PEP: 755 Title: Implicit namespace policy for PyPI Author: Ofek Lev Sponsor: Barry Warsaw PEP-Delegate: Dustin Ingram Discussions-To: https://discuss.python.org/t/63191 Status: Draft Type: Process Topic: Packaging Created: 05-Sep-2024 Post-History: `07-Sep-2024 `__, Abstract ======== This PEP codifies an implementation of :pep:`752` for PyPI [1]_. Motivation ========== Many projects and communities would benefit from the ability to reserve namespaces. Since PyPI exists to serve the Python community, it is critical to gather feedback to ensure that everyone's needs are met. A dedicated PEP is required because the operational and policy nuances are up to each package repository to decide. Rationale ========= PyPI has been understaffed, receiving the first `dedicated specialist`__ in July 2024. Due to lack of resources, user support has been lacking for `package name claims `__, `organization requests `__, `storage limit increases `__, and even `account recovery `__. __ https://pyfound.blogspot.com/2024/07/announcing-our-new-pypi-support.html The `default policy `_ of giving paid organizations more leniency when reserving namespaces provides the following benefits: * PyPI would have a constant source of funding for support specialists, infrastructure maintenance, bug fixes and new features. * Although each application would require independent review, less human feedback would be required because the process to approve a paid organization already bestows a certain amount of trust. Terminology =========== Paid/Corporate Organization `Corporate organizations`__ are :pep:`organizations <752#organizations>` that pay for special functionality on PyPI. This PEP refers to them as paid in most circumstances for brevity and to ease understanding for non-native speakers. Root Grant A grant as defined by :pep:`PEP 752 terminology <752#terminology>`. Child Grant A grant created from a root grant with the associated namespace being a child namespace as defined by :pep:`PEP 752 terminology <752#terminology>`. __ https://docs.pypi.org/organization-accounts/pricing-and-payments/#corporate-organizations Implementation ============== Grant Applications ------------------ Submission '''''''''' Only organization (non-user) accounts have access to the grant application form. Applications for paid organizations receive priority in the reviewing queue. This is both to offer a meaningful benefit to paid organizations and to ensure that funding is available for PyPI's operational costs, including more reviewers. .. _approval-criteria: Approval Criteria ''''''''''''''''' 1. The namespace must not be something common like ``tool`` or ``apps``. 2. The namespace should be greater than three characters. 3. The namespace should properly and clearly identify the reservation owner. 4. The organization should be actively using the namespace. 5. There should be evidence that *not* reserving the namespace may cause ambiguity, confusion, or other harm to the community. Organizations that are not paid organizations will represent one of the following: * Large, popular open-source projects with many packages * Universities that actively publish packages * Government organizations that actively publish packages * NPOs/NGOs that actively publish packages like `Our World in Data `__ Generally speaking, reviewers should be more tolerant of paid organizations that apply for grants for which they are not yet using. For example, while it's reasonable to grant a namespace to a startup or an existing company with a new product line, it's not as reasonable to grant a namespace to a community project that doesn't have many users. Rejections '''''''''' Rejected applications will receive clear rationale for the decision based on the approval criteria. Applications rejected due to the namespace being too common will be persisted internally for future reviewers to reference and new applications attempting to reserve a namespace that was previously rejected for that reason will display a warning. Acceptance '''''''''' When an application is accepted for a namespace that is used by projects outside of the organization, an email will be sent to the owners of the projects notifying them of the new grant. The email will contain a link to the `namespace's page `_. Grant Types ----------- There are two types of grants. .. _root-grant: Root Grant '''''''''' An organization gets a root grant for every approved application. This grant may produce any number of `child grants `_. .. _child-grant: Child Grant ''''''''''' A child grant may be created by the owner of a `root grant `_ at any time without approval. The namespace associated with such grants must be a child namespace of the root grant's namespace. Child grants cannot have their own child grants. .. _grant-ownership: Grant Ownership --------------- The owner of a grant may allow any number of other organizations to use the grant. The grants behave as if they were owned by the organization. The owner may revoke this permission at any time. The owner may transfer ownership to another organization at any time without approval from PyPI admins. If the organization is a paid organization, the target for transfer must also be a paid organization. Settings for permitted organizations are transferred as well. .. _user-interface: User Interface -------------- .. _namespace-page: Namespace Page '''''''''''''' The namespace of every active grant will have its own page that has information such as its :pep:`open <752#open-namespaces>` status, the current owners, the time at which ownership was granted and the total number of projects that match the namespace. Project Page '''''''''''' Every project's page (`example `__) that matches an active namespace grant will indicate what the prefix is (NuGet currently does not do this) and will stand out as a pill or label. This value will match the ``prefix`` key in the :pep:`namespace detail API <752#namespace-detail>`. Clicking on the namespace will take the user to `its page `_. Visual Indicators ''''''''''''''''' For projects that match an active namespace grant, users will be able to quickly ascertain which of the following scenarios apply: 1. Projects that are tied to a `grant owner `_ will not have a visual indicator and users should solely rely on the always-present prefix. 2. Projects that are not tied to a `grant owner `_ and the matching grant is :pep:`open <752#open-namespaces>` will have a unique indicator that does not convey mistrust or danger. A good choice might be the `users `_ icon from Font Awesome or the `groups`__ icon from Google Fonts. 3. Projects that are not tied to a `grant owner `_ and the matching grant is restricted will have a unique visual indicator. This situation arises when the project existed before the grant was created. The indicator will convey inauthenticity or lack of trust. A good choice might be a warning sign (⚠). __ https://fonts.google.com/icons?selected=Material+Symbols+Outlined:groups Open Namespaces --------------- When a `child grant `_ is created, its :pep:`open <752#open-namespaces>` status will be inherited from the `root grant `_. Owners of child grants may make them open at any time. If a grant is open, it cannot be made restricted unless the owner of the grant is the owner of every project that matches the namespace. Grant Removal ------------- If a grant is shared with other organizations, the owner organization must initiate a transfer as a prerequisite for organization deletion. If a grant is not shared, the owner may unclaim the namespace in either of the following circumstances: * The organization manually removes themselves as the owner. * The organization is deleted. When a reserved namespace becomes unclaimed, the `UI `_ will reflect this such that matching projects will no longer have any indicators on their page nor will the namespace have a dedicated page. How to Teach This ================= For organizations, we will document how to reserve namespaces, what the benefits are and pricing. We will document :pep:`541` on the same pages so that organizations are aware of the main mechanism to report improper uses of existing packages matching their grants. Rejected Ideas ============== Page for Viewing All Active Grants ---------------------------------- There is no page to view all active namespace grants because this has the potential to leak private information such as upcoming products. Visual Indicator for Owned Projects ----------------------------------- There is no indicator for projects that are tied to a `grant owner `_ primarily to reduce clutter, especially since this is the most common scenario. If there was an indicator, it would not be a check mark or similar as NuGet chose because it may mistakingly convey that there are associated security guarantees inherent to the use of the package. Additionally, some social media platforms use a check mark for verified users which may cause confusion. References ========== ..
