XIME-P Program
XIME-P aims to be a forum for fruitful
exchanges between the language specification authors, researchers from
the industry and academia, and user communities, around the topic of
XQuery.
XIME-P consists of 3 sessions: Standards,
Industry, and Prototype/Research/Applications. A first component of the
workshop are its high-quality selected papers, reflecting industrial and
research efforts around XQuery. To allow for lively interactions, XIME-P
devotes important time to three panels. The panels will focus
respectively on language issues; industrial support; and perspectives of
XQuery from the viewpoints of database research, user adoption, and
engineering.
XIME-P participants are particularly encouraged to come and voice out
their questions, critiques, comments and concerns along these
directions.
XQuery is getting closer to completing
its first standard. This is an important milestone, comparable to the
SQL86 standard milestone, but the journey is still ahead of us. The
purpose of the XIME-P workshop is to gather researchers and
practitioners from academia and industry together leading to a deeper
understanding of what the research areas should be and what we need to
do in creation of research prototypes and products which will
enable critical applications of XQuery, to propose where we go
from here regarding the language functionality and focus on the XML data
store architectural alternatives.
The workshop has a rich program including two invited speakers,
7 accepted papers,
6 posters, 3 panels, use case studies and demos. A tentative program is
attached.

XQuery: how will the users react?
This talk attempts to
predict the way that users will react to XQuery, once production
implementations are available. What features will they say they like,
what complaints will they make? What will they try to use the language
for, and will they succeed? What are the ten most common mistakes likely
to be? Which will be more significant:
memory-based applications or database applications? To what extent will
the XQuery user community overlap with (or be at tribal war with) other
communities such as SQL users or XSLT users?
The predictions will be based in part on extrapolating from the XSLT
scene. Some of the frustrations experienced by new and not-so-new XSLT
users over the last five years will be shared by new and not-so-new
XQuery users over the next five years, while others will be different -
either because the languages are different, or because the users are
different, or because the problems they are trying to solve are
different.
And how will users play the market? Will they go for the freedom of the
open-source world, or cling to the apron strings of their favorite
database vendors? Will they go for the products that offer the most
features, the fastest performance, or the best standards compliance?
I can guarantee that many of my predictions will be wrong, but I hope
that they will be thought-provoking.
Biography:
Michael Kay started his career in the database field, moving from a
Ph.D. at the University of Cambridge to work as a software developer
with the UK mainframe manufacturer ICL, where over a period of 20 years
he led the design teams on a wide variety of projects including Codasyl,
relational, text, and object-oriented databases. Having risen to the
position of ICL Fellow he decided it was time to return to coding, and
set about the development of Saxon, initially as a feasibility prototype
for a specific customer bid. In quick succession he then wrote the Wrox
XSLT Programmer's Reference book, joined the XSL Working Group in W3C,
left ICL to join the Tamino team in Software AG, became editor of the
XSLT 2.0 specification, joined the XQuery working group, and added
XQuery support to Saxon's growing list of capabilities. Since early 2004
Michael has been running his own company, Saxonica Limited, which
markets a commercial version of Saxon alongside the open-source product,
and provides associated consultancy services.
PANELS
Is it worth doing XQuery research today, and why ?
Organizer: Ioana Manolescu (INRIA)
The
purpose of the panel is to discuss the involvement of researchers from
academia and industry in XQuery research work, and to discuss their
viewpoint on where these research efforts are going.
Some questions to be asked of the panelists are:
* Are (were) you involved in XQuery research ? Why ?
* Would you orient a PhD thesis starting in 2005 on an XQuery topic ?
* Quid of the parallel evolution of industrial product, freelance
implementations, W3C standards, and academia results ? Are they
converging ?
* Which XML data management aspects do you think stringently need
attention ? Are they covered by XQuery ?
Our distinguished panelists are:
* Stefano Ceri (Politecnico di Milano, Italy)
* Don Chamberlin (IBM Almaden, USA)
* Alon Halevy (U. Washington, USA)
* Zachary Ives (U. Pennsylvania, USA)
* Tamer Ozsu (U. Waterloo, Canada)
* Divesh Srivastava (AT&T, USA)
XQuery implementation challenges
Organizer: Fatma Ozcan (IBM Almaden)
Some questions to be asked of the panelists are:
* What are the features
most difficult to implement ?
* What are the query optimization challenges?
* What about indexing?
* What is the existing (early) development feedback ?
* Should feature sets of XQuery and related standards be limited? (one
thing that has dragged these standards for so long is the amount of
stuff in V1
of these standards).
* Is XQuery missing something? (tuples, nested sequences?)
Our distinguished panelists are:
* Eugene Kogan
(Microsoft)
* Kevin S Beyer (IBM)
* George Feinberg (Sleepycat)
* Muralidhar Krishnaprasad (Oracle)
* Till Westmann (BEA)
