Heya Justin, Ya, we discussed this in our slack - but we have some inconsistency across the projects. PageRank is used in the exact same matter as we us in numerous projects, as example Spark, Flink. This causes confusion - I argued the same as you: "We used a piece of code which hasn't a proper license. As long as we use code from compatible projects and licenses everything is fine. We only have to mention this. But Justin said we copied from Wikipedia, which is a license issue”
From Wikipedia [1] "Most of Wikipedia's text and many of its images are co-licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License (CC BY-SA) and the GNU Free Documentation License (GFDL) (unversioned, with no invariant sections, front-cover texts, or back-cover texts)." I reached to twitter - even they use PageRank in their own code [2]. What’s now the best solution to solve this? Also in view of the TLPs Spark, Flink ...
