SCHEMA ST4

What SCHEMA ST4 is

SCHEMA ST4 is a component content management system for creating and maintaining technical documentation. It is aimed at companies handling multiple product variants, languages, or publishing channels, including manufacturers in mechanical engineering, medical technology, electronics, and automotive. Teams can create modular content once and reuse it across documents and product variants; changes to reused content are applied wherever it appears.

An integrated XML editor supports structured authoring, with AI assistance that checks language, terminology, and style in real time. Stakeholders can comment in approval workflows and track document status. Publishing destinations include PDF, HTML, Markdown, web, apps, and machine control systems. Open interfaces connect with ERP, PLM, and translation memory systems, and a standardized COTI-based interface supports translation agencies. ST4 is offered as a cloud or on-premises option, with web and self-hosted platforms. The paid product has a 28-day trial and pricing by consultation. Quanos provides rollout support covering data migration, configuration, training, and ongoing support. For ST4 Cloud, Quanos says customer data is stored on servers in Germany, the service is ISO 27001-certified, and it is GDPR-compliant. Quanos traces SCHEMA GmbH's founding to Nuremberg in 1995; the Quanos Group was formed in January 2020.
