The OTP (OpenDocument Presentation Template) file format is a standardized template format used for creating presentations within the OpenDocument family of file formats, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). It is primarily supported by open-source office suites like LibreOffice and Apache OpenOffice, as well as other applications that adhere to the OpenDocument standard. The format is based on XML and supports advanced features such as embedded multimedia, customizable slide layouts, and compatibility with other presentation formats like PPT and PPTX through conversion tools.
