<LeeF> nice name
<SimonR> Weird, I'm getting a busy signal from Zakim.
<LeeF> That is quite weird...
<LeeF> OK, sorry SimonR :(
<SimonR> It's a credible excuse to dodge scribing duties. :)
<ericP> doesn't work -- i still hear the hum

<chimezie> (1,2,3,4,5)
<chimezie> ((((1+2)+3)+4+4)
chimezie: looked at algorithm in
step 4 of 12.2.1 and tried to enumerate algebra constructs that
arise from it
... use a fold function to go from every combination of a left
and right argument to 20 algebra expressions
... idea would be to first list every permutation and then see
which tests cover each
<ericP> Join(LeftJoin(BGP(..),{ .. }),LeftJoin(BGP(..),{ .. }))
ericP: I don't see a problem expressing these as XPath's against a parse tree
<ericP> ASK { ?s ?p ?o OPTIONAL {} OPTIONAL {} )
<ericP> }
ericP: express each of chimezie's
patterns as a query
... look at XML from each and see how many [test?] queries
there are like it in the respect we're looking for
<ericP> ASK { ?s ?p ?o OPTIONAL { ?s2 ?p2 ?o2 OPTIONAL { ?s3 ?p3 ?p3 } } }
<ericP> ASK { OPTIONAL { ?s2 ?p2 ?o2 OPTIONAL { ?s3 ?p3 ?p3 } } }
<ericP> ASK { OPTIONAL { ?s2 ?p2 ?o2 } OPTIONAL { ?s3 ?p3 ?p3 } }
<ericP> ASK { {} OPTIONAL { ?s2 ?p2 ?o2 } OPTIONAL { ?s3 ?p3 ?p3 } }
<ericP> http://www.w3.org/2005/01/yacker/uploads/SPARQL
