Subject: [legalxml-courtfiling] Globally unique identifiers - approach

John 
and all,
 
At the 
New Orleans meeting I agreed to propose an approach to generating globally 
unique identifiers. After searching around on this topic I would like to 
recommend using UUIDs as per the IETF DRAFT RFC. This approach requires NO 
global coordination.
 
Please 
see:
http://www.ietf.org/internet-drafts/draft-mealling-uuid-urn-05.txt
 
 
This 
RFC is currently in draft status and is based on Unique ID generation 
technique used in Open Software Foundation's Distributed Computing 
Environment. The RFC guarantees that ID's generated using the 
recommended algorithms will be unique across 
space and time.
 
This 
RFC specifies 4 algorithms to generate universally unique ID's.  The 
following subset is recommended for LegalXML 
standards:
 
  
1. System timestamp up to a 100 nanoseconds
 
  
2. MAC address of the machine where UUID is generated
 
  
3. Use of Random or pseudo random numbers
 
 
Finally, the RFC contains C code sample on how to generate UUID's based 
on the generation algorithms listed above. 

Please 
let me know what you think and how you would like to see this phrased within 
Blue.
 
Regards,
james
