Import OSI Format

OSI files from other tools can be imported into Actian AI Analyst using Steward, the AI-powered semantic layer assistant.

Direct import of OSI files is not supported because the OSI format lacks the detail Actian AI Analyst needs for a complete semantic model. Steward intelligently fills in the gaps.

How to Import an OSI File

1. Open Steward from the right sidebar

2. Upload your OSI YAML file to the chat

3. Ask Steward to import the semantic model

4. Steward will:

   • Analyze the OSI file structure

   • Match datasets to your connected data sources

   • Infer missing metadata (types, relationships, etc.)

   • Create complete Actian AI Analyst models with proper configuration

Example Prompt

"Please import this OSI file and create models in my semantic layer. Map the datasets to my PostgreSQL data source."
