1. Language breadth – include more languages;
2. Ontological depth – refine the common ontology;
3. Ontological clarity – elaborate the common ontology language;
4. Presentation – extend the support for presentation issues;
5. Mathematical formality – define UEML semantics formally;
6. Tool support – develop prototype tool with GUI and validation support;
7. Model management – provide support for model management in addition to language management;
8. Validation – structural and behavioural language and model validation;
9. Dissemination – make UEML known in industry and academia and as a standard;
10. Community – establish and maintain a committed and cohesive community for managing and evolving UEML and its approach.

The ten original directions were:

1. Language breadth – include more languages; 2. Ontological depth – refine the common ontology; 3. Ontological clarity – elaborate the common ontology language; 4. Presentation – extend the support for presentation issues; 5. Mathematical formality – define UEML semantics formally; 6. Tool support – develop prototype tool with GUI and validation support; 7. Model management – provide support for model management in addition to language management; 8. Validation – structural and behavioural language and model validation; 9. Dissemination – make UEML known in industry and academia and as a standard; 10. Community – establish and maintain a committed and cohesive community for managing and evolving UEML and its approach.

These and other possible future developments have been organised in a UEML roadmap comprising several research directions, each detailed by specific actions (Opdahl & Berio 2006). To some extent, further UEML development in each direction can progress in parallel without strict coordination. The ten original directions were: 1. Language breadth – include more languages; 2. Ontological depth – refine the common ontology; 3. Ontological clarity – elaborate the common ontology language; 4. Presentation – extend the support for presentation issues; 5. Mathematical formality – define UEML semantics formally; 6. Tool support – develop prototype tool with GUI and validation support; 7.
