This is a descriptive text that is versionable for the object it describes, that is, several different opinions about an object can be recorded, together with information about the activities that lead to the forming of these opinions, and the geoscientist/engineer concerned.

material_sample (O, K: material_sample(descriptive_text))

Where the descriptive text is describing a material_sample, this points to the instance of material_sample being described. Each pty_descriptive_text may be a property of one material_sample.


wellbore_interval (O, K: wellbore_interval(descriptive_text))

Where the descriptive text is describing a wellbore_interval, this points to the instance of wellbore_interval being described. Each pty_descriptive_text may be a property of one wellbore_interval.


wellbore_point (O, K: wellbore_point(descriptive_text))

Where the descriptive text is describing a wellbore_point, this points to the instance of wellbore_point being described.


kind (O, K: ref_descriptive_property)

This give the kind of descriptive property this is, by pointing to the reference entity ref_descriptive_property.


activity (O, K, I: activity(process_data))

Defines the activity which created this instance. Each pty_descriptive_text may be the result of one activity. Inherited from process_data.


other_spatial_object (O, K, I: other_spatial_object(property))

Each pty_descriptive_text may be a property of one other_spatial_object. Inherited from property.


data_value (O: ndt_comment)

This contains the text that is the value in the versionable property.


preferred_flag (O, I: ndt_boolean) (1047)

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.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each pty_descriptive_text may be a member of one or more data_collection. Inherited from e_and_p_data.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each pty_descriptive_text may be depicted by one or more graphical_element. Inherited from e_and_p_data.


process_data_item (I, V: SET[0:?] process_data_item(process_data))

Defines where this data was used by an activity. Each pty_descriptive_text may be the value for one or more process_data_item. Inherited from process_data.

Local rules:

Uniqueness Constraint
material_sample, wellbore_interval, wellbore_point, kind, activity, other_spatial_object
[I: property] Mandatory Relationship Set
Each PROPERTY must "be a property of" one object.
Supertype path(s):
process_data > property > pty_descriptive_text.
e_and_p_data > property > pty_descriptive_text.
