| Existence_Kind | REF_EXISTENCE_KIND | NA |
A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual. | Yes Actual |
VARCHAR2(64) |
| GUID | STRING128 | NA |
Globally Unique IDentifier for an instance of a class. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. | No |

|---|---|---|---|---|
| Activity_Facility_Invl | Position | The position at which the facility is located. This should be normally used for facilities installed on the surface (though it can be used for tracking the position of a downhole facility in case of a deviated well). The position of a facility can change over time | Control | No |
| Alternate_Position | Position | The identifier of the original position, for which this is an alternate position. | Cascade | No |
| Area_Vertex | Position | A type of vertex that is located in, on, or above the Earth but is always locatable using a geo-referenced coordinate system. | Control | No |
| Basin | Nominal_Position | The nominal position of the item. Considering the item has a spatial extent - meaning it is not a single point and could span more than one county or section or whatever - the Position created as the target of this link is just a representative location. If a more complete answer is needed a GIS query can intersect the polygon marking the outer boundary of this item with the desired item. For example, the Viking Graben (a basin) is mostly in Norway but extends over the border into the UK. Its Nominal_Position could be said to be Norway. If someone wondered exactly which countries it touched they would use GIS functionality to intersect the basin outline with a map layer containing the international boundaries to see which countries actually contain some portion of the basin | Control | No |
