  2. XML file published to a web site Aggregators periodically retrieve your file (This is slightly different than I said in the business session) RSS

  3. RSS – Versions

  4. RSS 2.0 Plaintext or escaped HTML (no way to signify which) RFC 822 date format US ASCII only More widely adopted Atom Explicitly set content type (plain text, escaped HTML, XHTML, XML, and binary) RFC 3339 date format (XML standard) Supports Unicode Not as widely adopted but more flexible RSS 2.0 vs Atom

  5. <?xml version="1.0"?> <rss version="2.0"> <channel> <title>Sample Feed</title> <link>http://example.com/</link> <description>Current news entries</description> <language>en-us</language> <pubDate>Tue, 27 Apr 2008 04:00:00 GMT</pubDate> <item> <title>Article Title</title> <link>http://example.com/2008/04/27/sample.html</link> <description>As much of the article as you wish to display here</description> <pubDate>Tue, 26 Apr 2008 09:39:21 GMT</pubDate> <guid>http://example.com/2008/04/27/sample.html#item573</guid> </item> </channel> </rss>

  6. Determine the content Generate the XML feed Assign a well recognized URL Post the RSS feed on your website Use common images for linking Modify existing HTML to include link to feed<link rel="alternate" type="application/atom+xml" title=“Atom Feed" href=“feed/atom" /> <link rel="alternate" type="application/rss+xml" title="RSS Feed" href=“/feed/rss" /> How to implement

  7. Source Code Tools publish RSS Project Management Tools Calendar RSS with every milestone RSS with all recent activities Bug tracking tools RSS for my outstanding bugs Developer Tools

  8. Website APIs – Usually REST based but many are SOAP based Unstructured information gives way to structured information Google, Yahoo!, MSN Live, Amazon, YouTube, and many more Web sites as web services

  11. Using the APIs of two or more sites to create a new site Yahoo! Pipes http://programmableweb.com At this point it is more of a curiosity and a collection of interesting ideas than a business driver. Mashups

  12. <link href="/css/screen.css" media="screen" rel="Stylesheet" type="text/css" /> <link href="/css/hh.css" media="handheld" rel="Stylesheet" type="text/css" /> Mobile Web Browsers • Many Ajax calls will not work on a mobile phone • Section 508 compliant web sites require very little changes to work on a mobile phone

  13. Many recent improvements in web frameworks Ruby on Rails, PHP, Python Designed specifically for developing web sites Quick development speed Long term maintainability Considering dynamic languages

  17. Ruby is the programming language Pure object oriented Interpreted scripting language Loosely typed language Rails is the web framework Full stack framework Model-View-Controller pattern Ajax built in Ruby on Rails

  18. Vastly reduced code footprint Zero configuration DRY – Don’t Repeat Yourself Rapid development methodology Ajax UI support IDE automation not required Open source Integrated testing Ruby on Rails Benefits

  19. Relatively new framework Difficult to retrofit to existing database schemas The Rails way or the wrong way – no middle ground Ruby on Rails Cautions
