1. Web Tools A Technical Perspective Tim Bornholtz

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

3. RSS – Versions Owner Pros Status Recommendation Version RSS 0.91
UserLand
Very simple
Officially obsolete by 2.0 but still widely used
Use for basic syndication
RSS 1.0
RSS-DEV Working Group
RDF based
Stable core
Use for RDF-based applications
RSS 2.0
Easy migration from 0.9x, widely accepted
Stable core, active module development
Use for general purpose metadata rich syndication
Atom 1.0
IETF
(RFC 4287)
Open standard, widely accepted
Official IETF standard
Use whenever possible

4. RSS 2.0 vs Atom
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

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

6. How to implement 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" />

7. Developer Tools 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

8. Web sites as web services
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

11. Hotjobs RSS feed

13. Google code sample

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

15. Mobile Web Browsers Many Ajax calls will not work on a mobile phone
<link href="/css/screen.css" media="screen" rel="Stylesheet" type="text/css" />
<link href="/css/hh.css" media="handheld" rel="Stylesheet" type="text/css" />
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

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

17. "Jesus reflected on his situation and felt irrepressible sadness
"Jesus reflected on his situation and felt irrepressible sadness. His tear-ducts filled to a point where they could hold no longer and had to be released."

18. "Jesus reflected on his situation and felt irrepressible sadness
"Jesus reflected on his situation and felt irrepressible sadness. His tear-ducts filled to a point where they could hold no longer and had to be released." Vs
“Jesus wept.”

Pure object oriented
Interpreted scripting language
Loosely typed language

Full stack framework
Model-View-Controller pattern
Ajax built in

21. Ruby on Rails Benefits 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

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