JSON and Linked Data Defined

Rodrigo Mehren recently wrote in DZone, “JSON is JavaScript Object Notation (said ‘Jason,’ like the name) while ‘LD’ stands for ‘Linked Data.’ The principles behind JSON  (and its LD offspring), are simplicity and interchangeability. JSON is used in the back-end to store and express a variety of data in a property:value format. JSON is likely the counterpart to what a user interprets on the front-end, e.g., ‘Allen.’ JSON’s simple rendering of the same information would run:

Property Value
name Allen

Notice the relative parsimony of plain English in comparison to JSON: in the former, simply the word and its case is enough to tell us that it’s a proper noun and most likely a personal name. The simple string ‘Allen’ cannot be interpreted or related natively by computers, which don’t have a conceptual map or mechanism to traverse one that would contextualize those concepts.”

Mehren goes on, “For machines to accomplish some of the same processing that humans do easily, developers have spent a great amount of effort to unpack and re-package exactly that data.  JSON-LD takes this context as its problem space and creates a method of publishing data to machines such that knowledge of its contents and relationships are first-class aspects of the specification. LD makes it possible not just to record and modify data objects between the browser and server, but to also meaningfully link that data to data on other websites in a standard way. When JSON is used in its simplest form, it creates an arrangement that can be rendered into a table. Moving the context beyond a singular browser-server conduit and into JSON-LD creates a graph (above).”
