SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires node, ruby, python3, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Rebuilding IBM Cognos content in a new BI tool by hand is slow, error-prone, and requires manual re-derivation of semantic layers and complex expression languages. This skill automates the path from Cognos to Sigma, ensuring data parity and reducing manual effort.

Core Features & Use Cases

  • Automated Conversion: Translates Cognos Data Module JSON and report-spec XML into Sigma data models and workbooks.
  • Parity Verification: Performs rigorous data parity checks against the warehouse to ensure Sigma numbers match Cognos source values to the cent.
  • Use Case: A technical analyst needs to migrate a complex financial dashboard from Cognos to Sigma. This skill discovers the Cognos content, converts the logic, wires the workbook to a Sigma data model, and verifies the output against the live warehouse.

Quick Start

Use the cognos-to-sigma skill to migrate the Cognos report and data module located in the current directory to your Sigma workspace.

FAQPage Schema
How do I automate migrating IBM Cognos reports to Sigma?▼

Automating a migration from IBM Cognos to Sigma involves translating Cognos Data Module JSON and report-spec XML into Sigma data models and workbooks while converting the underlying expression logic automatically.

Can I verify data parity between Cognos and Sigma after migration?▼

Yes, data parity verification is performed by running rigorous checks against the live warehouse to ensure that Sigma output values match the original Cognos source numbers exactly to the cent.

Do I need API credentials to convert Cognos Data Modules to Sigma workbooks?▼

Yes, executing the conversion and validation workflow requires a live Cognos session or API key alongside Sigma API credentials to access and translate the content automatically.

What is the best way to translate Cognos expression DSL to Sigma formulas?▼

Translating Cognos expression DSL to Sigma formulas is best handled by automating the conversion of semantic layers and complex expression languages to reduce manual re-derivation and error-prone effort.

Does the Cognos to Sigma migration process support complex financial dashboards?▼

Yes, the migration process supports complex financial dashboards by discovering Cognos content, converting the logic, wiring the workbook to a Sigma data model, and verifying the output against the warehouse.

What are the limitations of manual BI migration from Cognos compared to automation?▼

Manual BI migration from Cognos is slow and error-prone, requiring manual re-derivation of semantic layers, whereas automation ensures data parity and significantly reduces manual effort.
