1. Introduction
This document specifies a file format for the storage of unavailable
domain names and related details for a top level domain (TLD) name
registry, designed to facilitate interoperability and reusability
among domain name registries and registrars.
The increased number of domain name registries and registrars, the
greater number of reasons for domain names not being available, and
to make accommodations for possible real-time communications issues
between registries and registrars has driven the need for this
standard sharable file.
1.1. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
2. General File Format Elements
File format will be a comma separated values (CSV) file and MUST use
the US-ASCII character set. See informational RFC 4180 and RFC 7111
for details on the CSV file format.
Filename has two forms depending on content. For a file containing
only a list of unavailable domain names in one Top Level Domain (TLD)
the filename MUST be <TLD>-unavailablenames-<YYYY-MM-DDThhmmss>.csv.
For a file containing a list of unavailable domain names in multiple
Top Level Domains (TLDs) the filename MUST be unavailablenames-<YYYY-
MM-DDThhmmss>.csv. For an IDN TLD <TLD> MUST be ace-encoded (i.e. in
the "xn--" format). <YYYY-MM-DDThhmmss> MUST be the date and time
(in UTC) the file was created indicating that all the names in the
file were unavailable on that date at the time the file was created.

Internet-Draft Unavailable Domains June 2016
The first row MUST be the column headings: TLD, Domain Name, Status.
The remaining rows will contain the data (all unavailable names) from
the registry in the following structure: <TLD>, <Domain Name>,
<Status>. Where <TLD> is the TLD of the domain name, <Domain Name>
is the string of characters that represent the unavailable name, and
<Status> is one of four values (REGISTERED, REGISTRY RESERVED, POLICY
RESERVED, IDN VARIANT RESERVED). If the <TLD> and/or <Domain Name>
is an IDN it MUST be ace-encoded (i.e. in the "xn--" format).
All domain name labels that are not available for registration in the
SRS, for any reason, to the registrar channel MUST be included in
this file.
3. Examples
3.1. Single TLD File Example
Example of a file that contains unavailable domain names from a
single TLD.
FileName: example-unavailablenames-2016-05-01T010000.csv
TLD,Domain Name,Status
example,e.example,REGISTRY RESERVED
example,ex.example,POLICY RESERVED
example,example.example,REGISTERED
example,xn--4gqvdy3r.example,REGISTERED
3.2. Multiple TLDs File Example
Example of a file that contains unavailable domain names from
multiple TLDs.
FileName: unavailablenames-2016-05-01T010000.csv
TLD,Domain Name,Status
example,e.example,REGISTRY RESERVED
test,ex.test,POLICY RESERVED
another,xn--4gqvdy3r.another,REGISTERED
4. Security Considerations
The file format described in this document does not provide any
security services.
