ReqIF Version Support in DX

Overview

This article explains which ReqIF versions are supported by Data Exchange (DX) and clarifies why ReqIF version 1.0 appears in file headers, even when 1.2 is the latest standard.

1. What Version of ReqIF Does DX Support?

✔ DX supports all versions of ReqIF, including 1.2.
✔ The latest ReqIF specification (1.2) is maintained by OMG:

• OMG ReqIF 1.2 Specification

✔ Why Does the ReqIF Header Say Version 1.0?

• Even in ReqIF 1.2, the file header specifies version 1.0.

• This is expected behavior because the ReqIF specification itself defines 1.0 in the header, regardless of the version.

✔ Example ReqIF Header:

<REQ-IF VERSION="1.0">

• This does not indicate an outdated version—it is part of the ReqIF standard.

2. How Does DX Handle ReqIF Versions?

✔ DX reads and processes ReqIF 1.0–1.2 files without issue.
✔ The version in the header does not impact compatibility.
✔ No special configuration is needed when importing ReqIF 1.2 files into DX.

✔ Key Takeaway:

• If a ReqIF file states version 1.0 in the header, it is still valid for ReqIF 1.2.

• DX fully supports the latest ReqIF standard without requiring updates.

3. Best Practices for Handling ReqIF Versioning in DX

✅ Do not be concerned if the ReqIF header shows version 1.0—this is expected.
✅ Ensure that the ReqIF file structure follows the latest standard if needed.
✅ If experiencing compatibility issues, validate the ReqIF file using ReqIF Studio.

4. Conclusion

• DX supports all ReqIF versions, including 1.2.

• The file header always shows version 1.0, even in ReqIF 1.2, as per the standard.

• DX does not require special handling for different ReqIF versions.
