Modelio is an open-source UML tool developed by Modeliosoft, based in Paris, France. It supports the UML2 and BPMN standards.


The core Modelio software was released under the GPLv3 on October 5, 2011.[1] Key APIs are licensed under the more permissive Apache License 2.0.[2]


Modelio supports UML2 Profiles for XSD, WSDL and BPEL,[3] SoaML for service modelling in distributed environments;[4] and BPMN for business process modelling.[5]


Modelio was one of six tools participating in the Interoperability Demonstration held by the OMG's Model Interchange Working Group (MIWG) on December 7, 2009.[6] The event demonstrated XMI interoperability between the participating tools.[7]

The MADES Project intends to use Modelio to develop new modelling annotations with relevance to avionic and surveillance applications.[8]

Community Modules[edit]

Add-on modules are available through the Modelio community Website. These add support for TOGAF business process modeling;[9] SysML system architecture modeling (although with reduced functionality in the open source version, the requirement diagram type is not available); MARTE for specifying embedded systems, and Java code generation, reverse and roundtrip engineering.[1]
