ChrisW: W3C team is migrating wiki to mediawiki
15:11:07 [JeffP]
... we also want to migrate
15:11:56 [AxelPolleres]
Will the old wiki still be preserved, then no prob, we can migrate other stuff on demand if needed.
15:12:03 [JeffP]
... Proposed: only migrate the active pages
15:14:20 [JeffP]
Harold: will we lose web pages in this way?
15:14:57 [JeffP]
Sandro: It is just a UI, so nothing would be lost,
15:15:12 [sandro]
(it == the 100 page limit.)
15:16:18 [csma]
15:16:24 [JeffP]
ChrisW: There are many good reasons to move over, and now we should identify the web pages that we want to migrate

Two concerns wrt early moinmoin->mediawiki conversion: 1) Loss of version history [currently versions older than 100 steps back are invisible, very likely just a moinmoin parameter]. 2) The wiki-tr tool need to be adapted [give time to try it out in mediawiki].

RESOLVED: For WD2, change structural model so that Forall, Implies, and Atomic are three parallel subclasses of RULE (as shown on Christian's diagram labeled "BLD Rule: alternative")
15:35:07 [Harold]
1) For the choice ' Forall ' Var* ' ( ' CLAUSE ' ) ' we still need to capture in prose that all free CLAUSE variables should be declared in Forall's Var*.
15:35:21 [Harold]
2) For the choice CLAUSE (to the left of the '|') we obtain a duplication of formulas expressible as ' Forall ' ' ( ' CLAUSE ' ) '.
15:35:28 [Harold]
3) For the choice CLAUSE we are also dependent on the Prolog convention.
15:35:50 [JeffP]
ChrisW: What is the new information?

(can we have an email explaining the problem?)

16:03:27 [Harold]
We could also talk here about RIF Dialect Structure:
16:05:58 [csma]
q+ about what Sandro means by RIF document
16:06:23 [csma]
q+ to ask what Sandro means by RIF document
16:07:11 [csma]
ack csma
16:07:12 [Zakim]
csma, you wanted to ask what Sandro means by RIF document
16:11:23 [Harold]
A Horn dialect has somewhat different semantics for a rule P(...) :- Q(...) than an extension with strong negation, where that same rule also 'means' its contraposition ~Q(...) :- ~P(...).

16:17:49 [Harold]
Sandro, as I just reponded to Axel, we could keep the same syntax and construct a hierarchy of semantics (see Michael's lattice diagram).

16:18:32 [JeffP]
... blue arrows, syntactic sugar?
16:18:46 [JeffP]
MichaelK: yes
16:18:46 [AxelPolleres]
I think that the contraposition issue can exactly be addressed with the definition of "loose layering" from Jos, mentioned in this mail:
16:19:17 [JeffP]
MichaelK: frames are syntactic sugar
16:19:34 [JeffP]
sandro: I would like to have cheap and easy syntactic sugar
16:19:57 [JeffP]
MichaelK: we need to think about the scenarios
16:19:59 [Harold]
The semantics of extension dialects can extend the meaning of syntactic constructs in base dialects.

Topic: test cases
16:26:08 [JeffP]
16:26:25 [JeffP]
csma: just a subject that we never discussed
16:26:33 [JeffP]
... Dave did some early work on this
16:27:01 [JeffP]
... maybe we should pick it up again now
16:27:29 [Harold]
We have a three early test cases from the examples of the paper, e.g.
16:28:10 [JeffP]
sandro: a query syntax or see the print result

16:30:21 [Harold]
Actually, we already have a Query language: the BLD Condition Language. Let's use it for test cases!

Jeff, I also agree with the bit about print "action" for PRD.
16:31:39 [DaveReynolds]
+1 to Sandro, all that semantics is part of the dialect
16:31:44 [PaulaP]
one possibility would be to list all facts (data items) entailed by the program
