Project-Team Presentation

Joint project-team with Université Pierre Mendès-France de Grenoble

The Opéra project focuses on electronic documents: technical documents hypertext, multimedia. Documents models are designed to represent various aspects of documents: logical structure, rendering, scheduling and multimedia contents. Editing and presentation techniques are also developed based on these models.

Research themes

• Adaptable multimedia structured document models
  Models able to represent various kind of documents in a consistant way: structured documents, hypertext, multimedia. Models that allow documents to be adapted to the context (device, user, network bandwidth).
• Structure transformations
  Transformation techniques and tools for XML documents.
• Formatting structured multimedia documents
  Formatting is based on spatial and temporal relationships between objects in a multimedia document.
• Authoring and viewing environments for structured multimedia documents
  Editing tools for multimedia documents taking advantage of a constraint based time model, well suited to incremental consistency checking.
  Viewing environment providing high level services such as temporal navigation, synchronization, network access, due to a predictive-reactive scheduling approach.
• Software
  • LimSee, a temporal editor for SMIL documents.
  • Video-Editor, a framework for editing the structure of video objects and for their integration in multimedia documents.
  • MIP-Phone, a multimedia mail system for 3G phones.
  • i-XSLT, an incremantal version of the Xalan transformation engine.
  • VXT, an interactive environment based on a visual language for programming transformations of XML documents.

International and industrial relations
