OpenDocument Viewer is a cross-platform viewer for OpenDocument files.
Have you ever had trouble opening a document that someone sent you? Have you ever bought a copy of MS Office that you didn't want because you have to read documents that only work with that version of MS Office? Have you ever wondered why there is so little choice in office software?
What you are seeing is vendor lock-in. It happens because your documents are written in a secret format that only one software maker knows. This prevents competitors from making products that can read and write those files well. In short, it reduces your choices down to one.
Vendor lock-in is the enemy of competition. It short-circuits the market forces that would normally give you better products at a lower cost. OpenDocument is a way out of vendor lock-in for office software.
What if you could send a file to anyone and know that they can read it?
What if you could buy any product you want and know that you can still communicate with your customers?
This is the promise of the OpenDocument Format (ODF), an open, XML-based file format for office documents. It includes text documents, spreadsheets, drawings, presentations and more.
OpenDocument is freely available for any software maker to use and implement and does not favour any vendor over all the others.
