Document Management

Digitize, search, and classify municipal public records.

ManagementIn development · pilot

Archival and digitization application for municipalities featuring OCR extraction, permission-scoped search, and in-browser document previews.

The problem

A municipal archive needs to find digitized documents quickly while maintaining strict role-based access control during consultation and classification.

The solution

Java application built with Spring Boot, PostgreSQL, and Keycloak authentication. Document queries respect access permissions, and a rule-based engine suggests automated classification categories.

Core capabilities

PDF upload and asynchronous OCR extraction.
Permission-aware full-text search engine.
In-app document previewing.
Rule-based classification suggestions.

How it works

Digitization and search share granular access control over official public records.

Digitized Records

PDF documents enter the archive and undergo OCR text extraction. Parsed text enables full-text search across scanned historical documents.

Query & Classification

The backend connects ingestion, search indexing, and document categorization. Rule-based engines suggest appropriate file archive classifications.

Storage & Access Control

PostgreSQL stores document metadata and audit logs, while Keycloak manages identity and permissions. Queries strictly enforce user access rights.

Search & In-App Preview

The interface allows users to search and preview documents directly inside the browser. Results strictly reflect the user’s authorized permissions.
