This object provides a method to create and delete a Data Inventory IdrField. Supported states are: active(1), notInService(2), createAndWait(5), destroy(6) The RowStatus textual convention is used to manage the creation and deletion of conceptual rows, and is used as the value of the SYNTAX clause for the status column of a conceptual row (as described in Section 7.7.1 of [2].) The status column has four defined values: - `active(1)', which indicates that the conceptual row is available for use by the managed device. For it to in such state, the columnar objects: hpiIdrFieldType, hpiIdrFieldTextType, hpiTextLanguage, and hpiIdrFieldText must have valid values. - `notInService(2)', which indicates that the conceptual row exists in the agent, but is unavailable for use by the managed device (see NOTE below); 'notInService' has no implication regarding the internal consistency of the row, availability of resources, or consistency with the current state of the managed device. - `createAndWait(5)', which is supplied by a management station wishing to create a new instance of a conceptual row. After setting this value, the management station is responsible of providing valid values to the columnar objects: hpiIdrFieldIsReadOnly, hpiIdrFieldType, hpiIdrFieldTextType, hpiTextLanguage and hpiIdrFieldText. - `destroy(6)', which is supplied by a management station wishing to delete all of the instances associated with an existing conceptual row.
