Overlays Capture Architecture (OCA): Global Semantic Harmonization


Wednesday 11K

Convener: Paul Knowles @pknowles

Discussion notes, key understandings, outstanding questions, observations, and, if appropriate to this discussion: action items, next steps:


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.

A database model shows the logical structure of a database, including the relationships and constraints that determine how data can be stored and accessed. Common kinds of data models include Hierarchical database model, Relational model, Network model, Object-oriented database model, Entity-relationship model, Document object model, Entity-attribute-value model, Star schema and Object-relational database model. The data semantics across these common database models can be harmonized using OCA.

Everything is documented in the slide deck which is available here [1].
