Since you need to detect who changed what the only way I can see to do this is turn on authentication on Fuseki and track changes made through it.
You could bastardise the permissions layer[1] to do what you want. The permissions layer will let you filter down to the actions on the triples, rather than implementing a SecurityEvaluator to perform the restriction you could implement it record all changes (including who made them) in any storage and format you wish. 1. https://jena.apache.org/documentation/permissions/index.html On Fri, Oct 27, 2017 at 11:42 AM, anuj kumar <anuj.gandh...@gmail.com> wrote: > Hi Jena Users, > I have a query regarding the most effective way to capture changes in the > underlying Triple Store. > I have a requirement where: > 1.
