Hi Pablo,
if you were talking XML or other such unreadable stuff I agree. But the
whole point of context free grammars like programming languages, ADL,
OWL, and also these SNOMED mini-languages is to be formal and human
readable. It is via languages that humans learn the semantics of the
formalism in a native way. The problem with GUIs is that everyone's is
different, whereas everyone knows what this means (using standard logic
as an example):
∃p:P | F(p) = blue
I think that the SNOMED compositional and constraint grammars have a
very readable and concise native syntax, and the fact is that people
edit archetypes and related artefacts all the time, so we need to be
able to see this kind of syntax in plain text.
I now think that putting these expressions into URIs is not the way to
go. We could probably handle the constraint in a separate ODIN
attribute, in the way that Bert is probably thinking about. I'll try to
work on a design for this as soon as possible, but others are always
welcome to come up with something.

Not sure why readability is a requirement here. Shouldn't those
expressions be generated and consumed by systems?
We should create simple to use GUIs not simple to read code :)

Or just use the "Long syntax" as described in point 5.2 from
Expression Constraint Language, which keeps things readable enough

Daniel,
my fault - didn't read the front page properly - the things we
need are mooted for next release. But now I agree with Diego...
The expression constraint "< 404684003|Clinical finding|: <

<http://snomed.info/ecl/%3c404684003:%3c%3c47429007=%3c%3c79654002>
that is seriously unreadable. In a different universe, we
would have hoped for something like:
http://snomed.info/ecl/<404684003:<47429007
<tel:4742%209007>=<79654002
but of course that is illegal in URI syntax.
