+On the Design of Data Models
+============================
+
+The IVOA has a long history of designing data models in the efforts to provide
+interoperability. However, the data models so created will be highly influenced
+by the intended use to which the models will be put

+What are the aims of the model?
+------------------------------
+
+### Labelling
+
+### Verification
+
+### Code Generation
+
+### File format definition
+
+### Querying
+
+
+Recommendations
+---------------
+
+I would argue that the principal design aim should be a descriptive one - so the models are "domain models" that try not to be influenced by any implementation aims at all.
