Contracts

Offering

The EDC connector is able to provide contract offers. This feature requires four different types of extensions:

• Core Contract Extension
• Extension that implements the Asset Index
• Extension that implements the Contract Offer Framework
• Extension that implements an API to access the offers, e.g. IDS extension

Most important classes and interfaces

• Contract Offer Service
  • may be used to query offers
  • core implementation
• Contract Offer Framework
  • provide offers to the Contract Offer Service
  • create non-persistent Contract Offers Templates for a specific consumer
  • Contract Offer Templates target a range of Assets
  • implemented by extensions
• Asset Index

  • implemented by extensions

Prototypic Sequence for Contract Offer Creation

The consumer connector requests a description, that contains the contract offers, from the provider.
