Dagstuhl Sprint, October 2017 (Week One)


Purpose

Introduction

The DDI (Data Documentation Initiative) metadata standard, originally created in 1995 to document social science research data, has in recent years become relevant to new user groups, including the official statistics and medical research communities. In order to respond to these new users, DDI is developing a model-based specification (DDI Version 4) that can be expressed in XML Schema, RDF-S/OWL, relational database schema, and program languages. Such a data model will make it easier to interact with other disciplines and other standards, to understand the specification, to develop and maintain it in a consistent and structured way, and to enable software development that is less dependent on specific DDI versions.

Goals

The overall goal of both DDI workshops in Dagstuhl 2017 is to combine the good and mature parts of the work of the last years in order to have three working functional views, a working class library, the resulting bindings and a working production framework. This will be an important step for the publication of a pilot of DDI 4 which is planned for publication in the middle of 2018. The pilot should prove that the new approaches of DDI 4 work and make sense. This includes especially the model-driven approach, the functional views, and the datum-based data description.

The three planned functional views are Data Description, Data Capture, and Codebook. The goal is to have working functional views with core sets of items (in contrast of functional views which cover everything in the specific area). Additional features can be added to the views in future.

Existing work should be used, refined, and integrated. Start of new work should be minimized and only focus on missing parts which could block the finalization of working components.

Issues in this work – especially missing parts – should be described with underlying reasoning and plan for resolution (including priority level)

All working areas can be understood as a building block for the goal described above. Additionally, work will be done on strategic documents including the plan for a DDI-based infrastructure, the future strategic plan, and mission and guiding principles.

Topics Overview

The workshop will focus on five main areas of work:

Re-usable Structured Documentation

  • Improvement of structure. Definition of required and optional items for multiple documentation types.
  • Modular examples with the perspective of a specific audiences or purposes
    • Software developer, archivist, data producer, training tutorial
    • The examples should be realized in the used technical format (restructured text)
    • Examples in different target formats should be realized, like for single documents, linked documents, slides.
  • This work will continue similar work in the 2016 workshop in Dagstuhl.

Production Framework

Test Cases

  • Technical test cases in binding syntax (XML and RDF) for core items of Functional Views (Data Description and Data Capture). The test cases of W3C specifications are the role model for this. A good example is the suite of test cases for CSV on the Web.

RDF-S/OWL

Work plan and partial resolution of tasks described in document from Cologne meeting (2016-12). Details see document “RDF Work Specification”.

Program Libraries

  • Java binding
    • Conceptual approach: documentation, rules, prototype, review of existing approaches.
    • Rules for round trip of metadata between bindings, especially XML, RDF, and Java
      • Each representation has its own limitations. These limitations shouldn’t have an influence on the metadata round trip. A common set of structural features of these representations could be the solution.
    • JSON-LD. Conceptual approach: generation on basis of RDF-S/OWL or on basis of UML model.
