Differences between the 1.1 and 2.1 WDDS versions

Initial modification

...

• .

...

...

• "title" has been renamed to "label" on the root-level

• “updated” is used instead of “lastUpdateDate”

• All non-standard properties (datasetID, language, agency, description, status) have been moved inside “extension” section

• The standard “status” property has been updated to include any metadata information at the observation level

• The possible values of “class” have been updated to include the “dataset” response instead of “bundle” (“bundle” was an accepted value before version 2.0)

JSON-stat modifications

• JSON-stat 2.0 support in WDDS:

  • The “version” property has been added with the value “2.0”

  • The “id”, “size” and “role” properties have been moved from the dimension level to the dataset level

• JSON-stat status property:

  • The “status” property is not displayed in case it contains no information

• JSON-stat error message change for too voluminous extractions:

  • “Too many categories have been requested. Maximum is 50" error message is displayed in case the extraction to be retrieved is too big. It replaces the previous error message “Maximum 50 datasets can be retrieved at a time” or the response of the query builder “Maximum 50 sub-indicators can be retrieved at a time. Please filter your selection”

• JSON-stat error specification:

  • the communicated error message is in JSON format instead of plain text. The error elements are:

    • status: The HTTP status code

    • id: The provider’s internal error code (optional)

    • href: A link to a web page where information about this error is published (optional)

    • label: A short descriptive text about the error

Example:

{ "error": [\{"status": 400,"id": 100,"label": "NO_RESULTS: No data found"}]}

• JSON-stat HREF element contains all parameters:

  • The HREF property at the root contains the URL of the request

• JSON-stat “updated” property contains a date instead of timestamp:

  • if no time is specified, the value of "updated” should contain a date and not a timestamp with 0 values set for time

• JSON-stat “source” value is “Eurostat”, instead of “ESTAT”.
