I would like to find or create a syntax to express business contracts programmatically, and I am looking for a robust, flexible, future-resistant way to do this.A client should be able to add a negotiation points of varying types to the contract.An example of a boolean negotiation point:There is a pre-payment penalty? (yes/no)While the above is certainly doable, it seems more difficult to describe the relationships between the negotiation points in an abstract way. Some examples:$600 is paid by Client A for inspection.The above amount is paid by Client B if condition Y (information that should have been disclosed before the inspection was not disclosed).Some other possible functionality:Virtual fields are calculated based on the numeric values of other fields.Notes:It certainly seems like XML or possibly JSON-schema are possible candidates for describing the above.  But I am open to other options.http://en.wikipedia.org/wiki/List_of_XML_markup_languagesMany thanks,
What is the most robust, extensible way to represent a contract in code?
