Hi Riyafa,
there’s no problem with your questions - that’s the right way to go!
It’s also grate that you started to work on a proposal.
The challenge is just that we can’t always respond fast enough :(

I read through the specification on JSONiq extension to XQuery [1] and

first and
implement for failing test cases?
It would certainly be a good approach to write tests before implementing
the
functionality. For XQuery we got the test suite from the W3C working
group,
but for JSONiq we don’t have one. However, I don’t think that a
complete
suite is useful upfront. Rather we should add tests for each "feature"
before
implementing the feature.
Further I would like to know if there is an architecture diagram or
class
diagram (that I could have access to) for VXquery so that I could
indicate
what additional classes and packages that needs to be created in order
to
support JSONiq. If I cannot have access to one I hope it would be fine
if I
only mention the additional packages and classes that needs to be
created.
I don’t think that there’s a class diagram available. In the past
I’ve seen
tools that generate UML from source code, but I think that the diagram
might
become too big to be useful soon. I think that writing things down in
text
is fine.

A few comments:
- While there is a standalone JSONiq language, we’re really only
looking
at the JSONiq extension for XQuery here.
- The update primitives in 5. are not something that we’re considering
as
VXQuery has currently no support for the XQuery Update Facility [1].
- Some additions to the parser are needed as well - e.g the constructors
for objects and arrays and the dynamic function call syntax.
Does this help?
Cheers,
Till
