Define schema for scalar parameters

[eirikblekesaune]

The Jamoma style schema would IMO be too implementation specific. E.g. 'value/default' points to 'default' being an attribute of 'value', which in the context of defining a scalar value is redundant.

What keys do you find are generic, and which a more implementation specific?

Here is one suggestion:

{
type: "decimal",
value: 0.1, //the current value
default: 0.5, // to which value the parameter is reset to
range: {
    bounds: [0.0, 1.0],
    clipmode: "both" // "both" | "none" | "high" | "low"
    },
filterRepetitions: 1,
stepsize: 0.01,
description: "This is a description of my parameter",
}

This is the schema for a scalar decimal value. In addition one can add implementation specific keys. The resulting, full-fledged description would then be (when communicating between my system and Jamoma):

{
volume: {
type: "decimal",
value: 0.1, //the current value
default: 0.5, // to which value the parameter is reset to
range: {
    bounds: [0.0, 1.0],
    clipmode: "both" // "both" | "none" | "high" | "low"
    },
filterRepetitions: 1,
stepsize: 0.01,
description: "This is a description of my parameter",
dataspace: {
    type: "gain",
    uinit: "linear"
    },
priority: 0,
tag: "vol",
}
}
