CodeMetaPy

Codemetapy is a command-line tool and python library to work with the codemeta software metadata standard. Codemeta builds upon schema.org and defines a vocabulary for describing software source code. It maps various existing metadata standards to a unified vocabulary. Codemetapy allows you to generate codemeta from various sources.

Tool suite: CLARIAH Tool Discovery

The following closely related tools are in a tool suite together with CodeMetaPy:

  • Web Application
  • 8 - Complete: Technology complete and qualified, released for all end-users in scholarly environments.
  • Active: The project has reached a stable, usable state and is being actively developed.

CLARIAH Tool Discovery 1.6.4

This is the over-arching project for CLARIAH Tool Discovery, its components harvest and aggregate codemeta from source repositories and service endpoints, automatically converting known metadata schemes in the process. This project holds the Tool Source Registry, pointing to all the tools that are to be harvested. It also holds the validation schema. [view more]

  • Go to CLARIAH Tools (WebApplication) https://tools.clariah.nl This is a web portal where you can find all tools (i.e. software and software services) developed in the CLARIAH project, as well as some tools from predecessors and sister projects. This list is automatically harvested from the tool producers and providers themselves, and updated daily. Our tools are designed for researchers and developers in the Humanities and Social Sciences. Not all tools are suitable for all audiences and not all tools are mature and stable, this information should be clearly indicated for each tool, so you can make an informed judgement whether a tool might be suitable for you.
