Abstract
Techniques for implementing a scalable DOM and a pluggable DOM are provided. A scalable DOM implementation manages a DOM tree in memory to free unreferenced nodes, avoid generating nodes unnecessarily, and avoid storing multiple versions of the same data on disk. A pluggable DOM implementation includes an abstract interface that is defined between the API layer and the data layer of a DOM implementation. An implementation of the abstract interface is defined for each data source that is plugged in to the pluggable DOM implementation and that stores XML data in a different format.
