dst vs OnCo

Q: Which is better, dst or OnCo?

By GitHub stars, OnCo has more community adoption, but the best choice depends on your specific use case.

dst: dst (data serve tool) is an open-source semantic layer and MCP server that connects AI tools like Claude, ChatGPT, and Copilot to your data warehouse, ensuring data accuracy and governance. It provides a controlled interface for AI to answer plain language questions with grounded numbers, SQL, confidence grades, and attached receipts, bringing engineering best practices to the data-to-AI lifecycle.; OnCo: OnCo is an open, cited knowledge graph dedicated to cancer, aiming for total information dominance across all aspects of the disease. It provides a comprehensive repository of data, research, treatments, and patient information accessible via a website, static JSON API, and command-line tools.

Features

dst

01Governed Semantic Layer: Provides a single, controlled interface between AI and data warehouses, ensuring AI answers are based on defined business logic.

02Automated Data Testing & Validation: Every approved answer becomes a regression test, running on every deploy to prevent silent data inaccuracies.

03Transparent Data Answers with Receipts: Every AI-generated data answer includes the producing SQL, confidence, and a verifiable receipt, enhancing trust and auditability.

04Engineering Best Practices for Data Serving: Incorporates software engineering principles like version control, CI/CD, and audit trails for managing data serving to AI.

05Typed Serving & Clarification: Instead of guessing, dst uses typed decisions to compile SQL and can ask for clarification when a word is ambiguous.

OnCo

01Interactive Website Interface: Offers filters, tooltips, molecule renderings, a graph explorer, and an 'Ask OnCo' question answering system.

02Static JSON API: Provides programmatic access to the corpus with CORS, Markdown context files for language models, Atom feeds, and RDF triples.

03Command-Line Tool (CLI) and MCP Server: Enables agents and scripts to search, fetch, compare, and query the cancer corpus directly.

04Multi-language Support: Offers eight interface languages with translated TL;DRs to enhance accessibility for a global audience.

Use Cases

dst

↳Providing accurate and governed data answers to conversational AI agents (e.g., ChatGPT, Claude) from enterprise data warehouses.

↳Preventing AI models from generating incorrect or speculative data analysis by grounding their responses in defined business logic and validated SQL.

↳Implementing a robust data governance framework for AI applications, ensuring all data access and interpretation are auditable and compliant.

↳Automating regression testing for data definitions and metrics, ensuring that changes to the semantic layer do not silently break existing data interpretations.

↳Developing internal AI agents or copilots that require reliable and verifiable access to an organization's analytical data.

OnCo

↳Patients and Carers: Access plain-English information on cancers, treatments, side effects, and evidence-graded complementary approaches.

↳Clinicians and Researchers: Explore the state of the art, history, ongoing research, and bottlenecks in cancer, with direct links to primary sources.

↳AI Agents and Scripts: Programmatically search, fetch, compare, and query the knowledge graph for data integration, analysis, and LLM context.

↳Investors and Policymakers: Understand market landscapes, treatment approvals by region, funding, and the overall progress in oncology.
