• Issue number: #49

Task Description

We want all license metadata to be present and to be correct. We also need full accounting for it.

Tasks

• [ ] Improve licensing info on deployed website.
  • [ ] Create a license overview page, that links to all license relevant documents and also lists the license of all available pages.
    • [x] Start with empty page. -> LicensePageExtension provides this at http://localhost:8443/net/splitcells/website/license-page.html
    • [x] Create and use a website server config, that contains a list of all license pages. The new option is located at net.splitcells.website.server.Config#licensePages
    • [x] Add name/description to every license page.
    • [o] Create a static Cell methods, that lists all relevant license resources. Use these methods in the static website server construction functions. -> For now it is ok, to use website server config.
    • [x] Note that user content is not affected by this.
    • [x] Link relevant existing pages.
      • [x] Fix all links.
      • [x] net.splitcells.network
      • [x] net.splitcells.network.system
      • [x] net.splitcells.martins.avots.distro -> Does not have relevant license files.
      • [x] net.splitcells.martins.avots.website -> Does not have relevant license files.
    • [x] Add license overview page to menu.
  • [ ] List license of every page centrally.
    • [x] Create empty page for listing all files. -> ResourceLicensingExtension
    • [ ] net.splitcells.maven.plugin.resource.list has also to create and bundle a directory containing the metadata into the jar. The directory contains a file tree, where any file corresponds to a resource managed by the resource list. The file format is a UTF-8 encoded property file.
      • [x] Create meta data files.
      • [x] Read license metadata in the file headers.
      • [x] Read copyright text metadata in the file headers.
      • [ ] Read REUSE.toml for list files without license metadata.
      • [ ] Process binary files with MetaData class.
    • [ ] Provide license metadata for page via ProjectsRenderer#metaData(String). Use this to list the licensing of every file.
      • [ ] Only provide access to metadata, to which the user has access to.
  • [ ] Show license of every page on every page.
  • [x] Link to NOTICE.md and LICENSE.md.
  • [x] net/splitcells/network/legal/Developer_Certificate_of_Origin.v1.1.txt is not correctly rendered.
• [ ] Images are licensed under the CC BY-SA 4.0.
  • [ ] Update licensing guidelines.
  • [ ] Consider add licensing metadata in images itself. See German court cases (to be refound), why no license metadata in CC BY-SA 4.0 can be a problem for other distributors.
  • [ ] Consider https://creativecommons.org/licenses/by-sa/4.0/deed.en
• [x] Ensure, that every repo has proper licensing data. -> This is done via the daily CI workflow at Codeberg.
• [ ] Simplify Java's license header, in order to simplify Java files and make them shorter. Document that the Linux kernel uses the same format and that such a header is REUSE compliant as well.
• [ ] Add denial notice of EU's copyright exception regarding machine learning.
• [ ] Add REUSE files to license pages.
• [ ] Remove big license header from Java code as this only wastes resources.
• [ ] Check and/or generate license NOTICE file, in order to ensure its correctness.

Done Tasks

• [x] test.everything should verify license data as well. -> This is done via repos.test.sh instead.
• [x] https://www.it-cisq.org/software-bill-of-materials/index.htm
• [x] Use https://reuse.software/ in order to check licensing in source code.
  • [x] Use tmp branch for this experiment.
  • [x] https://reuse.software/tutorial/
    • [x] reuse init
    • [x] ~/.local/bin/reuse lint
  • [x] Check this in daily CI for all repos. Just create the workflow for now. The actual license info will be fixed via the weekly test deployments task.
    • [x] Create command bin/repos.license.check in order to check this.
    • [x] Make license processes completely independent of GPL3 code, by providing a default license check implementation, that does nothing and inject REUSE dynamically into the process instead.
    • [x] Install OSI in CI.
      • [x] Test this in worker.execute first.
        • [x] cd projects/net.splitcells.os.state.interface && ./bin/install
        • [x] Create a general shell environment setup command. -> This is done inside bin/worker.bootstrap. A real general command is not needed for now.
          • [x] Create a project command that list all default command repositories managed by the hub repo and install these with this command via the shell project. -> The project command is bin/net.splitcells.shell.projects.peers.for.commands.
          • [x] Create a project command that list all command repositories, that are present in the current repository. -> net.splitcells.shell.repo.subs
          • [x] Use new project commands, in order to install all command repos.
          • [x] Install OSI first. Then use command.repository.register, in order to easily use command.repository.register. After that, reinstall OSI, in order to have all repos installed.
      • [x] Create general license test command. -> This command is named repos.license.check.
      • [x] Add this test to Codeberg's CI.
    • [x] Maybe this is part of the worker bootstrapping? -> Yes, this is integrated into bin/worker.bootstrap.
  • [x] The reuse-tool is licensed under the GPL-3. Is that a problem?
  • [x] Register main repo at: https://api.reuse.software/register
• [x] Create licensing guidelines.
  • [x] Create documentation stating all licence checks, that should be done.
  • [x] Add REUSE to licensing guidelines.
• [x] Document/link licensing overview in README. -> This is not relevant for now.
• [x] Add Reuse to project file system standard and document, that its LICENSES folder is exceptional.
• [x] When rendering CommonMark files, the licence info at the start of the file should be moved to the end of the file.
