SDMX/DDI Dialogue Core Group

 

 

Tuesday 11 December 2012, telephone conference

Present: Franck Cotton, Dan Gillman, Al Hamilton, Thérèse Lalor, Achim Wackerow, Adam Wronski and Steve Vale.

Observers: John Csaki and Justin Lynch

Apologies: Arofan Gregory and Juan Munoz

 

1.               Progress reports from Task Teams

 

a)      Task Team 1: Vocabularies

 

There has been little progress due to most of the people concerned being heavily involved in the Generic Statistical Information Model (GSIM) Development Project during 2012. However, the recent DDI workshops in Dagstuhl have shown that there is still a strong interest in mapping and harmonising vocabularies between standards. 

 

b)      Task Team 2: Business Case

 

Al reported that a possible new business case is emerging from the work on “standards-based modernisation”, led by the High-Level Group for the Modernisation of Statistical Production and Services (HLG). The development of the GSIM should strengthen the case for using SDMX and DDI in different parts of the statistical process. The SDMX Technical Working Group is looking at possible scenarios.

 

c)      Task Team 3: Access to Microdata

 

Thérèse reported that there has been some work to review relevant microdata initiatives and consider possible communication materials. Arofan has been working on expressing register data in SDMX and DDI with Banca d’Italia.

 

 

2.               The impact of GSIM

 

The group discussed how the emergence of GSIM would affect the Dialogue. It was agreed that GSIM is a different sort of standard, so it would not be right to talk about a “trilogue”. However, GSIM should facilitate the mapping of standards, and help to identify gaps and overlaps, as well as relationships between objects in SDMX and DDI.

 

Arofan and Chris Nelson will be working on mappings between GSIM and DDI, and GSIM and SDMX  early in 2013. The group agreed that it would be useful to set up a Task Team to review this work. Steve will contact the Dialogue mailing list to ask for expressions of interest for this Task Team.

 

 

3.               Governance of standardisation issues

 

Steve reported that the governance structure for work on the standards needed for modernisation, under the Conference of European Statisticians, is currently under review. One possible outcome would be the creation of a Standards Steering Group, which ideally would contain representatives of standards organisations from outside official statistics, such as the DDI Alliance. The HLG is also establishing a project to support the implementation and integration of standards relevant for statistical modernisation. The Core Group will need to consider whether / how the Dialogue will fit into this new governance structure.
