You will need to pass the item object and a map of item-keys to entry-keys. This could either be two arrays, an array of tuples or something, or an object. Most simple method I could think of is to change the descriptor object into the entry itself:

function mapPropertyNames(source, dest) {
    for (var prop in dest)
        dest[prop] = source[dest[prop]];
    return dest;
}

// and use it like this:

var map = $.map(data, function(item, i) {
    return mapPropertyNames(item, {key:"something1", value:"something2"});
});
