The enemy keeps changing. Bloated 'enterprise'

us. First DCE, then CORBA, next J2EE and now:

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...

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 (GetSearchResults, GetItem,
GetCategoryListings, etc).
In this dialogue series,
I argue the case for eBay to adopt a truly REST approach to
their integration API.

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 |

It gives me great pleasure to announce the 2006 'What Now How'
Awards for REST Protocols (or 'APIs') in the Read/Write
Category.
All this year's awardees share the distinction of being truly
worthy of the 'REST' label; these Read/Write Protocols are
acknowledged here for their uncompromising adherence to the
simple principles of the World Wide Web.

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!

The vast majority of supposedly 'REST' Web APIs are simply
abusing HTTP to carry function calls. I call
these APIs 'Service-Trampled REST', or STREST.
STREST APIs come with specific costs which could stifle
the two-way data Web (Web2.0) if allowed to propagate
unchecked. Although 'mashability' is a supposed benefit of the
current proliferation of APIs, true interoperability and
scalability can only be guaranteed by true REST interaction.
This is not an academic, purist or aesthetic stance, but one
based on practical consequences, as I will explain.
