Data sources

Data sources are the core elements of Qalita, they are referenced in the platform, the data are never copied and stored in the platform.

Add a source

Adding a source is currently only possible via the command line qalita.

When you add a source, it creates a qalita-conf.yaml configuration file in the ~/.qalita/ folder, which contains the source connection information.

Example:

version: 1
sources:
- config:
    path: /home/aleopold/desktop/data/heart/
  description: 11 clinical features for predicting heart disease events.
  id: 1
  name: Heart Failure Prediction Dataset
  owner: admin
  owner_id: 1
  reference: true
  sensitive: true
  type: file
  validate: valid
  visibility: internal

In this example, the source is a local file, but it could be a database, a remote file, a data stream, etc.

Property	Description
version	Configuration version
sources	List of sources
config	Source configuration, properties vary according to source type.
Unique source identifier, obtained by the platform after finalizing source referencing with the qalita source push command.
name	Source name
owner	Name of user owning the source
owner_id	Identifier of the user who owns the source
type	Type of source
If source is a reference, allows comparison with other sources.
sensitive	If the source is sensitive, special authorization is required to access it see authorizations
validate	If the source is valid, this means that the customer has access to the source, and it can be referenced on the platform.
Visibility of source, can be public, internal or private. Restricts access to different user profiles on the platform.

Source types

Sources can be of any type, as long as packages are available to handle them. QALITA Platform provides no limitations on source types.
