Agenda • 22nd Century • Knowledge Preservation • Challenges • islandora
22nd Century Hi Bob, do you have information about USA president “Barack Obama” Oh! It is hard to find out. Because the information is older than 100 years.
22nd Century Hi Alice. Luckily, I found a DVD containing his information ? What is a DVD?
22nd Century Don’t be silly, Alice. It was popular in 100 years ago. It can be read by DVD reader. See it !! ! Error: DVD unreadable No !!! That thing is unreadable
22nd Century Fortunately, I can get that file. Can you open “obama2009.pdf” ! Error: No program can open file format PDF Hey, … How to open PDF file?
22nd Century As I see, it need Adobe Reader 9.0 to open it. File is read protected Please key password How I know the password?
22nd Century Why the author documented in alien language? ? ! !7rò??àÕ ??ߟ²ÂÚ Õ??ߟ²ÂÚ ðŽɳ !Z?g! Õr/ÕŸ/?rò?
22nd Century Confuse!!! When he was born? 4th August or 8th April ? . . . Barack Obama 44th president of USA Born08/04 /1961
22nd Century What should I do if I need to find more information relevance to Barack Obama’s family? You may have to browse every file from here. Good luck …
22nd Century It would be good if an older generation has a good plan for digital preservation
Digital Preservation • An active management ofdigitalinformation to ensure its • MaintainabilityBitstream is still be existing originally • AccessibilityBitstream forming a file is able to be opened • RenderabilityAn opened file presents a digital object originally • UnderstandabilityA reader understand a digital object originally over the time wikipedia.org
Knowledge Preservation • Terminology and Wish List • for a Formal Theory • of Preservation • Giorgos Flouris • FORTH or ICS • CNR of ISTIfgeo@ics.forth.gr • flouris@isti.cnr.it • Meghan BanachCNR of ISTI • meghini@isti.cnr.it
Objective Ingest Archive System Render Producer The objective is that a reader (consumer) is able to perceive information context following his/her background knowledge and understand it originally. Barack Obama 44th president of USA Born04-Aug-1961 Consumer
Underlying Community Knowledge August 4 08/04 • The producer need to represent “4th of August” in a common language. Thus, she need to use contextual, knowledge, or commonsense information that she agree with her community in order to write a symbol representing “4th of August”. • She decides to use “08/04” because everyone in the same community understand this and can interpret to “4th of August”. • It means that she, and readers in the same community at that period understand the same meaning.
Underlying Community Knowledge From simple Math function f(x) = y Every people use Interpret function to understand meaning of language producer.interpret( “08/04” ) “4th of August” reader01.interpret( “08/04” ) “4th of August” reader02.interpret( “08/04” ) “4th of August” In this case, everyone interprets language “08/04” to be “4th of August” because inside the interpret process has formula. Formula comes from knowledge. If knowledge is agreed in community, formula is produced from community knowledge. It means that Producer and all reader have the same formula, so they understand the same thing together.
Evaluation of DC April 8 08/04 producer.interpret( “08/04” ) “4th of August” consumer.interpret( “08/04” ) “8th of April” Why consumer understand incorrectly?
Evaluation of DC • When the time change, designated community may be changed, and knowledge may be changed. • Thus, “understanding” may be changed, too. • The critical cause is a change of UCK. • Because difference UCK makes difference formula that makes difference understanding. • Next challenge is “How to capture change of UCK”
Evaluation of DC Is it possible? producer.interpret( “08/04” ) “4th of August” consumer.interpret( “04/08” ) “4th of Auguse”
Evaluation of DC UCK UCK Formula Formula Read Read 08/04 Producer Consumer Digital Object D Right now, Consumer get incorrect understanding from language that Producer need to present.
Evaluation of DC UCK UCK UCKES Formula Formula UCKMS 08/04 Producer Consumer Digital Object D The system should understand knowledge from Consumer’s side and generate mapping between Producer’s formula and Consumer’s formula using UCKES and UCKMS mechanism
Evaluation of DC UCK UCK UCKES Formula Formula UCKMS Read Read 08/04 04/08 Producer Consumer Digital Object D’ Digital Object D Then, the system transform the digital object D to be D’. D’ contains language that make Consumer understand same thing as Producer
Summary D’ D Barack Obama Barack Obama 44th president of USA 44th president of USA Born08/04 /1961 Born04/08 /1961 Consumer understand D’ as same thing as Producer understand D. It means that D’ has preservability relation with D. D’ D
Discovering the Information Needs of Humanists When Planning an Institutional Repository - 2011 • Need of teaching material preservation • Need of document process (versioning) • Need of connection with external datasource • Need of including usage statistic
Preserving Digital Documents: Choices, Approaches, and Standards - 2004 • attach metadata to objects when you want to preserve them, rather than hard specifics that would be more typical in interchange format, because Preservation metadata today is seldom shared across organizations
The Institutional Repository Rediscovered: What Can a University Do for Open Access Publishing - 2007 • Repository as a Platform for Peer-Reviewed Journals • Make repository as open access publisher • The repository should produce, showcase, and share an institution's exciting and original research • Provide to create a research community to expand the boundaries of knowledge
Institutional Repositories and Digital Preservation: Assessing Current Practices at Research Libraries - 2011 • To realize to implement Digital Archive in Institutional Repository • To Make Agreements and secure permissions for preserving IR contents • To have guidance of digital format preservation to content contributors
Terminology and Wish List for a Formal Theory of Preservation • Need of knowledge preservation
The Paradox of Digital Preservation • In organizations, workflow processes continuously create documents and records. Starting from creation and ingestion, we should integrate the workflow process with the preservation process: appraisal, verification, maintenance, and, eventually, retirement.
Evaluation of Semantic and Social Technologies for Digital Libraries - 2008 • The users are more eager to depend results of their search process on the automated solutions, such as recommendations, and on their trust in the information provided by their friends. Therefore, the meaning of semantics in the digital libraries should heavily include the social semantics. Future research on semantic features should concentrate more on improving accuracy of automated recommendations services and usability of existing solutions
Sketchy idea • Approach METADATA model that supports • Variety types of digital object • Many mime/type (including teaching material) • Digitized and born-digital object • Data preservation • Preservation activities, Right and agreement, Requirement to access and render a digital object, • Document process and versioning • Create, review, … • Relationship between digital object • Linked data • Semantic search • RDF, SPARQL • Sharing metadata • Knowledge preservation • Ontology, Linked data
islandora Overview • Institution • University of Prince Edward Island's Robertson Library • Description • Islandora is an open source project underway at the Robertson Library at the University of Prince Edward Island. Islandora combines the Drupal and Fedora software applications to create a robust digital asset management system that can be used for any requirement where collaboration and digital data stewardship, for the short and long term, are critical. • Tools • Fedora Repository + GSearch, Drupal, and Solr • Link • http://islandora.ca example from fedora-commons.org
