The Ubiquitous Web - what is it?

• Synthesis between the World Wide Web and Ubiquitous Computing
• Making it much easier to build distributed applications across a diversity of networked devices
• Context awareness - dynamically adapting to users, devices and environmental conditions
  • Exploiting the features of each device, and not dropping to the lowest common denominator
  • Giving users the means to select the modes of interaction that best meet their needs, subject to the capabilities of the devices
  • Extending device capabilities through access to network services and through combination with other devices
  • Providing remote user interfaces to devices and services

The Ubiquitous Web - what is it?

• Application mobility - enabling users to seamlessly switch between devices whilst continuing with the same application
  • seamless in the sense of not requiring significant conscious effort from users
• A greater focus on the network rather than on particular devices, and an associated need to address trust, security, privacy and identity
  • Your data lives in the network, but applications need to allow for temporary lapses in connectivity
  • Combining local information with network-based information sources

Workshop Goals

The main objective of this workshop is to help W3C to build a better understanding of the Ubiquitous Web, and to identify potential areas for standardization:

• To explore the vision of the Web as a distributed applications platform that works across a wide range of devices in areas such as offices, home networks, mobile, automotive, aviation, etc. with the potential for increasing the range and reducing the cost of developing and deploying such applications.
• To explain how current W3C work fits into this vision, e.g. work on Web Application API's, Delivery Context Interfaces, Device Descriptions, Multimodal Architecture, etc.
• To identify and prioritize additional areas which would benefit from standardization, in particular, the integration of sessions and device coordination into web applications.

See Call for Participation and Workshop Agenda

1st Discussion Period

Break out sessions (3 or 4 groups) with access to white boards

• 1130 - 1200 Use Cases for the Ubiquitous Web
  • Describe a few use cases and the role that Web technologies plays in them
• 1200 - 1230 Security, Privacy and Identity
  • Drawing upon the use cases, discuss what requirements there are for sharing information, and for controlling access to devices and services. How could these requirements be met?

We all get back together

• 1230 - 1300 Breakout reports and discussion

Each group will need to appoint a volunteer to report the group's findings to the workshop. You are free to do this as you see fit, but there needs to be a record that we can include in the workshop's minutes. One idea would be to use PowerPoint or Open Office to create lists of bullet points, but plain text and HTML would be fine too.

2nd Discussion Period

Break out sessions (3 or 4 groups) with access to white boards. Groups can select their own topics if they think it appropriate.

• 1545 - 1615 Printing and the Ubiquitous Web
  • Uses cases involving printing including PC-less printer operation. Device/service descriptions for printers. What has been done, and what remains to be done?
• 1615 - 1645 Device Coordination
  • This covers the means for discovering and binding resources within temporary or persistent sessions. What is needed for scalable discovery? What value can be added above existing frameworks such as UPnP? What does it mean to expose device coordination to markup languages and web page scripts?

We all get back together

• 1645 - 1730 Breakout reports and discussion

3rd Discussion Period

Break out sessions (3 or 4 groups) with access to white boards. Groups can select their own topics if they think it appropriate.

• 1130 - 1200 Context Awareness/Adaptation
  • Context can include user preferences/needs, device capabilities and environmental conditions. At a more detailed level, what kinds of context need to be modelled and how does this support adaptation? Where does that adaptation occur? What role is there for higher level languages for modelling applications?
• 1200 - 1230 Metadata and the Semantic Web
  • UPnP uses a relatively weak approach to describing devices and services. The ability to combine remote sources of information offers the potential for richer notions of discovery and adaptation. What is the role of the Semantic Web and is there a place for approaches based upon the collective behavior of many people.

We all get back together

• 1230 - 1300 Breakout reports and discussion
