o variable naming:  string/literal vs. a local URI

currently in RuleML syntax is a string/literal,
we can keep that in the short term for the XML version

disadvantage in RDF view:  don't want to declare a literal
to be a variable for the entire Web universe

local URI is local to a document, e.g., rulebase

Harold:  can view it as defining a separate alphabet of variable names,
local to a document

this requires a change to the working draft of the OWL RuleML document


o other edits on the document

(missed recording some low-level, of which nothing was dramatic)
link near end sect ?2
numbering of examples

want stable W3C namespaces,
e.g., for RDF version and for non-RDF XML version
e.g., Nr:  and Nx:   where N is, say, owlruleml,
or (Harold) swr;
Sandro:  propose swrl and swrlx, pronounced "Swirl"
Sandro is finding out what the W3C process is for getting a namespace



ruleml:_head and ruleml:_body in the non-RDF XML encoding
but change the RDF encoding to use the RDF convention of capitalization:
Harold will do the changes 


we should beef up add to the intro an explanation of 
that it's come from OWL and RuleML, mention DAML more including 
as funder;
also in collaboration with RuleML and with input from SWSI
and ack's to Sandro and others -- in particular Sandro and Pat 
- action:  Ian will tackle doing drafting


authorship (see below)

title, and name of language (see below)


o authorship

adding Benjamin Grosof and Michael Dean

remove authorship by section

add affiliations, make links to home pages not email addresses

Said will do the updates



o name of the overall Rules proposal, and title of document 

Ian:  "OWL RuleML" is a bit of a mouthful; no big axe to grind for "OWL Rules";
of course, when there's a Working Group formed

Said: thanks to Sandro for calling the W3C Working Group draft
"Semantic Web Rules"

Harold:  don't like "Lite"

Benj:  saying both RuleML and OWL gets across that it's a merge and 
a joining forces

Ian:  if "M" is for Meta, is a bit misleading

Harold and Benj:  in RuleML latest thinking (e.g., last Steering
Committee of RuleML Initiative), the "M" is for "Modeling", it never was
"Meta" but rather "Markup"

Benj:  can view OWL RuleML as one point in the RuleML family, IF do think of
RuleML as a family of languages

Sandro:  suggest as name:  
  Semantic Web Rules Language, acronym SWRL pronounced "Swirl"
rest:  we like that!!  

we could call it something like:

OWL RuleML:  

or 

SWRL:  A Proposal for a Semantic Web Rules Language

or 

Combining OWL plus RuleML:  A Proposal for a Semantic Web Rule Language (SWRL)

or 

"A Semantic Web Rule Language (SWRL):  Combining OWL and RuleML" as title


consensus:

- ***"SWRL:  A Semantic Web Rule Language Combining OWL and RuleML"

- we will use swrl and swrlx as namespaces 

- SWRL as an acronym, pronounce as "Swirl"

Benj:  fits nicely in with SWSI ("Swizzie") and SWSL ("Swizzle")

Benj:  we'll soon have the Swirl'd Wide Web :-) 

wrt naming conflicts:  Google search yields nothing uncomfortably
close, there's a swrl.com in storm water resource management

we'll look into getting swrl.org domain name which is currently taken
- action:  Said and Sandro doing this



o doing the W3C Note on SWRL

Sponsors will be MIT (Benj), NRC (Harold), Network Inference (Ian)

Sandro:  refer to it in interim as submitted not as an actual Note til
it's accepted which takes about a month


o plans for OWL-QL 

it's pretty relevant to the push for a RDF Query WG

let's turn it into a note soon, then revisit it technically in light of 
the SWRL proposal, and do a revision on it then



o (some discussion of the charter issues on Rules and also related
aspect of Query charter -- see recent and future postings to the
www-rdf-rules list for people's views)
