10、zation for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establishe
11、d has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.T
12、he procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the
13、editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

17、 workflow.It is based on the soft-proofing ticket defined by the Ghent PDF Workgroup which uses XMP. This specification includes the specification of the Ghent PDF Workgroup soft-proofing ticket and extends it to include metadata required for the image preparation stage of the workflow.The intent of
18、 this metadata is to track who has approved the image or document, how the proof was prepared, and what the viewing conditions were during the approval. To achieve this, the approver is identified along with the document output conditions, the software used for the approval and details of the device
19、 configuration.

27、et to the image or document to which it refers.4.2 NamespaceThe namespace URI for XMP properties and fields defined in this International Standard shall be “http:/gwg.org/spt/xmlns/”.The preferred namespace prefix is spt.4.3 XMP packet structureAn XMP packet conforming to this International Standard
28、 shall include either the ImageApprovals property or the ProofingApprovals property but not both. An XMP packet conforming to this International Standard may contain other XMP properties.4.4 ImageApprovals propertyThe ImageApprovals property shall be a non-empty ordered array of ImageApproval record
29、s as specified in Table 1.The ImageApprovals record shall contain entries for all fields marked as Required and, where appropriate, should contain entries for those fields marked as Optional.NOTE There is currently no defined purpose to the ImageApprovals order. An ordered array is used for compatib
