Thinking The Unthinkable
Interoperability Through
Open Standards! Really?
Brian Kelly                           About This Talk
UKOLN                                 This talk explores some of the
University of Bath                    areas in which open standards are
Bath                                  limited and invites discussion on
Email                                 JISC‟s “Interoperability though
B.Kelly@ukoln.ac.uk                   open standards” approach.

                     JISC's development programmes:
                        • Traditionally based on use of open standards to:
                                 Support interoperability
                                 Maximise accessibility
                                 Avoid vendor lock-in
                                 Provide architectural integrity
                                 Help ensure long-term preservation

    Open Standards   … 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
                     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   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.

    Open Standards   What is an Open Standard?
                     Which of the following are open standards?
                       • XHTML 1          PDF            Flash
                       • Java             MS Word        RSS (1.0/2.0)
                     UKOLN's "What Are Open Standards?" briefing paper
                     refers to characteristics of open standards:
                       • Neutral organisation which 'owns' standard &
                         responsible for roadmap
                       • Open involvement in standards-making process
                       • Access to standard freely available
                       •…

                     Note these characteristics do not apply equally to all
                     standards bodies e.g. costs of BSI standards; W3C
                     membership requirements; …

    Compliance   Compliance Issues
                 What does must mean?
                   • You must comply with HTML standards
                             What if I don't?                JISC 5/99 programme
                             What if nobody does?            ~80% of project home
                             What if I use PDF?              pages were not HTML
                                                              compliant
                     • You must clear rights
                       on all resources you digitise
                     • You must provide properly audited
                       accounts
                             What if I don't?
                  There is a need to clarify the meaning of must
                  and for an understandable, realistic and reasonable
                  compliance regime

    RSS Example   Is RSS An Open Standard?
                  Is RSS an open standard ("are RSSs open standards")?
                     RSS 1.0 (RDF Site Summary)
                        • XML application using RDF model
                        • Developed by Aaron Schwarz
                     RSS 2.0 (Really Simple Syndication)
                        • XML application using simpler model
                        • Developed by Davey Winer
                  Note that RSS is a widely used and popular application;
                  with usage growing through its key role in Podcasts

                  Issues:
                      • Are these open standards?
                      • Are they reliable and robust enough to build
                        mission-critical services on?
                      • Is there a clear roadmap for the future? www.ukoln.ac.uk

     RSS Example   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. At 14 he co-authored the RSS 1.0
                       specification, now used by thousands of sites to
                       notify their readers of updates.“ (Web page now changed)
                    • 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."

     RSS Example   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 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):
                   "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."


                   Note Wikipedia has useful links to the history and
                   politics of RSS

     RSS Example   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

                                                         How does this compare with the

     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 middleware; IBM
              took on MS 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?
