For ESCAPE members; please follow the steps detailed in the onboarding project to finalise your contribution and the onboarding process.

The following guidelines, agreed within the ESCAPE WP3 and gathered in the ESCAPE deliverable 3.7 - “License, provenance and metadata guidelines for the software and service repository” (the link to the document will be shared soon), indicate how to provide software to the OSSR and under what conditions, in particular regarding licensing and provenance. Integration of a new entry in the OSSR is submitted to a curation phase that will validate its compliance to the following guidelines.

Guidelines and rules of participation to the ESCAPE OSSR

As the ESCAPE OSSR is built on Zenodo, its policies apply.

In addition, we have the following recommendations:

  1. Any digital resource provided into the OSSR must contain a license.

    • It most provide a machine-readable description of the license.
    • The application of the FAIR principles to the products offered in the OSSR results in the necessity to assign licenses to all relevant parts, including software code, containerized and bundled software and metadata.
  2. We strongly recommend to provide an open-source license. The choice of a permissive open-source license is advised.

    • The Terms of Use for the OSSR require contributors/providers to ensure that all copyright is respected when offering software products through the OSSR. Thus, compatibility between the licenses of derivative or combined works must be checked before the on-boarding into the OSSR and done by the contributor/provider side.
    • The choices of proprietary licenses must be justified.
    • If no license is assigned yet, it is recommended to use either the MIT or BSD-3 Clause license.
    • The metadata file itself is considered to be offered under a CC0 license.
    • For contributed software, guidelines are collected and offered to the contributors to manage the licenses in their software product.
    • Final ESCAPE open science products, as well as container images, are expected to follow these guidelines too.
  3. We strongly recommend that any software provided to the OSSR incorporates a metadata file that describes the software to be uploaded. The use of the CodeMeta project schema, and therefore the addition of a codemeta.json metadata file into the root directory of the resource is recommended for the OSSR.

    • The metadata file can be generated at using the CodeMeta generator.
    • The minimum metadata information to be added into any digital resource is the one required to create a new upload or a new version within Zenodo (see Metadata for the OSSR section). However, we strongly recommend to create a metadata file as complete as possible.
    • In relation with the previous point, it is recommended to provide a summary of user-visible changes between versions (e.g. provide a ‘release note’ with every new software release as well as fill this field within the codemeta.json) together with the OSSR software product or its documentation.
      This is essential provenance information and helps fulfilling the FAIR principles.
    • The verification that the entry contains the minimum provenance information defined in this document is the responsibility of the software provider.
    • To date, the only ZenodoCI compatible metadata context file is the codemeta.json schema file.
    • Providing a codemeta.json file with your software, in concurrence with the use of the ZenodoCI will allow the provider to define all software metadata using a single model and implementation. The integration of the software into the OSSR, as well as the use of other services (such as the production of a container for your software) will be based on this metadata.
