The Planets Digital Preservation Project was a 4-year EU-funded research project aimed at increasing Europe's ability to ensure long-term access to cultural and scientific digital content. The project sought to improve decision-making around long-term digital preservation, ensure access to valued digital content over time, control preservation costs through automation and scalable infrastructure, and promote adoption of preservation services and tools across user communities and commercial markets. Bringing together archives, libraries, researchers and technology companies, the project built practical preservation solutions by integrating existing expertise, designs, and tools.
