optimade 0.16.1

Tools for implementing and consuming OPTIMADE APIs.

OPTIMADE Python tools

Latest release	Build status	Activity

The aim of OPTIMADE is to develop a common API, compliant with the JSON API 1.0 specification. This is to enable interoperability among databases that contain calculated properties of existing and hypothetical materials.

This repository contains a library of tools for implementing and consuming OPTIMADE APIs using Python. Server implementations can make use of the supported MongoDB (v4) and Elasticsearch (v6) database backends, or plug in a custom backend implementation. The package also contains a server validator tool, which may be called from the shell (optimade-validator) or used as a GitHub Action from optimade-validator-action.

Status

Whilst v1.0 of the OPTIMADE specification has been released, this repository is under development. Outstanding features required for compliance with OPTIMADE v1.0 can be tracked with the OPTIMADE v1.0 label on GitHub, which can be further filtered by backend. The release history and changelog can be found in the changelog.
