Transaction Web Service

Overview

The Transaction Web Service provides access to all the structural metadata content of the Fusion Registry (including any content that has been subsequently deleted). A Transaction is the submission of a structure, group of structures or data registration.

Querying and Searching All Transactions

Returns a JSON Array of all of the structures in the Registry, filterable by parameter.

Entry Point	/ws/registry/tx/searchTransactions
Access	Public
Http Method	GET
Response Format	application/json
Response Statuses	200 - Submission Accepted

Response

The output shows the Date (as a millisecond epoch time), the Transaction Id, the action and the Transaction Type. A typical example:

 [
   {
     "Date": 1612434466642,
     "Id": 785,
     "Action": "Replace",
     "Type": "Structure Submission"
   },
   {
     "Date": 1612434448408,
     "Id": 784,
     "Action": "Replace",
     "Type": "Structure Submission"
   },
   ...
 ]

HTTP Query Parameters

If no parameters are supplied all transactions known to the Registry will be returned. If any of the filters applied below result in no results, an empty JSON response (HTTP 200) is returned.

Request Parameter	Required	Purpose
action	No	Filters the response to only include Transaction for the specified action. Legal values are Append, Replace, FullReplace and Delete.
dateFrom	No	Filters the response to only include Transactions from the specified time. The value must be specified as the epoch time in milliseconds (e.g. 1609459200000 is the start of the year 2021).
dateTo	No	Filters the response to only include Transactions up to the specified time. The value must be specified as the epoch time in milliseconds (e.g. 1609459200000 is the start of the year 2021).
max	No	Limits the returned response to only containing at most the specified value.
orderDesc	No	The default output is that Transactions are returned in a descending order (most recent first). Supplying false to this parameter reverses the order.
user	No	Filters the response to only include Transactions for the specified user.

Querying for all URNs

Returns a JSON Array of all the maintainable URNs (both current and deleted) in the Registry.

Entry Point	/ws/registry/tx/getAllUrns
Access	Public
Http Method	GET
Response Format	application/json
Response Statuses	200 - Submission Accepted

Response

An alphabetically ordered list of all of the URNs in the system. A typical example:

 [
   "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=WB:WDI_POVERTY(1.0)",
   "urn:sdmx:org.sdmx.infomodel.registry.ProvisionAgreement=BIS.LBS:TLBR_WS8_BIS_PH2(1.0)",
   "urn:sdmx:org.sdmx.infomodel.codelist.Codelist=SDMX:CL_BAR(1.0)",
   "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=AAA.SUB1:DF1(1.0)",
   ...
 ]

Querying for a specific URN

Provides information regarding who made changes to a particular structure. It returns the user id (and date, transaction id and action) of who last modified the maintainable with the given URN.

Entry Point	/ws/registry/tx/history
Access	Public
Http Method	GET
Response Format	application/json
Response Statuses	200 - Submission Accepted 400 - Illegal URN

Response

An ordered list of transactions (lowest transaction number first) of the transactions for the specified URN, showing the date, transaction ID and Action. A typical example:

 [
   {
     "Date": 1612358238673,
     "Id": 449,
     "Action": "Replace",
     "Type": "Structure Submission"
   },
   {
     "Date": 1612358239170,
     "Id": 450,
     "Action": "Delete",
     "Type": "Structure Submission"
   },
   {
     "Date": 1612358239657,
     "Id": 451,
     "Action": "Replace",
     "Type": "Structure Submission"
   },
   ...
 ]

HTTP Query Parameters

Request Parameter	Required	Purpose

Querying for a specific Transaction

For a specific Transaction ID, all of the structures can be requested for that Transaction.

Response Format	application/json SDMX
Response Statuses	200 - Submission Accepted

Response

The output will be in the format requested, showing all of the structures for the specific transaction. An example showing SDMX-ML 2.1 for a Dataflow:
