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

This specification describes XFDF compatible with ISO 32000-2. XFDF is the XML version of Forms Data Format (FDF), a simplified versio

32、n of PDF for representing forms data and annotations.5.2 Forms data and annotationsForm fields in a PDF document may include many interactive elements (see ISO 32000-2:, 12.7). Figure 1 shows a sample PDF which utilizes edit boxes, buttons, and radio buttons:INTERNATIONAL STANDARD ISO 19444-1:2016(E

F

34、orm data are submitted to a server, modifications are made and sent back; the new form data are imported into the interactive PDF form. XFDF is also often used as a format to export form data to stand-alone files that can be stored, transmitted electronically, and imported back into the correspondin

36、, highlights, stamps and file attachments5.3 How to use this specificationThis specification documents the correspondence between an XFDF element or attribute and its equivalent PDF dictionary and key. A short description is provided for each element and attribute; for complete information, see the

37、description of the corresponding dictionary and key in ISO 32000-2. There are also a few attributes that do not correspond to a specific PDF dictionary and key.5.4 PDF, FDF and XFDF5.4.1 GeneralPDF, FDF, and XFDF are related specifications with PDF as the parent format for representing documents, in

38、cluding interactive forms and annotations. FDF and XFDF contain the subset of a PDF document that describes interactive forms and annotations. Complete information on PDF and FDF may be found in ISO 32000-2.FDF is a simplified version of PDF. PDF and FDF represent information with a key/value pair,

39、also referred to as an entry. This example shows the T and V keys with values enclosed in parentheses:/T (Street) /V (345 Park Ave.)XFDF, on the other hand, represents an entry with an XML element/content or attribute/value pair, as shown in the corresponding XFDF:345 Park Ave.XFDF implements a subs

40、et of FDF containing forms and annotations. There are XFDF equivalents for the Annots, Fields, F, and ID keys of the FDF dictionary. There are no XFDF equivalents for the other entries in the FDF dictionary such as the Status, Encoding, JavaScript, EmbeddedFDFs, Differences, Target, and Pages keys.X

41、FDF conforms to the XML standard (see W3C, Extensible Markup Language 1.0).In the simplest case, an XFDF element or attribute maps directly to a key in a particular dictionary of PDF. For example, the creationdate attribute is documented as corresponding to the CreationDate key ISO 2016 All rights r

42、eserved 3BS ISO 19444-1:2016ISO 19444-1:2016(E)in the markup annotation dictionary. This specification provides a description of the creationdate attribute, but more detailed information can be found in ISO 32000-2.An example creationdate attribute in XFDF:creationdate=”D:20030425095243-0700”An equi

43、valent entry in PDF or FDF would look like:/CreationDate (D:20030425095243-0700)In the example above, the underlying data stored within XFDF or PDF is identical. However, in other cases, the name and value differ. For example, the flags attribute corresponds to the F key in the annotation dictionary

44、. The value of the flags attribute is a comma separated list of the descriptive names of the flags, while the value of the F key is an integer with each bit representing a flag.This is the XFDF flags attribute:flags=”print,nozoom,norotate”This is the equivalent F entry in PDF or FDF:/F 28Finally, an

45、 element with multiple attributes can map to a single key with multiple values. The ids element in XFDF has attributes original and modified that map to the ID key in the FDF dictionary.Below is an example ids element in XFDF:This is the corresponding ID entry in FDF:/ID 4 ISO 2016 All rights reserv
