Related, yes, but the two are not the same noun.

A user community chooses the choreographies of messages that are to 
be sent between member trading partners in different scenarios.  Each 
choreography defines a profile of using UBL (a subset of its 
elements) and will use a particular configuration of each message 
participating in that exchange.  Sometimes the same profile of a 
message is used in multiple choreographies.

Consider in Europe government procurement (the user community being 
the governments and those who do business with those governments), 
the BII 2 project at http://www.cenbii.eu is defining a new set of 
profiles for messages based on the results of the BII 1 project found here:

  http://www.cen.eu/cwa/bii/specs/

Where you can find the definitions of the profiles in section 4.3 of this PDF:

http://www.cen.eu/cwa/bii/specs/Profiles/DesignDoc/CWA_CEN_ISSS_BII_WG1_ProfileOverview%20v2.pdf

You can see a list of profiles of messages for the choreographies here:

  http://www.cen.eu/cwa/bii/specs/Profiles/IndexWG1.html

Now, I had thought (and have been telling people) that the profile of 
the UBL Invoice in the "BII04 Basic Invoice Only" choreography was 
different than the profile of the UBL Invoice in the "BII19 Advanced 
Procurement" choreography, but a quick look today at that page 
indicates that isn't the case.  Today I see on that page that both 
profiles of Invoice point to BiiCoreTrdm010, without 
distinction.  This surprises me.

Perhaps someone in the BII project who reads this list can cite an 
example of two different collections of elements specified for a 
single UBL document are found in two different profiles.  Or, has it 
been determined in BII that a given UBL document shall have the same 
content constraints (subset) in all profiles where that document is used?

So ... the terminology can be quite confusing.  Certainly the user 
community and the profiles are different things.  However, "profile" 
can be used to refer to the choreography of messages or to the UBL 
document subset used in a given choreography.  Personally, I like 
profile to refer to the subset rather than the choreography, but more 
people feel that the profile refers both to the choreography and to 
the document subset.

Oh, and when you put a bunch of profiles together, as the BII folks 
have done, you have "a UBL customization". So, a user community 
creates a UBL customization containing profiles (choreographies) 
which use UBL document subsets as needed.

I hope you find this helpful.  And I hope someone from BII can add 
their observations as well.
