DDI Training Group welcomes two new co-chairs: Jane Fry and Anja Perry

The DDI Training Group welcomes two new co-chairs: Jane Fry (Carleton University) and Anja Perry (GESIS Data Archive for the Social Sciences). They replace Amber Leahey (Scholars Portal), who served as chair for four years. The DDI Alliance is very grateful for the time and effort Amber put into training activities.

The mission of the Training group is to:

  • Introduce people to DDI and improve people's competence in working with DDI
  • Gear training to specific audiences
  • Develop expertise within the community for training purposes
  • Maintain a training library with updated training material for reuse

To fulfill this mission, the group is taking the following steps in the next year:

  1. Complete sets of training material based on the output of a Train-the-Trainer Workshop at Dagstuhl in 2018 and add them to the Training Library for reuse.
  2. Recruit new members for the group and additional instructors to be able to teach DDI to a wider audience.
  3. Identify conferences and further outlets where DDI teaching can take place and set up a yearly teaching schedule.
  4. Use GO FAIR to further promote DDI through training events.

The Training group is looking for more members! Interested in joining? Please contact Jane ( or Anja (

DDI XKOS released for public use

The DDI Alliance ( is pleased to announce the public release of XKOS version 1.2, a free and open specification that facilitates sharing and management of statistical classifications.

XKOS is a simple and elegant model to represent complex classifications via their structural and textual properties, as well as the relations between classifications. By leveraging the widely-used Simple Knowledge Organization System (SKOS), XKOS extensions allow linkages to a wealth of existing thesauri and taxonomies to better support statistical classifications and concept management systems. XKOS also refines SKOS semantic properties to allow the use of more specific relations between statistical concepts, classifications, or any other case where SKOS is employed.

XKOS is currently used at a number of national statistical agencies and has been available as a draft since 2013. Since undergoing a final review in 2017, all issues have been addressed and corrected in preparation for the publication of version 1.2.

Links to the specification and instructions for comment are found at:

Anil Arora, Chief Statistician of Canada, spoke during the opening keynote speech, "Enabling the modernization of official statistics with metadata standards." Mr. Arora noted, "A national statistical office must deliver timely insights that are grounded in quality, backed by good methodology. And in order to do that, we are intricately dependent on international standards, like the DDI." He later added, "Standards like DDI are going to be crucial if we are to keep pace with the knowledge cycle that constantly surfaces more and more data. This standard will enable timeliness but will also ensure high quality insights."
