Get the connections between two hierarchies

Using the EBX5 metadata, calculates the grouping from parent to child group, based on codelist Identifier; as defined in 'EBXGroup.to' and 'EBXGroup.from'. This is a basic function of this package, it is exposed primarily for troubleshooting. Users will normally use ReadEBXHierarchy or ReadDatasetCodelists.

Usage

GetEBXHierarchy(sdmx_parent_codelist, sdmx_child_codelist)

Arguments

sdmx_parent_codelist

parent codelist name, in SDMX style.

sdmx_child_codelist

child codelist name, in SDMX style. Available code lists are shown by function GetEBXGroups in the field "Acronym". The actual group ID and location in EBX5 (branch, instance, code-list-name) are resolved using the Metadata structure.

Value

the resolved grouping details in the format int=parent list=(child1,child2, child3...)

Details

The solution may invaolve several steps (a list of group ID's), and may involve multiple step groupings, which have to be merged for the final result: MAJOR(306)->ODER(307)->FAMILY(302)->SPECIES(301) MAJOR(306)->ODER(307)->SPECIES(301) In the simplest case, if a matching group exists, list(ebx_parent_ID, ebx_child_ID) is returned
