2. International Cooperation ProTeM-CC/INRIA Title: Conception of Cooperative Multimedia Edition Environment for the Web with Technology of Workflow Coordinators: José Valdeni de Lima Nabil Layaïda

3. Components of the system 1 – Synchronization Multimedia Tools 2 – HTML Editor 3 – HTTP Server 4 – Annotation Server 5 – WebDAV extensions 6 – Workflow Engine 7 – Framework BW (Big Watcher) today future

5. 1 – Synchronization Multimedia Tools SMIL The Synchronized Multimedia Integration Language enables simple authoring of interactive audiovisual presentations. SMIL is typically used for "rich media"/multimedia presentations which integrate streaming audio and video with images, text or any other media type. [www.w3.org/AudioVideo/]

6. 2 – HTML Editor Amaya Amaya is a browser/authoring tool that allows you to publish documents on the Web and comes equipped with a "WYSIWYG style" of interface, similar to that of the most popular commercial browsers. With such an interface, users can easily generate HTML and XHTML pages. [www.w3.org/Amaya/]

7. 3 – HTTP Server Ex.: Apache A well configured server HTTP, which includes the methods PUT, POST, GET, would make it possible the group to publish its Web pages. [www.apache.org]

8. 4 – Annotation Server Annotea Server Annotea is a project enhancing the W3C collaboration environment with shared annotations. By annotations we mean comments, notes, explanations, or other types of external remarks that can be attached to any Web document. [www.w3.org/2001/Annotea/]

11. 5 – WebDAV extensions WebDAV • WebDAV stands for "Web-based Distributed Authoring • and Versioning". It is a set of extensions to the HTTP • protocol which allows users to collaboratively edit and • manage files on remote web servers. [www.webdav.org]

12. 6 – Workflow Engine Workflow The automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant* to another for action, according to a set of procedural rules.*participant = resource (human or machine) [www.e-workflow.org/]

13. 7 -- Framework BW (Big Watcher) BW BW is one framework to give has supported past events awareness...To supply the context of the individual activities through the understanding of the activities carried through for the others. [gnome.inrialpes.fr:1959]

14. BYZANCE A Web based HTML cooperative editor The Byzance groupware application allows users connected to the Internet to collaborate for producing shared documents in HTML format We use this tool to analyze all its cooperative edition flows and to extract a model of Workflow based on methodology WIDE of Casati& Ceri [www.inrialpes.fr/opera/Byzance.en.html]

15. Why WIDE? capacity to represent any type of WF access specification the external BD facility to make modules of tasks clearly and full formalism for specification of tasks handling of exceptions [Glaucia 00]

16. Problems the definition of actors and roles to be made in informal way temporal aspects and dynamic data Solution use of templates [Glaucia 00]

17. task supertask multitask k beginning/end direct connection join interactive fork total/ join total k fork conditional with mutual exclusion fork conditional join parcial

18. Item Characterization of de task Supertask Name of task Description Pre-condition Post-condition Agent

19. Workflow Engine Workflow Authoring workflow for the creation of the documents (course) Workflow of Execution workflow for the execution of the course

20. Workflow Authoring cooperativework roles ( author,collaborator, visitor,...) different rights ( owner, write,read,..) datetime (occurs of a specific date and time) periodic (occurs periodically) interval (task duration)
