Transaction Web Service
Contents
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.codelist.Codelist=SDMX:CL_BAR(1.0)", "urn:sdmx:org.sdmx.infomodel.datastructure.Dataflow=AAA.SUB1:DF1(1.0)", "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)", ... ]
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 Note: More information is provided if authenticated |
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" }, ... ]
If the query is provided with correct authentication credentials of an administrator then the User ID of the user who performed the change is also returned. An example of this:
[
{
"Date": 1612358238673,
"Id": 449,
"User": "admin1",
"Action": "Replace",
"Type": "Structure Submission"
},
