dsi-workflow 1.1.2

A Data Science Infrastructure Metadatabase

DSI

The goal of the Data Science Infrastructure Project (DSI) is to provide a flexible, AI-ready metadata query capability which returns data subject to strict, POSIX-enforced file security. The data lifecycle for AI/ML requires seamless transitions from data-intensive/AI/ML research activity to long-term archiving and shared data repositories. DSI enables flexible, data-intensive scientific workflows that meet researcher needs.

DSI is implemented in three parts:

• Readers and Writers

• Backends

• Core middleware

For more information on these DSI modules, please refer to the DSI Introduction Page.

Users can interact with DSI seamlessly through two methods:

• Python API for more flexibility when loading/exporting data

• Command Line Interface API for streamlined DSI functionality without requiring any knowledge of Python

DSI Base Requirements

• python3 (3.11 tested)

• Cross-platform (Unix / macOS / Windows)

• Git

• Plugins and Backends introduce further requirements

Installation

DSI has several versioned releases and cloning from ‘main’ is the alpha-version.

Users that want to install DSI should follow our installation steps.

Release Versions

Supported release versions of DSI are tagged and found in (https://github.com/lanl/dsi/releases). Releases with minimal requirements are published on pip via (https://pypi.org/project/dsi-workflow/). To install the latest version, try the following:

python3 -m pip install dsi-workflow
