• F2F9

ILOG hosted F2F9 in Gentilly, France, on Thursday and Friday 21-22 February 2008

Outcomes

See Minutes.

Scheduled next PWD release of BLD, SWC, and FPWD of FLD & DTB for March 21.

• RESOLVED: Create a new Document with provisional title "Data Types and Builtins" to contain elements common to all dialects with Harold and Axel as editors.
• RESOLVED: make "specialization of FLD" sections (of BLD) appendices, leaving standalone sections in place, and making both standalone and specialization normative.
• RESOLVED: make argument names distinct.
• RESOLVED: We keep named arguments, explaining in BLD that: A RIF consumer that does not support named arguments can implement them, with relative ease, by treating them as positional arguments (of a different predicate, formed in a stable but implementation-dependent way) in the lexical order of the argument names. (Closing ISSUE-44).
• RESOLVED: No reification in BLD. This is like WD1, except no nested frames. A change from 18-Feb draft: Equality, frames, subclass, membership are no longer terms.
• RESOLVED: (Approach 3) Functions on error return an error element that is in the domain. BLD Spec does not require that predicates return F on error, just that they have a truth value. BLD spec recommends using guards with builtins, to give predictability. Without guards, rules may behave unpredictability on error.

Agenda

Location, direction and hotels

Please fill out the Registration Form, even if you are not coming.

Meeting Location

• at ILOG's HQ, 9 rue de Verdun, 94250, Gentilly
  • If you are lost, call the desk (01 49 08 35 00)

  • Check ILOG's page on location, direction and hotels

Public transportation

• Go to the RATP web site for directions to go by public transportations from any place to any place in Paris and surrounding.

  • Look for the small flags on the upper right corner for versions of the site in english, dutsch, german or spanish.

Hotels

• ILOG has negociated rates with the following hotels:

  • Holiday Inn Express: 84 €/night breakfast included

  • Across the street from ILOG

  • Location and access:

    • that one is at Porte d'Italie!

    • look at the transportation page on the hotel web site

    • the closest subway and tramway stations are: PORTE D'ITALIE

  • Novotel Porte d'Italie: 114 €/night + 14 € breakfast

  • More upscale than the Holiday Inn express, but a 0.5 miles walk from ILOG

  • Access and location:

    • look for the access and location button on the hotel's web site (bottom of the left bar);

    • the closest subway and tramway stations are: PORTE D'ITALIE

  • Holiday Inn Express Place d'Italie: 103 €/night breakfast included

  • 1.3 miles walk from ILOG or take bus 57; the big difference is that this one is intro muros - which means subway to dowtown

  • Access and location:

    • that one is at Place d'Italie, which is a different place than Porte d'Italie...

    • look fat the access map page on the hotels web site

    • the closest subway station is: PLACE D'ITALIE

• How to book a hotel with ILOG's negociated rate: send an email to Sabrina Seegoolam with your personal information and your arrival date and time and departure date and the hotel you want (if you choose one). Be sure to mention that you are coming for "W3C RIF WG F2F9". Sabrina will handle the booking and send you the confirmation. You may be asked to pay upon arrival at the hotel.

• Comment from Hassan: The hotels mentioned above are standard aseptic beehive-like American-style hotels that are situated in not so pretty areas (e.g., the Holiday Inn Express has a view on the Paris "Boulevard Périphérique" freeway and a garbage-dump site!). For those who are interested in a cheap and picturesque hotel (i.e., decent but not fancy amenities in the 55-65 euros range) where I myself stay every time I visit ILOG Paris, look up Hotel Verlaine. Again, nothing fancy, but clean and family-run, and in a very nice "quartier" (neighborhood) of Paris called La Butte-aux-Cailles. It is located on the 57 Bus Line that goes directly to ILOG (an 8-min ride). For those who wish to use their legs, it is also a pleasant and leisurely 20/25-min downhill walk to ILOG. Important Caveat: The number of rooms in Hotel Verlaine is small (20, and only 15 of them having showers or baths, the others having just a sink and wc). There are many other hotels of this sort in Paris that are easily reachable by underground and/or bus. Just look up Internet: if in doubt about what you find or if you wish to know about neighborhoods and/or transportation to/from ILOG, send me mail.
