Method: OcflTools::OcflValidator#verify_directory

Defined in:

lib/ocfl_tools/ocfl_validator.rb

#verify_directory(version) ⇒ OcflTools::OcflResults

We may also want to only verify a specific directory, not the entire object. For example, if we’ve just added a new version, we might want to just check those files and not the rest of the object (esp. if it has some very large version directories).

Parameters:

• version (Integer) —

  directory to verify

Returns:

• (OcflTools::OcflResults) —

  of verify events

  # start by getting version format and directories.

  # OK, now we need an inventory.json to tell use what the contentDirectory should be.

  # Now generate checksums for the files we found on disk, and Hash them.

  # Finally! Pass them to checksum checker.
