This is a proof-of-concept application that implements access to the VAMDC infrastructure in JavaScript, thereby allowing to run an application in the users’ webbrowser. The example uses the popular Query library to let the user select an element and a wavelength range. It then formulates the query to a data node, asks it for the amout of data available and presents this to the user. In a second step, the user can hand the data-URL to a VAMDC Processor service and plot the result that it gets back. Alternatively, one can also chose to download the data from the node into the browser and do a simple tabular display of it.

Since this application consists of only a HTML and a JavaScript file, it can easily be modified for different purposes and hosted on any webserver that serves static files. The source code is available at https://github.com/VAMDC/jQueryPortal
