[NeXus-committee] Proposal for a NeXus TOF raw definition

[Akeroyd, FA (Freddie)]

Ray,

The three facilities are interested in having a unified base for all
instruments to allow for low level instrument debugging tools to be
used, without change, in a given facility. Also, the group was small to
allow for a focused discussion aimed at meeting fast approaching
deadlines. It was also easier to bounce around ideas with a smaller
group. I don't see any problem with the principle of one group
independently doing some initial ground work and then inviting the
committee to comment, and make changes, at a later stage. We are all
busy people and it saves the NIAC members reading/commenting on
something that is not complete. In fact, aren't instrument editors going
to work that way (I believe their remit was to invite opinion from their
respective communities by whatever means is easiest and then put a
proposal to the NIAC).

We did not, of course, plan for the definition to remain permanently on
the second Wiki. During our discussions though we found the "email
notification on page update" feature very useful, but I do not think the
current NeXus Wiki software supports this. If everybody agrees that the
official NeXus Wiki is the best place for discussion of this format then
I will move it there. If having two sets of accounts rather than two
Wikis is your main concern, I would have thought there was a mechanism
to synchronise/share accounts between two Wikis.

Regards,

Freddie
