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.
- 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.
- 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.
