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-ref
CO Metadata Object file Title Author(s) Simple (compound) object model
Semantics: types of objects in CO • info:eu-repo/semantics/descriptiveMetadata [1, 2, ...] • info:eu-repo/semantics/objectFile [0, 1, 2, ...] • info:eu-repo/semantics/humanStartPage [0, 1] NEEO proposal: If Item == objectFile • info:eu-repo/semantics/publishedVersion • info:eu-repo/semantics/authorVersion More types to be added: • Data set • Chapter • etc
CO Metadata Object file Titel Auteur(s) Enhancing publication with data set Metadata Object file DDI • What belongs to what? Extra semantics • Same data can be used by other publications. Separate CO for data set • Note that for some researchers the data set and the publication belong together; without the publication the data set misses its context.
CO CO Metadata Metadata Object file Object file DDI Titel Auteur(s) CO can be component of another CO Aggregation ore:aggregates / ore:isAggregatedBy Aggregation
Driver-II D4.2 Report on Object Models and Functionalities SURF foundation, 6 November 2008Peter Verhaar
Aims of the report • 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
Definition • 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. publication Compound data object ePrint data metadata
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
Driver II: M4.1 Datasets & Demonstrator for Enhanced Publications The Demonstrator is available at: • http://driver2.dans.knaw.nl/demonstrator/html/ • Login: driver2 / bijrijder • Best: Firefox 3.0 and Java VM Techniques: • OAI-ORE v0.9 • RDF • XSLT • XHTML • CSS and Javascript
Introduction: objectives and partners • 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).
Collection van publications Publication (enhanced) MODS Object file Dataset Reference list Enhanced object file Dataset DDI Instance Publication Data file SPSS file Software Three types of aggregation (CO’s)
The ingredients of the demonstrator • Repository EURotterdam • Data files • DDI • Repository UvTilburg • Repository SamenInDelen • DIDL representations of COs • New objects, not in other repo’s • XSL stylesheets • Application (Cocoon: transformations) • Identifier -> DIDL & DDI -> HTML/Atom • DIDL -> MODS/DC
