OpenCDD — Public Sample Data

Public sample data and tooling for OpenCDD, an open Common Data Dictionary online resource republishing IEC CDD data with additional models built on the same schema.

This repo holds the public, freely redistributable subset:

• OceanRunner sample dictionary (data/oceanrunner/) — a small marine-propulsion ontology used as a fixture and demo across the OpenCDD ecosystem.
• CDDAL spec (reference-docs/specs/cddal-v1.adoc) — the CDD Authoring Language plain-text format spec.
• OceanRunner source (reference-docs/examples/oceanrunner.cddal) — the CDDAL source the sample JSON is built from.
• Slim Rakefile + Gemfile for building the sample.

For the full IEC CDD dictionary data, see the sibling private repo opencdd/data-private (access restricted — IEC SC3D redistribution terms apply).

Quick start

bundle install
bundle exec rake browser:sample     # build data/oceanrunner/database.json from CDDAL

You'll need the opencdd Ruby gem installed. For local development across the opencdd org repos, the Gemfile uses a path dependency — clone opencdd-ruby as a sibling directory:
