1.  Introduction

   This document defines a Trust Anchor Locator (TAL) for the Resource
   Public Key Infrastructure (RPKI) [RFC6480].  This format may be used
   to distribute trust anchor material using a mix of out-of-band and
   online means.  Procedures used by Relying Parties (RPs) to verify
   RPKI signed objects SHOULD support this format to facilitate
   interoperability between creators of trust anchor material and RPs.
   This document obsoletes [RFC7730] by adding support for HTTPS URIs in
   a TAL.

1.1.  Terminology

   The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,
   SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this
   document, are to be interpreted as described in [RFC2119].

2.  Trust Anchor Locator

2.1.  Trust Anchor Locator Format

   This document does not propose a new format for trust anchor
   material.  A trust anchor in the RPKI is represented by a self-signed
   X.509 Certification Authority (CA) certificate, a format commonly
   used in PKIs and widely supported by RP software.  This document
