The goal of the Virtual Observatory is to make astronomical data more accessible and to provide the means to more easily analyze that data. Currently, archives hold analogous data in a variety of different representations, which impedes interoperability at the data analysis stage.
An important element of the VO is a data model that can unambiguously represent the relationships between data values and physical properties. At the CfA we are developing a data model design that can support the representation, analysis and display of data collected on different types of instruments. This model is a common, high-level framework of general-purpose components for fusion of heterogeneous data sources. From this framework, we have focused on a subset of components required to meet selected science objectives on spectral and image data.
