Workshop Objectives

By their very nature, Digital Libraries are served by a research community that has been historically heterogeneous and involves scientists from a large number of disciplines. Hence, it should come to no surprise that no agreement exists on the foundations characterizing and governing this broad field; instead, a plethora of models, systems, and methodologies have been developed that are difficult to combine and reuse. Currently the community is well aware of the problems created by such lack of universally accepted frameworks and of the urgency for reversing the situation so that progress may be accelerated.

This is the second workshop in a series aiming at bringing together the international Digital Library community, especially researchers interested in Digital Library modeling and working on the foundations of the field, for intenstive brainstorming and idea exchanging (click here for the First Workshop on Digital Libraries Foundations). Discussions and deliberations will be on several different aspects of the problem and will be in the context of a unified reference model for Digital Libraries. In particular, as a focal point, the workshop will have the Reference Model for Digital Libraries (www.delos.info/ReferenceModel) launched by the EU DELOS Network of Excellence on Digital Libraries (www.delos.info).

The workshop also intends to serve as a vehicle for expanding the set of researchers involved in the formation of the Reference Model, starting from those participating in the meeting itself and continuing on afterwards through appropriate collaborative instruments initiated by DELOS. Increasing the circle of those contributing to this activity will help in consolidating the key concepts in the field and will lead to a comprehensive and universally accepted model, influencing future activities and development of Digital Library systems.


The workshop will focus on the modeling of the main aspects that characterize the Digital Library universe: Content, User, Functionality, Policy, Quality and Architecture. For each one of these, the workshop participants will be asked to outline the specific modeling and research challenges and to identify some of the most promising candidate solutions to address those challenges. Topics of interest include, but are not limited to, the following:

  • (Semi-)Formal Models for Digital Libraries
  • Theoretical Foundations of Digital Libraries
  • Models for Digital Library Resources
  • Models for Information Object, Metadata, Policy, User
  • Digital Library Functionality and Architecture Models
  • Reference Architectures for Digital Library Systems
  • Digital Library and Digital Library System quality models
  • Models of Digital Library Management Systems
  • Evaluation of current approaches in modeling Digital Libraries
  • Digital Library Interoperability Models
  • Concrete exploitations and implementations of Digital Library models
  • Models for Digital Libraries as Collaborative Tools
