RSS:
• Killer lightweight format
• Initially used to allow news to be
embedded in others Web sites
• Now used for general syndication of
content
• Use in Blogs helped in take-up
• Lots of ways of using RSS, creating RSS,
RSS tools, etc.

RSS & OPML As A
Navigational Aid
OPML provides an
import/export
function for groups
of RSS files
Can also be used
for navigation
Mashups – take the information to the
people, don’t force them to come to you
A centre of expertise in digital information management

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

Searching RSS Space

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

Creating The RSS
http://www.wotzwot.com/
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).

Location Services
Mapping Services & The Web
Web 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

Google Map ‘mashup’
used for IWMW 2006
event:
• ~ 20 lines of
JavaScript.
• Code taken from
Google Maps Web
site and
coordinates added
More sophisticated
mapping applications
are being developed,
such as Radius 5 at
Northumbria
Univ.

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

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 www.ukoln.ac.uk
tools
What Next?
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
&inour
users)
gain
as more of us do this.
