Validating Quicksand: Schema Versioning in \tauXSchema
2006
22nd International Conference on Data Engineering Workshops (ICDEW'06)

In this paper we extend τ XSchema to support versioning of the schema itself. ...
We describe how the validator can be extended to validate documents in this seeming precarious situation of data that changes over time, while its schema and even its representation are also changing. ...
Acknowledgments We thank Lingeshwaran Palaniappan and Eric Roeder for their help in the development of SCHEMAMAPPER, SQUASH, UNSQUASH, and τ VALIDATOR. ...

If past versions of XML documents are retained, what of the various integrity constraints defined in XML Schema on those documents? ...
Our approach supports temporal documents that vary over both valid and transaction time, whose schema can vary over transaction time. ...
One challenge with schema versioning is that, in this potential quicksand, anything can change, and thus must be versioned: the conventional documents, the base schema, the annotations, the schema documents ...
