General¶
Scope¶
This document defines processes to verify the correctness of a Management Information Base (MIB) module contained in NTCIP data dictionary standards and to prepare a stand-alone version of the MIB module. These processes are used by the NTCIP Joint Committee, its Working Groups (WGs), and NTCIP Data Stewards.
Note
MIB modules created prior to NTCIP 8005 v2.0.0 were developed using the Structure and Identification of Management Information (SMI) version 1, as defined in IAB STD 16, and were based on a different syntax checker than what is identified in NTCIP 8005 v2.0.0.

Terms¶
For the purposes of this document, the following terms and definitions apply. Terms not defined here are used in accordance with their definitions in ISO/IEC/IEEE 24765. Words not defined here or in ISO/IEC/IEEE 24765 are used in accordance with their definitions in Webster’s New Collegiate Dictionary.
| Term | Definition |
|---|---|
| Data Steward | An organizational element of the ITS community responsible for ensuring that the information in the MIB module portion of any NTCIP data dictionary standard is accurate and does not duplicate information in other standards. |
| management information base (MIB) | A structured collection of managed information contained within a SNMP context. A MIB represents the instantiated data objects defined by one or more MIB modules and integrated into a device or management station. |
| MIB module | A sequence of NVT ASCII characters conforming to X.208 Abstract Syntax Notation One (ASN.1) and IAB STD 58. MIB modules are used to define the data objects that are to make up the instantiated objects of the MIB. NOTE—A MIB module can be, and within NTCIP typically is, presented as both part of a standard and as a stand-alone, computer-readable text file. When a MIB module is presented within a standard, there are usually document section headings included that are not technically part of the MIB Module. |
| MIB file | Stand-alone computer readable file that represents one or more MIB modules. |
