PI Classification

The PI-Class^® method describes classification of modular content so that it can be created, managed and used in content management systems according to a logical concept.­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

At the very base of the PI-Class® method lies metadata that is separated into product-specific and information-specific criteria. Because of the way modular content is managed in content management systems further distinction between intrinsic and extrinsic categories is necessary. Variant management is also taken into account as it is a crucial factor in developing technical information products.­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

The logical concept according to PI-Class® is modelled through classification matrices and can be developed top-down (deductive) or bottom-up (inductive). It can also be applied to different information systems. PI-Class® is typically used in content management systems, content delivery portals, document management systems, product lifecycle systems and others.­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

The PI-Class® method is currently employed in numerous systems and implementations. As of May 2015 the method is registered as a trademark: PI-Class®. A basic introduction in the methodology can be found within the textbook Drewer/Ziegler "Technische Dokumentation" published by Vogel Business Media.
