Hamburg Kennedy Photographs (HKP) is the preeminent private art advisory service that emphasizes a highly-individualized, client-oriented approach to art investment. They are based in New York City. The gallery's website is built using the open-source content management system Drupal, as the framework for the site. The site makes use of references that link photographs to its artist and any collections where HKP wants to display the art. This flexibile structure allows for content to be created once and reused in many different ways. Each piece of art of the site has a link to enquiry about it. When a visitor clicks on the link, they are taken to a form that is automatically filled out with the details of the piece they are interested. This form sends all the information the HKP staff need to follow up with a potential customer.
