A survey of schema versioning issues for database systems
Information and Software Technology, 1995 Abstract Schema versioning is one of a number of related areas dealing with the same general problem—that of using multiple heterogeneous schemata for various database related tasks. In particular, schema versioning, and its weaker companion, schema evolution, deal with the need to retain current data and software system functionality in the face of ...

Beyond Schema Versioning: A Flexible Model for Spatio-Temporal Schema Selection
GeoInformatica, 2001 Schema versioning provides a mechanism for handling change in the structure of database systems and has been investigated widely, both in the context of static and temporal databases.

Versioning of Conventional Schema in the tXSchema Framework [PDF]
2012 Eighth International Conference on Signal Image Technology and Internet Based Systems, 2012 Schema versioning is an indispensable feature for applications using temporal databases and requiring an entire history of data and schema. oXSchema [7] is an infrastructure for constructing and validating temporal XML documents, but any explicit support for XML schema versioning is offered.

Schema versioning in data warehouses: Enabling cross-version querying via schema augmentation
Data and Knowledge Engineering, 2006 As several mature implementations of data warehousing systems are fully operational, a crucial role in preserving their up-to-dateness is played by the ability to manage the changes that the data warehouse (DW) schema undergoes over time in response to evolving business requirements.

A formal model for temporal schema versioning in object-oriented databases
Data and Knowledge Engineering, 2003 In this paper we present a formal model for the support of temporal schema versions in object-oriented databases. Its definition is partially based on a generic (ODMG compatible) object model and partially introduces new concepts.

A generalized modeling framework for schema versioning support
Proceedings 11th Australasian Database Conference. ADC 2000 (Cat. No.PR00528), 2000 Advanced object-oriented applications require the management of schema versions, in order to cope with changes in the structure of the stored data. Two types of versioning have been separately considered so far: branching and temporal.

Temporal JSON Schema Versioning in the JSchema Framework [PDF]
Journal of Digital Information Management, 2017 : JSchema is a framework for the management of temporal documents stored in JSON format in a NoSQL database, similar to the τ XSchema framework proposed for XML. In this work, we extend Schema to temporal schema versioning support.

Validating quicksand: Temporal schema versioning in tauXSchema [PDF]
Data & Knowledge Engineering, 2008 The W3C XML Schema recommendation defines the structure and data types for XML documents, but lacks explicit support for time-varying XML documents or for a time-varying schema. In previous work we introduced @tXSchema, which is an infrastructure and suite of tools to support the creation and validation of time-varying documents, without requiring any ...
