Abstract:
In many M2M applications, direct discovery of resources is not
practical due to sleeping nodes, disperse networks, or networks where
multicast traffic is inefficient. These problems can be solved by
employing an entity called a Resource Directory (RD), which hosts
descriptions of resources held on other servers, allowing lookups to
be performed for those resources. This document specifies the web
interfaces that a Resource Directory supports in order for web
servers to discover the RD and to register, maintain, lookup and
remove resource descriptions. Furthermore, new link attributes
useful in conjunction with an RD are defined.

Hello Working Group,

Post by i***@ietf.org
A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Constrained RESTful Environments WG of the IETF.
[...]
https://tools.ietf.org/html/draft-ietf-core-resource-directory-13
https://datatracker.ietf.org/doc/html/draft-ietf-core-resource-directory-13

Given that the document is closing its completion, the authors would
like to ask the working group for reviews on it.

Big changes since -12 are:

* Added "all resource directory" nodes MC address
* Clarified observation behavior
* Reduced the significance of domains (removed from figure 2)
* Explained how endpoints from other RDs can be members of a group
* Resolve RFC6690-vs-8288 resolution ambiguities:
* require registered links not to be relative when using anchor
* return absolute URIs in resource lookup
* Explain that multiple RDs can be found, and can have absolute
addresses
* Refer to t2trg-rel-impl for server metadata / versioning
* Add explanatory text

Best regards,
Christian
