Zenodo ↗PTC
Protocol and specifications
The Canal Transparency Protocol (PTC) is published as an open corpus of six documents with distinct functions. Validator.es is a reference implementation; it is not the protocol.
Corpus map
The shared core combines with specialised profiles and formats. ARCH spans the whole set as the architectural framework. FRS-01 can be used directly or within Package Format 2.0; DCL-03 is an optional extension of the exact-file path.
Current corpus
Core
The three common pieces that define the protected object, the declaration and the protocol architecture.
PTC-F v1.2Core
Functional PTC specification
PTC fields, order, allowed values and the semantics of each declaration.

Zenodo ↗Published documents. All six specifications are published in ES/EN/FR with persistent DOIs. This page summarises their relationship; normative authority resides in the published documents.
Reference implementation
validator.es implements the current corpus. An independent implementation can be built from the published specifications without depending on this website or on El Canal.
