XOODB - 1st ECOOP Workshop on The Marriage of XML and Object-Oriented Database Technologies and Their Future

In Conjunction with ECOOP 2009

July 6th 2009, Genova, Italy


  • Deadline for submission of both position and technical papers is extended to 24 april, due to the proximity of several other deadlines.
  • Position papers are encouraged, one page long or more. Indeed, in addition to technical papers, there turns out to be a strong interest concerning the current status of OODBs, the origins of this status, their actual future, and the comparison with the evolution of relational DBMSs, XML and others.

Position papers should present a global point of view, possibly sujective (not necessarily technical), that does not usually take place in purely technical papers. Selected position papers will join a round table discussion during the workshop.

We believe such discussion should contribute to allow the workshop to be the place for long term debate, and understanding, in addition to purely technical contributions.

Selected position papers will be included in the formal proceeding published by ACM Digital Library.

Themes and Goals

In the nineties many researchers expected that object-oriented databases would replace the relational ones, just as at the beginning of 2000 XML databases were expected to replace relational ones. The first prediction did not become true as the second one seems more and more to follow the same way. However, many object-oriented concepts and technologies have influenced the management of information both in relational and object-relational databases. For example, extensions have been proposed for the relational model, the query languages, and applications working with data.

The purpose of this workshop is from one side to identify the points for which the relational model is unbeatable to handle XML data, and those for which it is not good enough. From the other side, we wish to discuss interesting object-oriented concepts and technologies that can be successfully applied in the management of XML data, and to discuss future trends in XML data management, either in native or object- relational hybrid models, that can take advantage of developed object technologies. The challenge is thus to set up a strong synergy of OO and XML to solve the issue of the management of data in a heterogeneous environment as the Web.

The goal of the workshop is to bring together academics, practitioners, users and vendors to discuss this challenge, recent achievements, the relevant problems and open issues with the combination of object-oriented and XML technologies in different environments like the Web 2.0, the management of Biological data, and wikis. The workshop will provide the opportunity to debate new issues and directions for research and development work in the future.

Topics of Interest

In order to foster a lively exchange of perspectives on the conference topics, the program committee encourages contributions from both researchers and practitioners. Topics of interest include, but are not limited to:

  • Data models and database design
  • Query and update languages
  • Query processing and optimization
  • Access methods and data structures
  • Authorization and security
  • Data mining and knowledge discovery
  • User and application interfaces
  • Schema updates, versioning and evolution
  • Integration architectures and dataspace
  • Experience using XML and objects
  • UML design and evolution
  • Use of XML and object technologies in biological and collaborative environments
  • Infrastructures for advanced applications (situational applications, mash-up,...)

Workshop Format

The workshop format will be a 20-minute presentation, followed by a 10-minute discussion/debate, led by one of the workshop organizers. We also hope to have one invited keynote session from a distinguished expert. A round table discussion will take place at the end of the workshop to try and draw various threads together, discuss any open issues, conclusions and bring the workshop to a close.

Paper Submission

Workshop submissions must be in electronic form using Portable Document Format (.pdf). Papers should not be more than 8 pages in length. Papers should be formatted according to the ACM proceedings format, using one of the templates listed at the ACM SIG Proceedings Templates web site (http://www.acm.org/sigs/pubs/proceed/template.html). All submitted papers will be judged on their quality and relevance. At least one author of each accepted paper must attend the workshop to present their work.

Submission site is now open!

Paper Publication

Accepted papers will be published by ACM Digital Libraries.
