Contents Introduction • Introduction • About me • About this talk • The National Programmes (provider’s perspective) • The technical standards • The support infrastructure • What We Learnt • What succeeded, what failed and what we discovered along the way • What Should We Do In The Future • What do we do next?
About This Talk Introduction • Talk is based on experiences of national programmes: • eLib • NOF-digi • DNER/IE • Michael • Common characteristics: • Interoperability through open standards • Managed view of roadmap • Issues: • Did we get it right? • Are there alternative approaches?
The eLib Programme • eLib Programme: • Response to the Follet review, 1993 • Initial budget of £15m over 3 years • 60+ projects funded • Areas covered: • Document Delivery • Access To Network Resources • Training & Awareness • Electronic Journals • Digitisation / Images • Electronic Short Loan Collections • On Demand Publishing • Pre-Prints and Grey Literature • Supporting Studies
eLib Standards Guidelines • eLib Standards Guidelines: • Provides recommendations for selection & use of standards • Strongly encouraged where relevant • Covered: • Data communications • Data interchange • Metadata • Search & retrieve • Security, authentication & payment services
Editors: Chris Rusbridge Lorcan Dempsey,& Ann Mumford (myself as a contributor) eLib Standards • Things we don’t care about (?): • Email (SMTP, not X.400), … • Areas we correctly hedged our bets: • GIF is OK, keep eye on PNG • Areas we were evasive about: • PostScript & PDF • Areas we got wrong: • “It is anticipated that SGML will be a key standard ... Projects are encouraged to .. agree or, where necessary, develop document type definitions” • “projects should … supply a URL for public services, and be prepared to adopt URNs when they are stabilised” • Standards which seem to have disappeared: • CGM
eLib Standards version 2 • eLib Standards version 2 • Published in 1998 (2 years after v 1) • Introduced a template for descriptions Relevant standards: Comments: Consensus: • Templates on recommended standards complemented by technical summaries – and speculation e.g. “HTTP-NG should support more secure authentication and encryption”
Beyond The Standards • Cross-Searching: The Vision • whois++ lightweight distributed cross-searching protocol • ROADS: Open source software used by most eLib subject gateways (e.g. SOSIG) • Z39.50: More heavy-weight solution used in library context • eLib SBIGs/RDN: implementation in a distributed environment (with departmental providers) • Cross-Searching: Today’s Reality • Intute: Centralised database, distributed data collection. Cross-searching interfaces, but how widely used? Note dangers of using standards outside of DL programmes – JISC Web site upgrade mandated Z39.50 support
Later, in NOF-digitise • NOF-Digitise programme: • Ran from August 1999 to December 2004 • £50 million funding to put information that supports lifelong learning into digitised form. • Brought together wide range of partnerships & organisations • NOF Technical Advisory Service (NOF TAS) provided: • Informed support and advocacy of Technical Standards and Guidelines • Assistance in achieving standards compliance • Detailed and project-specific advice • Repository of standard and generic advice • Provide by UKOLN and AHDS
Development Culture • Different culture to HE digital library development community: • Tell us the standards which we must mandate • Caused problems: • “NOF-digi project Web sites must have 24x7 availability” – very expensive! Requirement was availability at weekends! • Recommended standards weren’t mature (e.g. SMIL) whereas proprietary solutions (Flash) provided compelling user services • Providing pragmatic solutions: • “NOF-digi project Web sites should seek to maximise their uptime” • Quarterly reporting template provided a get-out clause: “You must (a) describe the areas in which compliance will not be achieved; (b) explain why compliance will not be achieved (including research on appropriate open standards); (c) describe your migration strategies to ensure compliance in the future and (d) how the migration may be funded”
Minerva Experience • Minerva technical guidelines: • EU-funded • Built on eLib/NOF/JISC IE resources • Initially edited by UKOLN • Continued to promote plausible: • Standards • Best practices • which failed to take off
Compliance Issues • What does must mean? • You must comply with HTML standards • What if I don't? • What if nobody does? • What if I use PDF? • You must clear rights on all resources you digitise • You must provide properly audited accounts • What if I don't? JISC 5/99 programme ~80% of project home pages were not HTML compliant There is a need to clarify the meaning of mustand for an understandable, realistic and reasonable compliance regime
QA Focus • QA Focus: • JISC-funded project provided by UKOLN and (initially) TASI, then AHDS from 2002-2004 • What QA regime should JISC provide for its development programmes? What actions should be taken if standards not conformed with? • Recommendations: • Self-assessment, not external validation (projects explained complexities of standards-compliance) • Build on culture of sharing and openness • Have a pragmatic view of ‘open standards’ • Understand complexities of non-conformance / ‘failure’: • The standard failed, not the project • The standard may be too expensive to deploy • Alternatives may become available
Why Open Standards? • 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 But (thinking the unthinkable): • Do open standards deliver? • What happens if open standards fail? • What is an open standard? • Is the only alternative to open standards use of proprietary solutions?
… 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!?
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; … What is An Open Standard? • Which of the following are open standards today (and were open standards in 2006)? • XHTML 1 PDF Flash • Java MS Word RSS (1.0/2.0)
Is RSS An Open Standard? RSS Example • 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 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?
