Update a sample's meta field properties

Use this call to update a meta field's value, or linked files/samples.

In case of a meta field with selectable value - data types CHECKBOX, COMBO and RADIO - make sure that you only specify the values that are listed in the sample type's optionValues property. In case of multiple selected values, separate each value with a comma. If you want to unselect all options supply an empty string to the value property.
