AS ISO 19005.3:2017 Document management – Electronic document file format for long- term preservation
6.5.1 General
TheLaunch,Sound,Movie,ResetForm,ImportData,Hide,SetOCGState,Rendition, Trans,GoTo3DView and JavaScript actions shall not be permitted. Additionally, the deprecated set-state and no-op actions shall not be permitted. Named actions other than NextPage, PrevPage, FirstPage, and LastPage shall not be permitted. In response to each of the four allowed named actions, conforming interactive readers shall perform the appropriate action described in ISO 32000-1:2008, 12.6.4.11, Table 211.
NOTE 1 Support for multimedia content is outside the scope of this part of ISO 19005. The ResetForm action changes the rendered appearance of a form. The ImportData action imports form data from an external file.
Hide actions set an annotation’s Hidden flag. JavaScript actions permit an arbitrary executable code that has the potential to interfere with reliable and predictable rendering.
NOTE 2 Additional requirements for interactive form fields are specified in 6.4.
6.5.2 Trigger events
A Widget annotation dictionary or Field dictionary shall not include an AA entry for an additional-actions dictionary. The document’s Catalog shall not include an AA entry for an additional-actions dictionary.
The Page dictionary shall not include an AA entry for an additional-actions dictionary.
NOTE These additional-actions dictionaries define arbitrary actions such as JavaScript. The explicit prohibition of the AA entry has the implicit effect of disallowing actions that can create external dependencies and complicate preservation efforts.
6.5.3 Handling of GoToR, GoToE, URI and SubmitForm actions
While permitted to be present in a conforming file, there are four types of actions for which a conforming interactive reader shall provide special treatment: the GoToR, GoToE, URI and SubmitForm actions. The conforming interactive reader shall provide a mechanism to display the F and D keys ofa GoToR or GoToE action dictionary, the URI key of a URI action dictionary, and the F key of a SubmitForm action dictionary. In addition, since the actual invocation of these four actions by a conforming interactive reader involves the locating of and interacting with other files that may or may not be conforming, the reader may choose to not allow the actual invocation of these actions.
NOTE For purposes of archival disclosure of the complete information content of conforming files, it is important for interactive readers to provide some mechanism to expose the destination of such actions. However,this part of ISO 19005 does not prescribe any specific behaviour or the technical implementation details that interactive readers might use to meet these functional requirements.
