OpenDocument

OpenDocument, also known as Open Document Format for Office Applications or ODF, is a family of file formats designed to be used by word processors, spreadsheet applications, and other office applications. It is (more or less?) the successor to OpenOffice.org XML. These formats were developed by a group called OASIS, so they are sometimes referred to as "OASIS format" or "OASIS Open Document Format".

Identification
In most cases, OpenDocument files begin with the ASCII string " ", have " " at offset 30, and " " at offset 38.
