1.

UKOLN also receives support from the University of Bath where it is based.

2. About WWW9 • WWW9 conference: • Held in Amsterdam on 16-18th May • Tutorials and Workshops on 15th May • Developer's Day on 19th May • The conference: • Attracted about 1,400 delegates • About 100 from UK (~50% from HE) This year only 2 papers from UK HE: Alison Cawsey, Heriot-Watt and ???

3. Conference Highlights • WWW9 was the key of the Mobile Web: • Keynotes from Psion and Ericsson • "Towards A WAP-Wide Web?" Forum • Another keynote from Philips (Digital TV) • Also more technical discussions and criticisms: • "Why have a WAP-Wide Web when we have a World Wide Web?" • "The WAP Forum is too proprietary" • "We haven't got the resources to author for the Web and the mobile phone"

4. Will The Mobile Web Take Off? <www.tomtom.com> • Some comments: • It has done in Japan (more mobile than PC Internet users: >10m according to ITWeek) • Lot of investment • Some interesting prototypes (e.g. <www.tomtom.com>) • What should UK HE do? • Can't ignore it • Need to thing about use of content management systems and structured file formats to author content for the Web, mobile phones, print, etc.

6. W3C Developments - XHTML • XHTML Tutorial session: • Ran by Dave Raggett, Murray Altheim & Frank Boumphrey • "There will be no HTML 5.0. It would be too large and cumbersome (only MS could implement)" • Need for HTML to be an XML application • Need for HTML to be modular: • Add new modules (extended forms) • Remove modules (e.g. for embedded devices) • XHTML: • Satisfies these requirements • Is available now (XHTML 1.0 is a W3C Rec.) • Should be used now (with CSS)

7. XHTML (cont.) • Converting from HTML to XHTML: • Can be done by Tidy • Can use editors such as HTML-Kit, which embed Tidy • Finding Out More • XHTML-L Mailing list <http://www.egroups.com/group/XHTML-L> • "Beginning XHTML" book • HTML Writer's Guild <http://www.hwg.org/> • W3C Web Site <http://www.w3c.org/> • XHTML Spec <http://www.w3.org/TR/xhtml1/>

8. XSLT • XSLT: • Extensible Stylesheet Language Transformation • A Language for transforming XML documents • Can transform: • XHTML  WML • RDF  text • Etc. XHTML+XSLT =  <xsl:template match="employee"> <fo:block> Employee <xsl:apply-templatesselect="name"/> belongs to group <xsl:apply-templates select="ancestor: department/group"/> </fo:block> </xsl:template> Paper at WWW9 conf by Alison Cawsey, Heriot-Watton "Presenting tailored resource descriptions: Will XSLT do the job?"

9. Poster Proceedings • I had two posters accepted and included in the Conference Poster Proceedings: • Approach to Indexing In The UK • A Lightweight Approach To Support Of Resource Discovery Standards • Papers and posters available at <http://www.ukoln.ac.uk/web-focus/papers/www9/>

10. Approach to Indexing In The UK • Summary: • Survey of search facilities on UK HE Web sites carried out (see Ariadne) • ht://Dig most popular – about 50 with none • But users want to find resources, not just resources on the Web site • eLib phase 3 aims to allow users to search: • OPACS on regional / subject basis (e.g CAIRNS) • Web sites, gateways and OPACs (e.g. Agora) • DNER aims to provide integrated access to JISC (and local) resource

11. A Lightweight Approach To Support Of Resource Discovery Standards • Summary: • Dublin Core is known to be a good thingTM • But: • Authoring tools aren't available • Tools and services to exploit DC aren't available • What if the format changes (e.g <META> to RDF)? • Exploit Interactive • EU-funded Web magazine produced by UKOLN • Available at <http://www.exploit-lib.org/> • Provides information on Telematics for Libraries projects and other topics of interest to library community • Also acts as test-bed for UKOLN's research interests

12. A Lightweight Approach To Support Of Resource Discovery Standards • Solution: • DC stored in neutral format • Transformed into <META> tags • Used by MS SiteServer

13. Exhibition • Two interesting exhibitors: • Nedstat: Externally-hosted statistical service, based in Holland • AltaVista:Indexing Tool: • 80% discount for HE (+ T shirt) • Can be used to index remote sites (price per resource indexed) Search service: • Want to index everything that's not spam • Different indexing policy for altavista.co.uk (indexes deeper)

14. Developers Day (AM) • Semantic Web Track "Using Z39.50 and RDF to Support the UK Mirror Service" – Dave Beckett RDF used in a large-scale service environment (200 mirrors, 440 Gb, 2-3 M files). Little mention of Z39.50 "Collaborative Web Authoring" – Jose Kahan, W3C Amaya used to store annotations on annotation server. Other users linked to same annotation server can see annotations. DOM used to update document with icons once HTML page rendered.

15. Developers Day (PM) • Web Publishing Tools and Techniques • "InfoSite Content Manager" A web-based content management system <www.infosite.com> • "WebLogs in Manila – Tools for Writers", Dave Winer Manila is a web-based content management system <manila.userland.com> It is targeted at the mass market ($799 per server) Can be used to created "weblogs" – see <www.weblogs.com> and <http://www.userland.com/> It appears to be very standards-based

16. Developers Day (PM) • XML Publishing Applications • "XML At the Koninklijke Bibliotheek", Simon Bosse KB (National Library of the Netherlands) are taking a centralised approach to providing access to KB resources. This contrasts with the UK's distributed approach taken nationally using Z39.50 The difference is due to KB's concerns over the costs and difficulties of deploying Z39.50, although a distributed approach is recognised as better Slides at <www.kb.nl/persons/simon/kbc-en/>

17. Developers Day (PM) • XML Publishing Applications • "Using XML for News Aggregation and Delivery", Dave Galbraith Described how the Moreover Newsfeeds service makes use of XML, RDF and RSS Comment UK Universities, JISC services, etc. should have an interest in newsfeeds (both receiving commercial feeds and providing feeds internally and externally). See <www.moreover.com>

18. RSS • Much discussion about RSS (Rich Site Summary): • XML application initially developed by Netscape for their personalised My.Netscape service • Very popular • But: • Ownership unclear (AOL/Netscape quagmire) • Is being extended • Standardisation process unclear ("W3C would insist on RDF!") • See: • http://www.perl.com/pub/2000/01/rss.html?wwwrrr_20000126.txt • http://my.netscape.com/publish/help/mnn20/quickstart.html • http://www.ukoln.ac.uk/metadata/resources/rss/

19. Lunch With Tim Berners-Lee • Tim Berners-Lee acting as lunchtime TV chat show host: • The Web is broken / The Web is developing nicely – discuss. • "Is the Web like Visicalc / Apple? Version 1 was great, but the founder failed to deliver with version 2? The Semantic Web = Apple III

20. WWW 10, 11 and 12 • WWW 10 Hong Kong, 2001 • WWW 11 Hawaii, 2002 • WWW 12 To be decided. Possibly the UK (Birmingham) or Hungary
