The reason for nesting them is that there maybe subvalues or text marks or item marks. That way the syntax of using them does not have to change in JavaScript except to add another array position.

I could not get you code to validate, see: http://jsonlint.com/, nor could I
get my suggestion to validate either.
Here is some real code read for Universe and this does validate. The
Contact Name is multivalued attribute.

Re: [U2] JSON
At the risk of correcting Doug, if this is your input:
this
is
a
mv
test
...in JSON there could be represented a few different ways. It could be as
simple as:
["this","is","a",["mv","test"]]
Or as complex as:
{"TEST":{"part1":"this","part2":"is","part3":"a","part4":["mv","test"]}
..or even..
{"TEST":{"part1":"this","part2":"is","part3":"a","part4":{"vm1":"mv","vm2":"test"]}
...or other variations as agreed upon by sender and receiver. For MV, a
simple nested array or a simple name/value object can work beautifully.
The point is that there are several options for how the values are presented
and that flexibility can be a wonderful thing.

Re: [U2] JSON Parsing
> From: Rob Sobers > How do you handle JSON strings that have > more depth than sub-values can accommodate? PMJI - On one hand I'll say I believe it's not appropriate to approach storage of N-level structures in a 4-level MV structure (item,atb,val,sv). This is the first thing people did when they wanted to do XML to MV and most projects like this end up unfinished or limited because they're simply not prepared to deal with the real world. I think it makes more sense to create a general purpose parser which scans JSON or XML for specific data according to a schema, storing that data in a MV schema that's unique for each application. In other words, approach JSON for an Order as an Order and not as a data structure that needs to be converted to some intermediary format. This kind of development leads to something more like a XPath/XQuery processor than a simple data conversion tool. More specifically, you're pro-actively querying the JSON/XML document for specific structures, rather than just processing whatever comes along. This concept is a focal point in a lot of parser discussions, not just MV. On the other hand, here is a proposal. Over a decade ago I did come up with a way to store any number of tiers of data in MV structures. This became the the prototype storage mechanism in the TigerLogic XDMS (XML Data Management System). Atb1 contains multiple values with only top-level node names. Atb2 either has data, or Atb3 will have a pointer to an attribute further down the item where tier-2 data for that node is stored. The XML version of this used other atbs for node/element attributes, namespaces, and other metadata. So atb1 points to something like atb16. Atb16-18 are structured just like 1-3, except with tier-2 data. As you can probably see, this structure can accommodate any number of nodes at a given tier (they're just MVs), and any number of sub-tiers for each node. That said, this is only good for structures up to a few hundred K. If you have a Lot of nodes in any tier, this primary item can point to other items rather than just attributes within the same item (another fourth attribute might be allocated for this so that in any structure the first atb has MV names, second has corresponding MV values OR third has a pointer to an atb with another tier OR fourth has an item ID to another item. So for multi-item structure with an Order, you might point to a Header item and a Detail item manager, Headers might point to a complex BillTo item and a ShipTo item as well as contain local data like order ID, order date, total value, etc. The Detail "manager" item points to any number of detail items, just as you might in your application. The difference here is that the items are not structured according to your hard-coded attribute references in BASIC or dict items, they're dynamically created during a parse, and it's up to some application code to then follow the tree structures through the items to retrieve desired data. OK, there ya have it, have fun!
