DDI Discovery: An Overview of Current RDF Vocabularies

DDI Discovery: An Overview of Current RDF Vocabularies Arofan Gregory Metadata Technologies NA Joachim Wackerow GESIS Background For many years, interest has been increasing in the set of

standards-based technologies from W3C around Linked Data (aka The Semantic Web, RDF, etc.) RDF stands for the Resource Description Framework a way of making the Web semantically richer and machine-actionable In the recent past, these technologies have shown increasing promise DDI has always been an XML standard But this has changed! DDI now does both RDF and XML as underlying syntaxes for

implementation RDF is based on the model implicit in DDI Codebook and DDI Lifecycle XML A Tale of Two Ontologies This presentation is not a modelers view of the DDI RDF ontologies Thomas Bosch of GESIS (and others) have done many good presentations in this style

This is more of a general overview, to explain what has been developed and published, and how it might broaden the use of DDI DDI RDF Discovery Vocabulary (studies & research data) XKOS Vocabulary (statistical classifications) Well, Maybe Three Ontologies

In the recent past, as a result of pressure from the Open Data movement in the UK, an ontology had been developed for publishing aggregate statistics Data Cube Now part of the W3C Open Data suite of standards This was based on the Statistical Data and Metadata Exchange (SDMX) standard Also designed to be used as a description of tabulations

in a DDI-based vocabulary for describing microdata DDI RDF Discovery Vocabulary (Disco) The initial application of DDI to RDF was to handle the majority use-case we see with RDF Publication on the Web! Describes conceptual metadata about studies and data sets for finding them across the Web of Linked Data Both at the study level and at the variable level

For research data, this is a function most often seen after data has been produced and disseminated Data archives Data libraries Data producers Statistical and government agencies XKOS

The second most-used RDF vocabulary is the Simple Knowledge Organization System (SKOS) vocabulary XKOS is a set of extensions to SKOS to support formal statistical classifications Useful as a stand-alone vocabulary, and in combination with Disco and Data Cube DDI Discovery

The Full Picture DDI Discovery Publication Available on the DDI Alliance website ( www.ddialliance.org) As an HTML specification, but also available in machine-processable formats (TURTLE, N3, RDF XML)

Unofficial Draft status Still responding to implementers issues and comments Relatively stable XKOS XKOS Publication Available at the DDI Alliance website

Published as an HTML specification Also published in machine-actionable formats (TURTLE, N3, RDF XML) Also with an Unofficial Draft status More stable than the Disco vocabulary Looking Forward There is one more RDF vocabulary being worked on in this series

Achim Wackerow will present this in the next session The next generation DDI 4 will provide broader support for RDF Every part of the DDI Model will be expressed both as a set of XML schemas and as a set of RDF vocabularies DDI 4 as a Model-Based Standard

DDI 4 Model Semantically Equivalent DDI XML Schemas DDI RDF Vocabularioes
