pfo_logo_ptrait-300x217PREFORMA, PREservation FORMAts for culture information/e-archives, is a Pre-Commercial Procurement project started on January 1st, 2014, and co-funded by the European Commission under its FP7-ICT Programme. The main objective of the project is to give memory institutions full control of the process of the conformity tests of files to be created, migrated and ingested into archives, through the development of a set of tools which enable this process to happen within an iteration that is under full control of the institutions.

VeraPDF: An industry-supported PDF/A conformance checker

logo_veraPDFA unique collaboration, the VeraPDF Consortium brings together an end user community and a software industry rooted in the principle of interoperability based on ISO standardized technology. The VeraPDF consortium will generate an authoritative corpora of test files and execute the development of a purpose built implementation checker, associated policy checker optimized for the use of digital preservationists, and metadata fixer software. The VeraPDF consortium’s end product will be an industry-supported conformance checking software for PDF/A-1, PDF/A-2 and PDF/A-3 under GPLv3 or later and MPLv2 or later open source licenses together with a substantial and enthusiastic community supporting and extending the model.

DPF Manager: Digital preservation formats manager

logo_DPF_manager-300x155DPF Manager is an open source modular TIFF conformance checker that is extremely easy to use, to integrate with existing and new projects, and to deploy in a multitude of different scenarios. It is designed to help archivists and digital content producers ensure that TIFF files are fit for long term preservation, and is able to automatically suggest improvements and correct preservation issues. The team developing it has decades of experience working with image formats and digital preservation, and has leveraged the support of 60+ memory institutions to draft a new ISO standard proposal (TIFF/A) specifically designed for long term preservation of still-images. An open source community will be created and grown through the project lifetime to ensure its continuous development and success. Additional commercial services will be offered to make DPF Manager self-sustainable and increase its adoption. For more information visit:

MediaConch: Conformance checking for audiovisual files

ms-icon-310x310-300x300MediaConch (CONformance CHecking for audiovisual files) is an extensible, open source software project consisting of an implementation checker, policy checker, reporter and fixer that targets preservation-level audiovisual files (specifically Matroska, Linear Pulse Code Modulation (LPCM) and FF Video Codec 1 (FFV1)) for use in memory institutions, providing detailed and batch-level conformance checking via an adaptable and flexible application program interface accessible by the command line, a graphical user interface, or a web-based shell. MediaConch is currently being developed by the MediaArea team, notable for the creation of open source media checker software, MediaInfo. Furthermore, the MediaArea team is dedicated to the further development of the standardization of the Matroska and FFV1 formats to ensure their longevity as a recommended digital preservation file format.
