Cross Registry Information Service Protocol
charter-ietf-crisp-02

In the standard operation of Internet systems, various labels and data
are managed globally -- domain names, IPv4 and IPv6 addresses,
etc. From time to time, for operational and administrative purposes,
users of the Internet need to be able to find and access registered
nformation associated with those labels.

The CRISP (Cross-Registry Information Service Protocol) WG will
define a standard mechanism that can be used for:

• finding authoritative information associated with a label,

• a protocol to transport queries and responses for accessing that
  information,

• a first profile (schema & queries) to support commonly-required
  queries for domain registration information,

• a second profile (schema & queries) to support commonly-required
  queries for numbering resource information. ("numbering resources"
  is used to refer to IP addresses and ASNs)

The WG will strive to preserve an extensible architecture so that the
work possibly be useful in the future to other types of registries
beyond those specifically considered by the group.

Specific topics that are NOT goals of this WG are:

• Backwards compatibility with existing administrative directory
  services such as WHOIS.

• Provisioning of data into registry or registrar systems. CRISP
  provides a uniform access to and view of data that may be held in
  disparate backend servers.

The CRISP service definition will define:

• a standard mechanism that can be used to determine the
  authoritative server(s) for information about a given label

• a single mandatory to implement protocol for transporting
  application queries and responses, including

• expression of input query

• expression of result sets

• standard expression of error conditions

• authentication and verification of data integrity

• specific data types and queries to be supported in the
  supported registry services.

Deliverables:

• Requirements document as an Informational RFC. (previously
  submitted)

• First draft of protocol (use) specification. (previously submitted)

• First draft of domain registration administrative directory
  services required schema element specification. (previously submitted)

• Document specifying a new protocol, or the use of an existing one,
  for providing CRISP service (application transport).

• Document specifying required schema elements and queries for domain
  registration administrative directory queries.

• Document specifying required schema elements and queries for
  numbering resources registration administrative directory queries.
