  Release

A new version of the DPF Manager has been released!.

There are several improvements in this update. The most significant one is the redesign of the reports section, where now it is easier (and much faster) to browse the analyzed reports, transforming between formats, and also converting a quick check to a full check. The global report has also been improved with a more visual and interactive panel

Other interesting new functionalities and enhancements are the following:

  • The METS report is generated in all the cases (previously it was only genereated if there where no errors at all.
  • Download reports from the GUI functionality
  • Added pagination functionality to improve the efficiency (specially when thousands of files are checked)
  • Included execution time duration to global reports
  • Fixed bugs related to the zipped tiff files validation.
  • Delete report from global reports page
  • Sorting reports by the passed column now shows first the ones that have warnings
  • Bugfix when trying to send feedback with non-xml reports.
  • Compatibility with old reports (previous to version 3.3)

See the full list of new functionalities in the github tag page and the list of solved issues.

What is DPFManager?

DPF Manager is the most advanced TIFF conformance checker for digital preservation that has been created and designed by a strong community of experts who are highly interested in file format validation for digital preservation. This project have created a strong community around it and become an essential tool for memory institutions, software developers and integrators and those interested in the long term preservation of digital still-image assets.

This initiative has been boosted by PREFORMA, a PCP project that aims to address the challenge of implementing good quality standardized file formats for preserving data content in the long term.

DPFManager is the new tool for archivists

DPF Manager allows archivists to know the state of their TIFF images in terms of preservation. It validates the files with the main standards (Baseline 6, TIFF-EP, TIFF-IT), and additionally checks the conformance to the newest TIFF for Archival (TI/A) Recommendations (in process of ISO standardization). Although your TIFF files are conformant to the main standards this does not guarantee long-term preservation. DPF Manager ensures you compliance to these set of recommendations, that is, your image digital assets will be prepared for digital preservation. DPF Manager also allows to create custom policies in order to define specific archive criteria for accepting files, such as file size, image format, representation, compression, metadata info, etc. The tool also offers the possibility to fix some common file bugs through the metadata fixer. Everything is reported to the user with both human readable (experts and non-experts) and machine readable report formats.

Discover the new functionalities (over version 3.0):

User Interfaces

  • Statistics section
  • Quick checks option
  • Improved overall performance
  • PDF report viewer
  • Browse reports folder

Reports

  • Included hints to solve errors
  • More complete PDF reports
  • Clarified policies texts
  • More comprehensive metadata analysis section
  • Show namespace in XMP
  • Display file size
  • Store execution time
  • Copiable text in reports

Policy checker and metadata fixer

  • Long edge policy check
  • Solve ascii encoding fix

Other features

  • Full 32 and 64 bits compatibility
  • Create configuration files through CLI

  DPF Manager

A lot of improvements and new features have been included in the new release of the DPF Manager.

The most important changes are the inclusion of a Quick Check functionality that allows to perform a fast validation of the files, which can be later analyzed in more detail if desired performing a full check. Also, the reports now include hints that explain how to fix them (whenever possible). A new metadata fix has been added to solve ascii encodings (a common baseline error, that is produced by many softwares and operating systems). And now, the PDF reports can be seen directly from the GUI (instead of opening an external PDF viewer).

This release also includes some minor improvements and a set of bugfixes, that can be seen in the github page and the list of issues closed in the current milestone.

The benchmarking tool anounced in the past release is in progress and will be ready in the release of July.

We present a new update of the DPF Manager. This new version can be downloaded as usual from the download section

This new version includes several improvements and fixes. One of the most interesting new features is the Statistics Module. This new section reports the most usual tags found in the analyzed files, as well as their values. Also from the ISOs validated, it is shown the errors that have been found ordered by frequency.

The rest of the enhancements and bugfixes of this new release are listed below.

  • Improved reports section efficiency.
  • Filter unreadable tags in reports.
  • Fixed some errors related with the metadata fixer.
  • Added default configuration to periodical checks definition.

In the next release, we plan to create a benchmarking tool where the DPF Manager will be compared with other well-known TIFF validators such as Jhove and Jhove2

Don't forget to give us feedback to continue improving the project!

  Release

During May 2017, successful hands-on sessions and workshops have been organised by PREFORMA in several places to explain to the participants what does conformance checking mean, why is file format validation so important in long-term digital preservation, how to create their own policy profiles and how to download, install, configure and use the conformance checker to analyse their files. These workshops invite participants to bring their files and analyse them with the PREFORMA tools...

