OpenDocument Presentation (ODP) is an XML-based file format for presentation documents, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). This open-standard format is primarily used by productivity suites like LibreOffice and Apache OpenOffice to create slideshows containing text, images, and multimedia. Although generally considered safe, these compressed archives can contain macros or external references, necessitating standard security precautions when opening files from unverified or anonymous third-party sources.

}
Go
