Digital library and MLE integration - where are we now and where do we want to be?

  1. 1. UKOLN is supported by: Digital library and MLE integration where are we now and where do we want to be? Andy Powell, UKOLN, University of Bath [email_address] UCISA TLIG-SDG User Support Conference 2004, Exeter www.bath.ac.uk a centre of expertise in digital information management www.ukoln.ac.uk
  2. 2. Contents <ul><li>current developments in five institutional ‘service areas’ </li></ul><ul><ul><li>external information services </li></ul></ul><ul><ul><li>library </li></ul></ul><ul><ul><li>computing services / Web support </li></ul></ul><ul><ul><li>e-Learning </li></ul></ul><ul><ul><li>MIS, registry, student records, finance, etc. </li></ul></ul><ul><li>standards bodies/activities </li></ul><ul><li>technical options for joining stuff together </li></ul><ul><li>broad and shallow! </li></ul><ul><ul><li>but highlighting RSS and OpenURL </li></ul></ul>
  3. 3. Institutional service areas… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content
  4. 4. External content <ul><li>wide range of information and other content coming into the institution from outside </li></ul><ul><ul><li>made available thru JISC ‘site licensing’ deals, national data centres, elsewhere </li></ul></ul><ul><li>primary focus of the JISC’s ‘information environment’ activity </li></ul>External content
  5. 5. The ‘problem’… <ul><li>end-user often has access to large number of heterogeneous collections - full-text, A&I, images, video, data, etc. </li></ul><ul><li>however, experience of these collections is less than optimal: </li></ul><ul><ul><li>end-users not aware of available content </li></ul></ul><ul><ul><li>end-user has to interact with (search or browse) multiple different Web sites to work across range of content </li></ul></ul><ul><ul><li>content ‘discovery’ services not joined-up with ‘delivery’ services </li></ul></ul>
  6. 6. Simple scenario <ul><li>consider a researcher searching for material to inform a research paper on HIV and/or AIDS </li></ul><ul><li>he or she searches for ‘hiv aids’ using: </li></ul><ul><ul><li>the RDN, to discover Internet resources </li></ul></ul><ul><ul><li>ZETOC, to discover recent journal articles </li></ul></ul><ul><li>(and, of course, he or she may use a whole range of other search strategies using other services as well) </li></ul>
  7. 9. Issues <ul><li>different user interfaces </li></ul><ul><ul><li>look-and-feel </li></ul></ul><ul><ul><li>subject classification, metadata usage </li></ul></ul><ul><li>everything is HTML – human-oriented </li></ul><ul><ul><li>difficult to merge results, e.g. combine into a list of references </li></ul></ul><ul><ul><li>difficult to build a reading list to pass on to students </li></ul></ul><ul><ul><li>need to manually copy-and-paste search results into HTML page or MS-Word document or desktop reference manager or … </li></ul></ul>
  8. 10. The problem space… <ul><li>from perspective of ‘data consumer’ </li></ul><ul><ul><li>need to interact with multiple collections of stuff - bibliographic, full-text, data, image, video, etc. </li></ul></ul><ul><ul><li>delivered thru multiple Web sites </li></ul></ul><ul><ul><li>few good cross-collection discovery services (apart from Google, but much of the licensed content is part of the invisible Web and therefore not available to Google) </li></ul></ul><ul><li>from perspective of ‘data provider’ </li></ul><ul><ul><li>few agreed mechanisms for disclosing availability of content </li></ul></ul>
  9. 11. UK JISC IE context… <ul><li>206 collections and counting… (Hazel Woodward, e-ICOLC, Helsinki, Nov 2001) </li></ul><ul><ul><li>Books: 10,000 + </li></ul></ul><ul><ul><li>Journals: 5,000 + </li></ul></ul><ul><ul><li>Images: 250,000 + </li></ul></ul><ul><ul><li>Discovery tools: 50 + </li></ul></ul><ul><ul><ul><li>A & I databases, COPAC, RDN, … </li></ul></ul></ul><ul><ul><li>National mapping data & satellite imagery </li></ul></ul><ul><li>plus institutional content (e-prints, research data, library content, learning resources, etc.) </li></ul><ul><li>plus content made available thru projects – 5/99, FAIR, X4L, … </li></ul><ul><li>plus … </li></ul>
