Hi all,

I personally agree with Alasdair position that each profile should 
define fixed URIs not only for types but also for properties => +1
The main reason is that, at some point, fostering interoperability 
requires to make choices. Even if, later one, these choices turn out not 
to be the best. But this is why Alasdair's proposition also suggests 
version contexts, which is totally needed I think.

Yet, I understand Melanie's point, and here are a few elements that, in 
my opinion, suggest that there is no real conflict:
1. Although each group would define fixed properties URIs, a data 
producer can still add properties of their choice. Freedom of choice is 
safe.
2. In case of disagreement about which property URI should be selected 
in a profile, the cardinality (minimal, recommanded, optional) might 
help in accommodating this disagreement: e.g. instead of one minimal 
property URI, the group may recommend several optional or recommended 
URIs, although this would not be the best solution, I agree. Mappings 
suggested by Michel would probably be a better move in this respect.
3. Nothing is fixed forever, whenever the community deems this 
necessary, a new profile version can be created with updated properties 
URIs.
4. Mappings, as proposed by Michel, are a way of dealing with multiple 
vocabularies. Although here again, mappings come with serious 
maintenance concerns: who decides the equivalence between 2 URIs 
(different communities may have different perspectives or see subtle 
differences etc.), who maintains the mappings, how are they versioned, a 
profile version should refer to a mapping version, etc.

Franck.
