Media type name: application

Media subtype name: vnd.sri

Required parameters: N/A

Optional parameters: N/A

Encoding considerations: binary

Vir executable files are binary programs generated by the Vir compiler. The format may contain arbitrary binary data, including NUL octets and unrestricted byte sequences. Therefore the encoding is binary.

Security considerations: This media type represents executable binary programs compiled from the Vir programming language. As with any executable binary, executing untrusted files may pose security risks. Systems should validate file origin and integrity before execution.

Interoperability considerations: Vir executable files may depend on the target operating system and processor architecture (e.g., ARM64, x86_64). Compatibility is determined by the ABI and runtime expectations of the Vir compiler and execution environment. Systems that do not implement the Vir runtime or ABI may not be able to execute these binaries.
