nmdc-metadata-suggestor-ai-tool 1.2.0

NMDC Submission portal metadata suggestor tool, powered by AI

nmdc-metadata-suggestor-ai-tool

A Python application for the NMDC Submission portal metadata suggestor tool, powered by AI. This project uses modern Python tooling with uv for dependency management and Docker for containerization.

Prerequisites

• Python 3.12 or higher
• uv (or use Docker)
• Docker and Docker Compose (for containerized development)

Quick Start

LLM Configuration:

You will need to set up a .env file. Copy the example first:

cp .env-example .env

Environment variables used by LLMClient and ConversationManager:

• AI_INCUBATOR_KEY: API key for PNNL AI Incubator (when using access_provider=pnnl).
• AI_INCUBATOR_BASE_URL: Base URL for the PNNL AI Incubator API.
• GOOGLE_APPLICATION_CREDENTIALS: Path to a GCP service account JSON file (for Vertex AI).
• VERTEX_PROJECT_ID: (Optional) GCP project id for Vertex. If not provided, the SDK will attempt to infer it from credentials.
• GEMINI_REGION: (Optional) GCP region for Gemini/Vertex (defaults to us-east5 or CLOUD_ML_REGION).
• CBORG_KEY: API key for CBORG (when using access_provider=cborg).
• CBORG_BASE_URL: Base URL for the CBORG API.

The LLMClient will read the appropriate variables depending on access_provider (set to pnnl, cborg, or gcp).

Environment variables are loaded from a .env file in the project root via python-dotenv. Variables already set in your shell take precedence over .env values (override=False is the default).

Option 1: Using uv (Local Development)

1. Install uv (if not already installed):

   curl -LsSf https://astral.sh/uv/install.sh | sh
   # or
   pip install uv
   

2. Clone and setup:

   git clone https://github.com/microbiomedata/nmdc-metadata-suggestor-ai-tool.git
   cd nmdc-metadata-suggestor-ai-tool
   

3. Install dependencies:

   uv sync
   

4. Configure environment:

   cp .env.example .env
   # Edit .env and add your API keys
   

5. Use the package in Python:

   uv run python
   

   from nmdc_metadata_suggestor_ai_tool.llm_client import LLMClient
   from nmdc_metadata_suggestor_ai_tool.recommendation_pipeline import run_recommendation_pipeline
   
   submission_object = {
       # NMDC submission JSON payload
   }
   
   client = LLMClient(access_provider="gcp")
   result = run_recommendation_pipeline(submission_object, client)
   print(result.model_dump())
   

Advanced: direct ConversationManager usage (optional)

from nmdc_metadata_suggestor_ai_tool.llm_client import LLMClient, ConversationManager

client = LLMClient(access_provider="gcp")
conversation = ConversationManager(llm_client=client)
# Add plain text context (pdf_files may be a list of local PDF paths)
conversation.add_message(text="Please summarize the submission.", pdf_files=None)
# Add any schema context to guide the model
conversation.add_schema_context("<schema description here>")
response = conversation.generate(model="gemini-2.5-flash", max_tokens=1024, gemini_temperature=0.2)
print(response)

Option 2: Using Docker

1. Clone the repository:

   git clone https://github.com/microbiomedata/nmdc-metadata-suggestor-ai-tool.git
   cd nmdc-metadata-suggestor-ai-tool
   

2. Configure environment:

   cp .env.example .env
   # Edit .env and add your API keys
   

3. Run with Docker Compose (development):

   docker-compose up
   

4. Or build and run production image:

   docker build -t nmdc-suggestor .
   docker run --env-file .env nmdc-suggestor
