Wales produces their OCDS data via conversion from the TED / OJEU format following the instructions set out in the OCDS for the European Union Profile. They make use of the OCDS for the European Union Extension to publish this information.

Data quality

The dataset has quality issues to take into account, notably:

  • There are sometimes organization references without associated entries in the parties array.
  • Organization identifiers are not globally unique and cannot be linked to other datasets.
  • There is a small number of blank or empty fields in the data which should not interfere with most use cases.
  • Release id’s are linked to the release package they are contained within. Releases with identical information can have different release id’s if they were downloaded in different packages.

Access data

This OCDS dataset is available for download in JSON, Excel or CSV format. You can download the data for contracting processes in a specific year or for all time.

JSON

Each contracting process is represented as one line of JSON text in the .jsonl file.

The .jsonl file is compressed using Gzip. Windows users need 7-Zip, WinRAR or WinZip to decompress the .gz file.

Excel

Each contracting process is represented as one row in the main sheet. Other sheets link to it via the _link_main column.

Excel files can have at most 1,048,576 rows. If a year is missing, it had too many rows. Download the CSV files, instead.

CSV

Each contracting process is represented as one row in the main.csv file. Other files link to it via the _link_main column.

The .csv files are archived using tar and compressed using Gzip. Windows users need 7-Zip, WinRAR or WinZip to decompress the .tar.gz file.
