We've been working on the basis of what we agreed at the last workshop. 1. We were aiming for a workshop in June. 2. The first phase, consisting of exporting data from the first challenge, - did not require much work (because we did the work at the first challenge) - is a prerequisite to do any thinking in terms of one-to-one integration I agree with Ewa that it would be nice to read the papers of the first challenge. They will become available at the same time as we propose the provenance traces to be made available. It is all complementary.
