Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991.
A de facto standard is a custom or convention that has achieved a dominant position by public acceptance or market forces. De facto is a Latin phrase, here meaning "in practice but not necessarily ordained by law" or "in practice or actuality, but not officially established".
Adobe Acrobat is a family of application software and Web services developed by Adobe Inc. to view, create, manipulate, print and manage Portable Document Format (PDF) files.
XFA stands for XML Forms Architecture, a family of proprietary XML 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. The XML Forms Architecture was not standardized as an ISO standard, and has been deprecated in PDF 2.0.
COLLADA is an interchange file format for interactive 3D applications. It is managed by the nonprofit technology consortium, the Khronos Group, and has been adopted by ISO as a publicly available specification, ISO/PAS 17506.
The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets.
Product and manufacturing information, also abbreviated PMI, conveys non-geometric attributes in 3D computer-aided design (CAD) and Collaborative Product Development systems necessary for manufacturing product components and assemblies. PMI may include geometric dimensions and tolerances, 3D annotation (text) and dimensions, surface finish, and material specifications. PMI is used in conjunction with the 3D model within model-based definition to allow for the elimination of 2D drawings for data set utilization.
Universal 3D (U3D) is a compressed file format standard for 3D computer graphics data.
Open XML Paper Specification is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). In June 2009, Ecma International adopted it as international standard ECMA-388.
JT is an openly-published ISO-standardized 3D CAD data exchange format used for product visualization, collaboration, digital mockups, and other purposes. It was developed by Siemens.
Rhinoceros is a commercial 3D computer graphics and computer-aided design (CAD) application software that was developed by Robert McNeel & Associates, an American, privately held, and employee-owned company that was founded in 1969. Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics.
An IFilter is a plugin that allows Microsoft's search engines to index various file formats so that they become searchable. Without an appropriate IFilter, contents of a file cannot be parsed and indexed by the search engine.
PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents. PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking and encryption. The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations.
GeoPDF refers to map and imagery products created by TerraGo software applications. GeoPDF products use geospatial PDF as a container for maps, imagery, and other data used to deliver an enhanced user experience in TerraGo applications. However, GeoPDF products conform to published specifications including both the OGC best practice for PDF georegistration as well as Adobe's proposed geospatial extensions to ISO 32000, making them readable by applications such as Adobe Acrobat, Adobe Reader, Avenza PDF Maps, Global Mapper, and others. GeoPDF products often include other advanced PDF features such as layers and object data which can add significant GIS functionality to the file, particularly when used with the TerraGo Technologies plugin to Adobe Reader or other TerraGo clients.
Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.
PostScript fonts are font files encoded in outline font specifications developed by Adobe Systems for professional digital typesetting. This system uses PostScript file format to encode font information.
Cogniview is an international computer software company, focusing mainly on data conversion applications for the PC.
Datalogics is a computer software company formed in 1967 and based in Chicago, IL. The company licenses software development kits for working with PDF and other document file types. They have previously developed their own typesetting and database publishing software. Since 1996, Datalogics has also acted as a channel for several SDKs from Adobe Systems. These include the Adobe PDF Library, Adobe Experience Reader Extensions, Adobe Content Server, Adobe InDesign Server, Adobe PDF Converter, Adobe PDF Print Engine and Adobe Reader Mobile SDK. In 2022, Datalogics launched a new business unit called pdfRest, an API toolkit for PDF processing.
