Smart Contracts for Media - MCO Utils

MCO Generator

This software generates MCO contracts represented in TURTLE from Media Contractual Objects. This software is composed of:

  • a series of JSON files composing the Look Up Table (./lookup-tables)
  • a set of generators for the generation of JSON-LD objects (./generators)

The generation process starts in the ./index.js file:

  1. a JSON file representing the Media Contractual Objects is transformed into the JSON-LD format
  2. Elements in it are used to generate the Turtle file representing the MCO contract.

Media Contractual Objects (JSON strings) -> JSON-LD (JSON objects) -> MCO Contracts (turtle)

Usage

Importing this module will provide with a method getMCOFromContract that takes in input an object containing Media Contractual Objects and returns the related string in Turtle form. The utility function jsonld2turtle (used within getMCOFromContract) parses a json-ld string and serializes it into a Turtle string.

Test

To test the generator execute the following command in the main directory:

npm test

MCO Parser

This software parses MCO contracts represented in TURTLE and converts them into Media Contractual Objects. This software is composed of:

  • a series of JSON file composing the Look Up Table (./lookup-tables)
  • a set of generators for the generation of Media Contractual Objects (./generators)
  • a set of handlers to manage the inter-relation of Objects during the generation phase (./handlers)

The parsing process starts in the ./index.js file:

  1. a Turtle file representing the MCO contract is transformed into the JSON-LD format
  2. Elements in it are used to generate the Objects.

MCO Contracts (turtle) -> JSON-LD (JSON objects) -> Media Contractual Objects

For more info check the READMEs into the sub-folders.

Usage

To use the parser execute one of the following command in the main directory:

npm test <turtle file path>

Importing this module will provide with a method getContractFromMCO that takes in input a string in Turtle form and returns the related Media Contractual Objects.

Test

To test the parser execute the following command in the main directory:

npm test turtle/new/use-case-stream-small-label.ttl
