rsdmx - Tools for reading SDMX data and metadata in R

• First initiative to read SDMX in R made available to the R community

• Generic SDMX abstraction library in R language, with a large bandwidth of use:

– Support for SDMX 1.0, 2.0 and 2.1 standard formats

– Read SDMX documents from remoteor local sources, with no restriction to SDMX standard web-services

• Capacity to read:– Data

Variety of formats (generic, compact, etc.)

– Metadata

Data structure definition (DSD), includingCodelists, Concepts, etc.

rsdmx in action• readSDMX() a unique function, whatever it is data or metadata!

sdmx <- readSDMX(dataURL)

• as.data.frame() converts the data into the easy-to-use tabular R data.frame object

data <- as.data.frame(sdmx)

• Perspectives– Enhancing the core reading functions

• Support for more SDMX document types• Support for new reading methods (e.g. Simple API for XML)

– Towards a writeSDMX() function, for sharing derivate data in SDMX format– Build user- friendly interfaces to query SDMX services
