Allow for Apache-2.0 License in metainfo

[awarnke]

Hello,

Currently, there is an error report for project https://tracker.debian.org/pkg/crystal-facet-uml

stating " metainfo-license-invalid The MetaInfo file does not seem to be licensed under a permissive license. " but Apache-2.0 should be pemissive enough (see http://spdx.org/licenses/ ):

crystal-facet-uml <metadata_license>Apache-2.0</metadata_license> <project_license>Apache-2.0</project_license> see https://github.com/awarnke/crystal_facet_uml/tree/master/installation_linux

Could you allow this type of License-information?

Kind Regards Andreas

Checking issue #195 i guess i start understanding the bug: Only the <metadata_license>MIT</metadata_license> needs to be adapted, not the <project_license>Apache-2.0</project_license> ? The Error message seems to state this - maybe it helps making this more clear in the error message text?

I see that you need the MIT License for this file.

Is it possible to provide the metainfo.xml under two licenses: MIT for appstream purposes and Apache-2.0 to avoid the lintian-checker bugs due to mismatches between metainfo.xml and debian/copyrights ?

This does sound like a Lintian bug!

So, the project_license is what the project, its code and data are actually licensed under, the metadata_license is what the MetaInfo file only is licensed under.. I think this may actually have been addressed in Lintian by now :-)

Thank you for checking. My current setup seems to work:

<metadata_license>CC0-1.0</metadata_license> <project_license>Apache-2.0</project_license>

My current setup seems to work

Yes, this is how it's meant to be :-) Thank you for updating that metadata!
