Texto Interactivo en Educación Ciudadana (Interactive Text in Citizen Education)

Look at https://www.bcn.cl/formacioncivica/texto_interactivo.html

This is not my project but one from a good colleague, Werner Westermann at the Library of Congress in Chile. It's a version of a national curriculum guide published as a series of rather well used H5P Interactive Book content. I am not sure if how this was developed, but Werner did share he had experimented with the Smart Import tools to generate H5P.

And I am not literate in Spanish, but flipping google translate on the main page seemed to carry the translation through the H5P content.
