Welcome to LeoDB

LeoDB is a free, collaborative knowledge database that anyone can edit. The project began in 2019 with the goal of creating a comprehensive, neutral, and accessible repository of human knowledge across all fields of study.

Overview

LeoDB operates as a decentralized knowledge repository, maintaining strict standards for accuracy, neutrality, and verifiability. All content is contributed by volunteers worldwide and undergoes continuous peer review by the community.

The database contains articles covering science, technology, history, geography, arts, culture, and numerous other topics. Each entry is meticulously cross-referenced with reliable sources and undergoes regular quality audits.

Database Structure

The LeoDB architecture follows a distributed model with multiple redundant nodes ensuring high availability and data integrity. The system utilizes:

• Primary Nodes: Core servers hosting the master database
• Edge Nodes: Regional caches for improved access speed
• Backup Systems: Automated daily snapshots and replication

Data Organization

Content is organized using a hierarchical taxonomy system with multiple levels of categorization. Each article contains structured metadata including creation date, revision history, contributor information, and citation references.

Editorial Guidelines

Contributors must adhere to strict editorial standards:

• Verifiability: All factual claims must be supported by reliable sources
• Neutrality: Content must present multiple perspectives fairly
• No Original Research: Articles summarize existing knowledge
• Notability: Topics must meet minimum relevance criteria

These principles ensure that LeoDB maintains its reputation as a trustworthy reference source used by students, researchers, and professionals globally.

Technical Infrastructure

The platform runs on open-source software stack optimized for high-traffic read operations. Key technical components include:

The database engine uses a custom indexing system that enables near-instantaneous full-text search across millions of articles. Content delivery networks (CDNs) distribute static assets globally, reducing latency for international users.

All data transmissions are encrypted using industry-standard protocols (TLS 1.3), and the system implements multiple layers of DDoS protection and rate limiting to ensure service stability.

API Access

Developers can access LeoDB data through RESTful APIs and structured data exports. The API supports various query formats and returns responses in JSON or XML. Rate limits are applied to ensure fair usage.

Community and Governance

LeoDB is maintained by a global community of volunteers including subject matter experts, editors, developers, and administrators. Decisions regarding policies and major changes are made through community consensus.

The project is supported by donations and operates as a non-profit initiative. Financial transparency reports are published quarterly, detailing all income and expenditures.

Contributing

Anyone can contribute to LeoDB by creating an account. New users are encouraged to start with minor edits and familiarize themselves with the style guide before creating new articles. Experienced contributors mentor newcomers through the editing process.
