Media type name: text

Media subtype name: vnd.vri

Required parameters: N/A

Optional parameters: charset: Specifies the character encoding used in the source file. UTF-8 is recommended and expected in most cases.

Encoding considerations: 8bit

Security considerations: This media type represents source code written in the Vir programming language.

The content is textual and does not itself execute automatically. However, when processed by a compiler, interpreter, or other tooling, the code may perform arbitrary actions depending on the implementation and runtime environment.

Applications that accept or process this media type should treat the content as untrusted input and apply appropriate sandboxing or validation when compiling or executing it.

No inherent security mechanisms are defined by this media type. Security considerations therefore depend on the behavior of the compiler, runtime, and execution environment.

Interoperability considerations: This media type represents source code written in the Vir programming language. The content is textual and typically encoded using UTF-8.

Files of this type are intended to be processed by Vir compilers, interpreters, and development tools. The format is platform-independent and may be exchanged between systems without modification as long as a compatible Vir toolchain is available.

No transport or container-specific requirements are imposed by this media type.

Published specification: Vir Programming Language Specification.

Available at:
https://dev.virgori.com/spec

Applications which use this media: This media type is used for source code written in the Vir programming language.

Applications that may use this media type include Vir compilers, interpreters, language servers, build tools, and integrated development environments (IDEs) that support the Vir language.

Examples include the Vir compiler toolchain, development environments, code editors with Vir syntax highlighting, and automated build or analysis systems that process Vir source files.

Fragment identifier considerations: N/A

Restrictions on usage: None.

Additional information:

1. Deprecated alias names for this type: N/A
2. Magic number(s): N/A
3. File extension(s): .vri .sci .svi .vsib
4. Macintosh file type code: N/A
5. Object Identifiers: N/A

General Comments: The Vir programming language is a modern systems and application programming language designed for clarity, explicit control flow, and modular structure.

Files with the ".vir" extension contain source code intended to be processed by Vir compilers and development tools.

This registration is intended to support consistent identification of Vir source files across editors, development environments, version control systems, and network transports.
