JSON is a simple language for representing data on the Web. Linked Data is a technique for creating a graph of interlinked data across different documents or Web sites. JSON-LD brings both together to describe dereferencable entities that may be further used to find more information about an entity, creating a "Web of Knowledge".
JSON-LD is intended to be a simple publishing method for expressing not only Linked Data in JSON, but also for adding semantics to existing JSON.
The talk will cover:
• typical Linked Data patterns expressed in JSON;
• adding semantics to regular JSON through supplemental contexts;
• automated reformatting of JSON through expansion, compaction and framing;
• data normalization and implications for digitally signing JSON documents;
• relationship with and independence from RDF.
