Micro Common Data Format Specification



Benjamin Long, John Dziurłaj


This specification describes a data format for space-constrained environments, such as the placement of machine readable data on paper. The specification is responsive to a need for interoperability in several key voting system scenarios in which the use of other storage mechanisms are impractical or disallowed. The format's structure is described in prose and code examples.
