# GTS

GTS, the Graph Transport Substrate, is a single-file, content-addressed,
append-only transport for RDF 1.2 graphs and the binaries those graphs
reference. A GTS file is a CBOR Sequence of segments: deterministic headers and
frames linked by BLAKE3 content identifiers, folded into a logical graph by a
deterministic replay model.

GTS is ontology-independent. It is the primary distribution method for GMEOW,
but a conformant reader does not need GMEOW vocabulary, OWL reasoning, or
agent-memory conventions to parse, verify, fold, or transport a GTS file.
