[Insight-developers] [Fwd: Your UID prefix from Medical Connections]

[Stephen R. Aylward]

Wow - they're fast....the ISC's UID is given below...

As Dr. Clunie said, we are obligated to make sure each suffix is 
unique...or I may go to jail or spend an extra year in purgatory 
or...hmmm, they're kind of unspecific on it...and guessing about how 
some dicom databases operate, it probably is quite important.

To make suffixes unique...are some machine's random number generators 
tied to GMT?   If not, perhaps a long random number appended to GMT at a 
resolution of a 1/100th of a second is a good suffix.

Assuming that we don't want to get into trying to manage/delegate 
sub-ranges of suffixes, I don't think we should make it easy for the 
user to modify a suffix since they might succumb to the impression that 
if they use 1234 then they would certainly not conflict with anyone else...

Dear Stephen R. Aylward,

I have pleasure in enclosing your UID prefix as promised.  It is:

1.2.826.0.1.3680043.2.1125.

You are hereby granted full permission to use this UID prefix as your own
subject only to the following minimal conditions:

1) You agree to operate a policy to ensure that UIDs subordinate to this
prefix cannot be duplicated.

2) You may sub-delegate ranges using your prefix, providing this is either
on a not-for-profit basis, or as part of another product.
      i.e. you may not sell numbering space itself

I hope that this facility is useful to you, but you have any questions,
please ask.

Yours sincerely

David Harvey
Medical Connections
