[wvdemeer]

Below is a literal copy of google doc issue 21:

1. Time reservations support -- small changes in the AM API and largest part in RSpecs -> github workflow proposal

Jordan: A proposal to support time reservations has been jointly discussed, proposed and implemented by INRIA, UPMC, UTH with respect to the following testbeds: PLE, IoTLAB, NITOS. Most of the proposition is about RSpecs, but it also impacts some options in the AM API. We need to be sure to gather all involved partners in the discussion. This is a feature that is highly used in current projects and not yet “standardized” in the AM.
