About the PageRank I could not understand the issue with that, because the algorithm is well documented, it is like "bubble sort", and because of it, the algorithm implementation will look similar. Including the issue that our API is similar to Apache Spark and Apache Flink, then more similar will look the implementation, but it is not a copy from any page.
Because If we try to add a license, the algorithm itself does not have a patent from 2011 as far I know, is it common domain or not ? In the case of Apache Spark they have the same [1] as us, and they didn't mention other licenses at any place for the PageRank. Then I could not understand the issue.
