The Universal Basic Element Representation (UBER) Format

This document defines the Universal Basic Element Representation (ÜBER), a language-independent, lightweight, text-based serialization format designed for the portable representation, transmission, and storage of structured data. ÜBER employs a unified node architecture in which each node serves simultaneously as a value-carrier and a structural container. This recursive model allows any element to encapsulate a discrete data payload while concurrently functioning as a parent to nested members. The same structure also provides the granularity needed by implementations that target high-concurrency access patterns with localized, low-contention updates. A top-level ÜBER profile consists of either an explicit root object or a sequence of members and directives. To prioritize human-centric design and authoring ergonomics, the grammar supports comments, flexible arbitrary-length key-value separators, optional commas, and dotted member names. The ÜBER type system is defined by recursive containers and scalar forms. Associative arrays ({}) and collections ([]) support arbitrary nesting, while concrete ordering behavior remains implementation-dependent. Scalar forms include deterministic numbers with arbitrary-precision integer syntax and Java-aligned unsuffixed floating-point lexical forms, automatic magnitude-based fitting and promotion, versatile string representations including text blocks, flexible boolean literals, and both explicit and omitted null states. This specification defines the lexical and syntactic grammar of ÜBER. It does not define implementation-specific runtime facilities except where a grammar element, such as directives, requires a brief statement of purpose.
