Recording and slides from veraPDF webinar published

The PREFORMA project ran a webinar series throughout September. The final webinar focused on veraPDF.

Overview

The PREFORMA project’s prototyping phase finishes at the end of 2016. The veraPDF consortium will be producing a v1.0 release candidate of the software library and applications in December 2016.

This webinar demonstrates the current state of veraPDF development and presents the consortium’s plans for 2017. Webinar attendees are shown:

  • the consortium’s current development priorities, i.e. what we’re working on;
  • the veraPDF software development plan for the 2016 v1.0 release;
  • how they help to improve veraPDF software through testing;
  • a demonstration of the software used in some simple, but typical testing scenarios; and
  • an outline of the consortium’s plans for 2017.

The presentations are aimed at non-technical veraPDF users and will benefit anyone wishing to make veraPDF validation part of their digital preservation processes.

PREFORMA Experience Workshop – Improving long-term digital preservation

Following the successful Open Source Workshop, organised in Stockholm in April this year, the PREFORMA project invites all the members of the digital preservation community to attend the Experience Workshop – Improving long-term digital preservation, which will be held in Berlin on November 23, 2016.

The aim of the workshop is to demonstrate the use of the conformance checkers for file-formats developed in the project, involve memory institutions outside the PREFORMA consortium in testing, using and further developing the software, and share the experience gained by PREFORMA memory institutions working with developers under R&D service agreements.

Hosted at the Kulturforum in Berlin, the event will feature keynote presentations by representatives from the European Commission on the opportunities offered by the Pre-Commercial Procurement instrument, talks by international experts in digital preservation on the importance of checking the conformance of the digital files against the standard specifications, live demonstrations of the software developed by the three suppliers working in the project (veraPDF, Easy Innova, MediaArea) and an informal networking event where the attendees can share experiences, meet the PREFORMA developers and learn about the tools.

This event is aimed at anyone interested in digital preservation and cultural heritage: memory institutions or other cultural heritage organisations involved in (or planning) digital preservation initiatives; developers who want to contribute code to the PREFORMA tools; standardisation bodies maintaining the technical specifications of preservation file formats; any other person interested in cooperating with us in defining open digital preservation standards.

The workshop will be co-located with Europeana Space final conference, the third edition of the Networking Session for EC projects in the cultural heritage field and the meeting of the German Working Group on PCP and PPI (Pre-Commercial Procurement and Public Procurement of Innovative solutions).

Register before 16 November 2016

http://experienceworkshop.preforma-project.eu/registration/
Participation in the event is free of charge.
