It would be great to have a website where we can direct people who ask what Tika can do for [filetype] without needing them to actually download Tika.
Some initial work to do that is here.
I'm far from a design guru, but I imagine the site as having a form where you can upload a file at the top, checkboxes for if you want metadata, content, or both, and a submit button. The request should be sent with AJAX and the result should populate a div.
One issue with AJAX requests is that Tika Server doesn't currently allow Cross-Origin-Resource-Sharing (CORS). So, we either need to maintain a slightly updated tika-server, or update the server to allow configuration.
