Presentation
This project is interested in electronic documents, such as technical documentation, hypertext, and multimedia. It studies document models that take into account logical structures, graphical presentation and multimedia contents. It also develops editing techniques based on these models. OPERA is a project ofthe research unit Rhône-Alpes of INRIA.
Project Opera was closed at the end of 2002. Some of its activities are continued in project WAM.
Topics
- Models for multimedia structured documents
- Models that can represent different types of documents in a homogeneous way, including structured documents, hypertext and multimedia. A major activity in this area concerns transformation techniques required for XML structured documents. Another activity focuses on the specification of generic models for multimedia documents.
- Edition/presentation of multimedia documents
- Authoring and presentation environments for multimedia documents based on a representation of time well adapted to an incremental verification of temporal scenarios.
- Cooperation on the Web
- Cooperative document editing and the impact of new web technologies for the emergence of cooperative tools on the web.
Software
Current project
- Kaomi
- A toolbox for creating authoring environments for multimedia documents
- Madeus-Editor
- An authoring environment for multimedia documents specified with flexible relations.
- SMIL-Editor
- An authoring environment for multimedia documents specified in the standard SMIL1.0.
- Mdéfi
- An authoring and presentation environment for multimedia documents in which the internal structure of complex media such as video can be edited to be used inside spatial and temporal synchronisations in the document.
- LimSee
- A temporal editor for multimedia documents specified in the standard SMIL1.0.
- PocketSMIL
- An embedded SMIL player written in C++, well suited to PDAs and other mobile devices.
Previous projects
- Thot
- a structured document editor, used for a number of experiments such as active documents, embedding complex physical structures in logical structures, transformations of logical structures, Web editing, etc.
- Byzance
- a cooperative structured editor
Utilities
- MathMLC2P
- An XSLT transformation which translates MathML 2.0 content markup into Presentation markup
W3C at Inria Rhône-Alpes
The project OPERA has close relationships with the W3C Inria Rhône-Alpes team. The W3C browser/editor Amaya is based on the Thot toolkit.. More Information
