Web Evolution 5280 ft View of the Web 2. 0 Christopher Fowler Software Developer of e. Government and Information Technology Secretary of State of Rhode Island

Why “Evolution” l There is no grand plan to the web l Competing technologies – Non-survival of the least fit – There is a natural progression of how we got here l Not entirely possible to predict the future, but we can make guesses due to trends

Where Are We Now? l Some Call it Web 2. 0 – Not to be confused with Internet 2 l No Clear demarcation – HTTP protocol appear out of the Internet sea – HTML Static Web Pages (Brochure. Ware) take off – Dynamic data becomes integrated into web pages – Web pages become interactive (Java. Script, cookies) – Web Applications appear

So Where Are We? l Still no clear demarcation – XML - Markup starts to define Data, not just data placement and presentation – HTML is “cleansed” – XHTML is beautified – CSS – XML starts to define protocols l Birth of RSS – Web Services drive web content delivery

Web Services: This Is Where We Are l The reliance on Web Services is the Web 2. 0 l This is not a promise – it’s the implementation of yesterday’s promise

The Reality of Web Services: l Human readable computer friendly protocols – Open Data l RSS – Single point of creation – Multiple sites provide same data – not recreating it – Open Services l l l Amazon API Google API RSSonate (developed by yours truly!) del. icio. us Flickr
