Are you comfortable sharing which tooling you are using for this? e.g. is it Backstage, a custom built site, something else?

For the documentation portal we are using MkDocs in combination with our internal docs-theme we maintain (reused > 2400 times, also Inner Source). But we also have a dedicated app using Django and another popular innersource framework for the UI, there we have detailed re-use metrics and do also calculate the re-use, usage, quality metric and much more.

Thanks for the additional info @bufferoverflow. The measurement of re-use could even be a pattern in its own right but lets keep that for another day :) (I made a note of that)

How do you list the InnerSource projects? Do you just use the features of your gitlab instance to do that, or is there a dedicated places that shows InnerSource projects only?

We're listing inner source projects on a dedicated page, also including additional data mentioned by @bufferoverflow above.

@spier Yes, I think that would be worth to do. It's especially useful for reporting and if people see the numbers of re-use they could imagine the savings we had due to re-use Inner Source. This really helps to convince people.

* Used in SAP's InnerSource project portal to define the default order of the InnerSource projects. It was first created in July 2020 and is fine-tuned and updated frequently ever since. When proposed to the InnerSource Commons in July 2020, this pattern emerged. Also see [Michael Graf & Harish B (SAP) at ISC.S11 - The Unexpected Path of Applying InnerSource Patterns](https://www.youtube.com/watch?v=6r9QOw9dcQo&list=PLCH-i0B0otNQZQt_QzGR9Il_kE4C6cQRy&index=6).
* Airbus took a lot of inspiration from this pattern to create an "InnerSource score" that combines the activity score together with checks from the [Standard Base Documentation](./base-documentation.md) and the [InnerSource License](./innersource-license.md).
* Siemens includes repository activity in their InnerSource project quality score. Maintainers can use the quality score to improve their project and communicate their score via badges.
