httk-optimade

This repository was merged with httk-web into httk-serve. Do not use this repository.

httk-optimade is a httk₂ module providing a generic implementation of the OPTIMADE protocol; the entry schemas it serves are supplied by providers (such as httk-atomistic's structure provider) through the neutral httk.core.EntryProvider contract.

The served API version is OPTIMADE v1.3.0. Implemented optional parts of the specification include sorting, the references, files, and trajectories entry types, relationships with the include query parameter, per-property metadata, the partial data protocol (JSON Lines format and dimension_slices) with the compact list representation, and the license/available_licenses/warnings meta and base-info fields. Optional parts that remain unimplemented: cross-source sort merging, filtering on relationship .target.*/.description/.role properties, the sparse JSON Lines layout, index meta-databases, and rejection of unrecognized query parameters. See docs/how_it_works.md for the architecture and the backend/web seams.

The implementation was ported from the OPTIMADE server in httk v1 (which served OPTIMADE v1.0.0) and then upgraded to v1.3.0. The legacy client-side validation/ subpackage has intentionally not been ported; use the official optimade-validator tool to check conformance of a running server.
