Web 2.0 Development Ideals
Extremely Frequent Releases: Bugs go away faster,
smooth evolution
Small Pieces, Loosely Joined: Makes change easier, less
risky but the parts are also less specialized and hackable
Lightweight Programming Models: Languages and
Summer <Web /> 2.007
simple data formats make development easy and cost-
effective
Users as Co-Creators: Offering them the features they
want, allowing them to contribute information and attention
Real-time Feedback and Sampling: watch what they do
and use the feedback to create an better product

So what’s a mashup?
“A mashup is a website or application that
combines content from more than one source into
an integrated experience
Content used in mashups is typically sourced from a
third party via a public interface or API
Summer <Web /> 2.007
Other methods of sourcing content for mashups
include Web feeds (e.g. RSS or Atom) and
JavaScript”

So what’s a mashup?
That encourage software creators to expose
their applications as sets of reusable services
and encourage others use the good pieces of
what they provide in new and innovative ways,
easily wiring together the little pieces
Summer <Web /> 2.007
On the demand-side there is a rising comfort
with and expectation of finding a throw-away
application to do just the one thing you
needed when you need it

The advantage of in-browser client mashups is
the complete portability and mobility they offer
The advantage of server-side mashup is that it
simplifies the client and offers a programming
infrastructure that is much deeper and more
powerful

Limitations & Challenges
Limitations of APIs
Query size / Quantity – less than 50,000 hits per day
(Google Maps)
API change? Can you keep up?

Cross-domain security problem
Legal Issues: quot;It's simply combining two things but not
(adding) a lot of intellectual property on top of it. The
problem is the people giving you the content want to be
compensated. You are in fact a reseller of that content.“
