17、L STANDARD ISO 18565:2015(E)Document management AFP/Archive1 ScopeThis International Standard specifies the AFP document architecture by defining a subset appropriate for long-term preservation and retrieval.

ISO 2015 All rights reserved 1BS ISO 18565:2015ISO 18565:2015(E)4 Conformance4.1 GeneralThe MO:DCA architecture definition of compliance with the AFP/A interchange set is limited to what compliance means for MO:DCA print files, it does not in
25、clude definitions of AFP/A compliance for product compliance classes, e.g. generators and receivers. The architecture defines the content of AFP/A-compliant print files in terms of what is permitted (MAY), what is recommended (SHOULD), what is mandatory (SHALL), and what is prohibited (SHALL NOT).A
26、MO:DCA print file is compliant with the A FP/A interchange set definition if all the following conditions are met: all objects and their content shall be in AFP/A and shall comply with the AFP/A object structure definitions; all structured fields shall be in AFP/A and shall comply with the AFP/A par
27、ameter and triplet definitions; all structured field triplets shall be in AFP/A and shall comply with applicable AFP/A restrictions; all parameter values shall fall within the ranges defined by AFP/A; the print file shall not include any migration functions (as defined in the MO:DCA Reference, Appen
28、dix C) unless they are explicitly allowed in AFP/A (see Clause 9); the maximum structured field length shall be limited to X7FF0 = 32752; all Begin Document (BDT) structured fields shall specify the MO:DCA Interchange Set (X18) triplet with IStype = X05 (archive/presentation) and one of the followin
29、g: ISid = X0001 (AFP/A), or ISid = X0D01 (AFP/A, IS/3); the print file shall be enveloped with Begin Print File (BPF) and End Print File (EPF) structured fields and the BPF shall specify the MO:DCA Interchange Set (X18) triplet with IStype = X05 (archive/presentation), and one of the following: ISid
30、 = X0001 (AFP/A), or ISid = X0D01 (AFP/A, IS/3); in this case the same value shall be specified on the BDT for each document in the print file.4.2 Migration functionsIn general, AFP/A does not include any obsolete, retired, or coexistence MO:DCA parameters, triplets, structured fields, or objects as
31、 defined in MO:DCA Reference, Appendix C MO:DCA Migration Functions. For exceptions, see Clause 9.4.3 Structured field introducerThe Flag byte (byte 5) in the Structured Field Introducer (SFI) shall be set to X00. AFP/A does not include support for the following MO:DCA functions: SFI extension; Stru
32、ctured field segmentation; Structured field padding.2 ISO 2015 All rights reservedBS ISO 18565:2015ISO 18565:2015(E)The maximum structured field length in AFP/A is limited to X7FF0 = 32752.4.4 Exception conditionsIn general, no exception conditions are defined within the A FP/A definition for struct
33、ured fields or their parameters above and beyond what the general MO:DCA architecture defines. The following general rules apply.Exception conditions should not be generated solely due to non-compliance with AFP/A. When a valid print file is non-compliant with AFP/A, it should always be processed to
34、 the best of a receivers capabilities. That is, any object, object content, structured field, or structured field triplet that is valid in the general architecture but that is not included in the AFP/A definition, should be processed to the best of a receivers capability. For example, a receiver may
35、 generate an exception because it detected an error while processing an MCF-1 structured field, but not because the print file claimed to be AFP/A compliant and the MCF-1 structured field is not part of AFP/A.4.5 Restrictions to avoid device dependenceTo ensure that an AFP/A print file can be presen
36、ted accurately and consistently in the future, functions that are allowed in IS/3 but that are inherently device-dependent are not included in AFP/A. The IS/3 functions that shall not appear in AFP/A print files are the following: Device-dependent colours Use of the CMYK colour space (ColSpce = X04)
37、 in Color Specification Triplet and equivalent OCA structures, when not qualified with an audit Color Conversion CMR; Use of the Highlight Color Space (ColSpce = X06) in Color Specification Triplet and equivalent OCA structures, when not qualified with an Indexed CMR that specifies a substitute CIEL
38、ab value; Device-dependent fonts Use of the device default font in PTOCA text (local ID = XFF in SCFL control sequence); Use of the device default font in GOCA graphics (local ID = X00 or XFF in GSCS drawing order); BCOCA allows the use of a default font to print HRI, and since the HRI is not the ac
39、tual bar code, A FP/A allows the use of the default font for HRI. However, this may lead to a slightly different appearance when the archived file is re-printed. If it is mandatory that the HRI is reproduced the same way each time the AFP file is printed, the default font should not be used. Instead
40、, a TrueType/OpenType font that is carried in the print file resource group should be referenced and used; Images without clearly defined resolution AFPC JPEG and GIF images normally do not inherently specify their resolution. This resolution is needed to properly size the object for image presentat
41、ion space mapping options other than: the following: Scale to fit; Scale to fill.When a mapping option, other than these is specified, these images cannot be included in AFP/A print files unless they specify an Image Resolution (X9A) triplet. Device-dependent medium map functions the following MMC k
42、eywords: X90nn, X91nn: high/low media destination selector; XA0nn: fixed medium information; ISO 2015 All rights reserved 3BS ISO 18565:2015ISO 18565:2015(E) XA1nn: fixed perforation cut; XA2nn: fixed separation cut; XB4nn, XB5nn: high/low presentation subsystem set-up ID; XE0nn: media source select
43、or; XE1nn: media source ID; XF8nn: print quality control.In general, archiveability is improved by avoiding resolution dependent data since presentation device resolutions will change over time. For example, it is preferable to archive bar code data as a BCOCA object, which is resolution independent
44、, instead of as an image or a raster font.4.6 Page independenceIn AFP/A it is imperative that a single page can be retrieved from a document and viewed or printed exactly as it appears when printed within the context of the complete archived print file. This means that the last invoked medium map (t
45、he “active” medium map for the page) shall be known, and the numerical order of the page with respect to the last invoked medium map shall be known. As a result, the following triplets, which are optional in the general MO:DCA architecture and in IS/3, are mandatory on BPG structured fields in AFP/A
46、. FQN type X8D Begin Medium Map Reference. This triplet points to the last medium map that was invoked before the given page; that is it points to the active medium map for the page. Note that the referenced medium map may be an internal medium map, and this medium map takes precedence over a medium
47、 map in the print file resource group. Either the Medium Map Page Number (X56) triplet or the Page Position Information (X81) triplet. If both are specified the X81 triplet overrides. These triplets specify the sequence number of the page in the set of pages controlled by the active medium map.NOTE
48、The Presentation Control (X83) triplet remains optional on the BPG in AFP/A; if not specified, the page is both viewable and indexable.To ensure that colours are rendered properly, a page shall specify all CMRs and rendering intents required for presentation; the page cannot rely on inheriting these
49、 functions from higher levels in the document hierarchy.4.7 Availability of correct resourcesAll resources that are referenced within the AFP/A print file shall be carried in the print file resource group. AFP/A does not support referencing a resource that is stored in an external resource library. This ensures that the resource is available whenever the print file is processed and the same version of the resource is used whenever the pri