  10. 12. A solution… the JISC IE <ul><li>an ‘information environment’ </li></ul><ul><li>framework of machine-oriented services allowing the end-user to </li></ul><ul><ul><li>discover , access , use , publish resources across a range of content providers </li></ul></ul><ul><ul><li>move away from lots of stand-alone Web sites... </li></ul></ul><ul><li>content providers expose metadata for </li></ul><ul><ul><li>searching, harvesting , alerting </li></ul></ul><ul><li>develop end-user services and tools that bring stuff together… </li></ul><ul><li>…based on open ‘standards’ </li></ul>
  11. 13. End-user services and tools <ul><li>generally means ‘portals’… </li></ul><ul><ul><li>‘ library’ portals or metasearch tools (e.g. Encompass, MetaLib or ZPortal) </li></ul></ul><ul><ul><li>‘ subject’ portals developed within academia </li></ul></ul><ul><ul><li>‘ institutional’ portals (uPortal) </li></ul></ul><ul><li>… but also other stuff </li></ul><ul><ul><li>reading list and other tools in VLE (possibly externally hosted, e.g. Sentient Discover) </li></ul></ul><ul><ul><li>commercial/publisher services (ISI Web of Knowledge, ingenta, Bb Resource Center, etc.) </li></ul></ul><ul><ul><li>OpenURL resolvers (e.g. SFX) </li></ul></ul><ul><ul><li>personal desktop reference manager (e.g. Endnote) </li></ul></ul>
  12. 14. Link resolvers <ul><li>‘ discovery’ is only part of the problem… </li></ul><ul><li>in the case of books, journals, journal articles, end-user wants access to the most appropriate copy </li></ul><ul><li>need to join up discovery services with access/delivery services (local library OPAC, ingentaJournals, Amazon, etc.) </li></ul><ul><li>need localised view of available services </li></ul><ul><li>linking services that provide access to the most appropriate copy </li></ul><ul><ul><li>user and institutional preferences, cost, access rights, location, etc. </li></ul></ul>
  13. 15. Technologies <ul><li>global, standards-based, cross-domain solutions – Web services… </li></ul><ul><li>cross-searching </li></ul><ul><ul><li>Z39.50 – Bath Profile, a profile of Z39.50 </li></ul></ul><ul><ul><li>SRW (Search and Retrieve Web-service) (SOAP implementation of Z39.50) </li></ul></ul><ul><li>harvesting </li></ul><ul><ul><li>OAI-PMH - Open Archives Initiative Protocol for Metadata Harvesting </li></ul></ul><ul><li>alerting </li></ul><ul><ul><li>RSS - RDF/Rich Site Summary </li></ul></ul><ul><li>linking </li></ul><ul><ul><li>OpenURL </li></ul></ul>
  14. 16. Institutional service areas… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content
  15. 17. Library <ul><li>management of collection </li></ul><ul><ul><li>migration from hardcopy journals to externally held e- collection </li></ul></ul><ul><li>management of institutional assets - eprint archives, edata archives </li></ul><ul><ul><li>role in cataloguing assets </li></ul></ul><ul><li>catalogue - gateway/portal to external (and internal) content </li></ul><ul><li>‘ managing agent’ for ATHENS </li></ul><ul><li>preservation </li></ul><ul><li>link resolvers </li></ul>Library
  16. 18. Linking within the ‘collection’ <ul><li>the context </li></ul><ul><ul><li>distributed information environment (e.g. the JISC IE) </li></ul></ul><ul><ul><li>multiple A&I and other discovery services </li></ul></ul><ul><ul><li>rapidly growing e-journal collection </li></ul></ul><ul><ul><li>need to interlink available resources </li></ul></ul><ul><li>the problem </li></ul><ul><ul><li>links controlled by external info services </li></ul></ul><ul><ul><li>links not sensitive to user’s context (appropriate copy problem) </li></ul></ul><ul><ul><li>links dependent on vendor agreements </li></ul></ul><ul><ul><li>links don’t cover complete collection </li></ul></ul>
  17. 19. The problem <ul><li>the context </li></ul><ul><ul><li>distributed information environment (e.g. the JISC IE) </li></ul></ul><ul><ul><li>multiple A&I and other discovery services </li></ul></ul><ul><ul><li>rapidly growing e-journal collection </li></ul></ul><ul><ul><li>need to interlink available resources </li></ul></ul><ul><li>the REAL problem </li></ul><ul><ul><li>libraries have no say in linking </li></ul></ul><ul><ul><li>libraries losing core part of ‘organising information’ task </li></ul></ul><ul><ul><li>expensive collection not used optimally </li></ul></ul><ul><ul><li>users not well served </li></ul></ul>a library perspective!
