RegTAP Data Model

This is a VO-DML formulation of the data model described in the RegTAP Standard, and has been created to provide a machine-readable representation of that data model. The motivation for doing this is to be able to then create XSLT that will translate VOResource XML instances into RegTAP XML instances in a platform independent fashion, so that there is a standard implementation of these transformations described in the RegTAP standard.

The practical use of this code is that it can be used as part of the ingestion pipeline in a full searchable registry for transforming from an OAI-PMH response to the tables for a TAP interface on that registry.

The Transformation

The transformation from a VOResource XML instance to a RegTAP XML instance is done with this XSLT.

The Java Implementation

As well as containing the standard Java code of the model (as generated by the VO-DML tooling), the Java implementation also includes some utility classes to make running the transformation easier, as well as functionality to save those instances to a relational database.
