MAVEN is a local host interface designed to automate the collection of metadata for DIANA datasets using URSA. It streamlines the process of gathering necessary dataset information before moving data and metadata to a specified HPC campaign directory via DSI.
If already installed, simply run: maven in your terminal.
Then, open the provided localhost URL in your preferred browser.
- Python 3.12+
It is recommended users create a virtual environment to run MAVEN with Python 3.12+.
Option A: Miniconda3
. ~/miniconda3/bin/activate
conda create -n maven_env python=3.12
conda activate maven_env # start here if virtual environment exists
Option B: Python venv
python3 -m venv maven_env
source maven_env/bin/activate # start here if virtual environment exists
pip install --upgrade pip
Option C: uv
uv venv
source .venv/bin/activate
Install MAVEN and its dependencies:
git clone https://github.com/lanl/maven.git
cd maven
pip install .
When first launching the app, you will be prompted to complete 3 fields:
- Diana Maven Directory: Where your metadata databases will be locally saved.
- AI API Key: Secret API key to connect to an AI model with URSA
- AI Base URL: Endpoint to connect to an AI model
For further instructions on setting up an AI API Key, please contact a MAVEN team member.
To move data to an HPC campaign space using DSI, contact a MAVEN team member for setup details.
The app collects 3 levels of metadata:
These sections follow the Genesis Datasheet format. URSA leverages your Project Description and Clarification responses to autofill these fields.
High-level metadata used for indexing and searching.
Domain-specific technical metadata that extracts values and types from the data.
Once all levels are complete, the app enables users to move data and metadata to the chosen HPC campaign directory.
