  11                         A thing which represents a specific representation of an information resource: that conveyed by its <ref target="awol:body">body</ref> or by its <ref target="awol:src">source</ref>.

  14                         <ptr target="(AWOL)"/> remarks that this class encompasses things similar to “what one can get from a H·T·T·P connection”, in that it has a body as well as other associated metadata (provided by its other properties).
  15                         Providing a literal body, rather than a source, is strongly preferred.

  18                         The <ref target="awol:type">media type</ref> of the body may be provided, regardless of whether the body is provided literally or via a source.
  19                         However, there are restrictions on literal bodies :⁠—
