|---|---|---|---|---|
| Boundary | Domain_Property | The property of the domain in which the boundary is defined. For example, a boundary defined in time domain property in time might be One_Way_Time or Two_Way_Time. Similarly, a boundary defined in depth might have a domain property of Measured_Depth or True_Vertical_Depth. | Restrict | No |
| Checkshot_Survey | Depth_Property | The depth property used for Velocity_Datum_Depth time-depth pairs, for example, True_Vertical_Depth or Measured_Depth. | Restrict | Yes |
| Checkshot_Survey | Time_Property | The time property used for time-depth pairs, One_Way_Time or Two_Way_Time. | Restrict | Yes |
| Entity_Doc_Involvement | Index_Type | The index type for the involvement. Examples of this would be Length, Depth etc | Restrict | No |
| Flat_Property_Grid | Property_Type | The property describing the values in the property grid. | Restrict | Yes |
| Horizon_2D_Interp_Geom | Domain_Property | The property of the domain in which the geometry is defined.. For example, the domain property of a geometry defined in time might be One_Way_Time or Two_Way_Time. Similarly, a geometry defined in depth might have a domain property of Measured_Depth or True_Vertical_Depth. | Restrict | No |
| Horizon_2D_Interp_Pty | Property_Type | The property that the data represents. | Restrict | No |
| Indexed_Parameter | Index_Type | The index type for the paramter. Examples of this would be Length, Depth, Two Way Time. | Restrict | No |
| Log_Channel_Remark | Index_Type | The index type for the remark. Examples of this would be Length, Depth etc | Restrict | No |
| Log_Channel_Set | Index_Property | The property type attribute describes implicit indexes defined by the Index_Min, Index_Max and Spacing. This value will be NULL for Log_Channel_Sets with well defined explicit Log_Channel indexes, such as MD or TVD, | Restrict | No |
| Log_Image_Part | Index_Type | The index type for the involvement. Examples of this would be Length, Depth etc | Restrict | No |
| Point_Geometry_Set | Domain_Property | The property of the domain in which the geometry is defined. For example, the domain property of a geometry defined in time might be One_Way_Time or Two_Way_Time. Similarly, a geometry defined in depth might have a domain property of Measured_Depth or True_Vertical_Depth. | Restrict | No |
| Point_Property_Set | Property_Type | The property describing the values in the property point set. | Restrict | Yes |
| Polyline_Geometry_Set | Domain_Property | The property of the domain in which the geometry is defined. For example, the domain property of a geometry defined in time might be One_Way_Time or Two_Way_Time. Similarly, a geometry defined in depth might have a domain property of Measured_Depth or True_Vertical_Depth. | Restrict | No |

| R_Log_Channel | Property_Code | The property which a curve type represents. This is the physical quantity measured by the log channel. | Restrict | Yes |
| R_Measurement_Tag_Cat | Property_Code | The property represented by this measurement tag (e.g. Pressure, Temperature) | Restrict | No |
| R_Property | Parent_Property | Reference to the parent property that classifies in a more general way this property. | Cascade | No |
| R_Unit_Assignment | Property | This association is the assignment of the Seabed storage unit of measure to a Property. | Restrict | Yes |
| Ref_Parameter_Entity | Property | A characteristic of an object that can be measured or described. Examples include, Acoustic Velocity and Wellbore Shape. | Restrict | Yes |
| Seismic_Line_Correction | Shift_Property_Type | Refers to the property of the shift attributes. | Restrict | No |
| Time_Series | Property | The property recorded for the time series data. | Restrict | No |
| Uncertainty_System | Restrict_To_Property | The name of a Property controlled by this Uncertainty_System. For example, if this value is "permeability", then it is implied that every permeability value in the database has this uncertainty associated with it. If missing, no Property restriction is assumed to apply. Note: The association with Property also provides information about the units of uncertainty, which if meaningful and not inherent to the uncertainty family, are constrained to match the Property Cannonical_Unit. For example, if the uncertainty value applies to everything with a certain Property type, then the parameter value must be in the same unit as the Property unit - if that parameter value is expressed in a unit of measure. | Restrict | No |
| Velocity_Function | Value_Property | The property of the function value, such as interval velocity or two way time. | Restrict | No |
| Velocity_Set | Index_Property | The property of the index for the time depth pairs. Values are Two_Way_Time, One_Way_Time, Measured_Depth, True_Vertical_Depth | Restrict | Yes |
