Enhanced Publications:
an introduction
Arjan Hogenaar
11 June 2012
DANS is an institute of KNAW and NWO

2. DANS
Data Archiving and Networked Services
• Sustainable access to digital research data
• Promoting trusted digital repositories (DSA)
But also
• Services like EASY, NARCIS and National Resolver

3. Enhanced Publications
(Traditional) publications enhanced with:
- Datasets
- Video fragments
- Audio fragments
- Images
- Detailed Information on Organisation/Author
- In order to clarify the context
- Not all these components have to be included in
an EP
3

4. Two fundamental ways to compose EPs
A. ‘Machine-based composition’
• The objects brought together shared already one
or more properties
• Examples:
– ARVODI (in the Netherlands): project description, publication
and dataset share a unique identifier
- OpenAIREPlus: the EU Grant agreement number
• Relationships between the objects are ‘unbiased’
4

5. Two fundamental ways to compose EPs
B. ‘Man-made composition’
• The objects brought together based on the opinion
of the composer
• Not always clear why a typical object (an image)
has been related to – for instance – a publication
5

6. Is there a relationships
between these two teams?
Denmark
Netherlands

7. OAI-ORE (Object Re-use and
Exchange) for EPs (some basics)
• Resource Map to describe an EP (in OAI-ORE: an
aggegration)
• Aggregation to describe the components of an EP
(in OAI-ORE: the aggregated resources)
• Aggregated resources may be documents
(Eprints) , datasets (data objects), images,
metadata records, authors (persons) and so on
7

8. Data Model of EPs
Van de Sompel: OAI-ORE Primer
8

9. Advantages EPs
• Background information easy to find
• Conclusions in a paper may be verified via the
dataset(s) used
• Information is being presented in context
9

10. Additional Advantages of manmade EPs
• Authors may not simply relate components, but add
comment why they have chosen to relate them
• An author may allow other researchers to add
components to the original EP: an EP is no longer a
static document
• But be aware: in the case of man-made EPs it is not
always clear why objects have been put together into
one single EP!

11. Example of an EP:
textual representation
Not very revolutionary! But…. See the xml!

12. Rdf/xml serialisation of the OAIORE of an EP:
<rdf:RDF>
<rdf:Description rdf:about="http://escape.utwente.nl/rem/561">
<rdf:type rdf:resource="http://www.openarchives.org/ore/terms/ResourceMap"/>
<dcterms:created>2011-02-16T14:43:57.756Z</dcterms:created>
<dcterms:modified>2011-05-05T08:09:09.571Z</dcterms:modified>
<ore:describes rdf:resource="http://escape.utwente.nl/aggregation/561"/>
<dcterms:creator rdf:nodeID="183fb582"/>
</rdf:Description>
<rdf:Description rdf:nodeID="183fb582">
<foaf:name>ESCAPE repository</foaf:name>
<foaf:page rdf:resource="http://escape.utwente.nl/"/>
</rdf:Description>
<rdf:Description rdf:about="http://escape.utwente.nl/aggregation/561">
etc

13. EPs and DANS
DANS has three major services:
– The portal NARCIS
– The Archiving System for Datasets: EASY
– The National Resolver
13

14. EASY and Resolver
• EASY is used both as a system to deposit
datasets and as an access point to search for
datasets: https://easy.dans.knaw.nl/ui/home
• The Resolver is a new service, resolving the
persistent identifier of an object to its actual URL.
The Resolver is crucial in the realisation of
sustainable access to information objects:
http://persistent-identifier.nl/
14

15. NARCIS
• Main national portal to research information,
publications and datasets (from EASY and
3TU.Datacentrum)
• Information gathered using OAI-PMH protocol
• Is a starting point for the developments of EPs,
as most of the EP-components (project
descriptions, descriptions of researchers and
institutions, metadata of publications and
datasets) have been incorporated in the portal:
www.narcis.nl
15

16. EPs in NARCIS
• In co-operation with SURF in 2011:
– Study into the possibilities to present EPs in NARCIS
– under the following conditions:
• OAI-PMH to harvest descriptions of EPs
• OAI-ORE to describe the relationships between objects
within EPs or between different EPs
• RDF/xml for the serialisation of EPs
• Incorporation of a visualisation tool to present EPs
• Use of persistent identifiers for authors and objects
16

17. Visualisation of an EP in NARCIS: from RDF/xml to user-friendlyness
Only use this slide to present a screenshot of an application.
As no style is applied, the screenshot can take up the whole
slide. For all other information please use the slide with
preset style!

18. Digital Author Identifier:
its role in EPs
* No doubt on the identity of an author
* Centralised system in the Netherlands
* May be used in publications, datasets,
project descriptions and of course in EPs
R.L. Zijdeman has the DAI:
304832960
18

19. Persistent Identifiers:
separating a resource form its actual URL
• URLs of object is not stable
• But: assigning a PID to an object may overcome
this problem
• The combination of the object, its PID and an
resolver service (to translate the PID in the actual
URL of the object) facilitates sustainable access
A thesis and its PID as part of an
EP in NARCIS
19

20. EP: summary
1. Total new way in information dissemination
2. EP’s may be deposited in repository just like
traditional publications
3. OAI-PMH may be used for the harvesting of
description of metadata of EP’s
4. Description of EPs relies on OAI-ORE model
(with resource maps and aggregations)
20

21. Two key aspects in EP
development
• Digital Preservation
• Data Curation
21

22. Digital Preservation
Components of an EP have to be sustainable available
– For publications:
electronic depots of national libraries
assigning Persistent Identifiers to the objects
secure information infrastructure
- For datasets: Data Curation
- Data management plan
- Data Seal of Approval (DSA)
22

23. Digital Curation of Datasets
A. Data Management Plan (at the start of a project) :
Describing nature of data
Describing way of data collection
Hard- and software to be used
Describing intellectual property rights and legal
requirements
• Describing (re-)use of data
•
•
•
•
23

24. Digital curation of Data
B. Data Seal Of Approval (DSA)
http://datasealofapproval.org/
• Ensuring sustainable access to research data
• Guidelines for:
– Data producer
– Data archive
– Data consumer
• Self-assessment, peer reviewed by DSA board,
whereafter DSA wil be granted
• Trust is crucial
24

25. Open Access (as seen from a funder)
NWO (Netherlands Organisation for Scientific Research)
promotes Open Access in two ways:
1. Open Access to research publications
2. Open Access to research data
25

26. NWO OA policy: publications
• Publications as results of research projects supported
by NWO should, irrespective of other publication
possibilities, be made accessible to the general public
as quickly as possible via Open Access.
• Copyrights may only be assigned to a third party
insofar as this does not block the option to publish
via Open Access
• Deviation from this rule is only possible with the
explicit prior approval of NWO.
26

27. NWO OA policy: research data
Aim:
Maximise access to data for re-use (‘Open
Access unless specified otherwise’)
Means: Setting up an Open Access Code of Conduct
to make rights and obligations visible to all
stakeholders
Legally: NWO is considered to be the co-producer of
data generated as a result of a NWO-grant
Practice:Data collected during a research project have
to be stored and documented in a thorough
and accessible manner
27

28. Other challenges
1. Authors may combine components from different
sources
2. Therefore, sustainable access not guaranteed for all
components
3. Maintenance of dynamic composed publications is
technically no problem, but the versioning is.
4. Copyright rules may vary for the different components
