Import a dataset
You can create a dataset on the dashbord or on the datasets pages.
Three differents datasets on Data Fair.
- Upload a file from your computer
- An editable dataset
- Metadata dataset
- A virtual dataset
Upload a file
You can import files using any Create a dataset action buttons on Data Fair.
The upload file process contains a list of the formats supported by Data fair. It is possible to add attachments in a zip archive to link it to the rows of the dataset.
Once the file is loaded, you are redirected to the dataset edit page. Data Fair continues processing the file on the dataset edit page.
Six have to be validated to use your dataset :
- Conversion to a format used by the platform internally.
- Analysis, which will determine the schema of the dataset.
- Indexing, which will allow you to quickly find and access the data in the file.
- Enrichment, which supplements the data in the file with external data.
- The Finalization, which corresponds to the last processing before the dataset is available.
When finalization is complete, the dataset state is set to "available". It can then be edited, enriched or used in the various visualizations.
An editable dataset is an empty editable dataset created without a data file.
You will be able to define the columns of the dataset and then add the rows from Data Fair.
Each column is defined by its label and its type.
The schema of your editable dataset is defined when you have filled in all the columns of your dataset.
Add columns to create your editable dataset
You can then add rows to your dataset either through a form on a page of your site, your portal or through the Data section in the edit of the dataset.

A metadata dataset does not contain data.
It can be used to contain a set of files such as PDFs, images or videos.
Images can then be used on your portals as thumbnails for the datasets or used with their links.
Attachment descriptions can contain rich text in Markdown format for better formatting.
A virtual dataset is a view of one or more datasets (children's dataset).
It is used to present a portion of a dataset or to concatenate datasets with the same schema.
For exemple, it is possible to create a view of its municipality or its department on a national reference dataset without having to copy the data.
As a virtual dataset is a portion of a dataset, when the reference dataset is updated, the virtual dataset of the town (or department) will also be updated. The data always remains up to date with respect to the reference data set.
