                <p>SysON is ready to use for editing SysML v2 models <b>out of the box</b>.</p>
                <p>However, if you are a <b>large organization</b> with specific modeling methodologies and tooling integration constraints, or a <b>software provider</b> delivering cutting-edge engineering solutions, you may need a <b>native</b> SysML v2 modeling environment <b>tailored to your needs</b>.</p>
                <p>SysON is designed for this, offering flexibility and seamless integration, making it <b>adaptable</b> to your specific requirements or <b>embeddable</b> within another application:</p>
                <ul><li><b>Extensibility</b>: SysON supports SysML v2 libraries, offering a standard and non-intrusive way to extend SysML v2. This allows you to define domain-specific (e.g., avionics, automotive, railway) or cross-cutting (e.g., requirements, safety, V&amp;V) concepts.</li><li><b>Interoperability</b>: SysON provides standard APIs to seamlessly connect with other tools. For example, you can exchange models with other SysML v2 tools or delegate service execution to engineering-specific tools (e.g., simulation, verification, code generation).</li><li><b>Customization</b>: SysON is built on <a href="https://eclipse.dev/sirius/sirius-web.html">Sirius Web</a>, a low-code modeling platform that simplifies the development of custom graphical modeling editors. This enables you to define specific visual representations (e.g., customized shapes and colors for SysML v2 types and properties) tailored to particular engineering specialists.</li></ul><p><b></b>Examples:</b></p><ul><li><a href="https://blog.obeosoft.com/introducing-methodology-support-for-sysmlv2-with-syson">Introducing Methodology Support for SysMLv2 With SysON</a></li>
