I would also be willing to be a Mentor for graphviz.

We've used Graphviz in Taverna since 2005 or so (and still do), and it's
a great product in many ways that I am very grateful for. 

I see from their GitLab what seems like quite stable maintenance
activity across many contributors.

https://gitlab.com/graphviz/graphviz/

(Note: the code license is actually EPL1, not CDL)


The biggest challenge will indeed be the license/IP clearance - do they
have contact with AT&T that can help get a software grant? Then probably
they would need approval from all contributors since to do relicensing
to Apache License 2.0. This could be quite a task.


Some of the optional dependencies under
https://graphviz.gitlab.io/_pages/Download/Download_source.html are as
far as I understand LGPL or GPL - but this seems odd given that EPL
(except EPL2 with secondary license) is incompatible with GPL. Only a
problem for those distributing such binaries though.
