Introduction

In the era of data-driven applications, the need for a more flexible, secure, and decentralized approach to data management is more pressing than ever. The Data-Driven Manifesto aims to shift the paradigm from application-centric to data-centric architectures. One technology that aligns closely with this vision is Decentralized Web Nodes (DWN). In this article, we’ll explore how DWN can serve as a building block for data-centric architectures, focusing on its permission layers, authorization mechanisms, and the concept of protocols.

The Data-Driven Manifesto: A Quick Recap

The Data-Driven Manifesto advocates for a change in how we handle data. Instead of locking data within specific applications, the manifesto suggests creating data-centric layers that expose data to multiple applications. This allows for data to be reused across different platforms.

The guiding principles of the manifesto are that data should be:

  1. Data is a key asset of any person, organization, and society.
  2. Data is self-describing and does not rely on an application for interpretation and meaning.
  3. Data is expressed in open, non-proprietary formats.
  4. Access to and security of the data is the responsibility of the enterprise data layer or the personal data vault, and not managed by applications.
  5. Applications are allowed to visit the data, perform their magic and express the results of their process back into the data layer.

The FAIR principles

  1. Findable: Easy to locate and identify.
  2. Interoperable: Capable of being used in different systems.
  3. Accessible: Easily retrievable.
  4. Reusable: Capable of being used for various purposes.

The Role of DWN in Data-Centric Architectures

AUTHORIZATION AND PERMISSION LAYERS

One of the key features of DWN is its robust authorization and permission layers. These layers allow users to define who has access to what types of data. This is crucial for data-centric architectures, as it enables controlled data exposure and sharing. For instance, you might want to share certain data with social networks but keep other data restricted to specific users or applications.

PROTOCOLS: THE HEART OF DWN

DWN operates on an open protocol that has its own specifications. What sets it apart is its ability to support application-specific protocols. These protocols can manage data access, roles, and even the structure of requests and responses. By leveraging these protocols, you can model your application and data-centric logic to make data more interoperable and accessible.

STRUCTURED DATA AND SCHEMAS

DWN also supports the hosting of structured data, complete with corresponding schemas. This feature enhances data accessibility and reusability, as structured data is easier to manipulate and understand.

Challenges and Future Directions

While DWN offers a robust solution for data-centric architectures, it’s not without challenges. One of the major hurdles is data discovery. Although DWN allows for data to be distributed via decentralized nodes, finding that data remains a challenge the community needs to address.

Conclusion

DWN serves as a promising building block for data-centric architectures, aligning closely with the principles of the Data-Driven Manifesto. Its permission layers, authorization mechanisms, and support for application-specific protocols make it a versatile tool for managing data in a decentralized manner. As the technology matures, it can revolutionize how we think about and handle data.
