SDMX/DDI Dialogue Session 5

 

 

Wednesday 5 October 2011, meeting / telephone conference

Chair:  Steven Vale

Attendees: See list in annex

 

Item 1: Update on progress on mapping vocabularies

 

Marco Pellegrino gave an update on work to develop a SDMX technical vocabulary, which aims to define the terms used in the information model. The first draft has now been circulated within the SDMX community for feedback. The next step is to identify relevant DDI terms, and create a combined vocabulary.

 

 

Item 2: Update on the development of business cases for collaboration between DDI and SDMX

 

Alistair Hamilton introduced a draft of the core of the proposed business case document, focusing on harnessing DDI and SDMX to support end-to-end statistical business processes, where the inputs are microdata. Participants gave general feedback on this document, including the importance of appropriate governance. They agreed that it contains all the main elements, but needs to be streamlined.

 

There was concern that both SDMX and DDI are evolving, making integration more challenging. August Götzfried will request a written statement from the SDMX sponsors in support of the dialogue, to complement that already received from the DDI Alliance. DDI profiles should be identified to support the use cases. Alistair will liaise with Eurostat on the definition of these profiles.

 

 

Item 3: Feedback from the Eurostat DDI / SDMX Workshop

 

Marco Pellegrino gave a report of the workshop hosted by Eurostat on 9 September, in the context of the ESSNet project on SDMX. The main issue for this workshop was the use of SDMX in the early phases of the GSBPM. The main outcomes were that SDMX and DDI were seen as complementary, the two main work areas identified by the SDMX/DDI Dialogue (terminology and business case) were seen as important and should be pursued, and there is a need to link to potential user groups, such as the new OECD group on microdata access.

 


Item 4: Relations with other international groups and initiatives

 

The SDMX Action Plan 2011-2015 has been released, and is available via www.sdmx.org . This plan contains an item on the interoperability of SDMX and DDI.

 

The SDMX Statistical Working Group held its first face-to-face meeting over the previous two days. A work programme has been agreed, and an important topic of discussion was whether the content-oriented guidelines should be de-coupled from the SDMX technical standards, and elevated to a higher level, independent of any technical implementation.

 

 

Item 5: How to organise the dialogue in future

 

The mailing list for the Dialogue has grown to well over 50 people. It was agreed that this number is not really practical for teleconferences. Steven Vale will contact those on the mailing list to see whether they are happy just to receive notification of events and copies of materials by e-mail, or whether they want to be part of a core group that are more actively involved in developing the outputs.

 

It was also proposed to set up three task teams covering work on vocabularies, the business case, and SDMX / DDI in the context of micro-data access. Those on the mailing list will be given the opportunity to commit to participating actively in these tasks.

 

Item 6: Next meeting

 

The timing of the next meeting will be determined when it is known who intends to participate in the core group.
