File Extension ODP
File extension ODP is the default suffix generated by OpenOffice.org's Impress application. Impress is a presentation application similar to Microsoft's PowerPoint whose files are made up of slides that may contain images, texts, graphs and audio files essential for use when presenting reports. It can run on cross-platform environment making it suitable for installation on systems implementing different standards. This includes machines running with Windows, BSD, Mac, Solaris and Linux.
Furthermore, an added feature of Impress which makes it advantageous among other presentation application is its support to convert native ODP files into SWF files (commonly referred as flash files) that can be embedded on web based applications. Distributed under GNU Lesser General Public License as open source, the application is free for anyone to download.
The OpenOffice project was initiated by Sun Microsystems as an answer to the ever rising demand for free office applications. Today, there are several applications that have complied with the OpenDocument format. These include KOffice, NeoOffice, SoftMaker Office and Zoho. As an open source, any user can modify the source code to enhance the application and later on publish their modified copies for public consumption.
ODP is among the children of the OpenDocument format which includes ODT for word processing, ODS for spreadsheets, ODB for databases, ODG for graphics, and ODF for mathematical expressions. The format's specifications was fathered by Sun Microsystems, however, the actual standard was enhanced and developed by Organization for the Advancement of Structured Information Standards (OASIS) through their Open Office File extension XML Technical Committee division.
Despite the popularity of the application, some big names in the software industry have yet to develop applications that can render ODP files. These companies include Google whose online storage facility, Google Documents, caters other OpenDocument formats including ODT and ODS, but not ODP.
In addition, ODP files can be opened and edited on applications whose standards are in conformity to the OpenDocument format. The Impress application that comes with the StarOffice from Sun Microsystems can also render ODP files similar to how OpenOffice's Impress does. The two applications may sound confusing, but these are actually different programs using similar standards.
Lately, Microsoft adopted the OpenDocument format on their newly released office applications, Microsoft Office 2007 Service Pack 2. This means that documents created through OpenDocument conformant applications, including OpenOffice's Impress, can now be accessed and viewed through Microsoft Office applications in addition to their support of their own proprietary format.
