That is exactly my point. Most people have a common definition of the terms. Just like I hear many people say something like "Do you have OpenView?" I know that they usually mean OpenView Network Node Manager but OpenView is a suite of products and Network Node Manager is but one product in that suite. People have their common terminology and use it even though it is not quite accurate.

Network Appliance makes NAS devices that connect via ethernet. However, they also sell fibre channel HBAs for their Filers to allow direct attach via SAN. Conversely, there are all kinds of SAN disk arrays out there that attach via fibre channel but you can easily buy a NAS head and connect via ethernet and call it a NAS device.

This type of stuff really confuses people and that is why I offered two definitions and said that most people refer to SANs as their fibre channel network and the arrays on it. It is not fair to say they have nothing to do with each other because they do coexist with each other.

NAME
json - JSON parser SYNOPSIS
package require Tcl 8.4 package require json ?1.0? ::json::json2dict txt _________________________________________________________________ DESCRIPTION
The json package provides a simple Tcl-only library for parsing the JSON http://www.json.org/ data exchange format as specified in RFC 4627 http://www.ietf.org/rfc/rfc4627.txt. There is some ambiguity in parsing JSON because JSON has type information that is not maintained by the Tcl conversion. The json package returns data as a Tcl dict. Either the dict package or Tcl 8.5 is required for use. COMMANDS
::json::json2dict txt Parse JSON formatted text txt into a Tcl dict and return the value. EXAMPLES
An example of a JSON array converted to Tcl. A JSON array is returned as a single item with multiple elements. [ { "precision": "zip", "Latitude": 37.7668, "Longitude": -122.3959, "Address": "", "City": "SAN FRANCISCO", "State": "CA", "Zip": "94107", "Country": "US" }, { "precision": "zip", "Latitude": 37.371991, "Longitude": -122.026020, "Address": "", "City": "SUNNYVALE", "State": "CA", "Zip": "94085", "Country": "US" } ] => {Country US Latitude 37.7668 precision zip State CA City {SAN FRANCISCO} Address {} Zip 94107 Longitude -122.3959} {Country US Latitude 37.371991 precision zip State CA City SUNNYVALE Address {} Zip 94085 Longitude -122.026020} An example of a JSON object converted to Tcl. A JSON object is returned as a multi-element list (a dict). { "Image": { "Width": 800, "Height": 600, "Title": "View from 15th Floor", "Thumbnail": { "Url": "http://www.example.com/image/481989943", "Height": 125, "Width": "100" }, "IDs": [116, 943, 234, 38793] } } => Image {IDs {116 943 234 38793} Thumbnail {Width 100 Height 125 Url http://www.example.com/image/481989943} Width 800 Height 600 Title {View from 15th Floor}} BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category json of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. KEYWORDS
