What is QIF?
QIF (Quality Information Framework) is an American National Standard supporting Digital Thread concepts in engineering applications ranging from product design through manufacturing to quality inspection. Based on the XML Standard, it contains a Library of XML Schema ensuring both data integrity and data interoperability in Model Based Enterprise implementation.
QIF supports Design, Metrology, Manufacturing, and is critical to the Industrial Revolution 4.0. Because it is XML based, QIF can be easily integrated with Web/Internet applications and unlike other existing standards, there is no competence barrier standing in the way for industry to adopt QIF. It also effectively supports new concepts such as IoT (Internet of Things).
Finally, all discrete manufacturing industries now have a standard platform that ensures quality while minimizing costs and making processes more transparent! The QIF 2.1 Standard is available at no cost via download.
QIF is an integrated set of XML schema based standards enabling the seamless flow of information within computer-aided quality measurement systems.
All information models for transporting quality data are derived from common model libraries so that common information modeling components can be reused throughout the entire quality measurement process. As a consequence, the entire process is inherently interoperable.
ANSI QIF is made up of 8 parts:
Part 1: QIF Overview – Description of the general content and structure of the entire QIF information model, including the highest level data structures.
Part 2: QIF Library – Core QIF data structures used throughout different QIF application areas.
Part 3: QIF MBD – Or Model-Based Definition, QIF MBD defines a digital data format to convey part geometry (typically called the “CAD” model) and information to be consumed by downstream manufacturing quality processes, such as PMI.
Part 4: QIF Plans – Defines the digital format to convey measurement plans, which could include a set of features and characteristics to be measured, resources to be used, measurement procedure to be used, etc.
Part 5: QIF Resources – Digital definition of dimensional measurement resources, sufficient for use in generating a high level measurement plan for product certification, acceptance, or any other common application of dimensional measurement data.
Part 6: QIF Rules – Defines for format for specifying measurement rules, which are also sometimes referred to as measurement templates or measurement macros.
Part 7: QIF Results – Defines the format for specifying results of quality operations.
Part 8: QIF Statistics – Used to define statistical analysis of a set of results (e.g., individuals, averages, standard deviations, max, min, etc.)

The QIF Community Hub
Head on over to our GitHub page to join the QIF Community. Here you will find free tools for using QIF data, an “Issues” list for submitting QIF enhancement requests or asking general questions, and a wiki with good information about QIF and the QIF Community.
Where To Submit Standard Improvement Requests
Special Note: If you or your organization discover a problem with any DMSC Standard — either DMIS or QIF — OR if you wish to suggest an improvement, you may submit your issue on the qif-community Issues list. See this page here for instructions on how to submit a topic.
