| # Human Usable Textual Notation |
| |
| HUTN is an OMG standard for storing models in a human understandable |
| format. In a sense it is a human-oriented alternative to XMI; it has a |
| C-like style which uses curly braces instead of the verbose XML start |
| and end-element tags. Epsilon provides an implementation of HUTN which |
| has been realized using ETL for model-to-model transformation, EGL for |
| generating model-to-text transformations, and EVL for checking the |
| consistency of HUTN models. |
| |
| ## Features |
| |
| - Write models using a text editor |
| - Generic-syntax: no need to specify parser |
| - Error markers highlighting inconsistencies |
| - Resilient to metamodel changes |
| - Built-in HUTN-\>XMI and XMI-\>HUTN transformations |
| - Automated builder (HUTN-\>XMI) |
