---+ VAO SIAv2 Prototype: Reflections on CSP Use Cases

The IVOA Committee for Science Priorities (CSP) assembled a set of use cases that it recommended should be addressed by Data Cube access prototypes.  In this document, we assess our prototype in light of these use cases.  

We note that the VAO prototype (as [[SIA2VAOPrototype][reported]]) provides support for the six required parameters that select data based on coverage and format (POS, SIZE, BAND, TIME, POL, FORMAT).  Untested support has been provided for optional parameters SPATRES, SPECRES, SPECRP, MAXREC, PUBDID, COLLECTION, ASTCALIB, TYPE.  

Some aspects of the use cases extend beyond the scope of our released demo.  We address the use cases both in terms of the released demo with its tested capabilities and in terms of the [[SIA2VAOPrototype#Details][baseline specifications]] which specifies capabiltiies that are not supported by our demo.
