<p>Cfle: /* PDF/A-3 Use Case Scenarios */</p> <hr /> <div>Back to [[NDSA:Standards_and_Best_Practices_Working_Group | Standards Working Group Main Page]]<br /> <br /> ==Title of Activity or Project==<br /> NDSA PDF/A-3 Scoping Project<br /> <br /> ==One Sentence Description:==<br /> NDSA PDF/A-3 Scoping Project working group members will research the pros and cons of using the PDF/A-3 standard as an all-purpose wrapper for various digital asset/media types including: textual, audio, video, photo, and GIS data.<br /> <br /> ==Statement of the Problem and Goals for Addressing the Problem:==<br /> It is unclear whether PDF/A-3, which was designed to accommodate supplementary media files for text documents, is appropriate as a de facto normalization wrapper format for all media types. The goal is to develop guidelines for the appropriate use of PDF/A-3 with respect to different media types that includes both detailed technical information and a practical quick reference guide for end-users.<br /> <br /> ==Strategic Value of Activity:==<br /> * Improve understanding of best practices for using PDF/A-3 in digital preservation activities<br /> * Enhance consistency and improve long-term viability of digitally preserved content <br /> * Provide guidance to those considering PDF/A-3 as a long-term archiving format<br /> <br /> ==Required Resources:==<br /> * Time of working group members<br /> * Publishing venue(s)<br /> * Communication channels<br /> <br /> ==Roadmap:==<br /> # Hold regular working group conference calls (monthly, between NDSA Standards WG calls) <br /> # Draft document and review<br /> # Invite broader NDSA member feedback<br /> # Publish document (digitalpreservation.gov, others?)<br /> <br /> ==Dissemination of Knowledge:==<br /> * Publish report on digitalpreservation.gov<br /> * Write a blog post<br /> * Announce on NDSA member organization communication channels<br /> * Present at conferences that members (and non-members?) are attending<br /> <br /> ==Signifiers of Success and Outcomes:==<br /> * Completed guidelines document published on digitalpreservation.gov<br /> * Guidelines document referenced on related Wikipedia pages<br /> * Guidelines in use or recommended by NDSA participating organizations or others<br /> * Publication at other conferences/other journals<br /> <br /> ==Questions to Ask and Answer==<br /> *Talk about background (what is pdf/a-3 and how is it different from earlier versions of PDF/A)<br /> *Iterate categories of materials/use cases/concrete examples where it makes sense to use A-3 and other categories where it doesn't make sense. Example: if you're sending a video file don't put it in a PDF! If you had a certain kind of a journal article that had a static version of the spreadsheet in the doc but a malleable version embedded perhaps that argues for it. <br /> *Risks to the format (scenarios in why this might be bad and why)<br /> *Possibilities of the format (scenarios in why this might be good and why)<br /> *Have list of defined terms in our document. How do these relate to the terms in the ISO spec. Leverage NDSA Levels of Preservation glossary. Link to glossary.<br /> <br /> ==PDF/A-3 Use Case Scenarios==<br /> Add them here! We can create a separate page as necessary. <br /> ----<br /> Example: Federal agency with a document management system puts an MPEG video file (and nothing else) into a PDF/A-3 file to store and then, later, to submit as an SIP to NARA for long-term management.<br /> <br /> Example: Publisher has a text-only article and puts it into a PDF/A-3 file, even though, in the past, the publisher used PDF/A-2. The article is then sent to library where it will be preserved for the long term.<br /> <br /> Example: Publisher has an article that includes a complicated table, &quot;frozen&quot; in place, and puts it into a PDF/A-3 file, along with the Excel file from which the table was generated, in order to make it easier for a future researcher to have a malleable version of the table for use when writing another article on the same subject.<br /> <br /> ==Members==<br /> *Carl Flei<br /> *Chris<br /> *Caroline<br /> <br /> ==Calls and Notes==<br /> Next call: Tuesday Jan. 22, 2013, 2:00 P.M.<br /> <br /> ==Background Materials==<br /> <br /> *[http://www.digitalpreservation.gov:8081/formats/fdd/fdd000360.shtml Library of Congress Sustainability of Digital Formats PDF/A-3 site]<br /> *Blog Post<br /> *Ithaka article<br /> *Caroline's document <br /> *In future set up calls with Steve Levinson (U.S. Courts) and Leonard Rosenthal (Adobe)</div>
