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".
MongoDB is a document-oriented database that uses a form of JSON (BSON) as a document language. Using MongoDB and JSON-LD together provides for an efficient Semantic Web database representation appropriate for use in intermediate- to large-scale deployment scenarios where efficiency of representation and retrieval are of paramount importance.
The talk will cover:
- Typical Linked Data patterns expressed in JSON;
- Adding semantics to regular JSON through supplemental contexts;
- Design of JSON-LD objects to optimize information retrieval
- Simple querying of Mongo/JSON-LD with SPARQL
- Application development using Ruby
