[bact]

• Add spdx3-validate to bin/check-examples.sh script
• spdx3-validate can handle spdxId references with ExternalMap
• It is currently used in https://github.com/spdx/spdx-examples/blob/master/.github/workflows/pull_request.yml
• This PR also modified bin/check-examples.sh to print relevant environment variables to assist debugging
• It is also update the value of software_packageVersion in examples/jsonld/package_sbom.json to match the version appears in the software_downloadLocation

Validation failed due to individual-related issue. Turn to draft for now.

The validation script can run and print results as expected.
(But the validation result of the file being tested is failed)

LGTM - Thanks @bact

[goneall]

It looks like the validation is failing - it also failed on a previous PR - so likely not do to these changes.

@bact - if you find the source of the failure, can you include a fix in this PR?

[bact]

@goneall the validation fail is from the known issue of missing CreationInfo for individuals.

We need to add it when generating the ontology file, with this PR spdx/spec-parser#154 or similar.

[bact]

@goneall @zvr @ilans the CreationInfo issue is probably fixed now. But because of the assessedElement range update, the example failed. I will update the example and check again.

[bact]

@goneall @zvr @ilans The old 5 violations about missing CreationInfo are fixed.
But we have new violations about new 5 cretionInfo_*.

I opened a separated issue for that at spdx/spdx-3-model#936

[bact]

Example validation is passed now.
