Maps and rings form a dualistic view of the world. Maps are the public spatial view while rings are the private temporal view of the world. Maps are related to replacement and selection while rings are related to interrupts and reductions. Applications of maps indicate rings while entries into rings indicate maps. The irreversible temporal sequence of rings provide an ordering for maps. Maps and rings are both representations of multi- dimensional space, using spatial or temporal discontinuities to linearize information.

The map/ring dualism is shared by: name/meaning data/program hierarchical/sequential reversible/irreversible application/reduction entity/relationship taxon-information/ sequence-information operands/operators public/private visible/invisible external/internal spatial/temporal components/whole parallel/serial static/dynamic map/ring.

QuoteRef: cbb_1973 ;;11/3/73 Have sets and lists (control vectors). Are dual or complementary forms is one ordered info and other unordered info
QuoteRef: cbb_1973 ;;2/17/74 File's are timer related and maps are space oriented
QuoteRef: cbb_1973 ;;3/3/74 Both maps and files are ways to take a multi-dimension into one dimension i.e., maps for space and files for process
QuoteRef: cbb_1973 ;;5/27/74 A map gives an entry in a ring-- a holding point. eg, what is this persons name-- Fred i.e., name is an entry to this person
QuoteRef: cbb_1973 ;;5/27/74 The origin of a map is the name of a ring?
QuoteRef: cbb_1973 ;;11/24/74 Maps are sets of entries seen as parts, while rings (worms) are sets of entries seen as wholes
QuoteRef: cbb_1973 ;;11/24/74 Rings are internal forms while maps are external forms
QuoteRef: cbb_1973 ;;1/5/75 Can always see symbol as static (name) or active (value)
QuoteRef: cbb_1973 ;;6/24/75 Have both the structured and linear representation
QuoteRef: cbb_1973 ;;12/12/76 Operands are parallel sets while operators are a sequence
QuoteRef: cbb_1973 ;;12/12/76 Taking an object as parallel components or serial components is a matter of interpretation (map or ring)
QuoteRef: cbb_1973 ;;12/25/76 Maps are selectors while rings and applicators
QuoteRef: cbb_1973 ;;8/7/78 Each name has a static and a dynamic definition (ring/map) the dynamic definition is its value to some processor
QuoteRef: cbb_1973 ;;12/10/78 Purna separates application (the human side) from reduction (the machine side)
QuoteRef: cbb_1973 ;;3/13/74 file processor: follow links and handle interrupts, in the sense that the instructions themselves are handled automatically (are themselves files)
