Yeti® – review XBRL taxonomies

Used primarily by organisations undertaking taxonomy development projects, Yeti® provides taxonomy exploration and review capabilities via an intuitive, browser-based interface. It is partly a taxonomy viewer, partly a collaborative discussion forum, and partly an issue-tracking system.

Yeti provides a unique environment for taxonomy publication and collaborative taxonomy development.

There are two different ways of working with Yeti, depending on your requirements:


Yeti Explore

Yeti Explore provides powerful search and exploration of XBRL taxonomies. You can use it to understand a chosen taxonomy, or investigate how others have constructed their taxonomy. Quickly locate concepts by name, label or reference and, once found, create bookmarks or provide email links to begin a discussion with other interested parties.

CoreFiling offer a free library of publicly available taxonomies, containing dozens of important taxonomies from around the world.

Yeti Explore also offers the opportunity to download Taxonomy Packages, i.e. published taxonomies already pre-packaged for seamless integration with CoreFiling solutions (and others). Included are the published versions of the EBA’s CRD IV taxonomy for the banking sector and EIOPA’s Solvency II taxonomy for the insurance industry.


Yeti Collaborate

Yeti Collaborate extends Yeti’s XBRL taxonomy review capabilities, providing a structured online discussion environment, where comments relating to taxonomy elements can be recorded, prioritised, assigned and tracked. Prioritisation and assignment of tasks, alongside visible discussion threads and email notifications, ensure transparency and accountability of issues until their successful resolution.


Improving XBRL taxonomy development

Yeti forms an integral part of our Taxonomy Management System. When used in conjunction with SpiderMonkey®, Yeti delivers up to the minute discussion threads straight to the taxonomy developers within a particular review group, encouraging immediate informed comment. Discussions on particular issues can be tracked, and Yeti allows for a designated moderator to review the comments and take the final decision about how to treat the problem in the next taxonomy revision. Transparency is the key and greatly enhances the quality of the resulting work.


Key benefits of Yeti Collaborate

  • User comment submission – Errors or discrepancies can easily be highlighted, annotated and distributed to selected users for review and action.
  • Email notification – Users can choose to be notified of new issues relating to specific taxonomies. They can then join the discussion by simply clicking the Yeti Collaborate link and posting a comment.
  • Segmented, private taxonomy review – You retain complete control over how your taxonomy is viewed. Everything, from access rights to comment regulation, is configurable, enabling you to design the framework that best supports your organisation.
  • Central taxonomy knowledge base – Data resulting from discussion threads can be used to populate an information repository for reporting purposes.


Yeti has been deployed in many XBRL taxonomy projects around the world. It is a reliable, well proven way of maintaining tight control over the taxonomy development process, avoiding duplication and promoting accuracy.


Deployment options

Yeti can either be hosted for you by CoreFiling as a dedicated internet service, or can be deployed on your own corporate servers for access via your intranet.

Yeti is the ideal companion to SpiderMonkey®, CoreFiling’s XBRL taxonomy development tool.
