[NeXus-committee] NeXus definitions tidy up and versioning

[HAUSER, Nick]

Hi Freddie,

The resolutions as I put in my notes from the Berkeley meeting (not minuted)
1. All base classes are ratified
2. All base classes require 'housekeeping' (ACTION: technical subcommittee)
3. All base classes to be tagged 2.0 after housekeeping (ACTION: technical
subcommittee)
4. All ratified instrument definitions to be tagged 2.0 i.e. NeXus version
include base classes and instrument definitions.

Removing NX prefix:
I second the proposal.
I would like to see the proposal extended to done before 2.0 is released.
I move that the naming proposal goes to vote and is incorporated in task #2
above. 

Website decommissioning:
I second the proposal and move that it goes to vote.

European spelling:
This is not minuted on the site. 
I agree it should be consistent. Note that udunits uses American spelling.  
The proposal could read, 
Language should be consistent, and use the w3c convention
http://www.w3.org/International/articles/language-tags/Overview.en.php e.g.
lang="en-US" or lang="en-GB". 
The default to be "en-US". 
Let's run a discussion then vote.

Note: 
Bragg could help with the 'housekeeping' by programmatically generating
NeXus classes with validation to ensure consistency.

Regards,

Nick.
