[urn] Registration Request for `csa` namespace from SDO


As an IESG recognized SDO, the Connectivity Standards Alliance is requesting the registration of the urn namespace “csa” for use in its specifications under the fast-track provisions of RFC 8141


Template below:


Namespace Registration for Connectivity Standards Alliance (CSA)

Namespace Identifier:  csa

Version:  1

Date:  2025-03-18

Registrant:

   Name:
       Connectivity Standards Alliance 

   Address:
       Connectivity Standards Alliance
       508 2nd Street, Suite 109B, Davis, CA 95616 USA

   Designated Contact Person:
       Name: Aron Rosenberg
       Email: iana-registrations&csa-iot.org

   Organization Type:
       Standards Development Organization (non-profit corp)
       (requesting fast-track registration procedure)

Purpose:

The Connectivity Standards Alliance (CSA) is an internationally recognized 
standards development organization developing standards such as Zigbee
and Matter. The CSA is made up of independent Working Groups which 
define the individual protocols it creates. CSA’s Matter Working Group,
develops standards for smart home products built on IP technologies.

The CSA’s Matter Working Group references other accepted industry standards
where possible, such as MPEG-CMAF, W3C/WHAT HTML5, W3C/IETF WebRTC,
MPEG-DASH, and MPEG4. Through the process of this referencing, the
Matter Working Group also produces artifacts such as binding specifications or
compatibility schemes that are intended to enable common understanding and
interpretation within a runtime environment. To provide a common 
well-defined identifier for these artifacts in areas where those other standards
utilize URNs, the Matter Working Group intends to use the URN syntax for its
specific payloads, and therefore the CSA is requesting a formal namespace
to be assigned to the organization.

The URNs assigned by CSA will be used in a variety of systems ranging from 
device-to-device and device-to-server deployment scenarios.

The CSA members and larger population of Internet developers will benefit
from the usage of the assigned URNs as they will identify the binding
specifications and compatibility schemes defined and maintained by the CSA.

Syntax:

URNs assigned by CSA will have the following structure based on the 
organizational structure of the resources specified in the CSA 
specifications:

   urn:csa:{NSS}

where the syntax of “NSS” is specified in Section 2 of the URN Syntax 
requirements [RFC8141]. The CSA plans for the NSS to have a hierarchical 
structure with that structure being defined in CSA issued specifications with 
each Working Group managing its NSS. The first intended use would be under:
   
   urn:csa:matter:{NSS}

Assignment:

The individual URNs shall be assigned through the formal process of 
standardization by the CSA’s Working Groups. The latest information about 
CSA defined standards and specifications, including Matter specifications,
can be found at https://csa-iot.org/ 

Security and Privacy: 

There are no additional security considerations other than those 
normally associated with the use and resolution of URNs in general, 
which are described in [RFC1737] and [RFC8141].

This document registers a namespace for CSA URNs. CSA may assign special 
meaning to certain of the characters of the Namespace Specific String 
(NSS) in its specifications. Any security consideration resulting from 
such an assignment is outside the scope of this document.

Interoperability:

There are no known interoperability issues for the requested urn 
namespace.

Resolution:

Resolution mechanisms are not intended or anticipated for URNs assigned 
within the namespace as they will be utilized across a wide variety of 
systems and use cases.

Documentation:  

None.

Additional Information:

None.

Revision Information:

None.
