Resumo

This paper presents Valide Editoras, a tool designed to support the production and technical validation of digital educational textbooks within the ecosystem of Programa Nacional do Livro Didático - (PNLD). The platform integrates automated validators based on technical and regulatory requirements defined in official specification documents. The paper describes the validation architecture and workflow adopted by publishers during the development and revision of digital textbooks. Operational results characterize the use of the tool during submission and revision processes and show an observed reduction in automated nonconformities across the analyzed cycles. The proposed approach contributes to discussions on scalable infrastructures for the validation of digital educational resources.
