Johan van der Knijff, the National Library of the Netherlands, presented his views on ‘PDF/A-3 for preservation’ based on notes on embedded files and JPEG2000. The presentation was given at DPC briefing (http://bit.ly/1b487mD) which introduced and reviewed recent developments with the PDF / A standard, with particular emphasis on PDF/A version 3 published in October 2012. The meeting took place in Leeds on 13 March 2013.

Notes on embedded files and JPEG 2000

Part 1: Embedded files
PDF/A-3: embedding of any file (type)

Key point:
Use of “embedded files” really means
“embedded file streams” = specific data
structure in PDF!

File specification dictionary
31 0 obj
<</Type /Filespec /F (mysvg.svg) /EF <</F 32 0 R>> >>
endobj

File specification dictionary
31 0 obj
<</Type /Filespec /F (mysvg.svg) /EF <</F 32 0 R>> >>
endobj
EF key
points to embedded file
stream

Embedded file stream
32 0 obj
<</Type /EmbeddedFile /Subtype /image#2Fsvg+xml /Length 72>>
stream
…SVG Data…
endstream
endobj

File attachments not meant to be rendered by
viewer

File attachment annotation
EmbeddedFiles entry in name dictionary
PDF/A-3

Rendition actions
Screen annotations
PDF/A-3

Not based on “embedded file stream”, but on
“Image XObject” data structure (allows
limited set of pre-defined formats)
What about inline images?

No impact on content that is meant to be
rendered by PDF viewer
But PDF/A-3’s may contain file of any possible
format as an attachment
Embedded files wrap-up:

Part 2: JPEG 2000
Supported since PDF/A-2

Image XObject
1614 0 obj
<</Subtype/Image/Width 615/Height 978/ColorSpace/DeviceRGB
/BitsPerComponent 8/Interpolate true/Length 5278
/Filter/JPXDecode>>
stream
… Image data …
::
::
endstream
endobj

ISO 19005-2 (PDF/A-2):
JPEG 2000 support based on subset of JPEG
2000 Part 2 (JPX baseline)
Only Part 1 of the standard (JP2) commonly
used for archival applications!

JP2 vs JPX
JP2
JPX
JPEG 2000 Part 1:
Basic still image format
JPEG 2000 Part 2:
= JP2 + assorted
advanced stuff …

Fragmented codestreams
Allowed in JPX Baseline!

OS PDF viewers – JPEG 2000 libraries
Ghostscript: OpenJPEG or JasPer
Evince: OpenJPEG
Mupdf: OpenJPEG
Firefox PDF viewer: built-in decoder
 None of these libraries support fragmented
codestreams!

Is it really a problem?
Fragmented codestreams extremely rare
But why is this feature even allowed in a long-
term archival format?
OS support of JPEG 2000 in general remains
problematic

Mail Merge ( http://www.msoutlooktools.com/category/mail-merge.html) is a utility of MS office software that provides to spread a single message numbers of persons by their name. One can share personalize emails data in groups at once. It is simplest way to communicate numbers of people with their own information. Simplest features of Mail Merge software are: • Spread single letter, wedding card , greeting card etc to multiple people • Available in all versions of MS Office • Get release from multiple documentation maintenance • Simplest to use

Mail merge is a software operation describing the production of multiple documents from a single document form and a structured data source. The letter may be sent out to many "recipients" with small changes, such as a change of address or a change in the greeting line. Microsoft Word Mail Merge allows a user to send letters or documents to many people simultaneously; users simply create one document that contains the information that will be the same in each version, and then add placeholders for the information that will be unique to each version. Mail Merge process depends on which user use. This slide created with Microsoft Office 2007.

In familiar applications such as digital versatile disc (DVD), digital video can be found in digital TV, Internet video streaming, digital high-definition television is defined formula. Digital video sharing digital format all functions, including lossless transmission, lossless storage, easy to edit.Currently in many applications, including video conferencing, video games entertainment, DVD discs, digital video broadcasting. As digital video compression format storage requirements prohibitive, lossy digital video compression technology commonly used as the data transmission rate and a compromise between quality. In this paper, we compare and analyze the MPEG-2 , H.261 and H.264 video compression standards.After the Compression , We get the result that the compression of H.264 is better than other two but it take much time as compare to H.261 on higher cost.

This presentation origins from a webinar presented by Luís Faria. The webinar presents the SCAPE developed tools Scout and C3PO and demonstrates how to identify preservation risks in your content and, at the same time, share your content profile information with others to open new opportunities. Scout, the preservation watch system, centralizes all the necessary knowledge on the same platform, cross-referencing this knowledge to uncover all preservation risks. Scout automatically fetches information from several sources to populate its knowledge base. For example, Scout integrates with C3PO to get large-scale characterization profiles of content. Furthermore, Scout aims to be a knowledge exchange platform, to allow the community to bring together all the necessary information into the system. The sharing of information opens new opportunities for joining forces against common problems. The webinar was held 26 June 2014.

Hadoop has been used at the State and University Library, Denmark, in connection with an experiment on the migration of a large collection of audio files from mp3 to wav. This experiment was presented by Bolette Ammitzbøll Jurik at ‘SCAPE Information Day at the State and University Library, Denmark’, on 25 June 2014. The information day introduced the EU-funded project SCAPE (Scalable Preservation Environments) and its tools and services to the participants. The experiment used Hadoop and Taverna but also xcorrSound waveform-compare which is a small tool developed within SCAPE to compare the content of audio files.

The State and University Library, Denmark, hosted an information and demonstration day on 25 June 2014 for delegates from other large cultural heritage institutions in Denmark. The information day introduced the EU-funded project SCAPE (Scalable Preservation Environments) and its tools and services to the participants. Read more about the event in this blog post, http://bit.ly/SCAPE_SB_Demo. One of the presentations was given by Asger Askov Blekinge who showed how the library has worked on integrating its digital object management system with Hadoop. The library is currently digitizing 32 million newspaper pages and is using Hadoop map/reduce jobs to do quality assurance on the digitized files with the help of the SCAPE Stager/Loader so updated QA’ed files are stored in the repository.

This presentation describes the EU-funded project SCAPE – Scalable Preservation Environments –, its developments and sustainability plans. The SCAPE project has developed scalable services for planning and execution of institutional preservation strategies on an open source platform that orchestrates semi-automated workflows for large-scale, heterogeneous collections of complex digital objects. The project run-time was around 3½ years from 2011 to 2014. Read more about SCAPE at www.scape-project.eu

This presentation was given as part of a SCAPE Training event on ‘Effective Evidence-Based Preservation Planning’ in Aarhus, Denmark, 13-14 November 2013. Artur Kulmukhametov, Vienna University of Technology, introduced the importance of content profiling and how this can be done with the help of the SCAPE developed tool C3PO. Content profiling is based on characteristics extracted from the files’ metadata and will help the user to plan digital preservation. The tool C3PO can be easily integrated with both PLATO and Scout.
