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.
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.
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.
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.
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.
Indicates the data collections that include this instance of E and P data. Each pty_directional_permeability may be a member of one or more data_collection_content. Inherited from e_and_p_data.
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_directional_permeability may be included in one or more document_information_content. Inherited from e_and_p_data.
Specifies one or more graphical elements which are depicting this data item. Each pty_directional_permeability may be depicted by one or more graphical_element. Inherited from e_and_p_data.
This describes the orientation of the permeability when not described by azimuth and inclination. Each pty_directional_permeability may has orientation defined by one ref_flow_orientation.
Defines where this data was used by an activity. Each pty_directional_permeability may be the value for one or more process_data_item. Inherited from process_data.
The meaning of North, e.g., true or magnetic. This is the direction from which an angular offset was measured. Each pty_directional_permeability may have an orientation relative to one ref_north_axis_direction.
This is the property that is the original for which this representation is an equivalent representation. Each pty_directional_permeability may be an equivalent representation of one property. Inherited from property.
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_directional_permeability may have as equivalent representations one or more property. Inherited from property.
