DDI DIRECTIONS: Logo of the DDI Alliance’s Newsletter

Im aktuellen Newsletter DDI DIRECTIONS der DDI Alliance, der insbesondere über die Mailingliste [DDI-users] versandt wird, ist erstmals die Kolumne Read-Write-Execute (RWX) erschienen, die auf wissenschaftliche Publikationen aus dem Bereich Metadaten hinweisen will. Die Kolumne könnte auch ein Beispiel sein für entsprechende Informationen aus der (deutschsprachigen) Forschungsdatenszene, Interessierte können sich gerne bei Knut Wenzig melden. Hier die Ankündigung und der Text aus dem Newsletter:

The DDI Community has produced a rich store of DDI and metadata-related publications over the last 20 years. Read-Write-Execute (RWX) will highlight some of these existing publications as well as new work as it is produced. This first column will feature some of the foundations of DDI in scientific literature. (Thanks to Achim Wackerow for his suggestions and to Kelly Chatain for editorial assistance.) At the same time, a bibliography of DDI articles, working papers, and presentations is being built and is available at Bibsonomy.org with easily reusable bibliographic metadata. This metadata will also be made available on the DDI Alliance website. Suggestions for papers and topics for RWX, or the bibliography, are appreciated and can be sent to: Knut Wenzig, kwenzig@diw.de.

In her paper “The DDI matures: 1997 to the Present”, Mary Vardigan (2013), the former Director of the DDI Alliance, presents a timeline of the conceptual and organizational development of DDI. The initial SGML Codebook Committee meeting occurred in 1995, but 1997 was the year of the first “instantiation in XML” (Vardigan 2013: 45). DDI started (in versions 1 and 2) to describe data sets by the codebook approach, which is still supported and widely in use. From version 3 on the scope was broadened to document the whole lifecycle of data, using data collection as a starting point, and finally enabling repurposing and reuse of DDI elements.[1] The paper ends with a list of high level design goals, referred to in “Developing a Model-Driven DDI Specification” (Participants in 2012 Dagstuhl Seminar on DDI Moving Forward, 2012), on which the next version of DDI is based.

The first reference listed in Mary Vardigan’s paper is “Providing Global Access to Distributed Data Through Metadata Standardisation – the Parallel Stories of NESSTAR and the DDI”, submitted by the Norwegian Social Science Data Services and prepared by Jostein Ryssevik (1999). The “relative distance between the end-users of a statistical material and the production process” (p. 2) was identified as the fundamental problem to be solved. As discovery systems were provided to address this problem, the need for metadata standards like DDI emerged. The authors recall that DDI used the new (at the time) XML language, and that the defined XML code could contain the description of the document itself, of the study, the file, the variables, and other study-related materials. Already in this early paper RDF (Resource Description Framework[2]) is described as an application “that provides the foundation for metadata interoperability across different resource description communities.” (p. 5) Using DDI as a language, the medium NESSTAR could deliver a great range of interconnected services and platforms. Even if the last release of NESSTAR is more than one year old, the ideas in the article – whether or not realized by the software – deserve to be revisited. Using the metaphoric antonym of Bazaars vs. Cathedrals, the same authors (Ryssevik 2000) conceptualize their vision of – even then! – metadata systems that cover the complete life-cycle.

The article “The Data Documentation Initiative”, by Grant Blank and Karsten Boye Rasmussen (2004), was published in Social Science Computer Review, one of the top ranked academic journals in the “Information Science & Library Science” category. The authors describe the requirements of data documentation in the social sciences, how DDI as an XML based standard can be used to store information presented in codebooks, and how “standardization creates new opportunities for software development to aid users.” (p. 314)

Today, after 20 years, we can read and reevaluate those ideas only because people took the time to write them down. In this sense contributing to the scientific inventories of knowledge should be understood as a best practice and an integral part of software development for the academic community.

[1] Version 3 is described in Vardigan, Heus, Thomas 2008.
[2] Vardigan (2013: 48) expects that RDF will be used in the upcoming version of DDI as a connection to the semantic web.
