In the RATIONAL project, we unlocked data from very diverse sources: recipes, operating manuals for different appliance generations and operating systems, service handbooks, video documentation, and internal databases.

The challenge lay less in the volume than in the heterogeneity — different formats, languages, and structures. Our data team systematically cleaned, standardized, and consolidated these sources into a unified knowledge pool.

In principle, all text-based data sources are suitable for RAG systems: PDFs, wikis, ticketing systems, email archives, product data sheets, or FAQ collections.
