From HTML To Services

Hypertext and Pictures grew the Web

Thank You!

Let’s Move On…

Hypertext

Very 90’s

Your content links their content

Click, Good-Bye

… But!

HTML is parseable markup

Structure focused on layout but holds data

corzen.com spiders hundreds of jobsites weekly and aggregates that into a leading indicator for Wall Streets job market data

XML is generalized parseable markup

Structure focused on data

Facilitates “Community Standards”

RSS, OPML, etc

Sites are services today

Mashup

Mashup Consumers

Your content is your content and their content and the other’s content… and they let you!

Keep people on your property

Rake the ad revenue, drive business for partners

Mashup Providers

Their content is your content

Make it easy to aggregate your stuff

RSS, OPML, ATOM, ASX, any other XML Lingo

JSON – JavaScript Object Notation

Make it easy to interact with your stuff

REST, POX, and SOAP Services

Rake in the revenue for your added-value or services

It’s A MIX

HTML+AJAX: Client Aggregation Platform

We love Firefox, Safari, Opera for embracing our XMLHTTP model … and for finally kicking NS 4.x off the cliff

Critical mass for cross-browser XML and AJAX support is here

Aggregate, embed, layer, extend, reshape, recompose, map, render… do stuff

It’s A MIX

Go cool with Avalon/WPF and Flash

Go mobile with J2ME and Windows Mobile

Go living-room with Windows Media Center and Xbox 360

The web of now is one of services and many presentation surfaces and facets

HTML isn’t dead, but it’s got company

X’ing The Wire HTML/HTTP

HTML/HTTP are the common fabric

The Web’s Denim Jeans

Comfy, essential basics, but not so chic

Provides the most fundamental layout and content integration capabilities

HTTP is the ubiquitous, scalable communication underpinning with a huge supporting infrastructure.

Great for 90% of everything. But just that

X’ing The Wire REST/POX

POX: Plain Old XML

Ship XML instead of HTML

HTTP GET to access XML data

Easily aggregate and mashup with AJAX

REST: REpresentational State Transfer

Aka “POX with dogma”

Fully exploits HTTP application protocol

Create/update/delete and linking

Very casual, baseline standards, do what works…

X’ing The Wire SOAP

SOAP: Data + Metadata for Messaging

Baseline standard for rich set of messaging features

Addressing, Routing

In-Message Security, Identity Federation

Reliable Messaging

Very rich model, requires rich stacks

SOAP is no longer a toddler... or easy

X’ing The Wire Streams/P2P

Streamed Media, Large Data access

Downloads

Music On-Demand

Video On-Demand

P2P: Collaboration, Sharing, Gaming

Eastside, Westside, Serverside Pinstripes or Hip-Hop, nothing happens without the server

Windows Communication Foundation The Windows Communication Foundation is the Universal Communication Runtime SOAP, REST, POX, P2P, Streaming. One-Way, Request/Response, Duplex. Secure, Transacted, Reliable, Federated. Interoperable, Productive, Fast One Way to Program

POX, No SOAP

What Did We See?
