Rudder

We are in the process of evaluating how to do exactly that.
The mains guiding ideas are:

- add the possibility to use JS as a scripting lang in direcitve parameters so that you can manipulate datas,
- add node contextualized data set available in directive parameters (and technique created with the editor)
- allow the user to enrich available data.
- make these data available also on the node as JSON,

Implementation must take care of privacy (i.e, some data must remains on Rudder server and never go to the node), performance (it is absolutly impossible to have a major system wide performance hit (particulary for generation time and agent execution time) if the feature is not used), consistancies (on langage to access data, on way to provide/remove data set, etc), and life cycle (i.e, we must unconsistencies because some data where updated in a dataset, but not in all the place accessing to it).

So, we are still evaluating the pros/cons and looking for alternatives. As soon as it looks less like a big mazzy fog, we will post on rudder-dev to have user feedback.

Hope it helps,

The status of this one is much improved with #9057 (allow ${node.properties[...]} expansion in directive parameters) and #8629 (allow javascript in directive parameters).

Is it sufficient to close that ticket ?
