What is MIME type "application/ld+json"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/ld+json is a MIME type for files that use JSON-LD, which stands for JSON for Linked Data. It is a lightweight format to express structured metadata.

This MIME type tells programs that the JSON file contains linked data information. The data is both human- and machine-readable. It helps systems understand relationships and meanings behind data elements.

• Semantic Web: It adds context to data and improves content discovery.
• Data Integration: It connects data from different sources by using URIs.
• Metadata Packaging: It is used in research workflows, such as RO-CRATE, to bundle data with detailed descriptions.

Files using this MIME type often have names with extensions like JSON and JSONLD. They package data in a way that programs can easily share and reuse information.
