Say we want to integrate multiple applications which handle order processing. OK, that's
got to be one of the dullest starts to a blog post. Never mind, bear with me...
So, we have applications on separate servers for handling and driving data such as
orders, product descriptions and catalogues, stock lists, price lists, tracking, packing
notes and delivery notes, invoices, payments, etc.
We may choose an SOA approach, of course. But let's say our sponsors have heard of this
cheaper alternative: REST! Which to them means 'using Web technology to save money'.
Now .. suppose we push the time slider right back to before Mark Baker and the SOA -vs-
REST Wars - or the 'SOAP -vs- REST Wars' as people naively called it. To when REST was
simply (!) a description of the Web's architectural style...
What if we revisit the applicability of the Web, and its abstraction into REST, to the
architecture of machine-to-machine distributed systems - to something like our order
processing integration?
I think we'd quickly arrive at something that looks more like
FOREST
than, say, AtomPub...

In an exclusive nine-part dialogue with an imaginary eBay
Architect, we present an accessible discussion of the
REST vs. SOA issue.
Although eBay have what they call a 'REST' interface, it is, in
fact, a
STREST
interface, and only works for a few of the many function calls
that they make available via SOAP.
In this dialogue series,
I argue the case for eBay to adopt a truly REST approach to
their integration API.

Last night's
Google London Open Source Jam
(also here)
was on the subject of the 'Web' (didn't they invent that? Oh no,
that was Microsoft).
This event has been getting better and better each time I've
attended. There were some very interesting lightning talks held
together with a tight structure and plenty of chance to chat,
drink cold Leffe and eat cold pizza. And nick [transatlantic
translation: 'steal'] the
Green & Black's chocolate.
An ideal Micro Conference...

Web 2.0's definition
includes seeing the Web as an application platform. Which means it
is in competition with Java and .Net, and with SOA, for both local
and widely distributed applications.
If the Web is going to be a platform, the skills you need to learn
to program it are the core Web 2.0 technologies such as Ajax, JSON,
Atom, Microformats and OpenID.
And Ruby. This language, that's capturing the hearts of many Web 2.0
programmers, is ideal for easing the transition from the Java
and .Net platforms to the Web platform, as I will show.
Even if you're part of a big company that is generally immune to the
latest trends, the marriage of Ruby and the Web-as-platform may be
something to prepare for. It could even displace your SOA agenda...

What do all the MAJOR Web 2.0 technologies of 2007 have in
common?
Let me list them first:
M.icroformats (including tags)
A.jax (including Comet)
J.SON (plus YAML)
O.penID (plus SXIP, LID, Yadis)
R.EST (including Atom, APP)
What these technologies have in common is that they're
all lighter than their competitors:
Microformats | Lighter than the Semantic Web |
Ajax | Lighter than Fat Client (!) |
JSON | Lighter than XML |
OpenID | Lighter than SAML/Liberty Alliance |
REST | Lighter than SOA |

Don't write your interactive Web application in custom
Javascript! The Web's Declarative nature needn't be
broken just because you want two-way dynamic data instead of
one-way documents on your site.
Instead, write Declaratively to generic Javascripts, plugins
and browser features such as
Hijax,
hInclude,
XForms,
SVG, XBL, etc.

Microformats are subversive:
they not only challenge the approach of full-blown Semantic Web
approaches, but even question fundamental Web 2.0 building
blocks such as Web Feeds and Web APIs.
I recently attended
XTech 2006,
where there were a few talks related to Microformats.
After summarising these talks, I'll finish with my shocking
revelations about the subversive nature of Microformats!
