rsdmx - Tools for reading SDMX data and metadata in R
3 likes3,534 views
The document discusses the rsdmx package in R, which provides tools for reading Statistical Data and Metadata Exchange (SDMX) data and metadata documents. It describes the motivation for developing rsdmx to facilitate reading SDMX documents in R. It outlines the object-oriented architecture of rsdmx, how it represents different SDMX message types as classes, and its main functions like readSDMX() for importing SDMX files. The document concludes by demonstrating how to use rsdmx to import SDMX datasets, concepts, codelists, and data structure definitions into R.

rsdmx
Architecture - Object-oriented model
SDMX model represented in RR with S4 classes and methods
In S4 modelling, a class is made of slots (properties)
the general structure of SDMX-ML document is represented
with an SDMX abstract class
each SDMX-ML document has a corresponding RR SDMX*
class that extends the SDMX class
SDMX RR representation
Class "SDMX" [package "rsdmx"]
Slots:
Name: xmlObj schema header
Class: XMLInternalDocument SDMXSchema SDMXHeader
Known Subclasses:
"SDMXGenericData", "SDMXCompactData", "SDMXMessageGroup",
"SDMXConcepts", "SDMXCodelists", "SDMXDataStructures",
"SDMXDataStructureDefinition"

rsdmx
Usage - readSDMX with the helping approach
rsdmx now brings the capacity to query data from a set of
well-known data providers, still using the single readSDMX function.
rsdmx embedds a list of SDMX service providers by default.
The list of data providers ”known”by readSDMX can be queried as
follows:
R> providers <- getSDMXServiceProviders()
R> sapply(providers, slot, "agencyId")
[1] "ECB" "ESTAT" "OECD" "FAO" "ILO"
The following example shows how to use readSDMX based on one
of known data provider, OECD:
R> sdmx <- readSDMX(agencyId = "OECD", operation = "GetData", key = "MIG",
filter = list("TOT", NULL, NULL),
start = 2011, end = 2011)
