Compaction

Compaction is the opposite to Expansion. The compaction process applies a context to a JSON-LD document and uses it to shorten IRIs to terms or CURIES and compress JSON-LD values to simple strings or numbers. For more information please refer to the JSON-LD API Specification.

The Compaction operation is implemented through the static method JsonLdProcessor.Compact (and in the .NET Standard framework the asynchronous JsonLdProcessor.CompactAsync method). This method accepts three parameters:

• input - a Newtonsoft.Json.Linq.JToken that represents the input document to be processed or the URI of the document to be retrieved and processed. The input may be one of the following types:
  • A JObject representing a parsed JSON-LD document
  • A JValue with a string value which is the URI of the JSON-LD document to retrieve and parse
• context - a Newtonsoft.Json.Linq.JToken that represents the context to be applied to the input document. The context value may be one of the following types:
  • A JObject representing a parsed JSON-LD context
  • A JValue with a string value which is the URI of the JSON-LD document to retrieve and parse
  • A JArray of JObject or JValue items which represents a collection of contexts to be combined and applied to the input document.
• options - a JsonLdProcessorOptions instance providing the options for the compaction operation.

The output of the method is a Newtonsoft.Json.Linq.JObject that represents the compacted JSON-LD document.
