    Build a small Knowledge Graph (Google)

    This video has  -part series. In this video, Jarek Wilkiewicz introduces you to the reference architecture for support of Schema.org Actions (http://goo.gl/vw8rOJ) in the context of a specific use case (a music store). The video then then focuses on exposing entities using Schema.org markup with JSON-LD.

     

    This is the third video in a 3-part series. In this video, Jarek Wilkiewicz builds on the previous two episodes to show you how to activate a small Knowledge Graph with Schema.org Actions (http://goo.gl/vw8rOJ).

    The the first video in this series (https://www.youtube.com/watch?v=W9pRp...) covers creating and processing linked data using Schema.org and JSON-LD.

    The second video (https://www.youtube.com/watch?v=0oOwr...) focuses on data loading and graph processing using Cayley, and open source graph database written in Go (https://github.com/google/cayley).

    After watching the videos you will have a solid foundation to embark upon the Google I/O 2014 Actions Codelab (http://goo.gl/4ykgZ6).

    JSON for Linking Data

    JSON-LD, or JavaScript Object Notation for Linked Data, is a method of transporting Linked Data using JSON. It was a goal to require as little effort as possible from developers to transform their existing JSON to JSON-LD. This allows data to be serialized in a way that is similar to traditional JSON. It is a World Wide Web Consortium Recommendation that has been developed by the JSON for Linking Data Community Group before it has been transferred to the RDF Working Group for review, improvement, and standardization.

    JSON-LD is designed around the concept of a "context" to provide additional mappings from JSON to an RDF model. The context links object properties in a JSON document to concepts in an ontology. In order to map the JSON-LD syntax to RDF, JSON-LD allows values to be coerced to a specified type or to be tagged with a language. A context can be embedded directly in a JSON-LD document or put into a separate file and referenced from different documents (from traditional JSON documents via an HTTP Link header).

    “Webize” Your Data with JSON-LD

    JSON Linked Data es una forma sencilla de proporcionar significado semántico de los términos y valores en un documento JSON.

    Proporcionar ese significado en el JSON significa que las aplicaciones de los desarrolladores pueden analizar y comprender el JSON que reciben.
