datalab-server 0.6.1

datalab is a research data management platform for materials science and chemistry.

datalab

datalab is a user-friendly, open-source platform that can capture all the experimental data and metadata produced in a scientific lab, targeted (broadly) at materials chemistry but with customisability and extensability in mind. datalab records data and metadata securely and makes it accessible and reusable by both humans and machines via the web UI and API, respectively. datalab can be self-hosted and managed deployments are also available.

You can try the demo deployment at demo.datalab-org.io and read the online documentation at docs.datalab-org.io with release notes and changelog available on GitHub and online.

Features:

• Capture and store sample and device metadata
• Connect and sync raw data directly and from laboratory instruments
• Built-in support for multiple characterisation techniques (XRD, NMR, echem, TEM, TGA, Mass Spec, Raman and more).
• Capture scientific context: store the graph of relationships between research objects.
• Python API for programmatic access to your lab's data enabling custom analysis and automation.
• Join the datalab federation: you can add your datalab to the federation for additional shared features.
• Plugin ecosystem allowing for custom data blocks, AI integration and other instance-specific code.
• Deployment and infrastructure automation via Ansible playbooks.

[!NOTE] You may be looking for the identically named project DataLab for signal processing, which also has plugins, clients and other similar concepts!

Getting started

To set up your own datalab instance or to get started with development, you can follow the installation and deployment instructions in the online documentation.

We can also provide paid managed deployments via datalab industries ltd.: contact us at [e-mail].

The main aim of datalab is to provide a platform for capturing the significant amounts of long-tail experimental data and metadata produced in a typical lab, and enable storage, filtering and future data re-use by humans and machines. datalab is targeted (broadly) at materials chemistry labs but with customisability and extensability in mind.

The platform provides researchers with a way to record sample- and cell-specific metadata, attach and sync raw data from instruments, and perform analysis and visualisation of many characterisation techniques in the browser (XRD, NMR, electrochemical cycling, TEM, TGA, Mass Spec, Raman).

Importantly, datalab stores a network of interconnected research objects in the lab, such that individual pieces of data are stored with the context needed to make them scientifically useful.
