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)
