Topic Tree
Zet Universe

[This is preliminary documentation and is subject to change.]

The core of the Zet Universe Semantic Information Processor is the Topic Tree with the associated Topic Queue Service, which is a dynamically formed queue of all major changes to the entities.

The Topic Tree

The Topic Tree is used as the central notification system which is used by all plugins to drive data import, analysis, and enrichness processes. It is extendable; that is, each plugin can define its own topics and subtopics, and use them as the way to communicate with other plugins, building a custom pipeline.
