ETERNAL RDC-Arq Digital Repository in Brazil awarded ISO 16363 certification

PTAB can announce that the ETERNAL RDC-Arq Digital Repository has been awarded global ISO 16363 certification.

After a great deal of preparatory work by the staff of CIASC and OAIS Cloud, which are partners in the archive, with the PTAB Audit Team, the Stage 2 audit took place in January 2024. This followed the extensive Stage 1 of the audit process. The full audit process is described in the overview.

Pre-assessment service available for ISO 16363

Pre-assessment is a way for you to find out quickly and easily what the weaknesses of your repository are in terms of digital preservation. This is essentially an ISO 16363 Stage 1 audit, to examine your documentation. There is no commitment to proceed any further with a full audit but it should lead to improvements in your ability to preserve your valuable digital holdings no matter whether you carry on to the full audit or not.

The application form is available here.

Surprising results from OAIS Quiz

The digital world is getting more complex and interrelated, and we are all dependent on it.

Those responsible for preserving our digital capital into the future, right now have mostly simple PDFs, audio, video and images. But soon the complex and interrelated objects  will be coming their way. Even for something seemingly as simple as a spreadsheet one must know not just the format but also what the columns mean and what their units are. Centigrade or Fahrenheit, meters, millimeters or inches – makes a big difference.

The OAIS Reference Model (ISO 14721) is one of the most important standards for digital preservation, but the average that people scored in a quiz on OAIS which I set up was 66%, which I found surprising.

Take the quiz yourself to test your knowledge of OAIS and the fundamentals of digital preservation, to see if you are ready for the future.

You can improve your knowledge by taking our OAIS course.

If you want to prove your archive is trustworthy then take the course on ISO 16363, then apply for certification. Which would you trust to look after your valuable digital assets, an  archive ISO certified by independent auditors, or one which the staff say is OK?

Both courses are live on-line with one of the authors of these standards, like myself, and can be arranged to suit your timetable.

We have been trialing this way of providing the courses, at a reduced price. The cost will increase after 1st Jan 2020 but we will honour the reduced price for any course ordered before that date.

Don’t risk losing your valuable digital data, take action now.

On-line personal training

Because of demand from countries around the world for an online course PTAB would like to announce, in the first instance, online courses for a 4-day High Level Course on ISO 16363 (the outline is here, which also covers OAIS) and a 2-day course solely on OAIS for beginners. Additional courses are also planned for Data Management Planning and Digital Signature preservation (particularly for legal and government legislative documents).

The dates can be flexible to suit the attendees as can the way in which the course is delivered, for example full days or half days, run on consecutive days or spread over over one or more weeks.

USGPO receives ISO 16363 certification

PTAB first in the world to be accredited for ISO 16363 audit and certification

Much of our lives and our futures depend on digital information yet the “father of the internet” Vint Cerf worries about the coming “digital dark age”. How can we know who can be trusted with our digital future?

Now there is a way to do it in the same way we know which systems we can trust for food, environment, energy, namely through ISO certification by ISO accredited audit organisations. The standard in this case is ISO 16363, based on ISO 14721 which is better known as OAIS, the fundamental standard of digital preservation used throughout the world.

The first organisation in the world to receive accreditation for ISO 16363 for Trustworthy Digital Repositories is the Primary Trustworthy Digital Repository Authorisation Body Ltd (PTAB), based in Dorset, UK.  PTAB is now listed in the Register of Certification Bodies of National Accreditation Board for Certification Bodies (NABCB) under registration number TD 001 after the extensive accreditation process.

As a result, PTAB is authorized to audit digital repositories worldwide and, when appropriate, certify that they are trustworthy.

The PTAB international team members, each recognized for their expertise in digital preservation, authored ISO 16363 and many also authored ISO 14721 (OAIS), the fundamental standard for digital preservation.

For more information visit the website at, email or phone Dr David Giaretta, PTAB Director, on +447770326304.

PTAB’s accreditation (Accreditation number TD 001) can be confirmed at the NABCB website.
