# NobleID — The Universal Identity Protocol

> NobleID is the open standard for verifiable attribution. It binds creators, assets, and proofs into a single, permanent address for the knowledge economy.

## What is NobleID?

NobleID provides persistent, human-readable identifiers for research works, researchers, and institutions. It unifies four capabilities:

1. **The Work** — Persistent links for papers, datasets, software, and multimedia that never break.
2. **The Person** — Researcher identity: ORCID, affiliations, profiles, and attestations in one place.
3. **The Proof** — Cryptographic Knowledge-Proof Receipts for each version with content hashes and timestamps.
4. **Support** — Privacy-preserving support and licensing flows with automatic split distributions.

## Key Features

- **Persistent Identifiers**: `nobleid.org/yourname` — human-readable, permanent URLs
- **Version History**: v1, v2, v3 transparently tracked with receipts per version
- **Multi-Database Search**: Search across PubMed, OpenAlex, Semantic Scholar, arXiv, Scopus, EuropePMC, and more
- **Identity Verification**: Multi-signal trust scoring with Didit identity verification
- **ORCID Integration**: Link your ORCID for cross-platform identity
- **Provenance Receipts**: Cryptographic proof of authorship and timestamps
- **Open Access Indicators**: Identify open access papers across databases
- **Revenue Splits**: Automatic distribution for co-authors and collaborators

## Auto-Generated Knowledge Pages

NobleID provides rich, auto-generated profile pages for:

### Research Topics
- URL pattern: `https://nobleid.org/topic/{topic-slug}`
- Examples: https://nobleid.org/topic/machine-learning, https://nobleid.org/topic/crispr, https://nobleid.org/topic/quantum-computing
- Content: topic description, publication statistics, trend charts, highly cited papers, leading researchers, related topics

### Institutions
- URL pattern: `https://nobleid.org/institution/{name}`
- Examples: https://nobleid.org/institution/Harvard%20University, https://nobleid.org/institution/MIT
- Content: institution profile, publication count, citations, h-index, top researchers, notable papers, recent publications (live feed), research focus areas, associated institutions

### Researchers
- URL pattern: `https://nobleid.org/researcher/{name}`
- Content: publications, citation metrics (h-index, i10-index), co-author network, research interests, institutional affiliations, publication timeline
- Note: Researchers can claim their profiles for verified identity

### Papers
- URL pattern: `https://nobleid.org/paper/{id}` or `https://nobleid.org/work/{arkId}`
- Content: full metadata, abstract, authors, citation graph, related papers, provenance receipts

## API
