POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
The assignment of a geologic age to a geologic object, such as a geologic feature, rock sample, rock body, or rock surface.
- instance_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- instance_create_date (O: TIMESTAMP)
- e_and_p_data.instance_create_date
This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance.
- last_updated (O: TIMESTAMP)
- e_and_p_data.last_updated
This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships).
- r_age_classification_type (FNK, M: CHAR VARYING(80))
- geologic_age_classification.ref_age_classification_type
The type of age classification, such as age of origin, age of last activity, etc.
Defines a foreign key to table r_age_classification_type.
- temporal_object_s (FSK, M: CHAR VARYING(19))
temporal_object_t (M: CHAR VARYING(30))
- geologic_age_classification.temporal_object
Indicates the time event or period which reflects the age of origin of the specified material or geologic feature.
temporal_object_s: Implements a foreign key to a row in one of the tables projected from entity temporal_object depending on the value of the next column (See below).
temporal_object_t: Defines the name of the referenced table. Possible values are: temporal_event, temporal_period (@temporal_object).
- description (O: CHAR VARYING(2000))
- e_and_p_data.description
A remark or comment about the instance.
- instance_creator (O: CHAR VARYING(80))
- e_and_p_data.instance_creator
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance.
- last_updated_by (O: CHAR VARYING(80))
- e_and_p_data.last_updated_by
This records the person or application making the update to this instance.
- source (O: CHAR VARYING(80))
- e_and_p_data.source
The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC".
- source_content (O: CHAR VARYING(80))
- association_reference.source_content
This is the original source of the data. This is the person, company or application that defined or specified the data (content) for this instance and is considered to be responsible for it. For example, POSC, EPSG, API, ISO, etc. This may be the same as or different from the provider of the instance (e.g., POSC).
- source_reference (O: CHAR VARYING(2000))
- association_reference.source_reference
The reference used by source to provide the standard instance, such as Petroleum Industry Data Dictionary (PIDD), Websters Ninth New Collegiate Dictionary, etc.
- status (O: CHAR VARYING(11))
- association_reference.status
The status of this instance in the version of Epicentre running in a data store. This is an enumerated datatype for which the following are the possible values: current, provisional, deprecated. Current - use without restriction. Provisional - use with caution, this value is for comment and may not appear in future releases of Epicentre. Deprecated - avoid use if possible, it is planned to remove this value in the next major release of Epicentre.
- geologic_feature_s (FSK, O: CHAR VARYING(19))
- geologic_age_classification.geologic_feature
Specifies the geologic feature which is being assigned a geologic age.
Defines a foreign key to table geologic_feature.
- material_class_s (FSK, O: CHAR VARYING(19))
- geologic_age_classification.material_class
This is the material class which is being assigned a geologic age.
Defines a foreign key to table material_class.
- reservoir_fluid_system_s (FSK, O: CHAR VARYING(19))
- geologic_age_classification.reservoir_fluid_system
Specifies the fluid system which is being assigned a geologic age classification.
Defines a foreign key to table bulk_material.
- rock_material_s (FSK, O: CHAR VARYING(19))
- geologic_age_classification.rock_material
Specifies the material which is being assigned a geologic age classification.
Defines a foreign key to table bulk_material.
- uncertainty_class_s (FSK, O: CHAR VARYING(19))
- geologic_age_classification.uncertainty_class
Specifies the uncertainty which is being assigned to a geologic age.
Defines a foreign key to table uncertainty_class.
- version_s (FSK, O: CHAR VARYING(19))
- association_reference.version
This describes the version of this instance as defined by the provider.
Defines a foreign key to table r_version.
