SHA-256 of the profile bytes, base64 encoded. Two profiles with the same hash have the same content.
name
string
The ICC desc tag of the profile. Empty when the profile carries no description, and until the engine opens the profile. A profile that you assign opens at once. After a scene or archive load, a profile opens when a conversion needs it, or when loadColorProfiles runs.
uri
string
The URI the document names the profile by, for setCMYKProfile. An archive save and load rewrites it.
