Link contract
The topic of Link contract is one that has captured the attention of many people as of late. With a long history and constant relevance in society, Link contract is a topic that has generated debate and reflection in different sectors. From its impacts on daily life to its influence on politics and culture, Link contract has proven to be a multifaceted topic that deserves to be explored in depth. In this article, we will delve into the different aspects of Link contract, analyzing its origins, evolution and its relevance in today's world.

A link contract is an approach to data control in a distributed data sharing network. Link contracts are a key feature of the XDI specifications under development at OASIS.
In XDI, a link contract is a machine-readable XDI document that governs the sharing of other XDI data. Unlike a conventional Web link, which is essentially a one-dimensional "string" that "pulls" a linked document into a browser, a link contract is a graph of metadata (typically in JSON) that can actively control the flow of data from a publisher to a subscriber by either "push" or "pull". The flow is controlled by the terms of the contract, which can be as flexible and extensible as real-world contracts, i.e., link contracts can govern:
- Identification: Who are the parties to the contract?
- Authority: Who controls the data being shared via the contract?
- Authentication: How will each party prove its identity to the other?
- Authorization: Who has what access rights and privileges to the data?
- Scope: What data does it cover?
- Permission and Privacy: What uses can be made of the data and by whom?
- Synchronization: How and when will the subscriber receive updates to the data?
- Termination: What happens when the data sharing relationship is ended?
- Recourse: How will any disputes over the contract be resolved?
Like real-world contracts, link contracts can also refer to other link contracts. Using this design, the vast majority of link contracts can be very simple, referring to a very small number of more complex link contracts that have been carefully designed to reflect the requirements of common data exchange scenarios (e.g., business cards, mailing lists, e-commerce transactions, website registrations, etc.)
Link contracts have been proposed as a key element of digital trust frameworks such as those published by the non-profit Open Identity Exchange.
