Module: RDF::Util::File

Defined in:
lib/rdf/util/file.rb

Overview

Wrapper for Kernel.open. Allows implementations to override to get more suffisticated behavior for HTTP resources (e.g., Accept header).

Also supports the file: scheme for access to local files.

Classes include this module when they represent some form of a file as a base resource, for instance an HTTP resource representing the serialization of a Graph.

This module may be monkey-patched to allow for more options and interfaces.
