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.
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.
