Tools for Reading SDMX Data and Metadata

Description

RSDMX is a package to parse/read SDMX documents in R. It provides: - a set of classes and methods to read data and metadata documents exchanged through theStatistical Data and Metadata Exchange (SDMX) framework. The package currently focuses on the SDMX XML standard format (SDMX-ML). - an web-service interface to well-known SDMX data providers

Class "SDMX"

Description

An abstract class from which SDMX classes are derived

Usage

SDMX(xmlObj, namespaces)

Arguments

xmlObj

object of class "XMLInternalDocument derived from XML package

namespaces

object of class "data.frame" given the list of namespace URIs

Value

an object of class "SDMX"

Slots

xmlObj: Object of class "XMLInternalDocument" derived from XML package
schema: Object of class "SDMXSchema", handles the version of SDMX-ML format
header: Object of class "SDMXHeader", handles the SDMX-ML document header
footer: Object of class "SDMXFooter", handles the SDMX-ML document footer

Warning

This class is not useful in itself, but all SDMX classes in this package derive from it.

Note

Currently, the approach drafted in rsdmx package was to rely on XML package, read the xml object and store it as part of the SDMX R object. Another approach being investigated is to use XML handlers throughthe Simple API for XML (SAX) that could avoid to load the full XML tree in the SDMX R object (xmlObj). Indeed, SDMX data could be huge and causes issues of memory if the complete XML tree is loaded in the R user session.

Details

The handler function will list the resource methods. Each method will accept a single object of class SDMXRequestParams as argument. This object will give the different request params as slots (baseUrl, agencyId, resource, resourceId, version, flowRef, key, start, end, compliant) to build the output (a string representing the web request to build).

The rsdmx package will as much as possible try to handler generic handlers. At now, the available embedded builders are: SDMXREST20RequestBuilder (connector for SDMX 2.0 web-services), SDMXREST21RequestBuilder (connector for SDMX 2.1 web-services), SDMXDotStatRequestBuilder (connector for SDMX .Stat web-services implementations)

formatter: an object of class "list" giving a formatting function (for each resource) that takes an object of class "SDMXRequestParams" as single argument. Such parameter allows to customize eventual params (e.g. specific data provider rules)
handler: an object of class "list" that will be in charge of build a web request.
compliant: an object of class "logical" indicating if the request builder is somehow compliant with a service specification
unsupportedResources: an object of class "character" giving one or more resources not supported by the Request builder for a given provider

readSDMX

Description

readSDMX is the main function to use to read SDMX data

Usage

readSDMX(file = NULL, isURL = TRUE, isRData = FALSE,
  provider = NULL, providerId = NULL, providerKey = NULL,
  agencyId = NULL, resource = NULL, resourceId = NULL, version = NULL,
  flowRef = NULL, key = NULL, key.mode = "R", start = NULL, end = NULL, dsd = FALSE,
  headers = list(), validate = FALSE, references = NULL,
  verbose = !is.null(logger), logger = "INFO", ...)

Arguments

file

path to SDMX-ML document that needs to be parsed

isURL

a value of class "logical" either the path is an url, and data has to be downloaded from a SDMXweb-repository. Default value is TRUE. Ignored in case readSDMX is used with helpers (based on the embedded list of SDMXServiceProvider)

isRData

a value of class "logical" either the path is local RData file handling an object of class "SDMX", previously saved with saveSDMX. Default value is FALSE.

provider

an object of class "SDMXServiceProvider". If specified, file and isURL arguments will be ignored.

providerId

an object of class "character" representing a provider id. It has to be match a default provider as listed ingetSDMXServiceProviders()

providerKey

an object of class "character" giving a key to authenticate for the given provider endpoint. Some providers may require an authentication or subscription key to perform SDMX requests.

agencyId

an object of class "character representing an agency id, for which data should be requested (from a particular service provider)

resource

an object of class "character" giving the SDMX service request resource to query e.g. "data". Recognized if a valid provider or provide id has been specified as argument.

resourceId

an object of class "character" giving a SDMX service resource Id, e.g. the id of a data structure

version

an object of class "character" giving a SDMX resource version, e.g. the version of a dataflow.

flowRef

an object of class "character" giving the SDMX flow ref id. Recognized if valid provider or provide id has been specified as argument.

key

an object of class "character" or "list" giving the SDMX data key/filter to apply. Recognized if a valid provider or provide id has been specified as argument. If key.mode is equal to "R" (default value), filter has to be an object of class "list" representing the filters to apply to the dataset, otherwise the filter will be a string.

key.mode

an object of class "character" indicating if the key has to be provided as an R object, ie a object of class "list" representing the filter(s) to apply. Default value is "R". Alternative value is "SDMX"

start

an object of class "integer" or "character" giving the SDMX start time to apply. Recognized if a valid provider or provide id has been specified as argument.

end

an object of class "integer" or "character" giving the SDMX end time to apply. Recognized if a valid provider or provide id has been specified as argument.

dsd

an Object of class "logical" if an attempt to inherit the DSD should be performed. Active only if "readSDMX" is used as helper method (ie if data is fetched using an embedded service provider. Default is FALSE

headers

an object of class "list" that contains any additional headers for the request.

validate

an object of class "logical" indicating if a validation check has to be performed on the SDMX-ML document to check its SDMX compliance when reading it. Default is FALSE.

references

an object of class "character" giving the instructions to return (or not) the artefacts referenced by the artefact to be returned.

verbose

an Object of class "logical" that indicates if rsdmx logs should appear to user. Default is set to FALSE (see argument logger).

logger

reports if a logger has to be used to print log messages. Default is NULL (no logs). Use "INFO" to print rsdmx logs, and "DEBUG" to print verbose messages from SDMX web requests.

...

(any other parameter to pass to httr::GET request)

Value

an object of class "SDMX"

setSDMXServiceProviders

Description

function used internally by rsdmx, when loading the package, to set the list of SDMXServiceProvider known by rsdmx (hence known by readSDMX to query data/metadata in an easier way). For internal use only (this function does not provide any value for the end user, but it is here documented for transparency, and to explain how the package works.)

Usage

setSDMXServiceProviders()
