The development of the ENVRI Reference Model provides the ESFRI Environmental Research Infrastructures with a common ontological framework for description and characterisation of computational and storage infrastructures, and provides them a community standard to help achieve greater levels of interoperability between their heterogeneous resources.
With limited resources, only few examples are included; these will be extended when more resources are available for future investigations.
How to Use the Guideline
A collection of examples demonstrating usage of the ENVRI Reference Model is given below. Different examples may serve different purposes. Some of them merely illustrate a different way of using the reference model (e.g., Example 5), while others also intend to introduce model concepts where many terms are highlighted with clickable links. Please click those highlighted concepts that will re-locate you to the related definitions and specifications in the Reference Model. Be sure to go through all terms marked with -- some of them, though repeated, will guide you to a different part of the model. By visiting all linked contents, you will have explored 90% of the most important model content. (Note, terms marked with are also model concepts which link to content you might have visited before.)
Examples of Using the Reference Model
Example 1: Using the Reference Model to guide research activities (EISCAT 3D - EGI)
Example 5: Using the Reference Model to drive implementations of common services (WP4 practices)
Using a number of examples, we have shown that by using the Reference Model, a ESFRI ENV RI could benefit from:
- A set of ready-to-use terminology with a publicly-accessible reference base, which can be used to describe requirements and architectural features of an infrastructure, and serve as a common language in communication materials; in particular, with an external community without any specific knowledge of the scientific domain being addressed.
- A uniform framework with well-defined subsystems of components specified from different complementary viewpoints (Science, Information and Computation), which promotes structural thinking in constructions of system architectures, and can be used as a research tool for comparison and analysis of heterogeneous infrastructures.
- A knowledge base capturing existing requirements and state-of-the-art design experiences. The information provided can be referred to in various system analysis tasks, to guide design and implementation activities, and to drive the development of common services.
When future resources become available, we will conduct more investigations, including:
- We will assist our users to get hand on the Reference Model and exploit new ways of using it.
- We will assist the development of the common services.
- We will use the Reference Model to bridge ESFRI ENV RIs with external communities (such as, RDA), projects (such as, GEOSS, DataOne, EUDAT and EGI), and standards (such as, INSPIRE, OGC, and the Digital Library Reference Model). These will provide ESFRI ENV RIs an overview of related technologies, and possible solutions for the integrations.
- We also have a plan to experiment with the Reference Model as a guide to train the next generation data scientists.
