1. SDMX data discovery, query, and visualisation within Excel

Metadata Technology

2. Why Integrate with Excel?
Excel is a familiar desktop tool
Used to import data (usually as CSV)
View data as tables and charts
Manipulate data
It is not typically used to query data sources
Therefore the choreography of accessing data in Excel has multiple steps
This choreography does not lend itself to data discovery and query

3. Typical Choreography for Data Query and Viewing in Excel
Data Web Service
query
User Interface
response
Download as CSV
save
view
load

4. Solution Develop an add-in for Excel that can:
Interface to a web service that
Delivers information on data sources (what is available)
Delivers information that can be used to query data sources – wherever they are
Queries the data sources
Delivers data and corresponding structural metadata that enables intelligent display of data
Possibility to provide data manipulation useful for statisticians and analysts (extrapolation, seasonal adjustment)

5. Simple Web Services for Data Discovery & Visualisation

Simple Web Services for Data Discovery & Visualisation
Fusion Cube
Fusion Cube uses structural information to build a rich & powerful model. (DSD/Codelists/Concepts/HCL/Constraints/Structure Maps/MSD)
It exposes the information via a set of simple web services tailored to aid data discover and data visualisation
We are in the proccess of building an Excel client to use this information to assist in both data discovery and data visualisation
We would like to work with NcomVA to help us incorporate visual widgets that can be used by clients to assemble a data dissemination system
