 In AVAnnotate, **layers** are the organizing principle for your annotations of a recording, and may be defined according to the themes, topics, or details that are guiding your interaction with the AV artifact. **Layers and annotations work together to make meaning** in an AVAnnotate project, and deciding what meaning is being communicated to an exhibit’s audience is part of the initial conceptual work required when building a project.
