Hi Holger, I have looked at Magic Properties, and thought they were relevant to my question, but I couldn't find any examples of how to create a magic property that returns multiple values. On the page you linked to, it says "Magic properties can also take multiple arguments and result values using a (rather obscure) list syntax - these cases are technically supported but complex to represent in the SPIN RDF syntax".
Could you provide more detail or a link that describes this list syntax for creating a magic property that returns multiple values? Thanks!
