Instance Method Details

#allows_modification? ⇒ Boolean

Returns true if the object is in a state that allows it to be modified. States that will allow modification are: has not been submitted for accessioning, has an open version or has sdr-ingest set to hold.

Returns:

  • (Boolean) —

    true if the object is in a state that allows it to be modified. States that will allow modification are: has not been submitted for accessioning, has an open version or has sdr-ingest set to hold

#close_version(opts = {}) ⇒ Object Also known as: submit_version

Sets versioningWF:submit-version to completed and initiates accessionWF for the object

Parameters:

  • opts (Hash) (defaults to: {}) —

    optional params

Options Hash (opts):

  • :description (String) —

    describes the version change

  • :significance (Symbol) —

    which part of the version tag to increment :major, :minor, :admin (see Dor::VersionTag#increment)

  • :version_num (String) —

    version number to archive rows with. Otherwise, current version is used

  • :start_accesion (Boolean) —

    set to true if you want accessioning to start (default), false otherwise

Raises:

  • (Dor::Exception) —

    if the object hasn’t been opened for versioning, or if accessionWF has already been instantiated or the current version is missing a tag or description

#open_new_version(opts = {}) ⇒ Object Also known as: start_version

Increments the version number and initializes versioningWF for the object

Parameters:

  • opts (Hash) (defaults to: {}) —

    optional params

Options Hash (opts):

  • :assume_accessioned (Boolean) —

    If true, does not check whether object has been accessioned.

  • :create_workflows_ds (Boolean) —

    If false, initialize_workflow() will not initialize the workflows datastream.

  • :vers_md_upd_info (Hash) —

    If present, used to add to the events datastream and set the desc and significance on the versionMetadata datastream

Raises:

  • (Dor::Exception) —

    if the object hasn’t been accessioned, or if a version is already opened
