ReuseIt - Copyright and License Management Library

Creates an SPDX 2.3 Software Bill of Materials based on the provided files, per ReUSE Software specification.

⚠️ NOTE ⚠️

ReuseIt (and its owner) are not part of a law firm and, as such, the owner nor the application provide legal advise. Using ReuseIt does not constitute legal advice or create an attorney-client relationship.

ReuseIt is created for the aggregation of Copyright and License information provided by the users in the files stored in their repositories. In the end, the users of ReuseIt are responsible for the correctness of the generated Software Bill of Materials, the associated licenses, and attributions. For that reason, ReuseIt is provided on an "as-is" basis and makes no warranties regarding any information or licenses provided on or through it, and disclaims liability for damages resulting from using the application.

Features

• Easy to use
• Create SPDX 2.3 Software Bill of Materials
• Leverage the Reuse Software specification

Basic Usage

import { SoftwareBillOfMaterials } from "@dev-build-deploy/reuse-it";

// Create an empty Software Bill of Materials
const sbom = new SoftwareBillOfMaterials("Example Project", "Example Tool v0");

// Add associated (related) files
await sbom.addFile("src/spdx/sbom.ts");

// Show the results
console.log(JSON.stringify(sbom, null, 2))

This will result in an SPDX 2.3 SBoM;

Basic guidelines

Adding licensing and copyright information to your file

Per the ReUSE Software specification, you can cover your files with the following approaches:

• Adding a comment header in your files;

SPDX-FileCopyrightText: 2023 Kevin de Jong <[email protected]>
SPDX-License-Identifier: MIT

• Adding a .license file next to your (binary) files
• Using DEP5 allows for specifying copyright and licensing in bulk

Please refer to the Reuse specification for more details.

NOTE: Support for .license files is still under construction

Use SPDX File Tags to enrich your Software Bill of Materials

To enrichen your SPDX 2.3 SBOM, additional File Tags can be used to add additional information to each file. For example:

SPDX-FileCopyrightText: 2023 Kevin de Jong <[email protected]>
SPDX-FileType: DOCUMENTATION
SPDX-License-Identifier: MIT
SPDX-FileLicenseConcluded: MIT
SPDX-FileLicenseComments: This file is original work of the copyright holder, and therefor the license specified in the file is correct.
SPDX-FileComment: This file is part of the public documentation.
SPDX-FileContributor: Kevin de Jong

Ignoring false positive matches

ReuseMe attempts to limit the number of false positive hits by;

• Only scanning the first 1024 characters of your files
• Ensure that SPDX- tags are the first words on a line

In case you do run into a false-positive match, you can use the REUSE-IgnoreStart and REUSE-IgnoreEnd tags to ignore snippets.

function foo(bar: string) {
  // REUSE-IgnoreStart
  if (bar.includes(
    "SPDX-FileCopyrightText is important"
  )) {
    console.log("Ru-roh")
  }
  // REUSE-IgnoreEnd
}
