crystal-facet-uml creates sysml/uml diagrams to document system and software architecture.
Like a crystal shows different facets of the same thing, this application shows different views of the same system.
As software architect, you create a set of diagrams describing use-cases, requirements, structural views, behavioral and deployment views.
crystal-facet-uml keeps element names and element hierarchies consistent. It exports diagrams in svg, pdf, ps and png formats to be used in text processing systems like docbook, html, latex. crystal-facet-uml exports the model to json and xmi format; json can also be imported. The json-based data file can be stored to git, branched and merged together with your source code. This tool runs on your local linux PC and is based on glib, gdk, gtk, cairo, pango, sqlite.
How to use this program is described in the User Manual .