  18. 20. The solution… <ul><li>do NOT hardwire a link to a single service on the referenced item (e.g. a link from an A&I service to the corresponding full-text) </li></ul><ul><li>BUT rather </li></ul><ul><ul><li>provide a link that transports metadata about the referenced item </li></ul></ul><ul><ul><li>to another service that is better placed to provide appropriate links </li></ul></ul>OpenURL OpenURL resolver (link server)
  19. 21. Non-OpenURL linking resolution of metadata into a link (typically a URL) A&I service document delivery service link to referenced work . reference link destination link source

  32. 38. Comp. Serv. / Web support <ul><li>Content Management System (CMS) – use of XML </li></ul><ul><ul><li>blogs, wikis, … </li></ul></ul><ul><li>development/delivery of portal - uPortal </li></ul><ul><li>campus infrastructure </li></ul><ul><ul><li>search engine, but often with fairly narrow coverage (home grown (Ht:/Dig) vs. commercial vs. externally hosted (Google)) </li></ul></ul><ul><ul><li>internal AAA (authentication, authorisation and accounting) infrastructure </li></ul></ul><ul><ul><li>network, shared filestore, groupware, etc. </li></ul></ul>Computing Services/ Web support team
  33. 39. uPortal <ul><li>framework for building institutional portal </li></ul><ul><ul><li>single sign-on </li></ul></ul><ul><ul><li>integrated and personalised access to multiple ‘channels’ </li></ul></ul><ul><ul><li>portlet model </li></ul></ul><ul><ul><li>multiple standards for ‘portlets’ but some trend towards use of WSRP (Web Services for Remote Portlets) </li></ul></ul><ul><ul><li>RSS often used to carry portlet content </li></ul></ul>portlet http://www.uportal.org/
  34. 40. What is RSS? <ul><li>simple XML application for sharing (syndicating) ‘news’ feeds on the Web </li></ul><ul><li>RDF Site Summary or Rich Site Summary (depending on who you ask) </li></ul><ul><li>‘news’ can be interpreted quite loosely, e.g. new items added to database, ‘to do’ lists, timetable/lists of meetings, etc. </li></ul><ul><li>uses ‘channel’ and ‘item’ terminology </li></ul><ul><li>a ‘channel’ is an XML document that is made available on a Web-site – to update the channel, simply update the XML </li></ul>http://www.eevl.ac.uk/rss_primer/
  35. 41. What is RSS? (2) <ul><li>each ‘item’ has simple metadata (title, description) and URL link to resource (news story or whatever) </li></ul><ul><li>RSS also provides channel branding (logo, etc.) </li></ul><ul><li>fairly widespread usage </li></ul><ul><li>easy to use within ‘portals’ (e.g. uPortal) </li></ul><ul><li>lots of software and toolkits available </li></ul><ul><li>some experimental use as encoding format for ‘reading/resource lists’ in e-Learning </li></ul>
  36. 42. Institutional service areas… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content
  37. 43. e-Learning <ul><li>delivery of VLE </li></ul><ul><li>development of ‘managed learning environment’ MLE (integration with MIS/registry, etc.) </li></ul><ul><li>separation of content into backend learning object repositories </li></ul><ul><li>development of whole range of supporting standards, primarily thru IMS </li></ul>e-Learning
  38. 44. IMS <ul><li>global consortium defining open standards for delivery of online distributed learning activities: </li></ul><ul><ul><li>Accessibility </li></ul></ul><ul><ul><li>Competency Definitions </li></ul></ul><ul><ul><li>Content Packaging </li></ul></ul><ul><ul><li>Digital Repositories </li></ul></ul><ul><ul><li>Enterprise </li></ul></ul><ul><ul><li>Learner Information Package </li></ul></ul><ul><ul><li>Meta-data </li></ul></ul><ul><ul><li>Question & Test </li></ul></ul><ul><ul><li>Simple Sequencing </li></ul></ul>http://www.imsglobal.org/
  39. 45. IMS DRI Specifications <ul><li>IMS Digital Repositories Interoperability specifications </li></ul><ul><li>define protocols for interoperability between systems </li></ul><ul><li>machine2machine (i.e. how software components talk to each other over the network) </li></ul><ul><li>how data (and metadata) is transferred </li></ul><ul><li>between VLE and back-end repositories </li></ul><ul><ul><li>learning object repositories and other services that make content available </li></ul></ul>
  40. 46. Why is IMS DRI important? <ul><li>VLE (in some shape or form) likely to become one of key ‘presentation’ services in institutional context </li></ul><ul><li>IMS DRI spec’s fill space between ‘information providers’ and VLEs </li></ul><ul><li>same/similar set of ‘digital library’ standards as endorsed by the JISC IE architecture </li></ul><ul><li>VLE-vendors relatively mainstream </li></ul><ul><li>pushes digital library technologies to new and wider audience </li></ul>
