Explain Plan Web Services

Overview

Note: this is the explanation for the Web Services in Fusion Registry version 10.

The Registry has the User Interface feature "Test Mapping" which can be used to test an input file against a Mapping. This feature is very useful when debugging why a mapping did not occur. This page details how to directly call the Web Services that perform the explanation of a mapping

There are 2 Web Services. The firsts "explains" what series dimensions of an input file would be mapped and which would be unmapped with regards to a specifc Map, the second analyses a particular Series Key.

'Explain Map' Web Service

From the supplied file and the specified mapping structure URN, returns a JSON object stating which series were mapped and which were unmapped from the input.

Entry Point	ws/secure/structuremap/explainmap
Access	Secure
Authentication	HTTP Basic Authentication
Http Method	POST
Accepts	SDMX-ML, SDMX-JSON or SDMX-EDI structure message
Content-Type	application/text or application/xml
Response Format	JSON object
Response Statuses	200 - Query Ok 400 - Missing Header 'URN' or Unrecognised file input 401 - Unauthorized 404 - Cannot resolve reference to Structure Map specified in URN parameter

HTTP Headers

The following header parameters must be specified:

HTTP Header	Purpose	Allowed Values
URN	(Mandatory) States the mapping structure to map the input data against.	A valid URN for a Mapping. E.g. urn:sdmx:org.sdmx.infomodel.mapping.StructureMap=MAPPING_TEST:SS_DF(1.0).DF_MAP_TEST

The output JSON object has 4 fields:

• source - the URN of the DSD or Dataflow that was used as the source of the mapping
• target - the URN of the DSD or Dataflow that was used as the target of the mapping
• mapped - a JSON object. Each field is a unique input key that mapped. For each field is a String stating what it mapped to.
• unmapped - a JSON Array of Strings showing which keys from the input were unmapped

Example Output

{
    "source": "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=MAPPING_TEST:DF_DSD1(1.0)",
    "target": "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=MAPPING_TEST:DF_DSD2(1.0)",
    "mapped": {
        "A:B:BEL": "AAAB:BEL:FIXED_EER",
        "A:C:BEL": "AAAC:BEL:FIXED_EER",
        "XXX:C:BAR": "AACC:BAR:FIXED_EER"
    },
    "unmapped": [
        "C55BCX:C:BEL"
    ]
}

'Explain Plan' Web Service

Given the supplied Key and Map, returns a JSON object stating the input, mappings and output for that series key

• Takes the parameters "dsd", "map", "key"

Entry Point	ws/secure/structuremap/explainplan
Access	Secure
Authentication	HTTP Basic Authentication
Http Method	GET
Response Format	JSON object
Response Statuses	200 - Success 401 - Unauthorized