Barcelona, 10 May 2017

The first hands on session was organised in Barcelona with members of the Official Association of Librarians (Col·legi Oficial de Bibliotecaris i Documentalistes de Catalunya – COBDC), to show the functionalities offered by the DPF Manager to check TIFF files.

It took place in the premises of COBDC on the 10th of May and the session was conducted by Sònia Oliveras from the Girona City Council and Xavier Tarrés and Víctor Muñoz from Easy Innova. The attendees, who have large amounts of TIFF files, came mostly from local and national memory institutions and weren’t aware of any file conformance checker. The tools offered by PREFORMA project were the first solution in order to solve the file format conformance.

This update solves some bugs and includes some enhancements. This is the list of changes.

  • Rewriten table in reports section. Now it is much faster and there are no more display errors.
  • Bugfix related to the internal database when few memory is available for the virtual machine
  • Show all running tasks from GUI (not only the tasks that started after the start, but also the ones that started before and are still running)
  • Possibility to run the CLI with the java jar (which allows the user to specify custom virtual machine parameters)
  • Option -t of the command line interface is now working properly
  • New --silence and --show-report options for CLI, in order not to display info messages and open the report at the end

We would like to thank you for all the received feedback in the Github issue tracker. Your help is much appreciated!

In this release we have also been working hard on the testing and validation of the platform, and will continue doing so in the next months. A new repository has been created for this purpose, and all the possible TIFF errors have been defined and classified. This repository has been named ground truth and will be used as a tool to validate and assure the correctness of DPF Manager.

IMAGE AND RESEARCH CONFERENCE

The Centre for Image Research and Diffusion (CRDI) of the Girona City Council and the Association of Archivists of Catalonia, are calling the 14th Image and Research International Conference, which will be held in the Palau de Congressos de Girona from 17th to 18th of November. Previously, on 16th, four workshops related to the areas of interest of the Conference will be organized.


OUR WORKSHOP
PREFORMA: A tool to guarantee the preservation of digital cultural heritage

Memory institutions face increasing volumes of electronic documents and other media content for long term preservation. Data are normally stored in specific formats for documents, images, sound, video, etc., produced by software from different vendors. This software is controlled neither by the institution producing the files, nor by the institution that archives it. This obligates memory institutions to carry out conformance tests before accepting transfers of electronic collections, but again these are beyond the control of the institution and can be unreliable. Digital content, meant for preservation, passing through an uncontrolled generative process can jeopardise the preservation process.
The workshop will present the results of PREFORMA, a PCP project which aims to give memory institutions full control of the conformance testing of filescreated, migrated and ingested into archives, including a demonstration of the conformance checker DPF Manager developed during the prototyping phase. This will inform a discussion with the digital preservation community – open source community, developers, standardization bodies and memory institutions – about the opportunities offered by PREFORMA and the challenges that are still to be addressed.

Digital Preservation: the three webinars

In this blogpost we want to share the last webinars available online. We hope you enjoy the three topics that all teams are working on.

  • What to learn today?

  • PREFORMA WEBINAR: DPF MANAGER
    Some Long Term Preservation activities may conflict with goal of raid production and dissemination of digital information. DPF Manager aims to reduce the time and effort required to revise file structure, metadata and the institution acceptance criteria as well as giving advice about image preservability. For more information about DPF Manager project visit: http://www.dpfmanager.org/.



    Hosted by Open Preservation Foundation.

  • PREFORMA WEBINAR: MEDIACONCH
    MediaConch is an extensible, open source software project consisting of an implementation checker, policy checker, reporter, and fixer that targets preservation-level audiovisual files (specifically Matroska, Linear Pulse Code Modulation (LPCM) and FF Video Codec 1 (FFV1)) for use in memory institutions, providing detailed and batch-level conformance checking via an adaptable and flexible application program interface accessible by the command line, a graphical user interface, or a web-based shell. The webinar will discuss the background and context of the creation of the software, provide demonstrations of the software’s graphical user interface and command line functionality, and inform participants of the future directions of the project.
    Available soon!

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

This software is controlled neither by the institution producing the files, nor by the institution that archives it.

