Content Caching

Definition

Content Caching

the content management task during which public content is cached

Classification

As illustrated in the preceding figure, Content Caching is part of the following inheritance hierarchy:

• Type: Concrete
• Superclass: Task
• Subclasses:
  • None

Responsibilities

The typical responsibilities of Content Caching are to:

• Decrease the access time of popular or recently requested content.

Preconditions

Content caching typically can begin when the following preconditions hold:

• The construction phase has started.
• The initial conventions for content caching (e.g., guidelines, standards) have been produced during the process engineering activity.
• The following documents are largely complete and are relatively stable:
  • System Requirements Specification
  • Information Architecture Document
  • Database Design Document
  • Human Interface Design Document
• The content management team has been adequately staffed and trained in content caching.
• A server or accellerator is available to store the cached content.

Completion Criteria

Content caching is typically complete when the following postconditions hold:

• The retirement phase has started.

Steps

Content caching typically involves the following teams performing the following steps in an iterative, incremental, parallel, and time-boxed manner:

• Content Management Team:
  • Determine the need for content transformation by reading and understanding the associated:
    • Informational (data) requirements in the:
      • System Requirements Specification
    • Information architecture:
      • Information Architecture Document
    • Content design:
      • Database Design Document
      • Human Interface Design Document
  • TBD

Techniques

Content caching typically can be performed using the following techniques:

• TBD

Work Products

Content caching typically results in the production of the following work products:

• data components:
  • Cached Content:
    • Textual content.
    • Numerical content.
    • Audio content.
    • Graphical content.
    • Video content.
  • Content Metadata

Guidelines

• Content caching should be performed iteratively, incrementally, and in parallel with other content management tasks.
• Content caching occurs on an as needed basis.
• Content caching is automated, typically by means of COTS products.
• The transformed content may be cached for future use.
• Content transformation may not be necessary content is only intended for a single client type.
