OpenDocument Presentation Template (.otp)
An OTP (OpenDocument Presentation Template) file is a presentation template format used in applications adhering to the OASIS OpenDocument standard, such as OpenOffice Impress. It contains slides with text, images, shapes, multimedia content, and transition effects, enabling users to create new presentations quickly based on predefined styles. The format, based on XML, ensures consistency and compatibility across different platforms. OTP files are similar to Microsoft PowerPoint's POT and POTX templates.
