Open source and web based html5 document viewer [closed]

Is there a free web based html5 document viewer?

What is HTML5 viewer?

An HTML5 document viewer is a document and image viewing solution that allows users to easily view and collaborate on multiple file types from any desktop or mobile device within a browser.

How do I use ViewerJS?

For initiating ViewerJS we point the browser to the viewer which (if you followed the instructions) resides at /ViewerJS/index. html. We only need to write down /ViewerJS/, the browser will understand the rest. The next thing we need to do is tell the browser the location of the actual file we want to show.

OpenOffice (or LibreOffice) can be run as a service that let's you stream documents to it and it can return other formats. PDF and Flash are definitely supported. I think it can also do HTML. It's not a full viewer -- just the HTML -- you would have to figure out how you want to display it on a page.

You could take a look at the DocumentCloud project which has a bunch of components including an HTML5 Open Source Document viewer - NYtimes Document viewer - hosted on git (Apache license)
