CALS (Engl. Computer-Aided Acquisition and Life Cycle Support , computerized procurement and life cycle -support ) is the name for a global strategy and business together to conversion extensive technical since the 1980s documentation from paper to electronic documents. CALS was originally developed by the US Department of Defense in order to implement uniform exchange formats (such as SGML , CGM and IGES ), especially in the military and armaments sectors. In addition, own standards have been defined, such as the CALS table model , which is used by DocBook , EAD and TEI , among others .

The focus and direction of the CALS strategy have expanded over time. Originally started as Computer-Aided Logistics Support (English for computer-aided logistics support ), it changed to Computer-Aided Acquisition and Logistics Support (computer-aided procurement and logistics support) . At present (2006), the CALS strategy is understood to be the electronic storage and transmission of all relevant information relating to a product during its entire life cycle (from planning and development through production to operation and finally to disposal) the usual description of the acronym today .

CALS raster graphics file format

The CALS raster graphics file format is a standard for the exchange of graphic data. It saves images in monochrome mode (black and white). The typical filename extensions are DCL and RAS. Its development took place within the CALS-DOD initiative, the format defines standards for coding and compression of raster graphics (monochrome bitmap). References: MIL-R-28002; MIL-PRF-28002.

CALS table model

The CALS table model is a standard for representing tables in SGML / XML format. Its development took place within the CALS-DOD initiative, the format is based on the inexhaustible descriptions and examples of the Mil-M-38784B specification for technical manuals. During the realization and technical implementation, inadequacies became apparent, so that a successor specification by the Organization for the Advancement of Structured Information Standards (OASIS) became necessary.
