ArchiCG is an innovative editor and analysis tool designed to evaluate the benefits of using Interactive Compound Graphs derived from Architectural Descriptions. It supports descriptions created in various modeling languages, including standard languages widely used by diverse stakeholders involved in enterprise architecture and digital transformation, such as ArchiMate. Note: ArchiMate® is a registered trademark of The Open Group®. ArchiCG serves professionals working with End-to-End Digital Processes, Model-Based Systems Engineering, the industrial Product Lifecycle Management (PLM) approach (as defined by CIMDATA), and Enterprise Application Interoperability. To achieve this, ArchiCG supports the creation of advanced interactive compound graph visualizations and includes algorithms for analyzing architectural descriptions and blueprints derived from various architecture description languages. ArchiCG is not intended as a replacement for established modeling platforms or enterprise repositories. Instead, it complements these systems by providing the advanced features described above. Accordingly, ArchiCG offers various import/export functions and an additional set of scripts for legacy modeling tools, such as Archi® and Enterprise Architect. Built using standardized web technologies such as HTML, SVG, and JavaScript, ArchiCG runs on web browsers without requiring additional installations. ArchiCG is a research demonstrator focused on showcasing and evaluating research outcomes related to Continuous Operational Interoperability, aimed at fostering digital collaboration within and between enterprises that employ Model-Based approaches. This demonstrator specifically addresses technologies like Linked Data, the Semantic Web, Standardized Application Protocols, advanced visualization techniques, and graph-based technologies. However, ArchiCG can also be used for simpler tasks, such as quickly visualizing data in graph format with nested nodes, importing data, or creating data structures with the ease of a mind-mapping tool.
