Meet OntoStudio
OntoStudio X is a lightweight, Excel-based IDE that brings OntoBroker’s full Java API and ObjectLogic capabilities directly into spreadsheets. No VBA macros are needed—queries and rules return results as cell values or dynamic arrays, and intermediate objects can be named and reused across formulas. It lets engineers and domain experts model, run, and audit active ontologies entirely within Excel.
Turn Spreadsheets Into…
Knowledge Capture
Knowledge capture and rule authoring by subject-matter experts
Ontology Debugging
Interactive querying, validation, and debugging of enterprise ontologies
Explainable Apps
Building explainable, spreadsheet-driven apps that leverage OntoBroker reasoning
Core Capabilities
Run ObjectLogic queries (e.g., =OB.QueryO(...)) and spill the results into dynamic arrays—perfect for large answer sets from OntoBroker.
Seamlessly connect structured and unstructured data across silos. Leverage standards-based connectors to unify data from databases, APIs, and enterprise knowledge graphs.
Connect to several OntoBroker servers at once and reference multiple ontologies in the same file—practically as many as your workbook (and Excel) can hold.
Integrate with OntoBroker through the bundled Java and Python bridges; spreadsheets remain macro-free .xlsx files.
Author higher-order rules and run them on OntoBroker 6.x from inside Excel; benefit from ObjectLogic’s expressive frames, parametrized relations, and built-ins.
✦ Process
How it works
Connect
Create a Manager to one or more OntoBroker servers and bind named ontology objects in the workbook.
Model
Declare axioms/rules using ObjectLogic via worksheet functions (with syntax-colored editing on F2).
Automate
Call Java/Python helpers where needed; intermediate objects appear as named references in cells.
