XFA (also known as XFA forms) stands for XML Forms Architecture, a family of proprietaryXML specifications that was suggested and developed by JetForm to enhance the processing of web forms. It can be also used in PDF files starting with the PDF 1.5 specification. The XFA specification is referenced as an external specification necessary for full application of the ISO 32000-1 specification (PDF 1.7). The XML Forms Architecture was not standardized as an ISO standard,[3] and has been deprecated in PDF 2.0.[4]
Overview[edit]
Free adobe livecycle download. Development Tools downloads - Adobe LiveCycle Data Services ES2 by Adobe Systems Incorporated and many more programs are available for instant and free download. LiveCycle Designer ES2 provides intuitive graphical design capabilities that make it easy to create and deploy templates without deep technical knowledge. With Adobe LiveCycle Designer ES2 software, development teams can work collaboratively, to create and preview templates, bind XML or ASCII data to back-end systems, and ensure that forms.
XFA's main extension to XML are computationally active tags. In addition, all instances created from a given XFA form template keep the specification of data capture, rendering, and manipulation rules from the original. Another major advantage of XFA is that its data format allows compatibility with other systems, and with changes to other technology, applications and technology standards.
According to JetForm's submission to the World Wide Web Consortium, 'XFA addresses the needs of organizations to securely capture, present, move, process, output and print information associated with electronic forms.'[5] The XFA proposal was submitted to the W3C in May 1999.
In 2002, the JetForm Corporation was acquired by Adobe Systems, and the latter introduced XFA forms with PDF 1.5 and the subsequent Acrobat releases (6 and 7) in 2003.[6]
XFA forms are saved internally in PDF files or as XDP (XML Data Package) files which can be opened in Adobe's LiveCycle Designer software. An XDP can package a PDF file, along with XML form and template data.[7] XDP provides a mechanism for packaging form components within a surrounding XML container.
Although XFA can make use of PDF, XFA is not tied to a particular page description language.
Adobe Livecycle Designer Help
The XFA specification includes an appendix that discusses details of the Adobe-specific XFA implementation and behaviors of Adobe products that deviate from the XFA specification.
Data filled in an XFA form may be submitted to a host using an HTTP POST operation in XDP format, PDF format, XFDF format, XML 1.0 format or as an URL-encoded format.
XFA supports the use of XSLT to transform the XML data before it is loaded to XFA Data DOM or after it is unloaded from XFA Data DOM.
One of XFA approaches to pagination duplicates the pagination logic and much of the syntax of XSL-FO.
XFA forms are synonymous with SmartForms in the Australian government.
Static and dynamic forms[edit]
XFA defines static forms (since XFA 2.0 and before) and dynamic forms (since XFA 2.1 or 2.2).
In a static form the form’s appearance and layout is fixed, regardless of the field content. Any unfilled fields are present in the form. By default, static forms does not require re-rendering. XFA recognises two types of static forms: 'old-style static forms' (using 'full XFA') and XFAF (a subset of full XFA, defined since XFA 2.5).
Dynamic forms (defined since XFA 2.1 or 2.2) can change in appearance in several ways in response to changes in the data. Dynamic form requires rendering of its content on file opening. Dynamic forms may also be designed to change structure to accommodate changes in the structure of the data supplied to the form. For example, a page of a form may be omitted if there is no data for it. Another example is a field that may occupy a variable amount of space on the page, resizing itself to efficiently hold its content. Dynamic form cannot rely on a PDF representation of its boilerplate, because the positioning and layout of the boilerplate change as the fields grow and shrink or as subforms are omitted and included.
Usage with Portable Document Format[edit]
PDF 1.7 supports two different methods for integrating data and PDF forms.[3][8]
- AcroForms (also known as Acrobat forms), introduced and included in the PDF 1.2 format specification.
- Adobe XML Forms Architecture (XFA) forms, introduced in the PDF 1.5 format specification as an optional feature (The XFA specification is not included in the PDF specification, it is only referenced.)
Adobe XFA Forms are not compatible with AcroForms. When an XFA is packaged inside a PDF file, it is placed in the AcroForm document resources dictionary ('Shell PDF') or referenced from the AcroForm entry in the document catalog.
Creating XFA Forms for use in Adobe Reader requires Adobe LiveCycle Designer.[9] Adobe Reader contains 'disabled features' for use of XFA Forms, that will activate only when opening a PDF document that was created using enabling technology available only from Adobe.[10][11] The XFA Forms are not compatible with Adobe Reader prior to version 6.
Profiles[edit]
Starting with XFA 2.5 forms can use a subset of the full XFA capability. Currently the only specified is the XFAF profile.
