VersionInfo

Overview

The VersionInfo class in the TCDX object model provides metadata about the TCDX format version, the TCDX library version, and the tools used to generate the TCDX file. This class is essential for tracking the provenance and compatibility of TCDX files.

Purpose

The primary functions of the VersionInfo class include:

• Tracking version information of the TCDX model and related libraries.
• Providing metadata about the software and tools used to extract TCDX data.
• Ensuring compatibility when analyzing or processing TCDX files across different environments.

By storing this versioning metadata, the VersionInfo class helps maintain data integrity, auditability, and troubleshooting capabilities.

Public Properties

The VersionInfo class consists of the following key properties:
