Recursive-LD Releases

Version history, structural evolution, and forward development plans.

Overview

This page documents all published and planned versions of the Recursive-LD standard. Versioning follows the rule: v1.x for backwards-compatible refinements, v2.0+ for structural changes that may break compatibility.

Published Versions

Recursive-LD v1.0 — Initial Release

Date: 2025-11-15

The foundational edition of Recursive-LD, establishing the core vocabulary for cognitive traces, recursive steps, epistemic lineage, and interpretability metadata. This release defines the canonical context and sets the baseline for conformance.

Introduced CognitiveTrace type
Introduced RecursiveStep type
Defined minimal linear recursion model
Established v1.0 JSON-LD context namespace
Specified required fields and conformance rules
Published primer, examples, and governance structure

Planned Versions

Recursive-LD v1.1 — Expanded Metadata (Planned)

Status: Under discussion

A backwards-compatible refinement focusing on enhancing interpretability metadata and recursive diagnostic fields.

Refined uncertainty and drift fields
Optional ReasoningSummary property
Expanded Lineage provenance structure
Typed recursion reference categories

Recursive-LD v2.0 — Structural Recursion Upgrade (Planned)

Status: Future development

The first major revision to the standard, introducing structural changes and expanded expressiveness beyond v1.x constraints.

Branching recursion structures
Multi-agent recursive reference support
Long-horizon reasoning representation
Probabilistic reasoning fields
Security-grade audit trace encoding

Versioning Policy

Recursive-LD uses the following versioning scheme:

Major versions (v2.0+): Structural or semantic changes
Minor versions (v1.x): Backwards-compatible additions
Patches (v1.0.x): Documentation and example corrections only

Release Notes Access

As new versions are published, detailed release notes will appear on this page. Early-stage versions may include supporting research, prototype data, and cross-standard references from the RAI Observatory.
