These are the contractual obligations that this business object is designated as fulfilling, either completely or partially. Each core may satisfy one or more contractual_obligation. Inherited from business_object.


secondary_geologic_object_association (I, V: SET[0:?] geologic_object_association(secondary_geologic_object)) (1096, 1226)

Indicates a geologic object association in which a geologic object takes the role of secondary agent. The secondary object relates the primary object to a description. The description does not apply to the secondary object but tells where it is derived from. For example in, "a horizon (primary object) is the top (description) of a sand layer (secondary object)" the secondary object shows where the description is coming from. If the relationship between the two objects is symmetrical both can be described equally well a description, and either could be chosen as the primary agent with the other chosen as the secondary agent. An example of a symmetrical relationship is "a sand layer (primary object) is interbedded (description) with a shale layer(secondary object)". Each core may be involved in one or more geologic_object_association. Inherited from geologic_object.
