Concepts[edit]

See Item, Container Specs&APIs here

Container Handler[edit]

Containers offer the concept of aggregation, i.e. they can contain other (simple and complex) objects. Each container includes a structural map, which manages references to all members of the aggregation. Containers are versionable. They can be associated with a persistent identifier. Containers have a built-in basic object lifecycle. The status of a Container within its object lifecycle influences which actions are applicable and which user privileges are to be evaluated.

Item Handler[edit]

Items are objects representing the actual content of the repository. An item is a simple or complex object like an article, a report or a translation. Items are versionable. They can be associated with a persistent identifier. Items have a built-in basic object lifecycle. The status of an Item within its object lifecycle influences which actions are applicable and which user privileges are to be evaluated.

Premis Event Entity[edit]

The Event entity aggregates information about an action that involves one or more Object entities. Metadata about an Event would normally be recorded and stored separately from the digital object. Whether or not a preservation repository records an Event depends upon the importance of the event. Actions that modify objects should always be recorded. Other actions such as copying an object for backup purposes may be recorded in system logs or an audit trail but not necessarily in an Event entity. Mandatory semantic units are: eventIdentifier, eventType, and eventDateTime.

Hierarchical Listing of PREMIS Event Semantic Units,[edit]

This is a hierarchical listing of the semantic units included in the Data Dictionary. The information in parentheses following each semantic unit indicates whether the element is Mandatory (M), Optional (O) or Attribute (A) followed by whether it is Repeatable (R) or Not repeatable (NR).

V1.0[edit]

  1. eventIdentifier (M, NR)
    1. eventIdentifierType (M, NR)
    2. eventIdentifierValue (M, NR)
  2. eventType (M, NR)
  3. eventDateTime (M, NR)
  4. eventDetail (O, NR)
  5. eventOutcomeInformation (O, R)
    1. eventOutcome (O, NR)
    2. eventOutcomeDetail (O, R)
  6. linkingAgentIdentifier (O, R)
    1. linkingAgentIdentifierType (M, NR)
    2. linkingAgentIdentifierValue (M, NR)
    3. linkingAgentRole (O, R)
    4. linkingAgentXmlID (O, A)
  7. linkingObjectIdentifier (O, R)
    1. linkingObjectIdentifierType (M, NR)
    2. linkingObjectIdentifierValue (M, NR)
    3. linkingObjectXmlID (O, A)
  8. xmlID (M, A)

  4. eventDetail (O, NR)
  5. eventOutcomeInformation (O, R)
    1. eventOutcome (O, NR)
    2. eventOutcomeDetail (O, R)
      1. eventOutcomeDetailNote (O, NR)
      2. eventOutcomeDetailExtension (O, NR)
  6. linkingAgentIdentifier (O, R)
    1. linkingAgentIdentifierType (M, NR)
    2. linkingAgentIdentifierValue (M, NR)
    3. linkingAgentRole (O, R)
    4. LinkAgentXmlID (O, A)
  7. linkingObjectIdentifier (O, R)
    1. linkingObjectIdentifierType (M, NR)
    2. linkingObjectIdentifierValue (M, NR)
    3. linkingObjectRole (O, R)
    4. LinkObjectXmlID (O, A)
  8. xmlID (M, A)
