The Web:
Long Tail & Fragments
 The Web is a scale-free, fragmented network
– The power law (Pareto-Distribution etc.)
– 95 % of users are located in the Long Tail (Communities)
– Trust and passion based cooperation

Communities of Practice
 Communities of practice (CoP) are groups of people
who share a concern or a passion for something they
do and who interact regularly to learn how to do it
better (Wenger, 1998)
 Characterization of Professional Communities
– Shared competence in the domain
– Shared practice over time by interactions
– Expertise based on gaining and having reputation within the CoP
– Being an expert vs. being a layman, a newcomer, an amateur etc.
– Informal leadership
– Identity as an expert depends on the lifecycle of the communities
Supporting highly dynamic, locally distributed, multi-disciplinary
and heterogeneous communities?

The Next Web will
be no Internet of Things …
… but a huge collaboration platform for professional
communities with (some) of the following features
– P2P Browsers as new Web OS in the Cloud
– Mobile & Social (Location-Based Community Services)
– Near Real-Time (WebRTC, XMPP)
– Multi-Device Operations
In the following we will address some of the
Web Engineering Challenges

Semantic Video Annotation
(SeViAnno)
 Aims at capturing and sharing meaning
– In communities of practice
– For personal use
 Example
– Markup of text for learning (different colors, etc.)
 Different kinds of semantic annotations
– Descriptive (search & locate, e.g. keywords, description)
– Technical/administrative (internal info, e.g. creation, type)
– Structural (storage & presentation, e.g. video segments)

DireWolf Framework:
Distributed User Interfaces (DUI)
 Challenge for a web application with only one device
 Goal: distribute widgets over multiple devices of the single user
when requires full screen video,
other widgets become unreachable
expand the application to multiple devices
Map on iPhone
Other widgets on PC
Video player on iPad
