Real world contextualization.  

You are bidding a contract for a 
project governed by a set of standards or 
specifications.  An example might be to 
produce a new system for your government, a 
large systems integrator, etc.  The bidding 
results in a contract which is the overall 
governing record of authority for the project 
scoped by time and other considerations such 
as payment for performance.  The standards or 
specifications internally cite other documents 
such as a DTD or schema family for the documents 
and other data items to be delivered at specified 
intervals of project time (eg, by phase) or 
clock/calendar time (by date).  Note that these 
time types scale.   During the negotiation, the contract 
procurement officer and your contract officer 
agree to waive specific requirements in specific 
governing documents.   They also agree that during the 
performance of the project, authorities representing 
all parties meet at scheduled times (either project 
time or clock/calendar time) to review the 
project deliverables and if necessary, to renegotiate 
the conditions of the governing documents and make 
agreed upon adjustments.

That is real world contextualization for which 
you will receive real world money.  The description 
above is slightly simplified because the collection 
of information exchanged during each negotiation must 
be accounted for (traceability).  Part of the solution 
is how you distribute RDDL since it is essentially a 
Contract Data Requirements List or CDRL.  CDRLs cite 
DID (Data Item Descriptions).

Your challenge is to use URIs to represent all of the 
above and not open your company up to litigation 
based on charges of fraud, misconduct, failure to 
deliver, and so forth.  Further, you should be able 
to prove by URI that your company has bettered the 
performance contracted to receive incentive payments. 
In some cases, you must be able to drop deliverables 
if they have been traded for new requirements discovered 
during the course of the performance.

Real world: contextualization by control and feedback. 
So called "hotspots" in the system are a symptom of a 
problem you can easily solve as long as the name is not the 
thing.

Ah... Sorry. Thought you'd caught the start of the thread...

c15n is short for Contextualization. It's a concept whereby
a URI is resolved based on some locally defined set of context.
In academic research it could be based on research appropriate
copies (edition 1 vs edition 2, photograph vs digitization, etc).
In the cases we have been talking about here it means taking
some URI and resolving it based on your localized concept of
what that URI identifies (i.e. you think you have a better XML
Schema than the owner of the original, you have some locally
cached copy, you don't trust the holder of the URI to not change
the bit of XML underneath you, etc)....
