  2. Having the Right Gear • Making the Right Decisions • Luck!

  3. Outline • The Importance of Metadata • Platforms • Databases: Pick Your Poison • A Brief Demonstration • Your New Best Friend • I Know This Much Is True

  4. The Importance of Metadata • Metadata: structured information about an object or collection of objects • No matter what access system you use, having the right metadata is essential • The services you want to offer will define the metadata you must capture • The storage format is not that important as long as you lose nothing and you can output it in all the ways you wish to support • Capturing it at the correct granularity is key

  5. Metadata Granularity • The degree to which you segment or “chop up” your metadata • Gross: <name>John Doe</name> • Fine: <name> <given>John</given> <family>Doe</family></name>

  6. Item v. Collection Metadata • Collection-level metadata: • Discovery metadata describes the collection • Example: Kentuckiana Digital Library; see www.kyvl.org/kentuckiana/digilibcoll/digilibcoll.shtml • Item-level metadata: • Discovery metadata describes the item • Example: MARC or Dublin Core records for each item; see californiadigitallibrary.org • Both types may be appropriate • Doing both often takes very little extra effort

  12. Databases: Pick Your Poison • Virtually any database or indexing product will in most cases work • Key considerations: • What do you already have (in-house or via a service provider)? • Which platform are you on? • Which product will your IT staff or service provider be willing to support? • What do you want your users to be able to do? • How much money do you have to spend?

  13. Databases: Examples • Targeted to the market and purpose; e.g., CONTENTdm from OCLC • General purpose commercial; e.g., Oracle, Sybase, SQL Server • General purpose open source; e.g., MySQL, SWISH-E • Shrink-wrapped consumer; e.g., MS Access, Filemaker Pro

  14. Database & Indexing Sofware • Sample Indexing Systems/Databases: • Sprite (Perl module) • Microsoft Access, Filemaker Pro • SWISH-E, swish-e.org • MySQL, mysql.com • ContentDM, OCLC • Oracle or Sybase Access/Filemaker Oracle, Sybase MySQL/ContentDM SWISH-E Sprite Less More The power & complexity continuum

  15. Two Brief Demonstrations… • SWISH-E Components: • A web server (Apache) and Perl • Free SWISH-E indexing software • An edited version of the included Perl script • Hand-created XML files (let’s do one!) • FileMaker Pro Components: • FileMaker Pro • Web Access Plug-in enabled

  16. Your New Best Friend • Your System Administrator/Service Provider will be very important to you • Definition: The one person or organization upon whom the success of your project rests (i.e., God); and, the one person or organization who can most easily damage your project (i.e., the Devil) • Foster good relations • Communicate your needs clearly, and listen well

  17. I Know This Much is True • Never forget for whom you are doing this! • Neither an early adopter nor latecomer be • Never underestimate the power of a prototype • Back it up or kiss it goodbye • Computers are cheap, people are expensive • Storage is cheaper than dirt • Buy hardware at the last possible moment

  18. I Know This Much is True • Don’t buy software with a zero at the end of the release number • Like love and money, you can never have too much RAM, disk space, or CPU speed • All things being equal, open is better than proprietary • Know your source of support going in

  19. I Know This Much is True • For any given project, there are many waysit can succeed • Just focus on (you guessed it): 1) having the right gear, and 2) making the right decisions ( and coming here was a great start)

  20. Final Advice • Start and end with your users and the services you wish to provide • Digitize at the highest quality that you can, and save an unprocessed copy • Capture as much metadata as you can stand and store it in a highly granular fashion • Have fun!
