The Cultural Heritage Framework (CHF) is a research software suite that helps you build web apps to produce and publish data in the humanities. It is designed for the needs of scholarly editing, lexicography, archives, GLAM institutions, and, more generally, projects interested in making cultural heritage, books, media, or annotated bibliographies available in their own web-based research platform. A key strength of the CHF is the ability to produce portals and multimodal editions that include various data types with historical points of reference in a single system, including editing interfaces, frontends, and serialisations. Specific data models are organised as additional components around the TYPO3 extension CHF Base, which provides central data types like Agent, Location, and Period, but also multiple types of Tag and Relation to structure and connect data as well as services like import and export routines. The various components are developed and maintained by the Digital Academy, a Digital Humanities department at the Academy of Sciences and Literature Mainz.
