<mhausenblas> http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2010Nov/0086.html

mhausenblas: here is a link to a discussion between ericP, betehess, you...
... regarding set vs multiset

... I'll look at that that

<mhausenblas> http://www.w3.org/2001/sw/rdb2rdf/track/issues/

juansequeda: ok to check an action on this issue

mhausenblas: ok to split in many issues
... and one on the multiset issue
... so we can speak about that next week

betehess: please use the ML so we can help you :-)
... especially because ericP and I initiated the thread

juansequeda: will do

AOB

<mhausenblas> http://www.example.com/r2rml?string=Paris

juansequeda: I would like to speak about hhalpin email
... we raised this topic a long time ago
... as the input will always a string
... how to deambiguite
... I'm curious to know what people think about it
... maybe a solution or an idea?

mhausenblas: if you have a string, you have to make sure that these URIs match their expectation

@@: I believe it's another topic

scribe: out of the scope of this group

juansequeda: I agree
... "it's your problem"

mhausenblas: ok but how can we formalize that?
... as we have to come up with a solution easy enough
... like in term of expectations
... I don't know, but it's part of the challenge there
... it's in the charter

@@: maybe with user defined functions that output in RDF?

juansequeda: with the function call approach, you may have a problem with the reverse function needed for SPARQL for example
... if you search about a specific URI

<mhausenblas> Michael: I'm happy to take an action on this to review existing approaches incl. DBpedia and Uberblic lookup, Triplify way, OKKAM, etc and report on the options via the Wiki

juansequeda: so it may need to work both ways

mhausenblas: it makes sense that I take an action on that
... and see what people out there actually do
