In many Internet of Things (IoT) applications, direct discovery of
resources is not practical due to sleeping nodes or networks where
multicast traffic is inefficient. These problems can be solved by
employing an entity called a Resource Directory (RD), which contains
information about resources held on other servers, allowing lookups
to be performed for those resources. The input to an RD is composed
of links, and the output is composed of links constructed from the
information stored in the RD. This document specifies the web
interfaces that an RD supports for web servers to discover the RD and
to register, maintain, look up, and remove information on resources.
Furthermore, new target attributes useful in conjunction with an RD
are defined.
This document is a product of the Constrained RESTful Environments Working
Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
