Website

The website of DBnomics is available at https://db.nomics.world/.

It allows users to browse and download time series.

URL structure

The website URLs are designed to reflect the structure of the data, remain human-readable, and be easy to share.

Here are the main URLs used for browsing data:

• https://db.nomics.world/{provider_code}: provider page
• https://db.nomics.world/{provider_code}/{dataset_code}: dataset page
• https://db.nomics.world/{provider_code}/{dataset_code}/{series_code}: series page

You can navigate up the hierarchy by removing the last segment of the URL: from series to dataset, then from dataset to provider.

These datasets are often organized by the provider in a category tree, as shown in the screenshot above.

Dataset page

This page shows the series of a dataset and allows users to filter them by dimensions.

Filter by dimension

You can filter the series of a dataset by their dimensions (e.g. Country=France, Frequency=Quarterly, etc).

Note

This search pattern is often called faceted search and is commonly used on e-commerce websites to find products by criteria like size, weight, color, etc.

Here is the dataset CEPII/BACI_HS17, with the dimension "Exporter" set to "France". The number of series matching this criterion is shown:

Full-text search

It is also possible to do a full-text search on the series belonging to the current dataset (as opposed to the search of the home page which targets the whole database).

Download series

Limitations

Downloading series from the website requires a user account.

Due to technical limitations, it is not possible to download more than 1000 series at once from the website. If you want to download more series, please use the Web API.

Click on the "Download" button to open a menu and select "Excel file" or "CSV file".

Downloading series from the website is useful for one-off exports, but you need to start the download again manually each time you want fresh data. With the Web API and its clients, you can automate retrieval and updates of your time series directly from your preferred environment (e.g. Python, R, etc.).

Series page

Each time series has its own URL, allowing it to be displayed as a chart or a table, and making it easier to reference.

Here is the page of the time series ECB/EXR/A.ARS.EUR.SP00.A:
