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.

What is a DVD?

Hi Alice. Luckily, I found a DVD containing

his information

?

22nd Century

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

Confuse!!! When he was born?4th August or 8th April ?

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

Knowledge Preservation

Objective

BarackObama

Producer

Consumer

Render

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”

Evaluation of DC

Is it possible?

Evaluation of DC

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

Summary

BarackObama


Born 04/08 /1961

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

Sketchy idea

islandora

35

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
