Subject: NYC LOCAL: LXNY Meeting Tuesday 4 January 2000: Philip Wadler will speak on XML and Lisp
Date:
Message-ID: <84r2vt$gsp$1@panix7.panix.com>
<personal>
If you like any of the *ml+tags-which-do-something systems, whether your
favorite system is source secret or free, this meeting is for you. Lisp
is based upon two simple ideas:
1. Data and programs are organized into trees, just like *ml.
2. You must systematically distinguish between the thing and the result of
evaluating the thing, but both are first class objects.
The extendo-tag systems folk already do 1, and they are in process of
discovering the advantages of 2.
</personal>
LXNY will next meet on Tuesday 4 January 2000 in the IBM building
at 590 Madison Avenue on the Island of Manhattan.
This meeting is free and open to the public.
In particular, all members of FUNY, NYLUG, LUNY!, AnyNIX, the Brooklyn
Bunch, and all other Free Software Groups are welcome!
The meeting starts at 6:30 pm and runs until 9:00 pm. Enter the building
on the corner of 57th Street and Madison Avenue and ask at the front desk
for the room number.
At exactly 9:00 pm many members will repair to our traditional place of
refreshment.
Philip Wadler, of the Functional Cabal^W^W^W^Wserious compiler and
categorical hacker, one of the designers of Haskell, the pure, lazy,
functional programming language with monads for input/output, member of
the W3C XML Query working group, late of Glasgow University, now at
Bell Labs of Lucent, will speak at this meeting.

The subject will be XML and Lisp:
<blockquote from="http://cm.bell-labs.com/cm/cs/who/wadler/topics/xml.html">
The Next 700 Markup Languages
Philip Wadler. Invited Talk, Second Conference on Domain Specific
Languages (DSL'99), Austin, Texas, October 1999.
XML (eXtensible Markup Language) is a magnet for hype: the successor to
HTML for Web publishing, electronic data interchange, and e-commerce. In
fact, XML is little more than a notation for trees and for tree grammars,
a verbose variant of Lisp S-expressions coupled with a poor man's BNF
(Backus-Naur form). Yet this simple basis has spawned scores of
specialized sublanguages: for airlines, banks, and cell phones; for
astronomy, biology, and chemistry; for the DOD and the IRS.
Domain-specific languages indeed! There is much for the language designer
to contribute here. In particular, as all this is based on a sort of
S-expression, is there a role for a sort of Lisp?

Upcoming Events:
The next LinuxWorld Expo will be held at The Javits Convention Center
1 February through 4 February 2000. All who run any free OS, no matter
what kernel, are welcome. Those who still use a source secret OS in their
business should come to this educational event.

We do not yet know the exact date of the next Refund Day, but it will be
held some time before 2 February 2000. The refund clause of the End User
Licensing Agreement used by most vendors of IBM style peecees is still
not honored by many of the large vendors. This will shortly be
corrected.

LXNY will meet regularly the first Tuesday of each month at IBM
throughout 2000. LXNY and its supporters thank IBM for the donation of
this meeting space. LXNY also thanks those who, inside and outside of
IBM, worked in favor of this gift.

Add:
CL-HTTP, the Common Lisp Hypermedia Server
http://www.ai.mit.edu/projects/iiip/doc/cl-http/home-page.html
The latest version (70.23) has an XML parser in
its contrib directory:
CL-XML is written by James Anderson and Benno Biewer.
From its documentation:
we have implemented a primitive "processor" in common
lisp for data streams serialized according to the
"extensible markup language" standard. this document
provides a cursory introduction to xml, describes the
implemented parsing/processing mechanism for CLOS-based
applications, and explains how to use the processor.
the processor is intended both as an extension to the
cl-http server and as a stand-alone xml interface. the
runtime environment is examined during the loading
process to determine if the if http support is already
present. if so, then the existing facilities are used
and server extensions are generated to support xml.if
cl-http is not present, then these extensions are not
loaded and only file streams and primtive http streams
are supported.
the xml processor reads a marked up data stream to
produce a document object which binds definition
information and element content. the respective class
definitions include support for access to definition
and content data and for document serialization.
additional utilities are included to
instantiate and serialize instances of arbitrary
specializations of STANDARD-CLASS from and to an xml
representation.
offer an element interface to record-oriented data (mcl
3.*, 4.*; allegro 4.3), thereby offering an uniform
interface to "ascii" and "binary" data.
several demonstration files are included, among them an
example of document and element serialization is
included which presents documentation for several
common-lisp data classes (function, generic-function,
symbol, standard-class) as xml or html, depending on
the browser capabilities.

Did you actually mean specialization of STANDARD-CLASS (class
definition, GF etc.), an intance of it or both? (It's cool either way.)
