@stripathy, I guess this would be resolved when the integration of the experiment view, get completed. I mean when everything related to an experiment got integrated into one page (as same as what we have for the create experiment page, now), then all the related objects will be created under the same name.

Also the data history issue (#134) will cover further updates to each experiment (and related objects).
