About
JavaScript Object Notation for Linked Data (JSON-LD) is a lightweight linked data format used to embed structured data into web pages in a machine-readable form.
It is based on 
JSON and standardized by the 
W3C, uses context mapping to link data to the Schema.org vocabulary, allows embedding via script tags without affecting page markup, and supports graph-based structures for representing entities and their relationships.
Microdata is an 
HTML specification used to embed structured metadata within web page content by annotating elements with machine-readable attributes.
It uses attributes such as itemscope, itemtype, and itemprop to define entities and their properties directly in markup, supports vocabularies such as Schema.org, and is one of the structured data formats supported by Google alongside 
JSON-LD and 
RDFa.
