Second International Workshop on XQuery Implementation, Experience and 
Perspectives (XIME-P 2005) June 16-17, 2005

In cooperation with  ACM SIGMOD/PODS Conference 2005


Workshop's goal and interest themes

XQuery getting closer to completing its first standard. This is an 
important milestone and it is comparable to the SQL86 standard 
milestone in the sense that most of the journey is ahead of us. As in 
SQL, it is the application of technology that will shape XQuery. 
Research prototypes and products will play a key role in enabling 
researchers and practitioners in applying and enriching this 
technology. The most significant impact of XQuery will be in the areas 
that query languages such as SQL are not effective and a simple 
translation to SQL is not adequate. Given that XML documents often 
contain text as well as parametric data,  deeper integration of IR 
technology, both from the viewpoint of functionality and system 
implementation, is important. From the viewpoint of content, documents 
in XML repository more resemble HTML pages, where an XML repository 
must handle a huge variety of document schemas, and accept documents 
with new schemas. XML is rapidly becoming the standard for 
representation of information that flows in the internet or internets 
between organizations. XML repositories need to rapidly adapt with the 
evolving schema of the incoming information with no or minimum manual 
intervention. This view is drastically different from traditional DBMSs 
where the schema evolution of the DB is primarily managed by DBAs.

  The purpose of the XIME-P in this workshop is (1) 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, (2) propose where we 
go from here regarding the language functionality, (3) focus on the 
DBMS architecture alternatives.

  XQuery implementation

We believe that discussing, comparing, and envisioning architectures 
for XQuery implementation can be extremely useful for the SIGMOD/PODS 
  Thus,  the XIME-P workshop intends to offer a venue for implementation 
overview papers, which may be more difficult to publish in a standard 
conference, while very valuable in our view. We welcome system overview 
contributions from the industry and academia, characterizing all 
aspects of the system (storage, query execution model, query 
optimization paradigm if any, supported language features etc.) 
Disseminating architectural knowledge and open issues will contribute 
to building a global view of what is currently being done in the field 
of XQuery processing; the progress in language standardization now 
allows  us to compare the usefulness of various approaches, pinpoint 
the technical aspects still unsolved, and envision future (and better) 

XQuery application and experience

In addition to research papers, there is an emphasis on application and 
experience papers. To understand the issues involved in implementing 
XQuery, and the purpose of the various language features, early 
feedback from existing XQuery implementation would be very useful. 
Going beyond simple toy queries, we welcome contributions describing 
XQuery usage, in any possible application context. We are interested in 
exposing the technical advantage of using XML and XQuery in the 
considered application, and in users' experience regarding: language 
features, volume and nature of data managed, types of queries used, 
query processing performance, integration with the rest of the 
information system etc.

XQuery perspectives

  While many have started implementing or using XQuery, the language's 
future is ahead of us. We aim at considering future applications, 
innovative and successful architectures, potential performance 
problems, and promising avenues for future research. We will discuss 
the potential influence of a very complex standard on academic 
research, typically focused on narrower and somehow more limited 
problems; on industrial implementations, driven by customers' needs, 
and on open-source efforts. How to reconcile complexity and ease of 
use? How to optimize the implementation of some language features, 
without hurting the rest? Are there interesting, commonly-recognized 
language subsets? Which will be the "XQuery success stories" in the 
next 5 years?
