Open Model Based Engineering Environment


Welcome to OpenMBEE

OpenMBEE (Open Model Based Engineering Environment) is an open source collaborative engineering system. It enables engineers to work in the language of their choice and easily share and document their work across other tools.

OpenMBEE Architectures


The predecessor architecture, Execubots, stores model elements as objects in a document-oriented database, whereas Flexo provides a graph-native approach to storing and diff'ing models. Models in Flexo are not limited to enterprise model development platforms. Flexo can store anything expressed as RDF.

Relevant Repositories (repositories relevant to this architecture are prefixed with "flexo-"):


The Execubots architecture allows Systems Engineers to develop models in their enterprise model development platform and publish aspects of the model to the web.
