Open not download

Newbie here. Is it possible for OwnCloud to serve up a collection of PDF documents, but have them open in the browser rather than download to the desktop? We need users to view in the browser as we use a browser based annotation tool for discussion - . In short, we need users to discover and find documents but not download them - just view in their browser.

If you want no download you would need to build an ownCloud app which runs this code. You could likely use the current pdf viewer app as a starting point. Disallow download would be a different beast, but I guess thats not what you are looking for?
