The main element for interacting with a Data Space is a connector. A data connector allows access to the functionalities offered by a Data Space through a web interface. These data connectors must comply with certain rules to ensure interoperability, meaning the coordinated, secure exchange of data under a standard.

In this post, we will visually explain how to work in a Data Space through the web interfaces that a connector based on the IDSA standard offers us. This data connector has been developed by ITELLIGENT within the framework of a research project.

We assume that the Data Space infrastructure is already operational, and we will see step by step how to interact with it, whether you want to share data with the Data Space (Data Provider) or access third-party data in the Data Space (Data Consumer).

DATA PROVIDER: HOW TO USE THE CONNECTOR TO SHARE OUR DATA WITH THE DATA SPACE

Suppose we have a data source that we want to share through the Data Space (Data Provider), how will we use the data connector for this? We will need to perform the following three steps:

STEP 1. Define the data source to be shared. The first thing we need to do is add the data sources in the Data Space connector.

STEP 2. Establish a Usage Policy. We must establish a Usage Policy for the dataset that we are going to make available to third parties. This can be done through the Data Space connector, which allows us to interact via a web interface. For example, in this video, we show how this data connector works and how to generate a Usage Policy for the data we will offer to the Data Space:

STEP 3. Create the data offer. In this third step, the data offer is created, which will then be available through the Data Space. Here, we show you how to generate the data offer from the data connector:

DATA CONSUMER: HOW TO CONSUME THIRD-PARTY DATA THROUGH A DATA SPACE CONNECTOR

When consuming data, a connector offered by the Data Space is necessary. This data connector has a unique identifier that can control what you do and check everything you do within the Data Space. Once we have an established data connector, we will show how to access third-party data to consume it (Data Consumer).

To do this, we explain how it works in this video:
