veraPDF (PDF/A validation)
veraPDF is an open source conformance checker for PDF/A files. It is designed to help archives and libraries check that their PDF/A collections conform to the appropriate ISO 19005 archiving standard specification. Ensuring files adhere to the standard is an important step towards providing long term preservation for and access to digital assets. veraPDF is the first complete open source PDF/A validator, covering all parts of the PDF/A standards. It has been developed with the support of the PDF industry who have helped to answer questions and resolve ambiguities arising when interpreting the ISO specifications.
Led by the Open Preservation Foundation and the PDF Association, veraPDF was funded by the EU PREFORMA (PREservation FORMAts for culture information / e-archives) project from June 2014 to July 2017. PREFORMA’s aim is to empower cultural heritage institutions to gain control over the technical properties of preservation files. It commissioned three conformance checkers (document, image and audio-visual).
veraPDF is now maintained by the OPF as part of the open source digital preservation reference toolset.
veraPDF is open source meaning it is free to download, use and modify. However, it is not free of costs to host, maintain, support or develop the software. Currently, only members of the Open Preservation Foundation support veraPDF as part of their membership fees.
