Agenda & Minutes

F2F10_Minutes

Resolutions

Day 1
  • RESOLVED: BLD will include Conjunction in the rule head (the "then" part)
  • RESOLVED: remove language about all the subtypes of xsd:string being required
  • RESOLVED: DTB will provide the menu of datatypes and builtins which dialects can use, by reference, when they state which datatypes and builtins must be supported by implementations.
  • RESOLVED: add xs:dayTimeDuration and xs:yearMonthDuration, but NOT duration, to those required in BLD (and of course DTB), as in http://www.w3.org/TR/xquery-operators/#dt-yearMonthDuration
  • RESOLVED: add builtin predicates to BLD and DTB: pred:numeric-less-or-equal, pred:numberic-greater-or-equal, pred:numberic-not-equal (they amount to shortcuts, to avoid disjunction).
  • RESOLVED: Publish DTB as a FPWD once changes decided so far today are made (and reviewed by Chris)
Day 2
  • RESOLVED: remove aliases for symbol space identifiers in RIF
  • RESOLVED: modify Presentation Syntax to include "Const ::= STRING" (allowing "chat" as short for "chat"^^xs:string).
  • RESOLVED: add xsd:double as a required symbol space
  • RESOLVED: reuse NumericLiteral from SPARQL http://www.w3.org/TR/rdf-sparql-query/#rNumericLiteral giving us INTEGER, DECIMAL, and DOUBLE to the Presentation Syntax
  • RESOLVED: modify presentation syntax so that alphanumeric identifiers starting with "_" are shortcut for rif:local (so _foo is short for "foo"^^rif:local)
  • RESOLVED: Adopt SPARQL convention for using backslash to allow quotes (and cr, lf, tab, etc) within quoted strings (in Presentation Syntax).
  • RESOLVED: Close Issue 56 as addressed by the resolutions this morning.
  • RESOLVED: Publish SWC as LAST CALL Working Draft, after changes agreed upon this session and yesterday are made (and checked by CSMA)
  • RESOLVED: Close Issue 49 with decisions made so far today
  • RESOLVED: Close Issue 54 with at-risk label as decided this morning.
  • RESOLVED: Close Issue 60 as decided this morning -- if they are incomparable it's an error
  • RESOLVED: Answer to Dan is that in BLD, pred and funcs have one arity, and it is correct that the restriction holds even across multiple documents. So the requirement is met -- rulesets can be merged -- but if one ruleset is in error, then the merged version will be able to detect the error.
  • RESOLVED: in the RIF XML syntax (as long as we stick with this non-RDF style), attributes will have no namespace (be unqualified) (so that we can avoid "rif:" in documents)
  • RESOLVED: Change External(ATOMIC) to External(Atom) or External(Frame) and add text explaining how External frames are supported by the semantics.
  • RESOLVED: accept the conformance statement on http://www.w3.org/2005/rules/wiki/Conformance for BLD, up to the separator line.
  • RESOLVED: we'll have an XML such that RIF can operate on RIF documents at a RIF-syntactic-level instead of a DOM level. Requires something like numbering arguments or rdf:parsetype="collection" or ordered="yes".
  • RESOLVED: use an XML attribute rif:ordered="yes" (as exemplified above) or using an equivalent unique method to specify order, which works like rdf:parseType="Collection" (and rif:type attribute gets qualified again.)
Day 3
  • RESOLVED: Close Issue 34 as addressed by text currently in BLD at http://www.w3.org/2005/rules/wiki/BLD#Conformance_Clauses
  • RESOLVED: RIF will use rif:ordered="yes". This item will be marked "at risk", saying the name and XML details on this bit may change.
  • RESOLVED: Adopt the XML syntax for metadata in http://lists.w3.org/Archives/Public/public-rif-wg/2008May/0036.html and given as the first example on http://www.w3.org/2005/rules/wiki/Metadata_examples, using conjunction-of-frames instead of all formulas.
  • RESOLVED: the <id> and <meta> elements can occur under any Class element (this matter is underspecified in 0036, and previous resolution).
  • RESOLVED: Close Issue 51 (metadata syntax and rule identification) give the decisions made so far this meeting.
  • RESOLVED: Close Issue 58 (Comments) by suggesting people use Dublin Core, RDFS, and OWL properties for metadata, along the lines of http://www.w3.org/TR/owl-ref/#Annotations -- specifically owl:versionInfo, rdfs:label, rdfs:comment, rdfs:seeAlso, rdfs:isDefinedBy, dc:creator, dc:description, dc:date, foaf:maker. This goes in BLD (near where the metadata syntax goes).
  • RESOLVED: close Issue 55 (striping and xml syntax and rdf/xml syntax compatibility) addressed by decisions made so far this meeting
  • RESOLVED: move Issue 57 (xml syntax extensibility) out of critical path
  • RESOLVED: We say metadata SHOULD survive the translation from-and-back-to RIF
  • RESOLVED: close Issue 59 as discussed in this meeting
  • RESOLVED: In Presentation Syntax, the IRIs in rif:iri Consts can be relative.
  • RESOLVED: We'll use XML 1.0 as amended http://www.w3.org/TR/xml (not XML 1.1) for the XML syntax for BLD.
  • RESOLVED: make equality-in-the-head a feature-at-risk.
  • RESOLVED: Mark "at risk" the strictness part of the conformance clause
  • RESOLVED: Advance BLD to Last Call, pending satisfactory completion of the edits decided at this meeting.
  • RESOLVED: Publish PRD as a FPWD, given the editorial changes decided so far this meeting (after confirmation of edits by Gary and Adrian).
  • RESOLVED: The WG requests a 1-year extension, with the work plan/description http://www.w3.org/2005/rules/wiki/Extension_Request_2008
  • RESOLVED: conditional on reviews by Jos and Chris, publish FLD as 2cnd WD

Facilities provided

  • we will provide lunches, 2 coffee breaks per day and a social dinner (this is estimating around 15 attendees)
  • internet connection and call-in facilities will be provided

Hotels/Accomodation

  • You find several Hotels recommended by NUI Galway at http://www.nuigalway.ie/procurement/internal/contracts_awarded.html (check the distance to DERI before!)
  • The closest and most convenient Hotel (right across the street) is Westwood House Hotel. We have an agreed corporate rate from NUI Galway with Westwood hotel at 89 EUR per night. Reservations can be made calling there and referring to that you are visiting NUIG requesting the special rate, or via our secretary: Hilda Fitzpatrick.
  • Glenlo Abbey is also very close to DERI (and has a nice golf course :-) ).
  • For ones happy with a friendly and nice B'n'B (nothing fancy, but walking distance from DERI), I recommend Abbey House, which has reasonable rates, clean rooms and an incredible Full Irish breakfast (number of rooms limited, though).

Getting there and away

  • AerArann flies directly to Galway airport from Dublin and several UK destinations. AerArann also opened a new route to Amsterdam 4 times weekly, starting from May!
  • Shannon Airport is the next bigger airport, offering direct flights from the US for New York, Boston, Chicago, for example.
  • Flights to Dublin Airport require you to travel onwards either with AerArann (see above), bus, or train.
  • Buses between Dublin or Shannon and Galway operate by CityLink, NestorLink, or Bus Eirrann
  • Travelling by train from Dublin to Galway (Timetable 2008, PDF) is not recommended unless you want to stop over in Dublin city, since reaching Dublin Heuston Station from Dublin Airport is not necessarily convenient, although the train is faster than the bus in general, if you are already in the city.
  • As for local transport, a reliable Taxi company is Big-O-Taxis, telephone number: +353 (0) 91 585858
