What Fonto Editor is

Fonto Editor is an online XML editor for people who do not have XML or structured content authoring experience. It checks edits in real time against the schema in use, including DITA, JATS, S1000D, and custom schemas. Authors can add comments and metadata, restructure content by dragging and dropping, copy and paste, and track changes. The editor supports version control, translation, and review workflows, and can show publishing previews in formats such as HTML, PDF, e-books, learning platforms, magazines, and manuals. It also integrates MathType by WIRIS for creating mathematical formulas.

Fonto says the editor supports any XML schema, including BITS, DocBook, NISO STS, TEI, and bespoke schemas. Its open architecture integrates with digital asset management systems, content management systems, and repositories; listed integrations include Alfresco, OneDrive, SharePoint, Adobe EM, Google Drive, OpenText, SDL Tridion Docs, MarkLogic, and FileNet. Fonto reports that it has handled publications exceeding 400 pages, 60,000 topics, and gigabytes of data. The product is available through API, self-hosted, and web platforms. It does not store content or provide workflow, so it needs a CMS, workflow system, or repository integration.
