He was a finalist for the ArsDigita Prize for excellence in building non-commercial web sites at the age of 13. At 14 he co-authored the RSS 1.0 specification, now used by thousands of sites to notify their readers of updates. " RSS 2.0 specification developed by Dave Winer: " Winer is known as one of the more polarizing figures in the blogging community. … However.. there are many people and organizations who seem unable to maintain a good working relationship with Dave."

A centre of expertise in digital information managementwww.ukoln.ac.uk 12 RSS – Summary What can be learnt: We thought RSS was a great lightweight syndication technology It was – but competing alternatives were developed No clear winner (RSS 1.0's extensibility & W3C's support versus RSS 2.0's simplicity and take-up in Podcasting, iTunes, etc) Conclusions Life can be complex, even with simple standards Technical merit is never enough – market acceptance can change things RSS can still be useful, and interoperability can be provided by RSS libraries supporting multiple formats Conclusions Life can be complex, even with simple standards Technical merit is never enough – market acceptance can change things RSS can still be useful, and interoperability can be provided by RSS libraries supporting multiple formats RSS Example

18. A centre of expertise in digital information managementwww.ukoln.ac.uk 18 Sustainability How do we Sustain, maintain & grow the standards catalogue? Develop a sustainable support infrastructure? Suggestions: More resources for support infrastructure Extend model to related areas to gain buy-in, etc Exploit learning gained by projects, reuse experiences, encourage sharing, etc.: Build on QA Focus approach (briefing docs and case studies) Contractual requirement for projects to produce end-user deliverables and deliverables related to development process Sustainability

24. A centre of expertise in digital information managementwww.ukoln.ac.uk 24 Risk Assessment Model SS=f(SB, S, U, En,..) Selection of appropriate standard (SS) is function of: Standards Body (SB): Maturity, stability, status, openness, responsivity, … Standard (S): Functionality, complexity / ease-of-use, … Users (U): Appropriateness for, benefits to adoption by … Environment (En): Institutional, community, sectoral, … Other factors: Market acceptance: do vendors support it (beyond proof-of-concept open source examples) Risks (am I betting the company of the standard) Exit options (can I easily change my mind) Advocacy (is the world campaigning for it) and threats (is the world criticising for it) Future Work

25. A centre of expertise in digital information managementwww.ukoln.ac.uk 25 Using Risk Assessment Model Using model, what conclusions would you arrive at for: GIF vs PNG? Former has patented algorithm; latter is open and better – but does inertia rule (and limitations in browser support for PNG? PDF vs HTML/CSS? Latter is open and better for reuse but publishing processes prefer control provided by latter (cf this workshop) PowerPoint vs HTML/CSS (e.g. S5) or SMIL? Former is ubiquitous; easier for authors and gives better handouts Semantic Web vs semantic web vs status quo? Promises much, but complex vs simpler approach using existing technologies vs people may be happy with status quo and organisation reluctant to take risks Future Work

26. A centre of expertise in digital information managementwww.ukoln.ac.uk 26 Conclusions To conclude: Open standards is important and use should be encouraged, esp, in public sectors Because of importance, there is a need for a pragmatic approach and not hide behind dogma The contextual approach: Allows scope to address complexities of technologies; deployment environments; etc. Best deployed within a supportive open standards culture Can be extended to other relevant areas We can use Creative Commons for open access to standards information; support materials; etc. which can help sustainability A risk assessment approach can help avoid mistakes in adopting risky open standards Conclusions
