Parser and builder for XML Schema Definition (XSD) files.

Relaton is the database, registry, and cache for bibliographic references to technical standards in the Relaton/XML bibliographic model. It provides the Relaton::Db API, a registry that lazily loads each standards-body flavor (ISO, IETF, NIST, IEC, …) on first use, and a file-based cache. Every flavor ships inside this single gem — `gem install relaton` gives you the full multi-flavor setup, with flavor code loaded on demand via autoload. The CLI (relaton-cli) is a separate gem.

Cdd is a pure-Ruby library that models the IEC Common Data Dictionary (IEC 61360 / CDD ontology), supports power-type semantics where instances can themselves be used as classes, and imports the Parcel Excel workbook format (both ParcelMaker .xlsx and the legacy 6-file .xls export layout) into a navigable in-memory database.
