MultiReader

1. MultiReader <?MultiReader_Topic Map Prototype?> Topic Map & SMIL Prototypes KUL-ESAT-DOCARCH <?Research Group on Document Architectures?>

2. First Topic Map prototypes • Topic Map creation • Using XTM syntax - XML Topic Map DTD 1.0 • Topic Map design • Definition of Topic Types • Definition of Occurrence Types for each Topic • Definition of Association Types between topics • Topic Map editing • Creation of Real topics of a certain Topic Type • Creation of occurrences and associations between topics and occurrences • Creation of associations of a certain type between real topics <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

3. Topic Map Prototypes • Topic Map environment • Topic Map processing: 2 approaches • ‘XSLT’ approach • ‘Specific Topic Map software’ approach • Ontopia Toolkit (Java) • www.ontopia.net • Application environment - quick start • both web applications • Java servlet technology <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

4. Topic Map Prototypes • XSLT approach • Conversion Topic Map  HTML environment • List of all topics • List of all topic types • Conversion Topic Map  SVG environment • Topic Map search demo  General Topic Map showcase (technical view), software can be used for other Topic Maps <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

5. Topic Map Prototypes • Specific TM-software approach • Ontopia toolkit • Java implementation • In-memory storage of Topic Map constructs  More specific built for our recipe prototype <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

6. Topic Map prototypes • Xslt advantages • XML W3C standard  XML advantages • Software independent • Platform independent, flexible … • Flexible to change output (html listview, html detailview, svg view, etc.) • Xslt disadvantages • Not flexible for Topic Map processing • hard to select topics from the map etc. <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

7. Topic Map prototypes • Ontopia advantages • Better suited for navigating / processing a Topic Map • Ontopia disadvantages • Software vendor dependent • Mixture of software and publication part • Not so easy to change output (html listview, html detailview, svg view) <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

8. Future Plans - Proposal for the next Topic Map prototype • Combining the advantages of the first prototypes • Combination of the Ontopia approach and the XSLT approach • A Topic Map preprocessor (Ontopia or DOM application) in combination with a formatter (XSLT) <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

9. …next Topic Map prototype • Task preprocessor • Preprocessing of the global Topic Map • Generating a ‘mini’ Topic Map with all relevant information cfr. the user request. • Result set = all information of 1 of more topics in XTM syntax. • Application independent • Can be used for cookbook prototype, reused for tourist guide etc. • Ontopia application or DOM application or database storage of TM = research item <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

10. …next Topic Map prototype • Task XSLT engine • The publication part • Publication of the ‘mini’ topic map = result of the preprocessor • Flexible Publication: html listview of topics, html detail view, svg view etc. • Interacts with the user interface (gets parameter info of UI) • for scope handling (f.e. language) • selected view (listview, detailview, svg etc.) • Application dependent like the TM & UI <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

11. TM & SMIL - ideas • Topic occurrences (occurrence results after TM preprocessing and XSLT formatting of mini TM) in a (double) SMIL wrapper Example: The topic ‘Paris’ • 2 occurrences: a text fragment of Paris and a picture of Paris • 3 ‘alternative media‘ occurrences: a speech version of the text fragment, a text version of the picture and a speech version of the text variant of the picture Goal: each user in the MultiReader environment needs a different combination of occurrences = a personalized multimedia presentation <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

12. TM & SMIL - ideas • Possible solution: • ‘Base’ occurrence with ‘alternatives’ in a SMIL wrapper. • Resulting in 4 occurrences in our example: the 2 base occurrences and 2 SMIL occurrences, one for each base occurrence. • ‘user (media) profile’ on SMIL level (f.e. I want text and sound for each occurrence, no video, no pictures) = item for research  Transforming the Topic Map world to a MultiReader world = providing for each topic occurrence a SMIL variant which provides alternative media for that occurrence = SMIL fragments <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

13. TM & SMIL - ideas • Next step: combining the SMIL fragments in a personalized Multimedia presentation • Extra SMIL wrapper / info for the position and synchronization of the different SMIL occurrences / fragments = 2 layers of SMIL??? • Also need for a wrapper in the normal topic map occurrence world for presenting the occurrences • F.E. a SMIL wrapper which provides one occurrence after the other (sequence of <seq> elements) • SMIL wrapper or HTML template or …. ???? • Seocnd wrapper could be dynamically built based on UI settings (interaction with the user) <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>

14. TM & SMIL - ideas • Synchronization problem • How synchronize pieces of multimedia fragments? • F.E.: synchronizing each step of the preparation of a meal (all steps in one textual occurrence) with the corresponding pieces within the video occurrence? • Video fragment and text both part of the ‘SMIL’ occurrence of occurrence type preparation. • Same for text-speech • SMIL ??? <?MultiReader_Topic Map Prototype?> <?Research Group on Document Architectures?>
