Preston,
The plan has been for you to get familiar with XQuery and then get to a point where you can start writing the function implementations.
assign is an operator in Algebricks. All the operators you see there are implemented already.
QUANT_ONE, QUANT_QUESTION are constants used to specify the quantifiers for the types, so there is nothing to be done there.
I need to fix the compilation path in VXQuery to create correct plans so the optimizer does the right thing. Let me take care of that and I will let you know the next steps.

Now that we seen the plans and know the functions required for each of the plans. Whats next? Should I start to tracing the code for generating these paths or look at creating these functions in VXQuery? Also, what about the following items: - assign - QUANT_ONE, QUANT_QUESTION, ... Do we need to do build out support for these items or does that exist? Number Query Functions - data - add - subtract - multiply - divide String Query Functions - data - concat - string-join - substring - string-length - upper-case - lower-case Operators - promote - concatenate
