    6. 6. JISC Information Environment <ul><li>… a vast and sometimes bewildering range of potential sources of electronic information. Each source of information has its own name, its own interface, features and search facilities. Little wonder, then, that many users remain unaware of their existence or fail to discover their value for their own learning, teaching or research. </li></ul><ul><li>A key challenge is therefore to achieve a managed, coherent and shared information environment that will overcome these obstacles. </li></ul><ul><li>Being able to cross-search and use customised, value added and other services will considerably simplify users’ interactions with online resources. This should encourage take-up and greatly improve means of accessing these resources. </li></ul><ul><li>… these activities need to be based on standards for the creation, access, use, preservation and interoperability of networked resources. </li></ul><ul><li>http://www.jisc.ac.uk/index.cfm?name=ie_home </li></ul>
    7. 7. JISC Information Environment <ul><li>Most content providers will already offer a Web site through which end-users can access their content. To be a part of the JISC-IE, content providers also need to support machine oriented interfaces to their resources. </li></ul><ul><ul><li>Support searching using Z39.50/SRW </li></ul></ul><ul><ul><li>Support metadata harvesting using OAI-PMH </li></ul></ul><ul><li>Andy Powell </li></ul><ul><li>5 step guide to becoming a content provider in the JISC Information Environment </li></ul><ul><li>http://www.ariadne.ac.uk/issue33/info-environment </li></ul>Hub Workshop 2009
    8. 8. E-GIF, open source and open standards <ul><li>e-GIF version 6.1 (18 th March 2005) </li></ul><ul><ul><li>The e-Government Interoperability Framework (e-GIF) sets out the government’s technical policies and specifications for achieving interoperability… across the public sector. </li></ul></ul><ul><ul><li>There is a strategic decision to adopt XML and XSL as the core standards for data integration and management. </li></ul></ul><ul><ul><li>It is a pragmatic strategy that aims to reduce cost and risk for government systems while aligning them to the global Internet revolution. </li></ul></ul><ul><ul><li>http://www.govtalk.gov.uk/documents/eGIF%20v6_1(1).pdf </li></ul></ul><ul><li>Open Source, Open Standards and Re–Use: Government Action Plan </li></ul><ul><ul><li>http://www.netvibes.com/cabinetoffice#Open_Source </li></ul></ul>Hub Workshop 2009

    11. 11. The Distributed Hub Flickr cc licence : Thomas Hawk The main goal of a distributed computing system is to connect users and resources in a transparent , open, and scalable way. Ideally this arrangement is drastically more fault tolerant and more powerful than many combinations of stand-alone computer systems. [Wikipedia] <ul><li>Administration interface </li></ul><ul><li>Customisable web front-end </li></ul><ul><li>Machine-to-machine interfaces </li></ul><ul><li>Data Creation Template </li></ul><ul><li>Local control </li></ul><ul><li>Technical support locally </li></ul><ul><li>Hub team support </li></ul>
    12. 12. Spokes software <ul><li>Offers a means of storing and sharing archival descriptions in XML </li></ul><ul><li>Provides machine-to-machine access to the descriptions through Z39.50 and SRU (Search and Retrieve via URL) & OAI-PMH for harvesting records </li></ul><ul><li>Provides a customisable Web search interface </li></ul><ul><li>Is open source and based on open standards </li></ul><ul><li>Includes a data creation and editing template </li></ul>
    13. 13. Anatomy of a Spoke Hub Workshop 2009 EAD XML files Web search interface Direct searching access for other applications through standards-based machine-to-machine protocols … Including the central Hub! Z39.50 SRU Cheshire indexes of EAD data HTTP
    14. 14. Spokes indexes The database will provide indexes based on the following standards: Data standard Data field(s) cql.anywhere full text dc.description unittitle, controlaccess, and scopecontent fields dc.title collection title (titleproper) dc.creator creator of the collection dc.identifier eadid dc.date unitdate dc.subjects controlaccess fields bath.name personal, family, corporate and geographic names bath.personalName personal names bath.corporateName corporate names bath.geographicName geographic names bath.genreForm genre

    23. 24. The National Archives Network <ul><li>‘ Our vision of the future of British archives is of a flow of archival information which takes account of all the opportunities offered by digital networks and offers opportunity for exploration - historical, personal, social - to the broadest possible range of people wherever they can use it - in the home, the classroom or the office.’ </li></ul>Hub Workshop 2009 British Archives: The Way Forward (NCA, 2000) A comprehensive national resource discovery mechanism
    24. 25.

    29. 30. Shortcomings of the NAN <ul><li>We don’t have a single national network </li></ul><ul><li>Differences in data structure; content; search capabilities; look and feel </li></ul><ul><li>Strands are not fully interoperable </li></ul><ul><li>Politics, funding and willpower may not combine in favour of this approach </li></ul><ul><li>The landscape has changed substantially since 2000 – maybe this solution is no longer appropriate? </li></ul>Hub Workshop 2009
