Mayan EDMS

Mayan EDMS stores, classifies, and retrieves millions of documents with automatic OCR, workflow automation, and audit-ready access controls that organizations have relied on for over a decade. Tesseract integration extracts searchable text from scanned PDFs and images in over 100 languages, transforming paper archives into instantly queryable digital collections without manual data entry. The workflow engine routes documents through approval chains using configurable state machines that trigger notifications, enforce retention policies, and maintain complete audit trails for regulatory compliance. Version tracking preserves every revision with full diff capabilities, while GnuPG digital signatures provide cryptographic proof of authenticity and tamper detection for sensitive records. Role-based permissions combined with object-level ACLs and LDAP integration ensure documents remain visible only to authorized users, down to individual file granularity. Full-text search powered by Whoosh or ElasticSearch handles advanced queries across massive document stores with faceted filtering and relevance ranking. The Django REST Framework API enables programmatic upload, metadata extraction, and workflow triggering from external systems. Beyond simple folder hierarchies, metadata schemas, document types, tags, and cabinet structures provide multi-dimensional classification tailored to how your organization actually works. Background processing through Celery handles OCR, conversion, and preview generation asynchronously, keeping the web interface responsive under heavy ingest loads.

Benefits

  • Automatic OCR Text Extraction
  • Tesseract integration extracts searchable text from scanned documents and images in 100+ languages, making paper archives fully searchable without manual data entry.
  • Workflow-Driven Document Processing
  • State machine automations route documents through approval chains, trigger notifications, enforce retention policies, and maintain audit trails for regulatory compliance.
  • Enterprise Access Control
  • Role-based permissions with object-level ACLs and LDAP directory integration ensure documents are accessible only to authorized users with granular per-document security.
  • Complete Version History
  • Every document revision is tracked with full version history, allowing comparison between versions and cryptographic digital signatures proving authenticity and detecting tampering.

Features

  • Full-Text Document Search
  • Whoosh or ElasticSearch backends index OCR-extracted text and metadata across millions of documents with advanced query syntax, faceted filtering, and relevance ranking.
  • REST API Integration
  • Django REST Framework exposes all functionality programmatically for document upload, metadata extraction, workflow triggering, and external system integration.
  • Metadata Classification
  • Document types, metadata schemas, tags, and cabinet hierarchies provide multi-dimensional classification beyond simple folder structures for complex organizational needs.
  • Digital Signatures
  • GnuPG integration provides cryptographic document signing and verification, proving authenticity and detecting unauthorized modifications to archived files.
  • Asynchronous Processing
  • Celery task queue handles OCR, document conversion, and preview generation in the background without blocking user interactions or degrading web interface responsiveness.
