preservation and protection over the
long-term

content
the protection and management of
digital rights is also viewed as taking
place digitally

Approach
• Develop a common understanding of
Digital Rights
and
Digital Rights Management (DRM)
"Digital Rights Management (DRM) involves the description, layering, analysis, valuation, trading and monitoring of
the rights over an enterprise's tangible and intangible assets. DRM covers the digital management of rights - be they
rights in a physical manifestation of a work (eg a book), or be they rights in a digital manifestation of a work (eg an
ebook). “ from: Iannella, R. (2002). Open Digital Rights Language (ODRL) Version 1.1. Retrieved 11 25, 2013, from W3C: http://www.w3.org/TR/odrl/
• Review of existing standards, documents, projects and initiatives
• Analysis results of DRM surveys (like The Dutch DRM survey and the
APARSEN DRM survey) and consider concrete user scenarios
• Provide a common view of the current State-of-the-Art in DRM
techniques and tools (desktop research)
• Classification and Evaluation of DRM techniques against their impact
and risk on the long-term preservation (desktop research)

Digital Rights
• Digital rights refers to the ‘rights’ associated with accessing, using,
creating and publishing digital content. The rights can relate to usage
permissions as well as access preferences or limitations imposed upon
digital content.
• To preserve digital rights information a form of
their digital representation is needed
=> Rights Expression Languages (RELs):
• Examples of RELs:

•
Provenance: Who has had
custody/ownership of the digital object?
Authenticity: Is the digital object what it
purports to be?
Preservation Activity: What has been
done to preserve it?
Technical Environment: What is
needed to render and use it?
Rights Management: Who and what is
allowed to access and use it?
Makes digital objects selfdocumenting across time

PREMIS data model and Rights Statements
•
•
Example:
• Marcel Ras grants KB digital
repository permission to make
three copies of
ncdd_workplan.pdf for
preservation purposes.
An agreement with a rights holder
that grants permission for the
repository to undertake an action(s)
associated with an Object(s) in the
repository.
Not a full rights expression
language; focuses exclusively on
permissions that take the form:
– Agent X grants Permission Y to
the repository in regard to
Object Z.

Challenges
• Preservation of digital rights over the long-term
• Update digital rights information in cases of changing legislative base
RECOMMENDATIONS FOR THE PROTECTION OF DIGITAL
RIGHTS
• DRM could be medium- or high-risky for the long-term preservation,
because: DRM
– restricts access (downloading, streaming)
– controls use (viewing, playing, copying, dissemenation, resell)
• => DRM could hinder preventive and subsequent LTP measures
RECOMMENDATIONS FOR THE HANDLING OF DRM PROTECTED OBJECTS
