I think mixed case is the best.

You want to ensure proper notation that is strict. E.g. what to use instead of a space? Just skip it or use underscore?

If everyone follows it then there will be no ambiguities or problems with search

 

Unfortunately we at SNS didn’t follow it very well and now we have PV names like:

DTL_Diag:BLM130:MPS_Trip_limit_Rad

 

Instead of

DTL_Diag:BLM130:MPSTripLimitRad

or

DTL_Diag:BLM130:MPS_Trip_Limit_Rad

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,
