Key features
The Ontology Editor combines semantic precision with practical usability. Its key features keep data definitions consistent, reusable and aligned with open standards.
Ontology (OTL) Editor
The Wistor Ontology (OTL) Editor is the starting point for creating structured, high-quality ontologies and metadata. It simplifies RDF editing into a practical workflow, enabling data architects and semantic modelers to collaborate on one shared source of truth.
Description
Ontology Editor template app
The OTL Editor is a ready-to-use application for creating, managing and publishing ontologies and metadata. It provides a structured environment to define object types, attributes and relationships, align with open standards and publish consistent models directly to the OTL Viewer or other Wistor apps. This makes ontologies actionable for data integration, digital twins and enterprise-wide data governance.
-
Semantic ontology modeling with RDF, OWL and SHACL
The OTL Editor makes semantic modeling accessible without losing technical depth. Define object types, attributes, constraints and relationships with full support for RDF, OWL and SHACL. By combining semantic precision with a user-friendly interface, data architects and modelers can create ontologies and metadata that are ready for Linked Data, digital twins and enterprise data integration.
-
Import and reuse ontologies and metadata
Save time and improve consistency by reusing what already exists. The Editor allows you to import ontologies and metadata from open standards, domain vocabularies or spreadsheets. Imported content can be extended or adapted to organizational needs, ensuring alignment with semantic web standards while avoiding duplication of work.
-
Mappings and semantic alignment
The OTL Editor helps you establish and manage mappings between ontologies, vocabularies and system-specific data models. By making these relationships explicit, the app ensures semantic interoperability across systems and domains, breaking down data silos and enabling a connected enterprise data ecosystem
-
Versioning and governance
Track every change in your ontology and metadata with built-in version control. The Editor maintains a full release history and lets you publish controlled versions directly to the OTL Viewer. This strengthens governance, supports compliance requirements and provides a clear audit trail across projects.
-
Collaboration support for data experts
Ontologies are rarely static, and the OTL Editor is built for collaboration. Multiple users can work on drafts, review content, handle change requests and capture improvements directly in the editor. This ensures that domain experts, information managers and data architects all contribute to one semantic source of truth.
-
Publishing integration with (wistor) apps
Once new versions are ready, they can be published seamlessly to the OTL Viewer or other Wistor apps. This integration makes ontologies and metadata reusable for validation, object registration or asset management, turning definitions into practical tools for data quality and interoperability.
Discription
This is a template application
Quickly create or import your ontology and metadata model, define structures and mappings, and publish with confidence. The OTL Editor makes semantic modeling practical and reusable without complex RDF editing or custom scripts
-
Flexible template that can be adapted to your own ontology or metadata model directly
-
Supports open standards like RDF, OWL, and SHACL. F uture-proof and easy to integrate
-
Ready to use for any organization, no need to build from scratch
-
Consistent governance across the organization
Description
Why it’s needed
Ontologies are complex to build and maintain. Without the right tooling they become fragmented across spreadsheets and documents, making governance nearly impossible. Manual RDF editing is error-prone, slow and accessible only to a handful of specialists.
The OTL Editor addresses this by centralizing ontology development in one platform. It enables collaboration, enforces governance and makes semantic models reusable across projects and systems. This reduces errors, prevents silos and ensures organizations can rely on ontologies and metadata as a foundation for integration, compliance and innovation.
