ODP
The OASIS OpenDocument presentation format, a ZIP-based XML container used natively by LibreOffice Impress, OpenOffice Impress, and other ODF-compliant presentation software.
Extension
.odp
Full name
OpenDocument Presentation
Introduced
OASIS standard approved 1 May 2005; ISO/IEC 26300:2006
Vendor
OASIS OpenDocument (originally derived from OpenOffice.org XML)
What is inside the container
An ODP file is a ZIP archive containing content.xml with all slide, layout, and text-frame data as XML, styles.xml for master slide and formatting definitions, and a Pictures/media folder for embedded images and other assets. As with the rest of the ODF family, the openly published schema means slide text and structure can be extracted directly from the archive without a presentation application.
How to open it
For archives
ODP is a vendor-neutral, ISO/IEC-standardized format that makes a solid long-term archival choice for presentation assets in a DAM. As with PPTX, watch for linked (rather than embedded) media and unembedded fonts, which are the most common causes of a presentation looking different when opened outside its original environment, and verify animation and transition fidelity when converting between ODP and PPTX.
ODP rounds out the three core OpenDocument formats OASIS standardized on 1 May 2005, with ISO/IEC ratification following as ISO/IEC 26300 in 2006. Like ODT and ODS, it grew from the XML format OpenOffice.org Impress had used internally since around 2000, and it became the open, vendor-neutral counterpart to Microsoft’s presentation formats during the same period that produced OOXML’s PPTX.
ODP assets appear in a DAM primarily from organizations standardized on LibreOffice or OpenOffice, or under public-sector open-format requirements. Its ZIP-and-XML structure lets a DAM extract slide text, speaker notes, and embedded media directly for indexing and reuse, mirroring how PPTX is handled. The main interoperability concern for a DAM managing both formats is preserving complex animations and transitions accurately when converting between ODP and PPTX, since those effects aren’t specified identically across the two standards.
- content.xml — all slide, layout, and text-frame data
- styles.xml — master-slide and formatting definitions
- Pictures/ or media folder — embedded images and other assets
- META-INF/manifest.xml — package contents listing
Frequently asked
Can PowerPoint open ODP files stored in a DAM?
Yes, PowerPoint has built-in ODF import/export support, though complex animations and transitions can render differently than in LibreOffice Impress.
Is ODP a common format for presentations in a DAM, or mostly PPTX?
PPTX is more common overall given Microsoft Office's market share, but ODP appears regularly in organizations using LibreOffice/OpenOffice or under open-format mandates.
Can a DAM extract slide text from ODP without a presentation application?
Yes, slide text lives as plain XML in content.xml inside the ZIP archive and can be parsed directly for indexing.
What's the risk when converting ODP to PPTX for a mixed-office-suite DAM?
Text and basic layout convert well, but complex animations, transitions, and certain master-slide formatting can shift, so visual verification of converted files is recommended.
Can embedded videos in an ODP file be extracted directly by a DAM?
Yes, embedded media sits in a Pictures or media folder inside the ZIP archive and can be pulled out without opening Impress.
Does ODP support speaker notes like PPTX does?
Yes, notes are stored as part of each slide's XML structure in content.xml, and a DAM's indexer can include them in full-text search if configured to parse that section.
Is ODP a safe long-term archival format for presentation masters?
Yes, as an ISO/IEC 26300-standardized, vendor-neutral format, it has strong long-term preservation characteristics comparable to PPTX.
Can a DAM generate slide thumbnails for ODP the same way it does for PPTX?
Yes, typically through the same headless LibreOffice rendering pipeline used for other ODF and OOXML presentation formats.
