1 Besser--JISC Image Metadata 6/20/02 1 Image Metadata: Important Recent Activities Howard Besser UCLA School of Education & Information

2 Besser--JISC Image Metadata 6/20/02 2 Image Metadata -  Models for Digital Libraries  Importance of Metadata Standards & Philosophies  Discovery Metadata: The Dublin Core  Administrative and Structural Metadata: MOA2/METS  Actors Metadata  Longevity Metadata  Identification/Provenance  The 4/99 NISO/DLF Image Metadata Workshop  Various other Metadata

3 Besser--JISC Image Metadata 6/20/02 3 Key problems we’re facing  Discovery  Longevity-  Interoperability-

4 Besser--JISC Image Metadata 6/20/02 4 Serious Longevity Problems  What we know from prior widespread digital file formats  Images separating from their metadata  Inaccessibility of software needed to view an image  Inability to even decode the file format of an image

5 Besser--JISC Image Metadata 6/20/02 5 Traditional Digital Library Model DL user search & presentation

6 Besser--JISC Image Metadata 6/20/02 6 Ideal Digital Library Model DL user search & presentation

7 Besser--JISC Image Metadata 6/20/02 7 For Interoperability Digital Libraries Need Standards  Descriptive Metadata for consistent description  Discovery Metadata for finding  Administrative Metadata for viewing and maintaining  Structural Metadata for navigation ... Terms & Conditions Metadata for controlling access...

8 Besser--JISC Image Metadata 6/20/02 8 Why are Standards and Metadata consensus important?  Managing digital files over time  Longevity  Interoperability  Veracity  Recording in a consistent manner  Will give vendors incentive to create applications that support this

9 Besser--JISC Image Metadata 6/20/02 9 Philosophical Metadata Decisions- _ Warwick vs MARC _ Where to put the metadata

10 Besser--JISC Image Metadata 6/20/02 10 Containers and Packages of Metadata Warwick, not MARC _ modular _ overlapping _ extensible _ community-based _ designed for a networked world to aid commonality btwn communities while still providing full functionality within each community

11 Besser--JISC Image Metadata 6/20/02 11 Some different schemes where Metdata is kept _ embedded withing the object (HTML tags) _ in a separate related DB maintained by same organization (OPAC, MOA II) _ in a separate DB maintained by a separate organization (Books in Print, ratings systems) _ derived on-the-fly from a different scheme (MARC-to-DC)

12 Besser--JISC Image Metadata 6/20/02 12 Discovery Metadata _ Dublin Core - NISO Z39.85 (3/95)- _ CBIR (ongoing)

13 Besser--JISC Image Metadata 6/20/02 13 Dublin Core--further work _ Warwick Framework – metadata packages for extensible functions – layed groundwork for RDF _ Canberra Qualifiers – refining the semantics of the element set to provide more precise info – SUBELEMENT, SCHEME, LANG _ Granularity – no hierarchical relationships w/i a given DC record; only one record per discrete object (collection or item-level), and relationship field plus qualifier links them

14 The Research Process and Functional Categories of Metadata _ Discovery _ Retrieval _ Collation _ Analysis _ Re-presentation

15 Besser--JISC Image Metadata 6/20/02 15 Structural & Administrative Metadata-  Making of America II (MOA2)  Metadata Encoding & Transmission Standard (METS)

16 Besser--JISC Image Metadata 6/20/02 16 MOA II Classes of Objects  Continuous Tone Photos  Photo Albums  Diaries, journals, letterpress books  Ledgers  Correspondence

17 Besser--JISC Image Metadata 6/20/02 17 MOA II Metadata _ Administrative Metadata – for enhancing resource management _ Structural Metadata – for reflecting internal hierarchies and relationships btwn parts _ Raw/Seared/Cooked

18 Besser--JISC Image Metadata 6/20/02 18 MOA II Behaviors  Navigation  Display/Print

19 Besser--JISC Image Metadata 6/20/02 19 MOA II Best practices  Use/Users/Collection:  Benchmarking  Masters vs. Derivatives  Scanning-  Administrative Metadata-  Structural Metadata-

20 Besser--JISC Image Metadata 6/20/02 20 Scanning Best Practices _ Think about users (and potential users), uses, and type of material/collection _ Scan at the highest quality that does not exceed the likely potential users/uses/material _ Do not let today’s delivery limitations influence your scanning file sizes; understand the difference between digital masters and derivative files used for delivery _ Many documents which appear to be bitonal actually are better represented with greyscale scans _ Include color bar and ruler in the scan _ Use objective measurements to determine scanner settings (do NOT attempt to make the image good on your particular monitor or use image processing to color correct) _ Don’t use lossy compression _ Store in a common (standardized) file format _ Capture as much metadata as is reasonably possiple (including metadata about the scanning process itself)

21 Besser--JISC Image Metadata 6/20/02 21 Why Scale is important

22 Besser--JISC Image Metadata 6/20/02 22 Administrative Metadata to uniquely identify a digital resource and manage it over time _ Information about where the various pieces/versions of the object reside _ Information to view the digital object _ Information about the scanning process

23 Besser--JISC Image Metadata 6/20/02 23 Structural Metadata: that which is relevant to presentation of the digital object to the user _ metadata defining the "object”: a book, a diary, a photo album _ metadata defining the “sub-objects”: pages (physical) or chapters and subheads (intellectual)

24 Besser--JISC Image Metadata 6/20/02 24 Other Types of Metadata- _ Actors Metadata _ Longevity _ Identification/Provenance _ Rights Management

25 Besser--JISC Image Metadata 6/20/02 25 Reference Models for Digital Libraries: Actors and Roles DELOS/NSF Working Group
