Who maintains OpenIM

OpenIM is an independent reference model maintained by Georgios Antikatzidis, an enterprise architect with more than 25 years in financial services. His work spans investment management, banking, enterprise architecture, data and AI.

The model grew from repeated architecture work across investment and banking firms. Teams often had detailed standards for individual concepts, while the firm-level map remained local to a vendor, consultancy or internal architecture practice.

OpenIM publishes that firm-level map under the MIT licence. Its source and governance are public, along with the issue history.