RSS – Governance Issues RSS Example • Governance Issues: • RSS 1.0 spec 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." • 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 – Summary RSS Example • To summarise : • 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 • Need for a more sophisticated approach such as model in “A Contextual Framework For Standards”, WWW 2006
The Context • There will be a context to use of standards: • The intended use: • Mainstream Innovative / research • Key middleware component Small-scale deliverable • Organisational culture: • HE vs FE Teaching vs Research • Service vs Development … • Available Funding & Resources: • Significant funding & training to use new standards • Minimal funding - current skills should be used • … Contextual Issues An open standards culture is being developed, which is supportive of use of open standards, but which recognises the complexities and can avoid mistakes made in the past

Note that one size doesn't always fit all
The Standards Catalogue • The information provided aims to be simple and succinct (but document will still be large when printed!) • Standard: Dublin Core • About the Standard: Dublin Core is a metadata standard made up … • Version: New terms are regularly added to … • Maturity: Dublin Core has its origins in workshops held … • Risk Assessment: Dublin Core plays a key role …. It is an important standard within the context of JISC development programmes. • Further Information: • DCMI, <http://dublincore.org/> • … • Author: Pete Johnston, UKOLN • Contributor: • Date Created: 04 Oct 2005 • Update History: Initial version. Example Note that as the standards catalogue is intended for wide use the contents will need to be fairly general The Standards Catalogue is deemed important – but there’s a still lack of understanding of the contextual model
What If Web 2.0 Changes Everything? • “Web 2.0 Changes Everything” – what if this is true? The “Higher Education in a Web 2.0 World” report suggests that Senior Managers in HE may feel this to be the case • “Network is the platform” / The Cloud • Web infrastructure becomes the infrastructure (HE follows, no longer leads) • Growing importance of informal learning • Growing importance of informal networking • Growing reluctance to travel (travelling to CILIP-S on par with dodgy MPs’ expenses claims?) • …
The DNER/IE Diagram • Web 2.0 in the context of Andy Powell’s famous IE diagram (early version shown) ..which later was developed further
My Take • My Vision • In 2001 I suggested that application services could be provided ‘out there’ (in The Cloud). • I speculated about the JISC Spellchecker and JISC ‘delicious’ services What I Missed! What I thought about but failed to articulate (it seemed (a) Thatcherite out-sourcing & (b) too complex) was commercial provision of the services & large-scale apps e.g. Google Docs
Services In ‘The Cloud’ • Will Web 2.0 services in ‘The Cloud’ make national initiatives irrelevant? • Or will there be a mix of institutional, national and global providers of solutions? • Or will institutional & national services make use of infrastructure in ‘The Cloud’?
What About The Developers? • In the old days: • Development was slow and required significant levels of funding • Funders and budget holders could manage development process • Today: • Web infrastructure more mature (standards, services, APIs, …) • Light-weight is ‘cool’ • Developers don’t want 3 year projects (and associated bureaucracy) – but food & drink are good!
What Can Be In A Weekend? • Tony Hurst’s visualisations of MPs expenses claims
Community Matters • Importance of developer community now being appreciated: • In JISC Circles (cf dev8d week; Mashed Library events; Rapid Innovation Call) • In Museums sector (cf. Mashed Museum events) • In commercial sector (cf barcamps) • In government circles (cf. Government barcamps) • … http://dev8d.jiscinvolve.org/2009/03/30/ Dev8D: Developer Happiness Days event sponsored by JISC. See <http://dev8d.jiscinvolve.org/>
Deployment Strategies • Interested in using Web 2.0 in your organisation? • Worried about corporate inertia, power struggles, etc? • There’s a need for a deployment strategy: • Addressing business needs • Low-hanging fruits • Encouraging the enthusiasts • Gain experience of the browser tools – and see what you’re missing! • Staff training & development • Impact assessment and measurement • Risk and opportunity management strategy • Critical Friends and friendly critics • Culture of sharing • …
Risk Management Strategies • JISC infoNet Risk Management infoKit: “In education, as in any other environment, you can’t decide not to take risks: that simply isn’t an option in today’s world. All of us take risks and it’s a question of which risks we take” • Examples of people who are likely to be adverse stakeholders: • People .. required to commit resources to the project • People who fear loss of control over a function or resources • People who will have to do their job in a different way • People who will have to carry out new functions • People who will have to use a new technology • ..
Paul Walk (UKOLN) was described as a ‘critical friend’ of JISC See <http://dev8d.jiscinvolve.org/2009/02/10/five-minute-interview-paul-walk/> Critical Friends • JISC U&I programme is encouraging establishment of “Critical Friends” See <http://critical-friends.org/>

(various stakeholders Costs (various stakeholders Using The Framework (2) • Use of approach with standards: doing nothing (today) might be an option! Semantic Web No standard
The Assumptions • Standards: • Interoperability through open standards • Avoidance of proprietary lock-in & other benefits • All we need is to identify the correct open standards • This will save us time, money & deliver rich functionality and usable & useful services • Development: • The developers can then simply use the standards • This will also provide seamless evolution to new standards
Challenging The Assumptions • Maybe we want: • To challenge the unthinking assumptions in national development programmes –using evidence rather than assertions • The benefits promised (but not necessarily delivered) by open standards • An understanding that it’s not a binary open standards vs proprietary world • The world may choose good enough, whilst we want to provide the best • To develop user-focussed services which the commercial sector seems to be better at • To recognise the importance of the developers’ perspective And we should also challenge these views!
