Hi guys, I’ve been keeping an eye on this because I also want to reproduce the wikipedia prov. I am at lost which one I should go for now. Spoiled with choices :) btw, I am cc’ing prov-commnets to see whether it is now working.

Firstly, the revision length determines the max. number of wasRevisionOf re- lations traversed, towards the past, from a landing revision page. Secondly, the max users parameter determines the max number of wasAssociatedWith relations, i.e., the max number of contributions explored per user. Thirdly, the depth parameter determines how many times the switch- over between article space and user space may occur. For example, setting depth = 3 results in the exploration of re- visions for articles that are connected to the original seed article through at most 2 intermediate users: base article → user1 → article2 → user2 → article3. >> >> >>> >>>> >>>> sorr yI am rushing to ask before I look :-) >>> >>> No worries.
