Overlays Capture Architecture (OCA)

OCA is an architecture that presents a schema as a multi-dimensional object consisting of a stable schema base and interoperable overlays.

Overlays are task-oriented linked data objects that provide additional extensions, coloration, and functionality to the schema base. This degree of object separation enables issuers to make custom edits to the overlays rather than to the schema base itself. In other words, multiple parties can interact with and contribute to the schema structure without having to change the schema base definition. With schema base definitions remaining stable and in their purest form, a common immutable base object is maintained throughout the capture process which enables data standardisation. OCA facilitates a unified data language so that harmonised data can be pooled into multi-source data lakes for improved data science, statistics, analytics and other meaningful services.
