i'm trying to load a json file with some metadata in it

elan.js

var Metadata = function(){ 

  this.files = [];

  this.load = function(){
//console.log('this.load…');
    $.getJSON( 
      "metadata.json", 
      this.store
    )
  };
 
  this.store = function(json){ 
//console.log('Metadata' + show(Metadata));
//console.log('this…' + show(this));
//console.log('this…' + show(json));
console.log('this.store…' + json);
console.log('this.files…' + this.files);
    this.files = json;

  };
  
  this.lookup = function(file_id){
    return _.where(this.files, {file_id: file_id})[0];
  };
  
  this.load();
 
  return { 
    files : this.files
  }
  
}


// what i'm hoping to do with this thing (elsewhere in the app):


}

window.app = (function(){

  var myapp = {};

  myapp.metadata = new Metadata();
  
// then i'd be able to:

  var hil001 =  myapp.lookup('hil001');
  
// now i have the info about hil001…

})()

metadata.json
