SDMX-NA and BOP: new DSD packages published

The Ownership Group for SDMX implementation in Balance of Payments (BOP), Foreign Direct Investment (FDI) and National Accounts (NA) is pleased to inform you that updated DSDs have been made available for NA and BOP. FDI was not updated at this time.

The new National Accounts release adds support for SNA93, Euro Area 19 extension, additional coding for ESA-GFS tables and other minor additions after comments received from data providers and international organisations. Along with the new DSDs, updated Excel templates have been published, which support the new DSD versions. Apart from some ESA-GFS tables, all templates are fully backwards compatible with earlier versions of the DSDs.

For more details, release notes and downloads please consult the SDMX-NA maintenance page or SDMX-BOP/FDI maintenance page.

Public Review Announcement for the new VTL language, allowing the definition and exchange of validation and transformation rules

A dedicated task-force of the SDMX Technical Working Group (TWG) submits the new specification of a Validation and Transformation Language (VTL) for public review. The review period extends until 8th November 2014 in order to allow time for consolidation of a final version at the end of 2014.  Feedback is welcome.

At the end of 2012, the SDMX Secretariat requested the TWG to start a new work package on “Expressions and Calculations” aimed at allowing the definition and the exchange of validation and transformation rules, based on the generic framework for defining mathematical expressions already existing in the SDMX information model. To make such framework fully operational, a standard language for defining validation and transformation rules (set of operators, their syntax and semantics) should be adopted, while appropriate IT formats for exchanging such rules – and web services to store and retrieve them – should be designed.

The intention is to provide a language which is usable by statisticians to express logical validation rules and transformations on data, whether described as a dimensional table or as unit-record data. Although a work-product of SDMX, the VTL language is based on the GSIM data model and should be usable with other standards as well. The present draft for public review also provides (in its part 1) a formal description of data validation at business level against which information models can be mapped.

VTL – part 1: Validation and Transformation Language (General Description)

VTL – part 2: Validation and Transformation Language (Library of Operators)

SDMX for National Accounts: NA_SEC DSD fast track change

The Ownership Group for SDMX implementation in Balance of Payments (BOP), Foreign Direct Investment (FDI) and National Accounts (NA) published a fast track change of the data structure definition for Sector Account and Government Finance (NA_SEC) with the new version V1.3 (on 08/08/2014). The current version was missing a code (“NC”) in the code list CL_CONSOLIDATION. This code list is only used in the NA_SEC DSD, thus the other DSDs in the package remain on V1.2. You only need to update to the new DSD, if your data flow requires the code “NC” for CL_CONSOLIDATION. This is not the case for ESA 2010. Thus no change is needed for reporting ESA 2010 tables to Eurostat. The NA_SEC templates are nevertheless re-published with version V1.3a (on 11/08/2014) in order to be aligned with the versioning of the DSD and in order to correct some minor mistakes found by data providers when testing V1.2c of the tables. All templates are fully compatible with V1.2 of the NA_SEC DSD. You will also find some further details in the issue log on the SDMX-NA maintenance page:
