API & Integration Standards

All programmatic access to Aevum Encyclopedia is routed through our RESTful API v2. The platform enforces strict typing, pagination, and caching directives to ensure consistent performance across global CDNs.

Endpoint Architecture

Method Endpoint Description Version
GET /v2/articles/{id} Retrieve full article payload with metadata Stable
GET /v2/search/query Semantic search with faceted filtering Stable
POST /v2/contribute/draft Submit new article or revision draft Beta
GET /v1/graph/relations Knowledge graph traversal (legacy) Deprec.
Note: All responses are served with Cache-Control: public, max-age=3600, stale-while-revalidate=86400 unless explicitly overridden via X-Aevum-Cache: bypass.

Data Schema & Structure

Aevum utilizes a strict JSON-LD 1.1 compliant schema with custom extensions for academic citation, multilingual fallbacks, and knowledge graph edges. All article payloads must conform to the AevumArticle context.

article-payload.json
{
  "@context": "https://schema.aevum.org/v2",
  "@type": "AevumArticle",
  "id": "ae:qcomp-7829",
  "title": {
    "@value": "Quantum Computing",
    "@language": "en"
  },
  "version": 4.2,
  "lastVerified": "2025-09-14T08:30:00Z",
  "expertiseScore": 0.94,
  "citations": [
    {
      "type": "PeerReview",
      "source": "Nature Physics",
      "doi": "10.1038/s41567-024-02112"
    }
  ],
  "graphEdges": ["ae:superposition", "ae:entanglement"]
}

Validation Rules

  • Titles must not exceed 120 characters; alt titles supported via @language arrays.
  • expertiseScore is auto-calculated via editorial consensus algorithm (range: 0.0–1.0).
  • Articles without valid citations are flagged as unverified and restricted from public API until review.

Security & Authentication

All API requests require OAuth 2.0 Bearer tokens or scoped API keys. Read-only endpoints support anonymous access with strict rate limiting, while write operations require contributor or editor scopes.

Token Rotation

API keys rotate every 90 days. Short-lived OAuth tokens expire after 2 hours with refresh grants.

Request Signing

POST/PUT requests must include SHA-256 HMAC signatures in the X-Aevum-Signature header.

Data Encryption

In-transit: TLS 1.3 only. At-rest: AES-256-GCM with KMS-managed key rotation every 60 days.

Compliance: Aevum maintains ISO 27001, SOC 2 Type II, and GDPR compliance. All PII is pseudonymized at the edge before processing.

Accessibility & Performance Standards

The platform enforces WCAG 2.2 AA compliance across all client-rendered interfaces and structured data outputs. Performance budgets are strictly enforced via CI/CD pipelines.

Metric Target Measurement Scope
Largest Contentful Paint (LCP) ≤ 2.0s Global 3G/4G simulation
Cumulative Layout Shift (CLS) ≤ 0.08 Full page render
First Contentful Paint (FCP) ≤ 1.2s Edge cache hit rate ≥ 94%
ARIA Compliance 100% Automated audit + manual quarterly review

All interactive components must support keyboard navigation, screen reader announcements, and reduced motion preferences. SVG assets require role="img" and aria-label attributes.

Contribution Pipeline

Content submission follows a GitOps-inspired workflow. Drafts are authored in Markdown, validated against our schema, and routed through automated fact-checking before peer review.

# Machine Learning

A subset of artificial intelligence focused on...

[[citation:doi-10.1145/...]] 

## Core Concepts
- Supervised Learning
- Unsupervised Learning
- Reinforcement Learning

Pipeline Stages

  1. Lint & Schema Validation → Enforces markdown structure and metadata completeness.
  2. AI Fact-Check → Cross-references claims against verified corpus; flags anomalies.
  3. Editorial Queue → Assigned to domain experts based on tag matching.
  4. Publication → Immutable snapshot stored in IPFS with on-chain proof of revision.

Versioning & Deprecation

Aevum follows Semantic Versioning (SemVer) for all API releases and schema updates. Breaking changes require a minor version bump for APIs, with a minimum 6-month deprecation window.

  • v2.x.x → Current stable release (active development)
  • v1.x.x → Maintenance mode (security patches only)
  • Deprecation notices are communicated via Deprecation: sunset=date headers and dashboard alerts.

Rate Limits & Quotas

Plan Tier Requests / min Burst Allowance Concurrent Connections
Free / Academic 120 50 5
Professional 2,500 500 25
Enterprise Custom Custom Unlimited

Exceeding limits returns 429 Too Many Requests with Retry-After header. Abuse detection triggers automatic IP throttling and security review.
