A collaboration system provides a combination of technical features to address complex collaboration between geographically distributed teams. The collaboration system implements follow and notify functionality, monitor and engage functionality, and capture functionality. The collaboration system may, for instance, tailor data flows and notifications of significant workflow events via a dynamically tuned subscription model. The system may also create a digital collaboration workspace supported by automation and machine learning functionality. In addition, the system may create documentation of collaboration with automatic recommendation of metadata tags to support search and cataloging of the documentation.
