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.

  headers = list())

Arguments

regUrl

repoUrl

an object of class "character" giving the base Url of the SDMX service repository

accessKey

an object of class "character" indicating the name of request parameter for which an authentication or subscription user key/token has to be provided to perform requests

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 "list" giving one or more resources not supported by the Request builder for a given provider

headers

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

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)
