  1. Metadata and XML <xmlpresentation> <conference type="name">Museum Computer Network</conference> <conference type="location">Las Vegas</conference> <conference type="date">Nov 07, 2003</conference> </xmlpresentation> MCN Nov 7, 2003

  2. Was it easier? 15 – 20 years ago: You had an object, or book you wanted to describe. Now you have: Object Record of object in catalog Record of digital object in catalog Digital Object Digital Master Descriptive Metadata Preservation Metadata Administrative Metadata Access File Descriptive Metadata MCN Nov 7, 2003

  3. Technology Helps? • The description of digital objects has become more difficult as technology allows people to expect more information about an item. MCN Nov 7, 2003

  4. What does this mean for us? • Library Catalog • Catalog for digital collections • Special databases for specific collections. • Websites designed for collections as they are digitized • Greater demand for technological advancement. MCN Nov 7, 2003

  5. What do we do? • Combine as many processes as we can. • Streamline as much metadata collection as possible. MCN Nov 7, 2003

  6. What is XML • Extensible Markup Language • Allows for customization • A language of Rules, Rules, Rules • A language that is designed to be parsed • Therefore allowing for the data to be moved around easily from one system to another MCN Nov 7, 2003

  7. What will it do for us? Replace our metadata element sets? No… It will help us store our metadata MCN Nov 7, 2003

  8. How will it do this? Enter the flat-file database Again… “Haven’t I heard of that type of database before?” MCN Nov 7, 2003

  9. What UNT did • UNT Digital Projects Department • Developed the UNTL metadata element set • Developed with IndexData a schema for representing our metadata set in a structured data format independent of a relational database • Tailored a toolkit designed by IndexData to meet our needs, (user interface, ADA requirements, forward thinking, cost effectiveness MCN Nov 7, 2003

  10. What did we get • A system that allows for the storage of metadata from a wide variety of areas in our library. • A system that allows us to tailor the outputs of our metadata files, and related digital objects into a format the is both informative and technologically timely. • A system that is robust, and is designed to change to meet the needs of our libraries digital collections. MCN Nov 7, 2003

  11. And example of an object Rare book, Author, Binder, Location, Dates, Printer, Location, Dates of printer Illustrator Printer of the book plates Who owned the book, Preservation metadata for all items in the system Administrative metadata for all items in the system Descriptive metadata for all items in the system MCN Nov 7, 2003

  12. Does it play well with others? • Open source • XML based so the records can be transformed with XSLT into just about anything • Z39.50 compatible • Able to export to MARC, DC, or a traditional library catalog, or relational database. MCN Nov 7, 2003

  13. Future Grand Dreams • A system that allows for all information about an object to be stored in the same place. • A system that is DC based, and is MARC based, and is able to be searched by Z39.50, and can hold everything in one record and can display everything at once, or limit what is displayed. • A system that is easy to use, and the information needs to be able to be moved to and from the system in a variety of ways, and it has to be scalable, and it has to be ... MCN Nov 7, 2003

  14. We have the technology… • XML flat-file systems can do this!! MCN Nov 7, 2003

  15. The End. Thank you.. Mark Phillips Digital Projects Lab Manager Digital Projects Department University of North Texas MCN Nov 7, 2003