XFA can be used as:
- full XFA - which express all of the form, including boilerplate, directly in XFA (without any PDF or without a complete PDF background). It can be packaged inside a 'shell PDF' with minimal PDF markup or as a standalone XDP. It is used for dynamic XFA forms (since XFA 2.1) and also for so called 'traditional' (old-style) static XFA forms. Optionally it may include a pre-rendered depiction of the XFA form as PDF pages - but it is useful only for traditional static forms. Dynamic XFA must be rendered on file opening.
- XFAF (XFA Foreground) subset - (introduced in XFA 2.5) - a form in which each page of the XFA form overlays a PDF background. It can be used only for static XFA forms. This architecture uses only a subset of XFA.[12] It can be packaged inside a regular PDF document or as a standalone XDP file with embedded PDF. In XFAF each XFA field corresponds to a PDF interactive field (AcroForm field).
Packaging[edit]
XFA forms can be created and used as PDF 1.5 - 1.7 files or as XDP (XML Data Package). The format of an XFA resource in PDF is described by the XML Data Package Specification.[13] PDF may contain XFA in XDP format, but XFA may also contain PDF.[7]
When the XFA (XML Forms Architecture) grammars used for an XFA form are moved from one application to another, they must be packaged as an XML Data Package. The XDP may be a standalone document or it may in turn be carried inside a PDF document.[12]
XFA Form packaging variants (using XDP):
- as a standalone XML Data Package (XDP) (.xdp file) which can optionally also include a PDF file
- inside a regular PDF Document - used for static forms - XFAF.
- inside a 'Shell PDF' - used for the 'full XFA' form (dynamic or traditional static) - A Shell PDF file contains only a minimal skeleton of PDF markup plus the complete XFA content, any fonts and images needed for rendering of the form. It minimizes the file size and the rendering overhead is moved from the server to the client.
Packaging an XDP within PDF has the advantage that it is more compact, because PDF is compressed. XDP in PDF can be digitally signed in ways that a standalone XDP cannot.
In contrast, packaging form components within an XML container (XDP) makes it easy for standard XML applications to work with XFA forms. The XML components are human readable and easy editable (in contrast with PDF source code). When in XDP form, an XFA document may be validated using schemas attached to XFA specification.
Compatibility[edit]
Most PDF processors do not handle XFA content. When generating a shell PDF it is recommended to include in the PDF markup a simple one-page PDF image displaying a warning message (e.g. 'To view the full contents of this document, you need a later version of the PDF viewer.', 'The full content of this file cannot be displayed with your current PDF viewer.', 'Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document.', etc.). PDF processors that can render XFA content should either not display the supplied warning page image or replace it quickly with the dynamic form content.
In 2013, as a solution for mobile platforms and desktop platforms without XFA support, Adobe created software that creates online HTML5 fillable forms from XFA (known as Adobe 'Mobile Forms'). Mobile Forms are not a single file like a PDF or XDP.[14][15]
Rich text[edit]
Rich text may appear in data supplied to the XFA forms, in XFA templates as default text values, as field captions, or as boilerplate (draw) content.
Starting with PDF 1.5 (XFA 2.02), the text contents of variable text form fields, as well as markup annotations, may include formatting information (style information). These rich text strings are XML documents that conform to the rich text conventions specified for the XML Forms Architecture specification, which is itself a subset of the XHTML 1.0 specification, augmented with a restricted set of CSS2 style attributes.[13]
In PDF 1.6, PDF supports the rich text elements and attributes specified in the XML Forms Architecture (XFA) Specification, 2.2. In PDF 1.7, PDF supports the rich text elements and attributes specified in the XML Forms Architecture (XFA) Specification, 2.4.[13] It was announced in 2011 that PDF 2.0 (ISO 32000 Part 2) would reference XFA 3.1,[16] but when published, PDF 2.0 deprecated it.[4]
PDF/A[edit]
When an XFA form is converted to PDF/A, both the boilerplate and field content are flattened into a PDF appearance stream. PDF/A forbids active content and all XFA content except, optionally, the XML Data Document (forms data created by a user).
Standardization[edit]
The XML Forms Architecture specification is not included in the PDF 1.7 standard (ISO 32000-1:2008) and it is only referenced as an external proprietary specification created and published by Adobe. However, the ISO 32000-1 references XFA as normative and indispensable for the application of the ISO 32000-1 specification. XFA was not standardized as an ISO standard.
Since 2007, development of PDF standard has been conducted by ISO's Technical Committee 171/Subcommittee 2/Working Group 8 (TC 171/SC 2/WG 8).
In 2011 the ISO Committee urged Adobe Systems to submit the XFA Specification, XML Forms Architecture (XFA), to ISO for standardization, and requested that Adobe Systems stabilize the XFA specification. The Committee expressed its concerns about the stability of the XFA specification.[16]
In 2017 the ISO Committee deprecated XFA from PDF 2.0.[4]
