          • fixed the ESAP-GUI usability issues and bugs with the shopping basket that were identified
          • improved (and understood) the token expiration issue (not fully solved, because it was not on the board for this iteration)

      5. Upcoming Workshop 15m

      The Second WP5 Workshop will take place on Thursday 5 August from 09:00 until 12:00 CEST.

      Details are starting to appear on Indico at https://indico.in2p3.fr/event/24716/

      As a reminder, this workshop is required to satisfy the project milestone MS31, “Second WP5 workshop to analyse prototype performance”.

      I interpret this as being a charge to invite various ESCAPE stakeholders to the workshop, to present the work which as been done to date, to give them a chance to experiment with it, and to ask them for their feedback. (I regard “performance” as describing the holistic design and concept of the ESAP — “how well does it do its job?” — rather than some limited definition which regards purely computation/query performance.)

      The draft agenda at the Indico page linked above includes:

      - An overview of the ESAP “vision”, together with some discussion of how it relates to the expressed use cases.

      - Discussion of current and upcoming work in interactive data analysis, batch processing, and managed databases.

      - Interactions with other work packages.

      - Time for discussion.

      Your feedback on what else should be added to the agenda, and — in particular — on what you could contribute would be much appreciated.