This poses problems for long-term preservation. Digital content, meant for preservation, passing through an uncontrolled generative process can jeopardise the preservation process. The objective of PREFORMA (PREservation FORMAts for culture information/e-archives) – a Pre Commercial Procurement project co-funded by the European Commission under its FP7-ICT Programme – is to give memory institutions full control of the conformance testing of files created, migrated and ingested into archives. This is achieved through the development of open source tools which enable this process within an iteration that is under the full control of memory institutions. The project aims to establish a sustainable ecosystem involving interested stakeholders from a variety of backgrounds, including researchers, developers and memory institutions. The workshop will present the results of the project, including demonstration of the conformance checkers developed during the prototyping phase. This will inform a discussion with the digital preservation community – open source community, developers, standardization bodies and memory institutions – about the opportunities offered by PREFORMA and the challenges that are still to be addressed.

A new version of the DPF Manager has been released. Version 2.5 includes a set of new features, improvements and fixes and is now available to download in the download section.

One of the new features is the generation of the METS format for the XML report. The METS schema is a standard for encoding descriptive, administrative, and structural metadata regarding objects within a digital library expressed with XML. This standard is maintained in the Network Development and MARC Standards Office of the Library of Congress, and is being developed as an initiative of the Digital Library Federation. METS standard can be used in the role of an Archival Information Package (AIP), Submission Information Package (SIP) or Dissemination Information Package (SIP) within the Open Archival Information System (OAIS) reference model, which ensures the DPF Manager integrability with Memory Institutions applying the OAIS model in their data object lifecycle. We also include in the METS report a NISO section and future releases will also include a PREMIS section.

Also, the HTML report now shows more comprehensively the XMP history (if present) of the TIFF file. We have also made improvements in the GUI appearance, to homogenize the fonts and text sizes.

Another great improvement has been made with the TIFF Writer that now saves files much faster than before.

We have also made several improvements on the implementation checker and the policy checker, adding more rules, checks and warnings. The full set of changes of this new release can be found in the github release page.

  • Periodical checks. This new feature allows the user to program checks to be run periodically (either daily, weekly or monthly) performing a check using a specific configuration.
  • The style of the report has been improved and now includes some icons to identify the fields more easily.
  • The report has been also improved adding new sections for showing more complete information of the fields ICC Profile, XMP, IPTC and EXIF.
  • The implementation checker has been updated with more warning rules to inform the user of possible problems in the TIFF file.
  • Bugfixes and stability improvements.

The next monthly release will be available by the end of this month. You can check the list of work to be done during this month in the Github Milestones section.

A new update of the DPF Manager is available to download. Version 2.3 comes with an online validator that can be accessed through the web. The online validator allows any user to check for Tiff files and see a complete report of its contents.

The desktop version of DPF manager includes now the possibility to change the language of the interface, both in GUI and CLI modes. For now, only English and Spanish languages have been added.

If you want to translate the application to another language just create a new language file and put it in the resources directory of the repository, or contact us to get more information.

Other new features and improvements of this release are:

  • Icc Profile inspection.
  • New policy rules (uneven DPI, XYResolution, extra channels).
  • TreeView for selecting files and folders from the GUI.
  • Overall performance has been highly increased. Now conformance checks run at least 5 times faster.
  • Warnings in the implementation checker report.
  • Configuration file in XML format.

  Release

DPF Manager version 2.2 has been released. This new version includes the possibility to stop, pause and resume tasks, new policy checker rules, client-server execution mode, and some other bug fixes and stability improvements.

The most important new feature of this release is the implementation of the client-server architecture. DPF Manager can now be executed in server mode in one computer and client-mode in another computer, so that the client can send a request to the server to make a job and get the result back when it’s done. This mode is useful for companies or institutions having dedicated machines for intensive computing processes, or when the TIFF files are stored in servers with thousands or millions of files to check, so it could be better to start the checking process remotely.

This new mode will be also helpful for the next new features that we are going to develop in upcoming releases, like the web mode, which will likely be ready for the next monthly release.

A full log of changes for this new release is available in Github. The DPF Manager installer for Windows, Linux and Mac OSX can be downloaded from the download section. Don’t hesitate to contact us for any question/suggestion.

  Release

After the redesign phase, a new version of the DPF Manager is available. The version 2.0 includes many new functionalities and improvements and is now ready to download in the website. The main changes of this version are the following.

  • The graphical interface has been redesigned, using a better lightweight framework.
  • The console window has been integrated within a widget in the GUI itself.
  • Now it is much easier for developers to edit and create new implementation checkers, because they are now written with XML files, instead of hardcoded in the source.
  • A logging system has been created for easier error reporting.
  • The DPF Manager now provides an API for external developers to be able to communicate with it, performing checks and receiving the reports.

