• Simple, easy to implement and understand other
  uses are being layered on top (e.g., dynamic
  searching)
• CDL is creating tools to enable campus librarians

• Functional Requirements for Bibliographic Records
  (from IFLA)
• A conceptual framework
• Work (Hamlet Prince of Denmark)
• Expression (a Russian translation)
• Manifestation (third printing)

• Records for manifestions (presently separate)
  can be collapsed into one item at the work or
  expression level

47
XML

• A simple and yet powerful way to encode
  information in a structured format for processing
  and communication
• All kinds of hot new services use it, from
  OAI-PMH to RSS and SRU/SRW even library catalog
  systems
• The single most important technology for
  libraries since the Internet!

48
Making Good Technology Decisions

• Keep an ear to the ground and an eye on the
  horizon
• Hold new technologies up to the light of your
  mission and priorities
• Watch out for 800 lb. Gorillas
• Dont ignore an upstart with a compelling product

49
Making Good Technology Decisions

• Dont bet the farm on things you cant control
• All things being equal, open is better than
  proprietary
• Technology with market share often prevents or
  kills better technology
• Howevermarket share is not everything
• Get good advice
• Know your source of support

50
I Know This Much is True

• Neither an early adopter nor latecomer be
• Its the user, stupid!
• Dont expect users to know what they want until
  they see it
• Never underestimate the power of a prototype
• Back it up or kiss it goodbye

51
I Know This Much is True

• Buy hardware at the last possible moment
• Dont buy software with a zero at the end of the
  release number
• Never let anyone prevent you from providing a
  service because of a lack of storage space disk
  space is cheaper than dirt!
• If you cant be with the operating system you
  love, love the one youre with
