  doi: munk.select("#ddDoi")
    .bind(function(a) { return a.href})
    .bind(function(a) { return a.split("org/")[1]}),

  attachments: [munk.select(".icon-pdf a").href()]
}

/* .bind(fn) composes fn with the previous returned value
fn is additionally called with the values of previous returned values as arguments
(munk.bind(function(){return 1}).bind(function(){return 2}).bind(function(a,b){return [a,b]}))() evaluates to [2,1]

.bind(function(a) {return a.href}) will be common enough to be sugared to .attr("href") or .href()
.select is sugar for .bind(function(a){return Sizzle(a)})
