Storage of metadata

Storage of metadata:

A) Internal:

  • Same file as the data
  • Transferred with the data at all times
  • High redundancy
  • Hard to aggregate metadata, e.g. have to parse the data file to get at the metadata

B) External:

  • Bundled with the file
  • Can be streamed before or after data capture
  • Makes for efficient searching and retrieval of data
  • Linked together using Uniform Resource Indentifiers (URIs)
  • Hard to ensure that these links are sane
