… But Don't Always Work  There's a need for flexibility: Learning the lesson from OSI networking protocols Today: Is the Web (for example) becoming over-complex "Web service considered harmful" The lowercase semantic web / Microformats Lighter-weight alternatives being developed Responses from the commercial world Open Standards Other key issues What is an open standard? What are the resource implications of using them? Sometimes proprietary solutions work (and users like them). Is it politically incorrect to mention this!?

Open Standards: an EU View European Interoperability Framework for pan-European eGovernment Services defines open standards as: The standard is adopted and will be maintained by a not-for-profit organization The standard specification document is available either freely or at a nominal charge The intellectual property of the standard is made irrevocably available on a royalty free basis No constraints on the re-use of the standard.

RSS – Governance Issues Governance Issues: RSS 1.0 specification maintained by Aaron Schwartz: " Aaron Swartz is a teenage writer, hacker, and activist. He was a finalist for the ArsDigita Prize for excellence in building non-commercial web sites at the age of 13.

RSS 1.0 – Roadmap Issues RSS 1.1: In Jan 2005 RSS 1.1 draft released: "[we] expressed our mutual frustrations with 1.0 …, we decided that rather than lauch (sic) ... another … diatribe against the quality of the RSS 1.0 spec, … [we would] simply write a new specification ourselves. " But it is no longer being developed: Draft technically good (addressed ambiguities & interoperability flaws) but political reaction apathetic RSS 2.0 has (a) better acronym and (b) momentum (through Podcasting) And RSS 2.0 sounds newer RSS 3.0 (joke?) proposal has caused confusion and arguments on Slashdot and elsewhere RSS Example

RSS 1.1:

In Jan 2005 RSS 1.1 draft released:

"[we] expressed our mutual frustrations with 1.0 …, we decided that rather than lauch (sic) ... another … diatribe against the quality of the RSS 1.0 spec, … [we would] simply write a new specification ourselves. "

But it is no longer being developed:

Draft technically good (addressed ambiguities & interoperability flaws) but political reaction apathetic

RSS 2.0 has (a) better acronym and (b) momentum (through Podcasting)

And RSS 2.0 sounds newer

RSS 3.0 (joke?) proposal has caused confusion and arguments on Slashdot and elsewhere

RSS 2.0 – Roadmap Issues RSS 2.0: Spec published by Harvard Law School with a Creative Commons licence RSS-Board YahooGroups used for governance body Many arguments (most recently on proposal to expand board in April 2006): Note Wikipedia has useful links to the history and politics of RSS "Winer has now decided that the board doesn't exist and never had authority over the RSS specification, even though it has published six revisions from July 2003 to the present. I don't agree, but now that the board's fully public, we're in a position to make his wish a reality." RSS Example

RSS 2.0:

Spec published by Harvard Law School with a Creative Commons licence

Many arguments (most recently on proposal to expand board in April 2006):

Podcasting Lots of interest (recording lecturers; student created Podcasts; marketing; …) A simple enhancement to RSS 2.0 (syndication sound/movie file, and not just text) <itunes:author>Henry Rzepa</itunes:author> <description>Wiki Workshop</description> … <itunes:category text=&quot;Education&quot;> <itunes:category text=&quot;Higher Education&quot;/> </itunes:category> <itunes:keywords>Chemistry, … </itunes:keywords> <itunes:explicit>no</itunes:explicit> But: Syndicates MP3 (Ogg, who cares?)

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 RSS Example

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

Isn’t Slideshare Good Enough? Slideshare.net is a good example of a digital repository for slides, which is easy-to-use and supports community discussion, folksonomies, etc. How does this compare with the traditional JISC approach (see Andy Powell’s Blog ). http://slideshare.net/lisbk/profile Note: The slides can be embedded PowerPoint & ODF supported - but not XML or PDF! NB looking for other slides about “standards” finds Stephen Downes critique of standards http://www.ukoln.ac.uk/web-focus/events/ workshops/webmaster-2006/talks/metcalfe/

IT Development vs IT as a Commodity Web 2.0 is bringing IT as a commodity: Amazon provide disk storage, CPU, applications, … Google & Yahoo provide many application services If IT becomes a commodity, who cares about the production processes? Open standards = ethical electricity? http://www.amazon.com/ … Note that Slideshare.net uses Amazon CPUs – see the URL when uploading

Amazon provide disk storage, CPU, applications, …

If IT becomes a commodity, who cares about the production processes?

Open standards = ethical electricity?

Standardistas – Good or Bad? If standards are great: Why are ‘standardistas’ getting a bad name? Why are there so many Blogs about conflicts in W3C? … http://www.molly.com/2006/02/23/ how-to-sniff-out-a-rotten-standardista/ Are standards like New Labour? We thought it was all great in 1997, but we’re now disillusioned – although we sometimes recognise it’s better than the alternative!

If standards are great:

Why are ‘standardistas’ getting a bad name?

Why are there so many Blogs about conflicts in W3C?

Issues For Discussion Some possible areas to discuss: Is there a limited scope in which open standards are critical (cf. “open source is best for e-science; IBM took MS on in the office environment and lost”) Standardisation is often an intensively political process – so is it surprising if open standards can be so flawed? User-focussed or standards-based development: how do we respond if they’re in conflict? Why are development projects deliverables often perceived as inferior? “ Interoperability through open standards” Is this the correct message to give? If not, what should we say?
