NOF-digi & JISC Standards documents: • Use PNG; SVG; SMIL; … • Flash, PDF, Java, … aren’t open so they don’t fit in with an open standards approach • Web Services & Semantic Web standards will be important What happened: • PNG; SVG; SMIL? • Flash; PDF; Java – widely deployed, so a more flexible approach for use of standards was adopted • Web Services Considered Harmful panel at WWW 2005 • Amazon report REST approach preferred to W-S* standards (80/20) • Semantic Web vs. l/c semantic web debates flourish; • W3C revive HTML developments 3 An “evidence-based” approach begins to be preferred A centre of expertise in digital information management www.ukoln.ac.uk to ideological beliefs Role of Web 2.0 Web 2.0: • Forget (for now) blogs, wikis, etc. • Consider characteristics such as rapid development, user engagement, ‘always beta’, clean URIs, microformats, mashups, … Suggestion: • Web 2.0 clearly provides (today) the rich environment for developing popular & userfocussed services • We should be looking (outwards) at the successes of the Web 2.0 environment and not (inwards) at new schema developments A centre of expertise in digital information management 4 www.ukoln.ac.uk Light- vs. Heavy-Weight Development Lightweight Exploitation: • Companies with limited funding (6 months to release or we don’t get paid) • This helps to avoid mission drift, feature creep & a userfocus (it must be ‘cool’; we must exploit viral marketing) Heavyweight Exploitation: • (Typically) public-sector bodies in large consortia • ‘Worthy’ but most definitely not ‘cool’ • Focus groups; advisory bodies and need to address multiple political & cultural pressures stifle innovation • Academic organisations cause drift towards addressing intellectually challenging problems • Inability to respond quickly to technological & cultural changes A Daily Mail stereotype of public sector IT development, or a valid of national development activities?

Dapper Pipes Home is Page RSS Feed Mashup Editor UK University Locator (unfunded) What can we do? • Explore Yahoo Pipes as a lightweight development tool • Explore Dapper (and Dapplications) as a lightweight scraping tool (e.g. exploit microformats) • Explore existing Dapplications (e.g. magg) • Geo-location services are ripe for exploiting (and do you need to fund this?)

Reflections on Nick Poole’s vision: NP: We should place a 2-year moratorium on new projects, programmes and initiatives & focus public funds instead on sustained investment in core capacity building and skills development BK: We should place a 2-year moratorium on large-scale new projects, programmes and initiatives and focus public funds instead on sustained investment in core capacity building small-scale innovation and skills development NP: Significant investment should be made in 3-4 high-value, high- density destination sites such as the 24 Hour Museum which act as 'ambassadors' for our sector in the online environment BK: Small-scale investment should be made in 3-4 low-cost, high-density mashup sites such as the 24 Hour Museum alongside encouragement to 3rd party 'ambassadors' for our sector (e.g. YouTube).

Adopt a relaxed conversational tone. Admit your mistakes. (i.e. don’t tell) • Maximise routes to content. Develop as many aggregations as possible reflecting as many people, places topics, channels, networks and time as possible. • Let people paste your content on the walls of their virtual homes. YouTube is an excellent example of this. • Link to discussions on the web, don’t host them… Only host web-based discussions where there is a clear rd party services) rationale.

We’re JISC reliant on large funds from the EU This doesn’t fit our research agenda This Web 2.0 thing is simple to use and can provide lots of benefits! Adapted from Washington Post cartoon A centre of expertise in digital information management 9 WeJISC have to own the data, the metadata, the software Google might go bankrupt www.ukoln.ac.uk Issues Some issues for discussion: • Would a heavyweight Semantic Web recommendation be appropriate at present? • Is a recommendation for a top-down approach appropriate in a Web 2.0 environment? • Can we regard Web 2.0 as a testbed rather than a solution? • If a user-focussed approach is advisable, do we have concrete evidence that a heavyweight solution (a) is needed and (b) will be used? • What lessons can be learnt from previous cultural heritage development activities? In reality we’ll probably have both bottom-up and top-down approaches. A inchallenge will be A centre of expertise digital information management www.ukoln.ac.uk 10
