		| Abstract: | We propose a framework for constructing a unified, conceptual domain model for astronomy. We believe such a model to be an essential ingredient for a future Virtual Observatory (VO). We also give a high level, skeleton proposal for this VO domain model. We indicate where details must be filled in for more specialized models. We describe one detailed base level model, a component model for Quantity, which is a generalisation of previous informal proposals. Our domain model puts it in a larger context that includes such concepts as measurement, error, and units. |
