    3. 3. Digital Libraries <ul><li>What is a digital library? </li></ul><ul><li>&quot;Digital libraries are organizations that provide the resources, including the specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities“ (Digital Library Federation, 1999). </li></ul>
    4. 4. Digital Libraries <ul><li>What is the purpose of a digital library? </li></ul><ul><ul><li>to select, </li></ul></ul><ul><ul><li>structure, </li></ul></ul><ul><ul><li>offer intellectual access to, </li></ul></ul><ul><ul><li>interpret, </li></ul></ul><ul><ul><li>distribute, </li></ul></ul><ul><ul><li>preserve the integrity of, and ensure the persistence over time of </li></ul></ul>

    6. 6. Digital Libraries   Purpose Type Access Alexandria Digital Library       NSDL       ACM       Perseus Digital Library      
    7. 15. Digital Libraries: Implications <ul><li>What information do you need to store to support each of these sorts of access? </li></ul><ul><ul><li>Geospatial co-ordinates </li></ul></ul><ul><ul><li>Educational levels </li></ul></ul><ul><ul><li>Author/ publisher </li></ul></ul><ul><ul><li>Title </li></ul></ul>
    8. 16. Digital Libraries: Metadata <ul><li>“ Metadata is data about data. The term refers to any data used to aid the identification, description and location of networked electronic resources.” </li></ul><ul><li>Variety of schemas design to meet local needs but be able to interoperate on some level with other digital libraries </li></ul><ul><ul><li>Examples: MARC 21; DC; IEEE LOM </li></ul></ul>

    13. 21. Digital Asset Management : Strategy <ul><li>Purpose of an asset management strategy </li></ul><ul><ul><li>Who is it for? </li></ul></ul><ul><ul><ul><li>Staff </li></ul></ul></ul><ul><ul><ul><li>Students </li></ul></ul></ul><ul><ul><ul><li>Public </li></ul></ul></ul><ul><ul><li>What is it for? </li></ul></ul><ul><ul><ul><li>Management </li></ul></ul></ul><ul><ul><ul><li>Access </li></ul></ul></ul><ul><ul><ul><li>Preservation </li></ul></ul></ul><ul><ul><li>What is it going to manage? </li></ul></ul><ul><ul><ul><li>College documents [y] </li></ul></ul></ul><ul><ul><ul><li>College learning materials [y] </li></ul></ul></ul><ul><ul><ul><li>External assets [y] </li></ul></ul></ul><ul><ul><ul><li>Research materials </li></ul></ul></ul><ul><ul><ul><li>Finance documents </li></ul></ul></ul><ul><ul><ul><li>Personnel documents </li></ul></ul></ul>
    14. 22. Digital Asset Management : Strategy <ul><li>Development of an digital asset management strategy </li></ul><ul><ul><li>What has to happen to achieve this strategy? </li></ul></ul><ul><ul><ul><li>What issues are implicit in these purposes? </li></ul></ul></ul><ul><ul><ul><li>What issues are implicit in the selection of asset types? </li></ul></ul></ul><ul><ul><li>What are the existing people, practices, and structures? </li></ul></ul><ul><ul><ul><li>How are these assets managed currently? </li></ul></ul></ul><ul><ul><ul><li>How can existing structures be incorporated /used? </li></ul></ul></ul><ul><ul><ul><li>What data already exists electronically? </li></ul></ul></ul><ul><ul><ul><li>Why is being aware of this important? </li></ul></ul></ul><ul><ul><li>The system supports the strategy not the other way around (if you build it without them, they will not come). </li></ul></ul>
    15. 23. Digital Asset Management : Metadata <ul><li>Metadata requirements </li></ul><ul><ul><li>What points of access are required? </li></ul></ul><ul><ul><li>What other information is required? </li></ul></ul><ul><ul><li>Bibliographic (e.g. &quot;a picture of the Eiffel tower taken by Bob&quot;) </li></ul></ul><ul><ul><li>Administrative (e.g. &quot;taken on 19/04/2005&quot;) </li></ul></ul><ul><ul><li>Legal (e.g. &quot;all rights reserved&quot;) </li></ul></ul><ul><ul><li>Preservation (e.g. &quot;requirement to view as jpeg&quot;) </li></ul></ul><ul><ul><li>Technical (e.g. &quot;jpeg format&quot; ; &quot;85.8kb file&quot;) </li></ul></ul><ul><ul><li>Educational (e.g. &quot;an illustration of construction using cast iron&quot;; &quot;UK Education Level 11&quot;) </li></ul></ul><ul><ul><li>Structural (e.g. &quot;single file&quot;) </li></ul></ul><ul><ul><li>What of the above metadata is essential? </li></ul></ul><ul><ul><li>What of the above metadata is secondary (optional or removed)? </li></ul></ul>
    16. 24. Digital Asset Management : Implementation <ul><li>Who is the best agent to create each of these metadata elements? </li></ul><ul><li>What resources are available? </li></ul><ul><li>Do the available resource require compromises in the strategy or the metadata? </li></ul>
    17. 25. Digital Asset Management : Exercise <ul><li>Within FE what do you think could be generalised about: </li></ul><ul><ul><li>the purpose of a digital asset management strategies? </li></ul></ul><ul><ul><li>the asset types involved? </li></ul></ul><ul><ul><li>the key points of access? </li></ul></ul><ul><ul><li>the general context? </li></ul></ul>
    18. 26. Digital Asset Management : context <ul><li>Issues for digital asset management in FE (sample answers) </li></ul><ul><ul><li>Purpose of institution </li></ul></ul><ul><ul><ul><li>Teaching – strategy and system must support and not hinder teachers </li></ul></ul></ul><ul><ul><li>Resources available </li></ul></ul><ul><ul><ul><li>Limited - integration with existing practices vital; human overhead of using system must be minimal </li></ul></ul></ul><ul><ul><li>Use of materials </li></ul></ul><ul><ul><ul><li>Key points of access – tie into course, educational as well as bibliographic description </li></ul></ul></ul><ul><ul><li>Shelf-life of materials </li></ul></ul><ul><ul><ul><li>Course life; external determined typically < 3 years </li></ul></ul></ul><ul><ul><ul><li>Curation beyond this is in conflict with the purpose of the institution </li></ul></ul></ul><ul><ul><li>Ownership of materials </li></ul></ul><ul><ul><ul><li>Blanket policy – college’s property </li></ul></ul></ul>
    19. 27. Conclusions <ul><li>Skills and issues in construction and operation of systems for digital asset management are generally similar to library and information science skills needed for digital libraries </li></ul><ul><li>Digital asset management / digital library design – revolves around key questions of context, resources, and needs </li></ul>
