----------------------------------------
{quote}As an alternative, you can reuse the name element to write your SPDX ID.
Isn't that enough for the moment?

I tried that, however there are lots of "license variations".
For instance: [http://jtidy.sourceforge.net/license.html]
It is not a "standard" license.
So it is somewhat expected to list that license in pom.xml as
{code:xml}
<license>
<name>Java HTML Tidy License</name>
<url>http://jtidy.sourceforge.net/license.html</url>
</license>
{code}
For most of the cases (all?) it would be equivalent to BSD-3-Clause, however it
would probably be incorrect to label the license as just BSD-3-Clause.
That is why I'm inclined that name/url seem to be not that bad, and it would
probably make sense to have a field for "machine-readable effective meaning" of
the license.

> Key: MNG-6677
> URL: https://issues.apache.org/jira/browse/MNG-6677
> Project: Maven
> Issue Type: Improvement
> Components: POM
> Affects Versions: 3.6.1
> Reporter: Vladimir Sitnikov
> Priority: Major
>
> Current model for license is something, yet it is not machine-friendly.
> Developers tend to put random data into
> {{<license><name>...</name><url>...</url>}}, and it is hard to analyze in
> automatic way.
> What if we could use SPDX license identifiers/expressions for license
> information?
> Note: currently POM allows to list multiple <license> tags, and it is not
> clear how they should be treated (and? or?). So a machine-readable field
> should probably allow for AND/OR license expressions.
> So it would be nice if there was a way to declare a machine-readable license
> tag.
> I'm not affiliated with SPDX, however OSGi use those ids:
> https://osgi.org/specification/osgi.core/7.0.0/framework.module.html#framework.module-bundle-license
