So You Want To Define a Well-Known URI

As one of the authors of the Well-Known URI specification and current Designated Expert for the registry, I field a lot of questions about how they should be used, and end up coaching a lot of folks on how to best use them. Below, I’ve summarized how I think about them. Note that these aren’t all requirements for registration – just what I consider good practice.

A crawler needs to know what the access policies for the site are, and putting it in one central place for the site avoids the need to check headers and content on every response (which would defeat many of the purposes of having such a policy).abc
