TripleText
Convert from TripleTextto any other format
TripleText is a minimal, line-oriented plain-text notation for expressing typed graphs and knowledge bases as triples. It is the syntax behind the ddot.it project (see ddot.it) created by Calpano, the same author as the Connected JSON family, and is used by the graphinout.com toolchain as a human- and AI-friendly on-ramp for authoring connected data. Rather than defining its own document container, TripleText reduces a graph to a stream of subject–predicate–object statements written one per line, which a reader accumulates into a single in-memory knowledge base.
The core construct is the typed triple "aaa .. bbb.. ccc", where the doubled-dot delimiter separates a subject, a link/property type, and an object or literal value. When the relationship type is irrelevant, the shorthand "aaa .... ccc" expresses a simple, untyped link between two nodes. Consecutive lines that begin with ".." (for example "..bbb.. ccc") append further predicates to the most recently named subject, avoiding repetition. Optional per-statement metadata is attached after a double-comma "
