1 Co-funded by the European Union under FP7-ICT Alliance Permanent Access to the Records of Science in Europe Network Co-ordinated by aparsen.eu #APARSEN The VCoE: what it offers David Giaretta, APA APARSEN webinar, November 2014

2 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Solutions to problems related to digital preservation Based on experience and expertise of the “pioneers” of digital preservation All kinds of digital objects –But  Audio visual – perhaps better done by PrestoCentre  Documents and images – perhaps better done by OPF Need to: –Define the solution : CONSULTANCY –Using : TOOLS & SERVICES –Your people then need : TRAINING

3 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN CHALLENGES Different types of digital objects e.g. –Rendered – simple images, sound, video, documents –Data – needs meaning of numbers etc –Software –Time dependent Many different tools and services – many lists Many sources – APARSEN members and others Many terminologies, many glossaries NEED AN INTEGRATED VIEW

4 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Many models – why another? See -cycle-models-for-digital-stewardship / -cycle-models-for-digital-stewardship

5 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN …and more Data Lifecycle Models and Concepts by CEOS, 2012, see 20Lifecycle%20Models%20and%20Conc epts%20v13.docx

6 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Integrated vision If the payback is not immediate then the resources need to be justified Since the resources have to be found somehow, the question “who pays and why?” if often heard To justify the resources needed for preservation one needs to identify the potential value. To maintain, for even increase, the likely value, the techniques chosen for preservation plays a key role. nity/common-vision/http://www.alliancepermanentaccess.org/index.php/commu nity/common-vision/ Clickable image to showing related research

8 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Training Consistency through the “Integrated View”

9 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Click on PRESERVATION:

10 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Basic preservation activities Libraries say: “Emulate or migrate” –Works well with data only in special cases  Can repeat what was done before instead of new things –Does not help with building cross-disciplinary communities Can repeat what has been done before BUT Cannot use new applications Convert to format which new software can use BUT What if there are many software systems?

11 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Preservation techniques For each technique look for evidence – what evidence? must at least make sure we consider different types of data –rendered vs non-rendered –composite vs simple –dynamic vs static –active vs passive must look at all types of threats

12 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Evidence APA/APARSEN list of tools: s-for-preservation/ s-for-preservation/ –details of preservation related software, examples of data and the evidence of preservation linking software to types of data. Some of this evidence comes from specific testbeds but much comes from user scenarios.details of preservation related softwareexamples of dataevidence of preservation linking software to types of datatestbedsuser scenarios

13 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Tools evidence based selection linked to SCIDIP-ES toolkits

15 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Other evidence and tools CASPAR project large amount collected evidence about the effectiveness of tools and services for many different types of data: –Scientific –Cultural heritage –Contemporary performing arts Prototyped the tools and services These have been developed in SCIDIP-ES and platform.digitalpreserve.info platform.digitalpreserve.info Also massive collection of information about views of thousands of researchers, data managers and publishers across disciplines and around the world – PARSE.Insight

16 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN When things change We need to: –Know something has changed –Identify the implications of that change –Decide on the best course of action for preservation –What RepInfo we need to fill the gaps  Created by someone else or creating a new one –If transformed: how to maintain data authenticity –Alternatively: hand it over to another repository –Make sure data continues to be usable Orchestration Service Gap Identification Service Preservation Strategy Tk RepInfo Registry Service Authenticity Toolkit Storage Service Data Virtualisa tion Toolkit Process Virtualisa tion Toolkit RepInf o Toolkit

17 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN ThreatRequirement for solution Users may be unable to understand or use the data e.g. the semantics, format, processes or algorithms involved Ability to create and maintain adequate Representation Information Non-maintainability of essential hardware, software or support environment may make the information inaccessible Ability to share information about the availability of hardware and software and their replacements/substitutes The chain of evidence may be lost and there may be lack of certainty of provenance or authenticity Ability to bring together evidence from diverse sources about the Authenticity of a digital object Access and use restrictions may make it difficult to reuse data, or alternatively may not be respected in future Ability to deal with Digital Rights correctly in a changing and evolving environment Loss of ability to identify the location of data An ID resolver which is really persistent The current custodian of the data, whether an organisation or project, may cease to exist at some point in the future Brokering of organisations to hold data and the ability to package together the information needed to transfer information between organisations ready for long term preservation The ones we trust to look after the digital holdings may let us down Certification process so that one can have confidence about whom to trust to preserve data holdings over the long term RepInfo toolkit, Packager and Registry – to create and store Representation Information. In addition the Orchestration Manager and Knowledge Gap Manager help to ensure that the RepInfo is adequate. Registry and Orchestration Manager to exchange information about the obsolescence of hardware and software, amongst other changes. The Representation Information will include such things as software source code and emulators. Authenticity toolkit will allow one to capture evidence from many sources which may be used to judge Authenticity. Packaging toolkit to package access rights policy into AIP Persistent Identifier system: such a system will allow objects to be located over time. Orchestration Manager will, amongst other things, allow the exchange of information about datasets which need to be passed from one curator to another. Certification toolkit to help repository manager capture evidence for ISO Audit and Certification

19 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Terminologies – APARSEN DP Glossary Why another? Provides relationships between different terms from the various glossaries OAIS, APARSEN, DPC, ANZ, SNIA, INTERPARES, TDR (ISO 16363) –Uses SKOS to organise the terms – tells us whether a term is  Broader / narrower / related to another term  See pglossary/ pglossary/  Each term has a URI e.g. Representation Information: pglossary/#Representation_Information pglossary/#Representation_Information

20 The VCoE: what it offers David Giaretta, APA Webinar, November 2014 Co-funded by the European Union under FP7-ICT aparsen.eu #APARSEN Representation_Information In scheme:OAIS Definition: The information that maps a Data Object into more meaningful concepts. An example of Representation Information for a bit sequence which is a FITS file might consist of the FITS standard which defines the format plus a dictionary which defines the meaning in the file of keywords which are not part of the standard. Another example is JPEG software which is used to render a JPEG file; rendering the JPEG file as bits is not very meaningful to humans but the software, which embodies an understanding of the JPEG standard, maps the bits into pixels which can then be rendered as an image for human viewing.
