The Digital Preservation Coalition (DPC) has made the next three Technology Watch Guidance Notes in the new ‘Data Type’ series available on general release today. The topics covered in the set are: audio file formats, moving images and raster images.

Authored by staff at Artefactual Systems in collaboration with the DPC and developed in conjunction with the UK Nuclear Decommissioning Authority, each of the Guidance Notes in the Data Type series is designed to provide a primer on the current state of community knowledge about types of data commonly encountered by those seeking to preserve digital holdings.

"One of the great benefits I saw from the project was how we learned from each other as we worked through each particular topic," says Kelly Stewart, Chief Archivist at Artefactual and co-author of the notes.

"There were many places where we could see common threads throughout all the topics but many other areas that diverged entirely.  I am proud of the work that was produced and the folks who produced them.  I hope these notes will help those who care for some part of the world's cultural memory to ensure that the evidence of the past is cared for now and in the future."
