WOOL is a language definition that can be used to write dialogue between virtual agents and humans. The WOOL platform consists of (1) the dialogue language definition, (2) a powerful editor for creating dialogue scripts, and (3) a set of tools to execute these dialogues within your application of choice.


The history of WOOL

The WOOL language is based on existing open source frameworks such as Yarn and Twine. Whereas Twine is designed for interactive storytelling, and Yarn has its roots in video game development, WOOL was developed in the context of designing conversational agents for health promotion. If you are looking to build a narrative-driven video game, check out Yarn. If you want to build an interactive storytelling app, investigate using Twine. If you want to include a virtual agent in your eHealth application, your number one option is WOOL!

Specifically, the WOOL language was created in the context of the Council of Coaches project, a research and innovation project funded by the European Commission's Horizon 2020 Research Programme (Grant Agreement number 769553). You can read more about the project in our Showcase Page for Council of Coaches.

In May of 2021, Roessingh Research and Development (RRD) and Innovation Sprint (iSPRINT) — two collaborators in the Council of Coaches project — have joined forces in operating, maintaining and expanding the WOOL Platform, under the name of The Wool Foundation.

RRD and iSPRINT will jointly take up the task of maintaining and expanding the WOOL Platform, and have formalized their commitment in doing so in the WOOL Foundation Agreement that you can see below:

The launch of the WOOL Foundation is an important step in ensuring the continued support for the WOOL Platform, with two strong founding members that are using WOOL to help grow their technology, while being committed to contributing to a strong Open Source software platform.
