Mathias:
When we last looked at this, here is the decision we reached regarding
UPPER/lower case:
"Also, advise that lower case is preferred unless there is a compelling
case for upper case. AND that the difference between upper and lower
case is significant."
see full context: http://www.aps.anl.gov/bcda/aps/namingConvention.php
Without defining a standard rule, it seems that our accelerator tends to
use UPPER case while our beamlines tend to use lower case. This can
help to resolve when there are many IOCs and responsibilities for them
are divided amongst several groups, such as at APS.

Learned Friends,
The planned Facility for Rare Isotope Beams, a.k.a. FRIB, is looking to
finalize the naming convention.
The proposed system is an evolution of the SNS convention. I'll list the
format to give an idea of how many uninterrupted characters one might
encounter:
SSSS_BBBB:DDDD_QIIII:TTTTIIIIXXXX
System_subsystem:Devic_Qualifier:Signal Name
One of the remaining questions concerns letter case.
Option 1: Uppercase only.
It's simple; it's unambiguous; it's what we do now.
On the downside, it is hard to read.
Option 2: Lowercase only.
It's as simple as uppercase, but easier to read.
Option 3: Mixed case.
This is best option for legibility.
But it creates ambiguities and can make searching difficult.
Is there something like a community consensus on this?
Are there any pitfalls we should be aware of?
Thanks in advance,
-Mathias
