JSON is a semi-structured data format for encoding data and is a popular language for data sharing and interchange – as such it is considered a good alternative to XML. This materials in this course will cover all the core JSON syntax and data structures as well as:
– structured data as a concept
– core data structuring approaches
– the differences between XML and JSON
– when to use XML, when to use JSON

JSON itself is the language of JSON Schema and JSON-LD. We will also study core JSON Schema, a language that allows annotation and validation of JSON documents, and have an introduction to JSON-LD. JSON-LD is covered in greater depth in a follow-up course, JSON-LD Fundamentals. Both courses are follow-ups to our Certificate in XML and RDF-Based Systems.

number: no dfference between integer and floats

Boolean: true and false
array: ordered list of 0 and more values
Object: unordered collection of key/value pairs
Null: empty value

strings: text enclosed in single or double quotation marks
numbers: integer or decimal, positive or negative
booleans: true or false, no quot marks
null: means “nothing,” no quot marks

arrays are lists in square brackets, comma separated, can mix data types

objects are JSON dictionaries in curly brackets, keys and values are separated by a colon, pairs are separated by commas. keys and values can be any data type, but string is the most common value for a key

nesting : arrays and objects inside each other
can put arrays inside objects, objects inside
