Data Space

PGTEC Data Space

The PGTEC data space is a climate and hydrometeorological data space designed to share information between organisations in a governed and interoperable way. It is not just a file repository, but an infrastructure where data, models and services can be exchanged under clear rules for access and quality.

This section explains the role of the data space inside the project and serves as an entry point to the rest of the technical documentation.

What is the PGTEC data space?

The PGTEC data space connects organisations that:

  • Produce climate, hydrological and meteorological data
  • Exploit that data for prediction, risk analysis and early warning services
  • Need guarantees about governance, traceability and responsible use of information

Some key principles of the data space are:

  • Semantic interoperability
    Data is represented using common information models, based on Smart Data Models, so that different systems can understand each other.

  • Technical interoperability
    Data exchange happens through standardised APIs and components, using FIWARE and NGSI technologies.

  • Governance and trust
    Participants are identified using cryptographic identifiers and, progressively, verifiable credentials that describe their roles and permissions.

  • Service orientation
    Besides raw datasets, the data space exposes processing flows, models and services that can be directly integrated into external applications.

Main building blocks

The PGTEC data space is built on several functional blocks, each described in its own section:

  • Data Sources and Services
    Description of climate and hydrological data providers, their variables, frequency, coverage and usage conditions.
    See Data Sources and Data and services.

  • Common information models
    Shared data models for forecast series, observations and streamflow, based on Smart Data Models.
    See Smart Data Models.

  • Data Flow and processing
    Ingestion, normalisation, historical storage and publication of data, implemented with SmartFlow and FIWARE components.
    See Data Flow and SmartFlow.

  • Identity, trust and access
    The identity layer of the data space, where participants, their identifiers and the credentials that control access are managed.
    See Identities and verifiable credentials.

How to use this section?

If you are new to PGTEC and want to understand its data space, a reasonable path is:

  1. Read this introduction.
  2. Review the data space architecture to see the key components and how they interact.
  3. Dive into identities and verifiable credentials if you are interested in access and trust.
  4. Go to Join data space to see the planned steps for onboarding as a participant.
