Expressir: EXPRESS in Ruby

Gem Version Build Status

Purpose

Expressir (“EXPRESS in Ruby”) is a Ruby parser for EXPRESS and a set of Ruby tools for accessing ISO EXPRESS data models.

Architecture

Expressir consists of 3 parts:

  1. Parsers. A parser allows Expressir to read EXPRESS files, including:

    • EXPRESS data modelling language (ISO 10303-11:2007)

    • EXPRESS data modelling language in XML (STEPmod)

    • EXPRESS XML (ISO 10303-28:2007) “Industrial automation systems and integration — Product data representation and exchange — Part 28: Implementation methods: XML representations of EXPRESS schemas and data, using XML schemas”)

  2. Data model. The data model (lib/expressir/express) is the Ruby data model that fully represents an EXPRESS data model.

  3. Converters. A converter transforms the EXPRESS Ruby data model into an interoperable export format, including:

    • EXPRESS data modelling language (ISO 10303-11:2007)

    • W3C OWL

    • OMG SysML (XMI 2.1, XMI 2.5)

    • OMG UML 2 (XMI 2.1)

    • OMG UML 2 for Eclipse (XMI 2.1)

Usage
