_geometry_set.
- potential_field_stn_inflection (O, K: potential_field_geometry_set(station_inflection)) (C112)
- Data value defines an "inflection point" flag for each station. The grid used by data value must be the same as was used by attribute station uid in the associated potential field geometry set. Each pty_logical_array may be a station inflection property of one potential_field_geometry_set.
- activity (O, K, I: activity(process_data))
- Defines the activity which created this instance. Each pty_logical_array may be the result of one activity. Inherited from process_data.
- data_value (M: ndt_logical_array)
- Defines a logical flag at each node.
- 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.
- preferred_flag (O, I: ndt_boolean)
- The flag is set to True if this instance of property is the preferred value in this data store of this type of property for the object which this property describes. Inherited from property.
- 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 pty_logical_array 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 pty_logical_array 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 pty_logical_array may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- process_data_item (I, V: SET[0:?] process_data_item(process_data))
- Defines where this data was used by an activity. Each pty_logical_array may be the value for one or more process_data_item. Inherited from process_data.
- represent (O, I: property(representations)) (C125)
- This is the property that is the original for which this representation is an equivalent representation. Each pty_logical_array may be an equivalent representation of one property. Inherited from property.
- representations (I, V: SET[0:?] property(represent)) (C125)
- This designates other properties that are stated to be equivalent representations of this property representation, such as the same geometry using another coordinate system. Each pty_logical_array may have as equivalent representations one or more property. Inherited from property.
Local rules:
- Uniqueness Constraint (C010)
- source_event_definition, inflection_station_definition, surveyed_station_definition, offline_station_definition, potential_field_meas_infl, potential_field_stn_inflection, activity
- [I: property] Mandatory Relationship Set
-
Each PROPERTY must "be a property of" one object.
