WAM is a research project-team of INRIA Grenoble - Rhône-Alpes and LIG, created in January 2003 as a follow-up of project Opera.
Project WAM aims at making it easier to develop and use rich multimedia contents and applications on the web. Particular attention is paid to documents and applications that tightly integrate different types of media objects, discrete (text, images, equations) or continuous (video, audio, animations). Multimedia resources are distributed, linked together, and use platform-neutral formats, which make them usable by anyone through different kinds of terminals and networks.
Research
In this perspective, WAM addresses three key issues:
- Multimedia document models and formats
- Models and formats used for sharing multimedia content on the web must represent the many facets of multimedia documents. Their richness and versatility determine how multimedia content can be processed and used in various contexts.
- XML processing
- XML is the ground on which web multimedia formats are built. It is therefore crucial to better understand how XML structures can be handled, and what are the theoretical tools that may help to develop an effective framework for processing XML structures.
- Multimedia authoring
- Authors of multimedia documents and applications need help from specialized tools to benefit from the many, complex possibilities offered by web formats. Methods used for static, textual documents do not work for dynamic multimedia web resources. New approaches have to be developed and experimented.
More details are available in the team annual report (xml, html, pdf).
Software
WAM develops software tools to support this research activity:
- Amaya
- An Open Source web editor developed jointly with W3C to ease editing, publishing and sharing complex web pages containing text (in HTML, XHTML), graphics (in SVG) and mathematical expressions (in MathML), with style sheets (in CSS).
- LimSee3
- A multimedia authoring tool that aims at flexibility and easiness of use through an advanced multimedia document model based on templates.
- XML Reasoning Solver
- A tool for the static analysis of XPath queries and XML schemas based on the latest theoretical advances. It allows to solve many fundamental XML problems such as satisfiability of XPath expressions in the presence of XML schemas, containment and equivalence of XPath expressions, and many other problems that can be formulated with XPath expressions and schemas (DTDs, XML Schemas, Relax NGs).
- LibA2ML
- A library for importing, editing and exporting documents in the A2ML audio format.
