Versioned Relations: Support for Conditional Schema Changes and Schema Versioning
International Conference on Database Systems for Advanced Applications, 2007 We introduce the versioned relational data model, which allows a user to apply conditional schema changes to a populated database without breaking applications compiled against an existing schema, and without loss of existing data. Our model is based on keeping a history of conditional schema changes, and converting tuples on demand to fit the correct ...

τSQWRL: A TSQL2-Like Query Language for Temporal Ontologies Generated from JSON Big Data
Big Data Mining and Analytics, 2023 Temporal ontologies allow to represent not only concepts, their properties, and their relationships, but also time-varying information through explicit versioning of definitions or through the four-dimensional perdurantist view.
