 This specification defines the fundamental requirements for a claim to be classified as a "linked claim." It introduces the concept of a LinkedClaim profile, outlines how an ecosystem can achieve conformance with the linked claim requirements, and provides guidance on specifying additional requirements through a profile. However, it does not define any specific profile or provide an implementation guide, which are addressed in separate documents.

 Decentralized Web Node is a _DRAFT_ specification under development within the [Decentralized Identity Foundation](https://identity.foundation) (DIF). It is an active work item of the [Linked Claim Incubation Lab at DIF](https://github.com/decentralized-identity/labs/blob/main/proposals/linked_claims/001_proposal.md)  It incorporates requirements and learnings from diverse stakeholders across sectors into a shared specification that meets the collective needs of the community.