  41. 47. e-Learning <ul><li>recognition that e-Learning systems are complex objects </li></ul><ul><ul><li>trend towards ‘service oriented architectures’ </li></ul></ul><ul><ul><li>breaking the VLE into lots of smaller functional components </li></ul></ul><ul><li>JISC Learning Framework (CETIS), MIT’s OKI, Sakai (alignment of OKI and uPortal) </li></ul>
  42. 48. Service oriented architecture <ul><li>analysis of functional components within large-scale institutional services (library, VLE, student records, etc.) </li></ul><ul><ul><li>delivery of separate, small-scale functional ‘services’ </li></ul></ul><ul><ul><li>rationalisation of ‘shared’ common services (middleware) </li></ul></ul>
  43. 51. Implementation of SOA <ul><li>implementation choices </li></ul><ul><ul><li>J2EE (JavaBeans, etc.) </li></ul></ul><ul><ul><li>JINI (Java APIs) </li></ul></ul><ul><ul><li>.Net </li></ul></ul><ul><ul><li>Web Services (SOAP) </li></ul></ul><ul><li>I think(!)… </li></ul><ul><ul><li>OKI, uPortal, Sakai tend to lean towards Java-based solutions – J2EE </li></ul></ul><ul><ul><li>whereas SOAP perhaps provides a more open, robust and language independent solution? </li></ul></ul>
  44. 52. Web services <ul><li>machine (m2m) interfaces between services on the Web </li></ul><ul><li>underpin many e-commerce activities and the Grid </li></ul><ul><li>a whole new set of acronyms – SOAP, WSDL, UDDI, WSRP </li></ul><ul><li>based on HTTP and XML (i.e. mainstream Web pedigree) </li></ul><ul><li>Google and Amazon APIs </li></ul><ul><li>support both informational (e.g. search) and transactional (e.g. billing) types of service </li></ul>
  45. 53. But… 2 notes of caution? <ul><li>is all this added complexity worthwhile and/or realistic? </li></ul><ul><ul><li>will the market-place support it? </li></ul></ul><ul><li>where does application logic sit in a service oriented architecture? </li></ul><ul><ul><li>need ‘open’ role/process layer to coordinate use of services </li></ul></ul>

  50. 58. HTTP links… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content http://… URLs
  51. 59. HTTP links <ul><li>easy for end-users to create </li></ul><ul><li>bit of a mess… </li></ul><ul><li>…but deep-links (e.g. direct to book record in the library catalogue) will reduce need for end-user to repeat searches </li></ul><ul><li>ongoing maintenance problem – checking for dead links </li></ul><ul><li>hard-wired links are same for everyone </li></ul>

Robot/search engine <ul><li>easily deployed technology </li></ul><ul><li>lots of choice in the market-place (Open source, commercial, externally hosted, etc.) </li></ul><ul><li>not everything is visible to the robot – even within institution (invisible Web) </li></ul><ul><li>can’t easily index some formats (images, video, data, etc.) </li></ul><ul><li>limited search functionality (because of lack of metadata) </li></ul><ul><li>well understood by the end-user </li></ul>
  54. 62. OpenURL links… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content OpenURL links (URLs)
  55. 63. OpenURL links <ul><li>context sensitive – OpenURL resolver can offer different set of links to each user </li></ul><ul><li>harder to create links </li></ul><ul><li>more persistent – change resolver, rather than each link </li></ul><ul><li>up-front investment in OpenURL resolver software (but typically from the library budget!) </li></ul>
  56. 64. Portal – Web services… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content uPortal framework, aggregated content (distributed search)
  57. 65. Portal – Web services <ul><li>aggregate content from multiple sources using distributed search and/or metadata harvesting – SOAP, Z39.50, OAI-PMH </li></ul><ul><li>typically adopted by ‘library’ portals </li></ul><ul><li>likely to be approach adopted by external information suppliers </li></ul><ul><li>likely to be supported by ‘repository’ software within institution </li></ul><ul><li>but may require some in-house development in short term </li></ul><ul><li>learning curve to overcome </li></ul>
  58. 66. Portal – portlets… e-Learning Library Computing Services/ Web support team MIS/ Registry/ Finance/Etc. External content uPortal framework, aggregated user-interface (WSRP)
  59. 67. Portal – portlets <ul><li>aggregate pieces of user-interface from multiple sources </li></ul><ul><li>Web services for Remote Portlets (WSRP) </li></ul><ul><li>RSS </li></ul><ul><li>uPortal appears to be technology leader </li></ul>
  60. 68. Summary <ul><li>all approaches listed above likely to be used/adopted in some form </li></ul><ul><li>RSS and OpenURL look to be being widely adopted </li></ul><ul><li>fairly widespread interest in uPortal </li></ul><ul><li>standardisation happening in multiple arenas (W3C, NISO, IMS, IEEE, OASIS) – tracking standards not easy </li></ul><ul><li>deployment happening in multiple places within institutions – so needs strategic overview of joined up service provision </li></ul>
