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.

What is a DVD?
Hi Alice. Luckily, I found a DVD containing
his information
?

No !!! That thing is unreadable
!Error: DVDunreadable
Don’t be silly, Alice. It was popular in 100 years ago.
It can be read by DVD reader.See it !!

Hey, … How to open PDF file?
!
Fortunately, I can get that file.Can you open “obama2009.pdf”
Error: No program can open file format PDF

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
13
• An active management of digital information to ensure its – Maintainability
Bitstream is still be existing originally– Accessibility
Bitstream forming a file is able to be opened– Renderability
An opened file presents a digital object originally– Understandability
A reader understand a digital object originally
over the time

Objective

The objective is that a reader (consumer) is able to perceive information context following his/her background knowledge and understand it originally.
16
Underlying Community Knowledge
08/04August
4• 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.
17
From simple Math function f(x) = y
Underlying Community Knowledge
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
08/04April
8producer.interpret( “08/04” ) “4th of August”
consumer.interpret( “08/04” ) “8th of April”
Why consumer understand incorrectly?
19
• 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”

Is it possible?

producer.interpret( “08/04” ) “4th of August”
consumer.interpret( “04/08” ) “4th of Auguse”

Right now, Consumer get incorrect understanding from language that Producer need to present.

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

Consumer understand D’ as same thing as Producer understand D.
It means that D’ has preservability relation with D.

Challenges
26
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
27
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
28
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
29
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
30
Terminology and Wish List for a Formal Theory of Preservation
• Need of knowledge preservation
31
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.
32
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
33
• 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
• 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
