The SDMX vision

Users need … • good quality data, up-to-date numbers, documentation

• Single access point for data from different sources

• User interfaces: GUI and also a Web service (for automation)

The SDMX vision …• Data providers (originators) offer their data “in SDMX”

• Dissemination = reporting = data sharing … from a single storage

• SDMX registries help users to find data via a GUI and an SDMX Webservice

The BIS SDMX Sandbox exercise

• How “real” is this SDMX vision?

• How does it work with difference scenarios?

The Sandbox setup “in the cloud”

14 participating central banks: 14 Sandboxes with

• SDMX registry with user interface and SDMX web service

• SDMX data base with data browser and SDMX web service

• Space to host SDMX data files

• User interface for loading files, performing registrations etc.

• Detailed tutorials 1 Sandbox for the BIS to experiment and participate “as central bank” The Data Portal (Unified Data Catalogue or “UDC”)

• “central” SDMX registry operated by the BIS

• Data browser

• Synchronises with the central and CB registries

• Accesses registered data sources SDMX Sandbox was developed by Metadata Technology

SDMX Sandbox setup 14 Sandboxes for central banks, 1 for BIS as central agency, 1 Data portal (Unified Data Catalogue)

Scenarios

1. Data reporting against a “global” SDMX DSD, eg BOP

2. Making internal data available via a “data portal”

3. Bringing external (public) data to your users via a data portal

Common aspects

• data is available in SDMX files in a known DSD or …

• SDMX web service offers data in a known DSD

• We just need to know where the data is and what DSD is follows

• An SDMX Registry is the place for this information

• A simple data browser can offer data selection based on the known DSDs

ECB publishes a lot of data as SDMX files on its website IMF and BIS offer the Joint Ext. Debt Hub (JEDH)

contributions as SDMX files Users may want to see this data via a common data portal Organisations may wish to access this data via a SDMX

2.1 web service (that ECB, IMF and BIS currently do NOT offer) demo

Load SDMX DSD into registry demo

• In future: SDMX registries provide this as a service … Define Dataflow, Provision agreement and Categorisation Register the data files as sources for the UDC demo

Scenario 3: “making public data available in a data portal”

Conclusions I

Building blocks are working in the SDMX Sandbox• SDMX registry and SDMX 2.1 webservice• SDMX data base (with webservice)• Data browser• Unified Data Catalogue (data portal)

Connecting different data sources …• SDMX files from public websites• SDMX files from other (accessible) locations• Different SDMX versions (1.0, 2.0, 2.1)• SDMX databases (internal and external)• SDMX Web service

First implementation of a federated SDMX registry

Conclusions II

Harmonisation of data access techniques was achieved…

• User sees all data through one “data portal” (the UDC)

• SDMX 2.1 web service for all data, also for those offered as SDMX 1.0 files

• Web service supports automated data retrieval

Works best with harmonised data structures!

• BOP example

• Key deliverable for SDMX and domain groups for 2012: DSD for global use for BOP and National Accounts

The SDMX Vision is real!

• SDMX Sandbox is a good tool for promoting SDMX• Tutorials, very intuitive and “hands-on”

• BOP SDMX Portal based on the BIS SDMX Sandbox experience

• Input for SDMX Technical Working Group• Other SDMX sponsors to use it with their constituencies to promote

SDMX?• Any other ideas?

Scenario I: “BOP” (Balance of payments)

National agencies have to “report” their data based on a commonly agreed data structure

This data needs to be available at international organisations and for the public

This is a real life scenario for BOP, National Accounts and other data domains. demo

SDMX BOP data structure “for global use” is a prerequisite

• We invented a simplified one for the purpose of this exercise …

Scenario 2: “dissemination database for BIS”

BIS wishes to disseminate data to internal users via a common data portal (example: BIS Banking Statistics)

BIS has/defines SDMX DSD for this data demo

BIS uses the SDMX database in the Sandbox as “dissemination database” and loads the data via SDMX files demo

Internal users use the data browser (similar to UDC) to access the “BIS SDMX database”. demo

For external dissemination the BIS registers its Sandbox database as a data source to the UDC demo

This also enables the UDC search service for this data demo
