What is Rosetta?

Rosetta is a complete digital asset management and preservation

solution that addresses the ever-growing need to collect, archive

and preserve the digitally-born and digitized materials stored at

academic institutions, research organizations, and government

institutions, ensuring data integrity and access over time.

Need for Digital Preservation

Today’s world is digital. If a file can’t be opened, probably

the reasons are:

1. Corrupted media

2. Missing rendering application

3. Un-identified file format

7

Need for Digital Preservation

All Kinds of institutions must preserve & provide

long term access to information

The Challenges

9

Challenges

Active preservation principles:

1) Ensuring bit integrity

2) Ensuring content health • Format viability• Complete metadata• Provenance

3) OAIS compliant system

10

Challenge 1: Bit Integrity

• Fixity checks determine if data has changed or corrupted

• Basic feature found in asset management as well as

preservation solutions

• Does not guaranty data access – just that it has not changed

11

Challenge 2: Content Health

• Formats evolve rapidly and become obsolete

• File access requirements:

• Positive ID of format e.g. pdf

• SW application e.g. Acrobat reader

• Complete Metadata:

• Technical metadata (e.g. size, resolution, compression,

etc)

• Descriptive metadata (e.g. author, title, publisher, etc)

• Provenance Metadata

Rosetta Solutions – Submission Applications

• Deposit work flows out of the box

• Automated (ftp, NFS, etc)

• Manual

• SDK (software development kit) with API’s allows building submission

tools to interact with Rosetta deposit module

Data Model

26

PREMIS

• Preservation metadata: implementation strategies

• International working group concerned with developing

metadata for use in digital preservation

• Metadata for intellectual entities, events, agents and rights

• Data model consisted of several entities:• Intellectual entity

• Representation

• File

• Bit-stream

27

METS

• Ex Libris has a METS profile that will be published and

open.

• Each Intellectual Entity is one METS

• Each representation is a file group

• Structure map is on the representation level

• Metadata stored for all levels descriptive as DMD and

preservation as AMD.

28

Data Model

Intellectual Entitya coherent set of content that is reasonably described as a unit, for example, a particular book, map, photograph, or database

Representation

1

N

is the set of files, including structural metadata, needed for a complete and reasonable rendition of an Intellectual Entity

File

1

N

is a named and ordered sequence of bytes that is known by an operating system

Bit-Stream

1

NA bit-stream is data within a file that has meaningful common properties for preservation purposes.
