SLIS 5715.002

Week 7


 

next week: discuss readings; lab time

 

need to be working on first 20 images:

  • standard size / resolution
  • metadata
  • anecdotes
  • also be thinking about the relation / family tree
  • include rights statement about permission

 

Metadata Readings

(discussed RLG two articles)

(discussed reference readings)

 

Metadata and Images (Elise Lewis, ppt)

Basics

  • need metadata in order to find items (access)
  • helps to organize a collection
  • managers, users, and objects themselves (preservation) need metadata
  • must be cost-effective (find a balance)
  • interoperability enables a collection to interact with other collections
  • automated vs. human interaction

 

Types of Metadata

  • structural
  • descriptive
  • administrative
    • technical
    • preservation
    • rights

 

Structural Metadata

  • compound objects (relation of objects to each other)
  • thumbnail, web copy, archival copy = 1 object
  • artist's statement, image = 1 object

 

Descriptive Metadata

  • most used by user
  • thesauri / controlled vocabulary
    • consistency is important
  • content (physical description) vs. concept (abstract part)
    • content: woman holding a cloth with a face on it; concept: St. Veronica
    • is-ness vs. about-ness
  • content-based image retrieval (my paper on the topic)

 

Administrative Metadata

  • manage resources
  • unique aspects to images
  • technical
    • camera model
    • settings
    • has it been retouched
    • lighting
  • preservation
    • original condition (of analog item)
    • version
    • file format
    • software used
  • rights
    • intellectual rights
      • copyright
      • permissions information

 

Schema

  • some elements are very specific; some are broad
  • maintain interoperability
  • defines the important elements (required)
  • image-specific
  • syntactical rules

 

Dublin Core

  • cross-disciplinary
  • from Library of Congress
  • works fine with images
  • is expandable and repeatable

 

Image Metadata Schema

  • VRA Core
    • used for art and museum images
    • style/period
    • materials
    • culture
  • CDWA
    • condition
    • provenance (for museums)
    • orientation (?)

 

Interactive Image Metadata

  • METS
    • acts as a wrapper
    • allows executables
  • MODS
  • MPEG Multimedia Metadata Standard
    • system tools
    • audio/video

 

Discussion

  • what is your record level?
    • example: DC Creator
      • item-level (digital) or object-level (analog)
      • image of a house; is the DC Creator:
        • creator of the physical house?
        • creator of the analog image?
        • creator of the digital image?

 

About Metadata Report

  • looking for similar doc. to DC Metadata Element Set (not that detailed)
  • particularly section #5 element name, label, definition
  • tailored to your collection
  • specify which are repeatable
    • (I might want to include some kind of statement about name authority / controlled vocabulary / input rules, etc.)

 

The Breakdown

  • class/type
    • administrative
    • preservation
    • descriptive
    • structural
  • schemes
    • DC
    • VRA
    • METS
  • elements
    • creator
    • date
    • language

 

Discussion About Elements

  • title
    • naming convention
  • creator
    • (specifically, could be author, artist, photographer, composer)
    • add qualifiers: digital creator, photographer, artist, etc. (in the case of digital photography...?)
  • subject
    • (aboutness)
    • need to decide thesaurus / controlled vocabulary (look for genealogical / archival)
  • type
    • (materials)
  • format
    • digital file format
  • genre
  • description
  • contributor
  • language
    • language of song
