2. eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology Chronicles An extended account in prose or verse of historical events, sometimes including legendary material, presented in chronological order and without authorial interpretation or comment. A detailed narrative record or report. Uses multiple media streams to record proceedings Edited or logged Is recorded and presented using electronic recording and presentation mechanisms. No legacy of paper/print media Multimedia Electronic Chronicles (eChronicles)

4. eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology Semantically-related information is fragmented across media and directories A rigid logical and/or physical hierarchy is used for categorizing the information Spatial and temporal information, essential to events in the physical world, are not considered necessary and are therefore, unavailable Patterns in the data that may answer the “how?” and the “why?” are lost Challenges

5. eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology Event based approach Data is related to events ( e.g. in our life) An “Event” is an occurrence or happening of significance that can be defined as a region or collection of regions in spatial-temporal-attribute space Most data and information is related to events. Temporal and Spatial organization is a fundamental mechanism used by people. People organize information and data around events and entities. Entities are a special case of events. Why Events?

11. eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology Conclusions ‘Events’ are useful in unifying context and multifarious data. Why and How are naturally answered if an application is modeled using events. Event-based indexing and organization of data provides both information and experience. eChronicles have many diverse applications.
