STEREO in the Virtual Solar Observatory Context

The Virtual Solar Observatory (VSO) was designed with the goal that it handle heterogeneous data sets from multiple observatories. With its two spacecraft and multiple instruments, the STEREO mission provides an excellent example of solar physics research based on multiple data sets, and a good test of the abilities of the VSO. Here we will discuss how the VSO will meet the key challenges that STEREO presents. In particular, the wide range of data classes and the non-stationary viewpoints of the two spacecraft demand a flexible underlying data model of the VSO.
