LutaML aims to be a universal data model accessor that allows parsing data models in multiple languages, including:
-
EXPRESS (EXPRESS Language Foundation, ISO 10303-11)
-
XMI (from OMG)
-
UML in LutaML format
The Lutaml::Parser.parse method provides a single point of entry for parsing
data model files, such as:
-
EXPRESS files with
.expextension -
YAML Compressed EXPRESS CACHE files
-
XMI files with
.xmiextension -
XML files with
.xmlextension -
LutaML files with
.lutamlextension -
LutaML YAML files with
.ymlextension
Depending on the input file type, Lutaml::Parser.parse returns:
-
Expressir::Express::Model::Repositoryfor EXPRESS files -
Expressir::Express::Cache for EXPRESS CACHE files -
Lutaml::Uml::Documentfor XMI files -
Lutaml::Uml::Documentfor XML files -
Lutaml::Uml::Documentfor LutaML files -
Lutaml::Uml::Documentfor LutaML YAML files
Examples to use the Lutaml::Parser.parse:
require "lutaml"
# example.exp is an EXPRESS schema file
model = Lutaml::Parser.parse([File.new("example.exp")])
# => returns Expressir::Express::Model::Repository model
# example.exp.yaml is an EXPRESS cache file created with Expressir
model = Lutaml::Parser.parse([File.new("example.exp.yaml")], ::Lutaml::Parser::EXPRESS_CACHE_PARSE_TYPE)
# => returns Expressir::Express::Cache model
# example.xmi is an XMI file
model = Lutaml::Parser.parse([File.new("example.xmi")])
# => returns Lutaml::Uml::Document model
# example.xml is an XML file
model = Lutaml::Parser.parse([File.new("example.xml")])
# => returns Lutaml::Uml::Document model
# example.lutaml is an LutaML file
model = Lutaml::Parser.parse([File.new("example.lutaml")])
# => returns Lutaml::Uml::Document model
# example.yaml is an LutaML YAML file
model = Lutaml::Parser.parse([File.new("example.yaml")])
# => returns Lutaml::Uml::Document modelThere is a command-line interface available for parsing supported data model files.
