• Killer lightweight format• Initially used to allow news to be

RSS RSS As A Navigational Aid
RSS feeds for structure of Cultivate Interactive created recently
RSS file for home page (and similar) provides links to each issue
RSS file for an issue provides table of contents for issue

RSS files created in Aug 2006, usingRSSxl (see later)

RSS
RSS & OPML As A Navigational Aid
OPML provides an import/export function for groups of RSS filesCan also be used for navigation
But I can provide such navigation using my CMS?Yes, but remember that the interface can be embedded on 3rd party Web sites – which your CMS doesn’t manage
Mashups – take the information to thepeople, don’t force them to come to you

RSS Searching RSS Space
Technorati provides a searching service for Blog space/RSS space

Thoughts – if you want to be visible in Technorati, you’ll need to create RSS – or encourage others to Blog about you

RSS Creating The RSS
Lot’s of ways, but a simple technique for existing resources is to make use of an HTML-RSS converter.Can process:
• ‘Microformats’ e.g. <span class= “rss:item”>
• Arbitrary text such as <li>No need for a complex CMS!
Some trivial edits allowed the feeds to be tidied up. File saved as static file with persistent URI. Approach v. useful for legacy data (old projects). Not will be even better in IE 7 / FF 2 world.

Mapping Services & The WebWeb 2.0 provides valuable opportunity to provide mapping & location services:
• Embedding Google maps on your Web sites
• Developing rich services using this• Providing location metadata /
microformats which can be processed by simple browser tools

ices Google Maps MashupsGoogle Map ‘mashup’ used for IWMW 2006 event:
• ~ 20 lines of JavaScript.
• Code taken from Google Maps Web site and coordinates added
http://www.ukoln.ac.uk/web-focus/events/workshops/webmaster-2006/maps/http://northumbria.ac.uk/browse/radius5/
More sophisticated mapping applications are being developed, such as Radius 5 at Northumbria Univ.

ices Location Metadata (1)Embedded location metadata can now by exploited by various 3rd party tools
How? Install Greasemap script & add:<meta name="geo.position" content="55.944…, -3.187…" /> <meta name="geo.placename" content="Edinburgh University" />
http://www.ukoln.ac.uk/web-focus/events/meetings/edinburgh-2006-09/
Note I shouldn’t do this, the organisation should be responsible for its own metadata (I’ve probably got the wrong building!)

ices Location Metadata (2)
Same location metadata can be used by other applications.

Note also Geo microformats – embed location inline in HTML text, which can be exploited by various tools

Challenges & Opportunities Challenges:
• Accessibility (can be addressed)• Resourcing• Reliability, robustness, quality, trust, etc.• Will users use it? Do they want it?
Opportunities:• Significant benefits at low cost• Being (slightly) at the leading edge• Discussing & sharing best practices, coordination• Software development (EDINA, UK, … scripts, etc)• …
Key points: Much of this stuff can be easy to do, so let’s do it! Remember the benefits of scale (Metcalfe’s Law) that we (developers & our users) gain as more of us do this.
