Solution to publish a 300+ process model library

I'm a consultant for an organization and our team has modeled over 300 processes in Bizagi. They are currently stored in a simple folder system but we have ideas for publishing it like a Process Architecture with different layers and process sequences.

Could you suggest, at the top of your head, any solutions to publish this files? We would like to build a navigable portal to browse through them. Good solutions would allow a tree like view of the processes, and perhaps read and allow search over the .bpm or .bpmn files.

Free or open source ECM or DMS would also work. I do not know any of them so I appreciate any suggestions.
