SR entity relationships
In the center, we have our Entity Repository storage that holds all the metadata in a se-
cure, interpretable, and discoverable fashion. According to Conway's law ( ht-

• Decentralized (project-based)
• Domain
• Cross-domain
• Enterprise
We will start with the simplest project-based realization.
