Review and possibly update JSON and YAML file generation to match the SPDX 2.2 spec proposals

[goneall]

Several changes to the JSON and YAML formats were discussed and generally agreed on for the SPDX 2.2 spec.

There is a PR with changes to the example file: https://github.com/spdx/spdx-spec/pull/149. The PR documents the related issues which were resolved (sorry for the extra clicks to find get all the documentation).

The Python libraries may need to be updated to match the 2.2 spec.

[Yash-Varshney]

Hi @goneall . I am interested in updating spdx-python-tools to support spdx v2.2 Can you describe a little bit more about the problem and things needed to be updated further? Thanks for your time.

[goneall]

One suggested approach is to convert the tag/value example file to a JSON using the Python libraries and compare that to the JSON example file. Analyzing the difference should provide a guide as to what needs to be updated.

I used the 2.2 tag example from spdx-spec and converted it to json using the python tools. The converted file is attached.

Using the json-based comparison tooling from spdx-testbed, the following differences were detected:

Using the comparison tooling from spdx-java-library, I didn't find a way so far to list all the detected differences in a nice way. So I will list them manually:

• For LicenseRef-1, names were not equal
• For LicenseRef-2, names were not equal
• For LicenseRef-4, names were not equal
• For LicenseRef-Beerware-4.2, source urls were not equal (second one had none at all)
• For LicenseRef-3, source urls were not equal (second one had none at all)
• Creator information is not equal, but I couldn't find a way to show the differences. Unique creators were Organization: ExampleCodeInspect () and Person: Jane Doe (), I suspect it's the same empty bracket issue found by the json comparison
• For package glibc, a difference was detected. It's not related to filesAnalyzed (as for the json comparison). It showed externalRefsEqual=false, but externalRefDifferences was empty. I couldn't figure out what the detected difference was

Since this post is already quite long, I will do an analysis of the detected differences in a separate post.

Analysis of the differences detected by the json comparison:

One comment beforehand: At the moment, the comparison works by trying to find an exact match and alternatively trying to match by Spdx id if present. If none of the two methods work, it's not matched with anything (leading to two differences, where the respective "other" value is null)

• Organization: ExampleCodeInspect vs Organization: ExampleCodeInspect (): The Python tools remove the empty brackets on writing a document. Honestly, that seems right to me. An issue regarding the example from spdx-spec was created: https://github.com/spdx/spdx-spec/issues/824. The difference regarding Person: Jane Doe is similar
• LicenseRef-1, LicenseRef-2 and LicenseRef-4: They don't have a name in the original document, and the Python tools set the name to the id. See https://github.com/spdx/tools-python/issues/368
• LicenseRef-Beerware-4.2: Was caused by this bug which is already fixed
• LicenseRef-3: Is caused by this bug in the example. Imho, the Python tools actually behave correctly or at least okay here
• The annotation difference is the empty bracket issue again (see above)
• The filesAnalyzed difference was discussed here: https://github.com/spdx/Spdx-Java-Library/issues/142. Seems to be an issue of TagValueStore that filesAnalyzed is automatically modified and set to true

[goneall]

@nicoweidner Based on your analysis, it looks like all Python library related issues have been resolved. It looks like all of the differences listed above are not related to variations from the spec.

If you agree, I think we can close this issue.

[nicoweidner]

Sorry, got interrupted :sweat_smile: . The only thing that may remain questionable in the above list is the fact that the Python tools set the license name to the id if no name is provided and it's not a known license from the list. I am not sure where that part of the logic comes from, and I can't find anything in the spec relating to it. I will create an issue and link it above.

I will also post a quick analysis of the differences detected by the java library, but I think they are pretty much the same (apart from that one case where I don't understand what the difference is supposed to be). Then I will close this.

[nicoweidner]

Analysis of the differences detected by the java library:

• License differences were exactly the same as in the json comparison
• Creator differences are supposedly the same
• No idea what the detected difference for package glibc is

In conclusion, I would say all remaining differences are quite minor, and several of them are not even caused by the Python tools behaving incorrectly. As there are already issues to track everything, I'll close this one.
