Singlemultiple

Singlemultiple is a term used in some discussions of data modeling and theoretical frameworks to describe a construct that can be interpreted as either a single element or as a collection of elements. It is not a standard term in mathematics or programming, but it appears in contexts that emphasize flexible representations and dual modes of access.

Definition and concept

A singlemultiple value can assume two complementary representations: a singular form (one value) and a plural form (a sequence or set of values). Systems that work with singlemultiples typically provide a unified interface that accepts either form and normalizes processing to a canonical internal representation, such as a list or array.

Examples

In data interchange formats like JSON, a field might accept a string or an array of strings. On the processing side, the value is normalized to a list for consistent handling. In some programming patterns, a parameter or return type may be designed to hold either a single item or multiple items, using a union type or a polymorphic interface to accommodate both forms.

Properties

Key properties include dual representation capabilities, an associated normalization step to unify internal processing, and support for both singleton and multi-valued inputs and outputs. Documentation often specifies the expected forms and any constraints on when one form is preferred over the other.

Applications and relation to other concepts

Singlemultiples are discussed in the context of data validation, API design, and flexible data models. They relate to broader ideas such as single-valued versus multi-valued functions, scalar and sequence types, and polymorphic interfaces. Because the term is informal and context-dependent, its exact meaning can vary between projects.
