1. Introduction

The Structured Query Language (SQL) has been in use for over 30 years
with various types of database technologies. However, there is no
current media type registered for SQL. Therefore, this document
seeks to formally register the application/sql media type to be used
for SQL with IANA.

2. 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 [RFC2119] when they
appear in ALL CAPS. These words may also appear in this document in
lower case
lowercase as plain English words, prose, absent their of the normative meanings. meanings
mentioned above.

3. Media Type Registration Application

This section provides the media type registration application for
this media type (see [RFC6838], Section 5.6)

Type name: application

Subtype name: sql

Required parameters: N/A

Optional parameters:

"charset" - -- indicates the character set to be used. When not
specified, a default value MUST NOT be assumed without inspection
of the content.

Implementators

Implementors should be aware that SQL may carry character set
information in-band. In such cases, the "charset" parameter MUST
NOT be used in order to avoid conflict. In cases, cases where no
character set information is supplied in-band, and the character
set is known, implementors SHOULD use the "charset" parameter. If
no in-band or out-of-band character set information is available,
implementors MUST NOT specify the "charset" parameter.

Encoding considerations:

If the "charset" parameter is used, the corresponding 7-bit, 8-bit
8-bit, or binary encoding may be used. If the "charset" parameter
is not used, binary encoding may be required.

Security considerations:

Being that SQL is a full fledged full-fledged programming language and may
include embedded source code for other programming languages,
there is a risk of it being used to transfer malware, viruses viruses, and
other malicious payloads. Implementors and users are encouraged
only to exchange SQL files among trusted parties and utilize all
available security measures measures, such as restricted access, virus
scanners, etc. etc., to minimize risk.

Implementors should be aware that guessing character sets,
encodings, and possible conflicts between in-band and out-of-band
character set information may lead to the similar security issues
as described above.

Implementors should also be aware that SQL does not provide or
guarantee any sort of confidentiality and integrity checking, and
SQL files can expose account information or private information
about database structure and contents. It is therefore important
for applications to provide confidentiality and protection against
modification by malicious third parties while in transit.

Interoperability considerations:

While a single standard exists ([ISO.9075.2011]), vendor
implementations of the standard vary significantly. Implementors
and users should make sure that the exchanged SQL files match to
the specific database/tool and version that they are using.

Published specification:

The most recent specification of SQL is available in
[ISO.9075.2011].

Applications that use this media type:

Databases and related tools

Fragment identifier considerations: N/A

Additional information:

Deprecated alias names for this type: N/A

Magic number(s): N/A

File extension(s): sql

Macintosh File Type Code(s): N/A

Person & email address to contact for further information:

Intended usage: COMMON

Restrictions on usage: N/A

Author: IESG

Change controller: IESG

Provisional registration? (standards tree only): N/A

4. IANA Considerations

IANA is asked to register the media type application/sql has registered "application/sql" in the
Standards standards tree of the
"Application Media Types" registry, using the application provided in
Section 3 of this document.

5. Security Considerations

See the Security Considerations item in the registration template in
Section 3, above.

6. Acknowledgments
