FOLIO is a modular system that more than anything is meant to make it convenient and productive to use third party apps.

Some apps perform traditional functions like allowing the circulation of material, metadata management, resource management, etc.

In addition to providing these well-known functions, what makes the app concept powerful is as a space for experimentation, tweaking of workflows and support of innovative features and novel concepts.

To discover and install apps, the FOLIO store is used. Here end users can explore apps, and system administrators can install them on their FOLIO platform.
