Welcome to the Overlays Repository – a community-driven effort to build and share task-specific overlays for the Overlays Capture Architecture (OCA). This repository enables contributors to create, share, and discover overlays that extend and enhance the functionality of Capture Bases and other Overlays.
Overlays are cryptographically linked objects that provide task-oriented definitional or contextual information to a Capture Base or other Overlays. These overlays enable users to:
- Enhance Data with Metadata – Attach additional descriptive, contextual, or structured information to underlying objects.
- Define Business Logic – Implement rules and conditions that influence the behavior of a system interacting with the overlay.
- Customize Data Presentation – Structure how data is formatted, displayed, and interpreted for different audiences.
- Transform User Experience – Modify and enrich how information is visually and functionally presented to viewers.
- Automate Processes – Guide automated agents by defining workflows, actions, or decision-making parameters.
- and more ...
Overlays allow for flexible and structured data enhancement while maintaining a consistent foundation. They play a crucial role in extending the utility of the Overlays Capture Architecture (OCA).

List of the currently submitted overlays can be found here
We welcome and encourage contributions from the community. Follow the steps below to create and submit your overlay.
Before creating a new overlay, check if a similar idea already exists. If an existing overlay addresses the same need, consider improving or extending it instead of creating a new one. The latest list of overlays can be found here
Clearly define the goal of the overlay. Each overlay should serve a single purpose and should be focused on solving a specific problem.
Provide a detailed use case explaining:
- Where and why the overlay is helpful.
- The scope and intended usage.
- Any relevant contextual framing.
- How the overlay may link to and interact with other overlays to enhance functionality.
This description helps others understand the overlay’s purpose and potential applications.
Develop an example using the OCAFILE syntax that demonstrates the overlay in action.
Follow the standard template structure to ensure consistency across all overlays. Templates help maintain clarity and usability.
Push your overlay to this repository by creating a Pull Request (PR). Ensure your submission adheres to repository guidelines.
