11. Patterns
Repeatable solution to a commonly occurring
problem.
Patterns can be repurposed across multiple
domains and used to solve recurring problems
there within.
Example: Collaborative Tagging (aka Folksonomy).
Can be used for audio files, video files, text files, binaries, people…

12. Common Web 2.0 Patterns
Collaborative Tagging (folksonomy) Participation/Collaboration
Synchronized Web (harnessing collective intelligence)
SOA Adaptive Software
SaaS, DaaS (variations of SOA) Microformats (a.k.a. fine grained
content accessibility)
Persistent Rights Management
Declarative Living / Tag Gardening
Mashup
Incremental Update (a.k.a. “Atomic
Rich User Experience (a.k.a. RIA, Particle Update”)
knowing something about your
users) … (more)

13. Models
The model for engaging using the
internet as a platform to span all

14. Models
Definition: Abstract lexicon capturing a generalized set of
concepts and noting their purposes and relationships to
each other.
Primary Audience: Entrepreneurs, Software or Enterprise
Architects
Why:
Models guide all domains, whether explicit or implicit. They facilitate a

18. Reference Architecture
A technology component view of a generalized architecture.
NB!: Abstract of all technologies (HTTP, TCP/IP java etc)
and abstract of all applications or vendor products.
Agnostic to patterns of usage.
Primary Audience: Software or enterprise Architects,
developers
Why: There is a great value in being able to communicate
ideas and functionality abstract of specific technologies
protocols or products. These become artifacts that can be
applied by architects in multiple domains.

20. Service Oriented Computing
Re-purposing core functionality as service to be consumed.
But wait! What about the clients?
Do they have to be different?
Service Oriented Clients (SOC’s)?
Service Oriented Clients are, in most cases, Web 2.0
applications!

21. Service Oriented Clients - Web 2.0 Application Architecture
Mashing up multiple formats
Using services to deliver rich user experiences
Rendering/Media engines let users control the way they use your
applications.
Are no longer standalone - use knowledge of other users applications.
