Instance Method Details

#build_datastream(datastream, force = false, is_required = false) ⇒ SomeDatastream

Builds that datastream using the content of a file if such a file exists and is newer than the object’s current datastream; otherwise, builds the datastream by calling build_fooMetadata_datastream.

Parameters:

  • datastream (String) —

    name of a datastream (e.g. “fooMetadata”)

  • force (Boolean) (defaults to: false) —

    overwrite existing datastream

  • is_required (Boolean) (defaults to: false)

Returns:

  • (SomeDatastream)

#create_workflow(name, create_ds = true, priority = 0) ⇒ Object

Initilizes workflow for the object in the workflow service

It will set the priorty of the new workflow to the current_priority if it is > 0
It will set lane_id from the item's APO default workflow lane

Parameters:

  • name (String) —

    of the workflow to be initialized

  • create_ds (Boolean) (defaults to: true) —

    create a ‘workflows’ datastream in Fedora for the object

  • priority (Integer) (defaults to: 0) —

    the workflow’s priority level
