Javascript Annotator

The Javascript Annotator allows annotations to be generated by executing a program or expression written in JavaScript.

The layer manager has two modes of operation:

Label Mapping

new annotation labels are generated from a small JavaScript expression operating on the label from a given source layer.

Full Script

a full script is given the whole annotation graph, which it can traverse, process, and add annotations to.

Configuration parameters are encoded as a JSON string, e.g.

{
    "labelMapping":"true",
    "sourceLayerId":"word",
    "destinationLayerId":"js",
    "transcriptLanguageLayerId":"transcript_language",
    "phraseLanguageLayerId":"language",
    "language":"en.*",
    "script":"length"
    }

The parameters are:

labelMapping

"true" for Label Mapping mode. Otherwise the mode is assumed to be Full Script.

script

The JavaScript script to execute.
In Full Script mode, this is the complete script, and no other parameters are required.
In Label Mapping mode, this is the expression to apply to the source annotation label, and the following parameters also apply:

sourceLayerId

Input layer from which annotations are selected.

destinationLayerId

Output layer on which new annotations are added.

transcriptLanguageLayerId

Transcript attribute for overall language.

phraseLanguageLayerId

Layer annotating phrases in a different language.

language

Regular expression for the ISO language codes of the languages to target, or blank for all.
