The long-standing RFC Production Center practice of tagging RFCs with keywords makes it easier to find RFCs related to a particular topic or technology, but some older RFCs lack keywords and the topics have never been applied in an organized manner.  The new subject tags on RFCs aim to help readers find related RFCs in a more structured way. The design principles for the subject tags, the full taxonomy, and the code used to generate them can be found in a dedicated GitHub repository, which includes a separate tag browser that allows you to examine the taxonomy in detail. Issues with the tags can be raised directly in that repository.

Some of the new features on RFC-editor.org require an account at account.ietf.org. For the moment, these accounts are separate from the IETF Datatracker accounts, though there is a plan to merge these in the future. RFC-editor.org readers who do not use Datatracker will not need to take any other actions when that merge occurs.

Logged-in website visitors now have the ability to create and share personal sets of RFCs to organize them within their accounts.

Visitors with accounts can subscribe to RFCs or subject tags to receive notifications about changes, errata, and newly published RFCs. Notifications will appear on account pages and via email digests.

As a first step towards engaging RFC consumers more generally, visitors can apply personal ratings to an RFC and view aggregate ratings when they exist.

To gather data that will help improve the website, pop-up surveys will be offered to some visitors, asking simple questions about the site in general or about a specific RFC.

A feature not launched today but expected to be available in the near future will highlight RFCs that are of particular interest at the moment. This feature will build on data related to an RFC, including anonymized and aggregated page view numbers. This feature is currently being tested and validated; once it is publicly available we expect broader use will help refine it further.
