Advanced Portal Development with Distributed Data Providers and Multilanguage Support

This project, led by Artem Vorontsov, focuses on developing a sophisticated portal that utilizes distributed data providers across different archival legal systems. The team, based in Riga and St. Petersburg, ensures seamless data handling with full multilinguistic UI support and a universal metadata format. Key features include a comprehensive metadata import flow, optimized image preparations, and efficient document indexing. Built using JAVA and employing technologies such as MySQL, Tomcat, and Liferay, the portal is a cross-platform solution designed to facilitate efficient archival data management and searching.