More detailed information on all the changes in this new version can be found in github.

A demo of the application will be shown in the Open Source Preservation Workshop, held in Stockholm, 7 April 2016.

Please download DPF Manager and test the 2.0 release. Your feedback is essential to keep improving the software.

DPF Manager is an application and a framework designed to allow end users and developers to gain full control over the technical properties and structure of TIFF images intended for Long Term Preservation.

In considering the suitability of particular Data object for the purposes of preserving digital information as an authentic resource for future generations, relies on the use of a stable, open and well documented file format as well as some data object properties acceptance criteria.

The main objective is to give memory institutions full control of the process of the conformity checks of files. This is a four-step process:

  • Identification: determining the file format of a Data Object based on the file extension and the file signature.
  • Validation: validating the conformance to a specific normative. These normative can be defined by some standardization organization or specific acceptance criteria based on a locally-defined policy rules
  • Modification: modifying the Data Object, preserving the Information Representation, in order to make it more suitable for long term preservation.
  • Reporting: collecting and submitting the data object structure and metadata as well as validation result with the modification information.

The project is open-source in order to achieve the overall objectives of the PREFORMA PREFORMA challenge. This open-source approach ensures that memory institutions will always have access to the required tools for deploying a long-term sustainable preservation workflow, supported and maintained by the associated ecosystems.

PREFORMA’s Project Management Team (PMT) visited Easy Innova last week

PREFORMA’s Project Management Team (PMT) visited Easy Innova last week Between 20 and 30 January 2016, a team of representatives of the PREFORMA project, coordinated by Peter Pharow of Fraunhofer IDMT, visited the three consortia that are currently working in the prototyping phase: veraPDF, Easy Innova and MediaArea.net.

Aim of the visits is to better know each other, get in a closer touch with the suppliers, see the people working in their own environment, analyse the current status of the three open source projects and start future possible collaborations. Peter Pharow, Börje Justrell, Antonella Fresa, Benjamin Yousefi and Sònia Oliveras i Artau composed the PREFORMA delegation who participated in the first visit, which was planned at Easy Innova premises in Girona on 20-21 January 2016. The team discussed with members of Easy Innova and of the University of Basel several topics, among which: status of DPF Manager; evolving functionalities including interoperability and API; usability and user requirements, user groups, scenarios; testing for quality assurance and accuracy; transparency of code, media files, and more; achieving reference implementation; awareness of what is still missing; process of community building; status of standardization activities. In addition, a representative from the National Technical University of Athens (Marios Phiniketos) joined the meeting to plan the integration of DPF Manager into the Technical Space, a web based application for the development of applications and services based on digital cultural content developed in the framework of the Europeana Space project.

The other two visits (to veraPDF and MediaArea.net) are planned on 27 and 28 January in Brussels, in the occasion of the FOSDEM Conference . More details will follow soon!

DPF Manager is part of PREFORMA Project, which takes an approach that implies that all software developed is released established open source development practices with early and frequent releases of developed software.

After working on the first version, we have improved it launching the new version that is ready to be downloaded.

The DPF Manager TIFF conformance checker was able to detect the tags inside the TIFF (baseline tags, extension tags and widely used private tags) and handle with embedded metadata as ICC Profiles, XMP, IPTC and EXIF.

The implementation checker validates:

  • TIFF baseline 6.0
  • TIFF/EP (Tag Image File Format/Electronic Photography) ISO:12234-2
  • TIFF/IT (Graphic technology – Prepress digital data exchange – Tag image file format for image technology) ISO 12639:2004E

With policy checker memory institutions can create custom rules to define their own acceptance criteria

  • Byte order
  • Image with
  • Imager Height
  • Image pixel density

In this release, the metadata fixer is able to manage metadata inside the TIFF adding or deleting tags. Furthermore, the metadata fixer can apply auto-fixes created by developers.

The reporter module now provides a human readable report (PDF and HTML format) and a machine readable report (XML and JSON format) for each file checked. Moreover, the report includes a comparison between the original image file and the new file generated by the metadata fixer module.

This release includes a Command Line Interface (CLI) and a Graphical User Interface (GUI) with a wizard to create and save configurations, check files and directories selecting a saved configuration and view the reports generated by the tool.

Your contribution is very important to guarantee the best possible outcome.

Download it and provide us with your feedback.
