BOAWP registry of commands, headers, and datatypes

This registry exists to ensure proper cooperation between various BOAWP implementations.

The default datatypes and headers apply to every protocol, and are extended in the documents listed below.



Each protocol contains a table which maps the name of the init, datatype, or header to various representations (decimal, hex, etc).

When implementing BOAWP, it is important to use the exact same decimal or hex values assigned in this registry.

The default init, datatypes, and header listed below must be used in addition to the protocol-specific assigned values.

Default init

Name Hex UTF-8 BOAWP Version Description
BOA v01 0x424F4130310A "BOA01\n" 1 BOAWP protocol init string

Default datatypes

null 110 0x6E "n" 1
true 116 0x74 "t" 1
false 102 0x66 "f" 1
integer 105 0x69 "i" 1 signed big-endian integer (2s complement)
string 115 0x73 "s" 1 UTF-8 string
