Enhanced Publication
• A digital publication enhanced or enriched by extra digital content, e.g., by the corresponding data set
• The digital publication and the extra content form a compound digital object
• The components of a compound digital object are digital objects that can be distributed over the web– compound of distributed digital objects– not a package of digital objects by-value, but by-

Report on Object Models and Functionalities
SURF foundation, 6 November 2008Peter Verhaar
□ Identification of requirements for the storage and management of enhanced publications
□ Data model
□ Recommendations for serialisation of the data model in RDF/XML using the OAI-ORE model
Aims of the report
□ Enhanced publications are compound digital objects which combine ePrints with one or more metadata records, one or more data resources, or any combination of these.
Definition

ePrint data metadataCompound data object
All entities have
• identifier
• semanticType
All entities are digital objects (atomic, CO)
Versioning, provenance
ORE in short
• ORE: Object Reuse and Exchange
• Exchange of compound objects on the web
• Composing new objects on the basis of web resources
• Linked to Semantic Web and especially to Linked Data (RDF Lite over HTTP)
In the words of Herbert Van de Sompel
• Subject: Aggregations of Web resources
• Approach: Publish Resource Maps to the Web that Instantiate, Describe, and Identify Aggregations
• Object Reuse and Exchange: Towards a Machine-Readable Web
Enhanced Publication as an ORE Aggregation

1. Objectives SURF-project “Samen in Delen’’ (”Together in Sharing”)
Create 6 enhanced publications, for 3 types of research data:
survey data (wp1).
experimental economics (wp 2).
financial data (wp3).
Evaluate DDI 3.0 in the context of EP ‘s (wp4).
Create a sustainable environment for EP’s (wp5).
Commitment, procedures, infrastructure.
Set up a demonstrator for EP’s (wp6).
