About
Dublin Core is a metadata element set used to describe documents and other digital or physical resources in a standardized way.
It defines 15 core elements including title, creator, subject, description, publisher, and date, and provides a simple, extensible schema that supports cross-domain resource description and interoperability across different systems.
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.
