Yes Matthias, I agree that high-level application developers should be included in our discussion at some point. I've started speaking with Greg White here at SLAC, as well as some other accelerator physicists with varying degrees of EPICS familiarity.

I'm very interested in the V4 API, and will certainly be spending more time on it before the July meeting. I've got ideas on what the API should include (perhaps too many!), but without a lot of V3 programming experience myself, I might be spending more time on gathering ideas from folks that *do* have experience.

However, I would like to get something written down and communicated in our group before talking with accelerator physicists and other app developers. Backwards as it seems, in my experience of asking the API users what they would like to see in an interface, I've often received a list of variations on familiar features before any new and innovative ideas, and it's easier if we have a starting point to proceed (or back away) from.

I would like to organize my ideas and existing notes, share them with Kay and Bob, then post some notes on the Wiki. And of course, I need to look closely at Jeff's lower level spec. There's only a month before our meeting, so I'll try and get this together right away.

Dear all,

. . .

Another issue:
It comes to my mind that the interface for channel access V4 should be also discussed and defined by those people writing the high level (machine)physics applications. They will probably have the highest demand for new features. I am thinking of guys like Tom Pelaia, Roland Mueller, Greg White, (Andy Goetz?), and someone from Argonne, Jlab, Cosylab...
Should we pass them the current state and ask them for their comments?
Even though this functionality will be mainly used in EPICS Office applications I think we should discuss it inside and outside the EPICS Office framework. Please let me know what you think about it.
Will Kay and Doug coordinate this issue? Otherwise I'll be glad to help.

Looking forward to see you next month.

Regards
Matthias
