To standardize data input, an Excel template aligned with EN 15804 was developed. Users can upload both the Excel file and the corresponding PDF of an EPD to a digital platform. A Python script processes these inputs, generating a JSON file that follows the ECO Portal EPDs schema, ensuring interoperability. The resulting JSON, Excel, and PDF are archived, and the EPD data is ingested into the Neo4j knowledge graph, supporting advanced data integration, analysis, and decision-making. 9 - Indústria, Innovació i Infraestructura Preprint Àrees temàtiques de la UPC::Informàtica::Aplicacions de la informàtica Environmental Product Declarations (EPDs) Digitalization Knowledge graph Interoperability Digitalization of environmental product declarations
