Hi all, In the last meeting, we talked about starting a new project around PDF and I agreed to write up a paragraph or two (below and on the wiki:http://www.loc.gov/extranet/wiki/osi/ndiip/ndsa/index.php?title=Standards_and_Best_Practices_Working_Group#Ideas_for_New_Work). Can we put this on the agenda for the next meeting? Meanwhile, interested parties can think if this is something they'd like to be actively involved in and what role they'd like to play. Thanks - Kate Murray **************** One of the great strengths of PDF, including the recent PDF/A-3 standard, is its ability to contain a variety of sometimes complex digital objects within a single file. Long term preservation of these files, however, can be problematic because current digital preservation tools are not able to consistently identify the existence of the embedded content nor identify its format. The NDSA Standards sub group is interested in exploring the boundaries of applicability for PDF in preservation environments, especially as a carrier of complex formats such as audio, video and geospatial information. The interest in this project grew out of a Signal blog post on PDF/A-3 by Butch Lazorchak (LOC) about embedded files in PDF/A (http://blogs.loc.gov/digitalpreservation/2012/11/all-in-embedded-files-in-pdfa/) as well as discussions between NARA and depositing agencies who are starting to use PDF/A-3 as a de facto normalization wrapper format to contain many media types including audio and video. Caroline Arms (LOC) has already produced a helpful background document to kick start this work. ************** Kate Murray Digitization Process Development Specialist Digitization Planning Branch US National Archives and Records Administration (NARA) 301-837-2924 [log in to unmask] ############################ To unsubscribe from the NDSA-STANDARDS list: write to: mailto:[log in to unmask] or click the following link: http://list.digitalpreservation.gov/scripts/wa-DIGITAL.exe?SUBED1=NDSA-STANDARDS&A=1
