D8.2: Report on Technology Watch

The aim of this deliverable is to present a summary of the different technological approaches that EUDAT investigated to support the design of the prototype services and data models identified in D8.1 and implemented in task 8.2 (D8.3, data models) and task 8.4 (D8.4, service design and prototypes). This document presents the two distinct but related topics of investigation: the existing data models that could support the design of DLC models and a directive language, as well as the existing technologies to support the usage of graph-based data, workflow descriptions, directives, semantic resources and dynamic data. These descriptions are not meant to be exhaustive but reflect the results of our current state of knowledge.
