| 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 |

| Seismic_Line | Source_Dataset | The seismic dataset from which this seismic line was created/generated. This link’s usage varies greatly depending whether the seismic line is for a 3D or 2D survey. FOR A 3D SURVEY, it represents the seismic dataset which was used to generate this seismic line. A single 3D dataset can be used to generate many lines. FOR A 2D SURVEY, this represents the seismic dataset which was used to generate this VIRTUAL seismic line. The Seismic_Line link in Seismic_Dataset_2D identifies the ACTUAL line generated using the dataset. In 2D surveys, many datasets may be used to create a single actual line. This link identifies which dataset was used to generate this VIRTUAL seismic line segment of the actual seismic line. The preferred way to represent the line segments which make up the line is to use the Seismic_Line_Segment entity rather than creating VIRTUAL lines. If this is populated (for 2D surveys), then EXISTENCE_KIND should be “Virtual” otherwise should be “Actual” | Nullify | No |
