Products Overview

The Research Object Digital Library (RODL) realizes the backbone services of Wf4Ever software architecture for the preservation of research objects. The main interface of RODL is a set of REST APIs, among which the two primary ones are the RO API and the RO Evolution API. RODL can be used as the backend of different client applications. For instance, the development version of myExperiment has used it as a backend for storing packs. The reference client of RODL is the RO Portal, developed alongside RODL to test new features and expose all available functionalities. The design decisions included:

  • Modular system implementation: RODL has been implemented using a modular approach, which allows a more flexible maintenance, extension, integration and interoperability.
  • Implementation of well-defined and well-documented interfaces, which provide a suitable basis of interoperability
  • Native RO support. RODL was implemented alongside the RO model. 

Vision by the end of the project

Vision

Icon

RODL+RO Portal will provide support to RO management for high quality preservation in Digital Libraries, to be demonstrated in a concrete scenario for a vertical sector.

RO Portal and RODL allow users to create, manage and publish their Research Objects, change their evolution state and make sure they are long-term preserved. RODL is a common repository for different client applications, e.g., myExperiment, RO Portal, RO Manager.

Main features of RO Portal by the end of the project:

  • Search for ROs using keywords or facets
  • Create and inspect ROs, aggregate resources
  • Create annotations about any resource:
    • Basic interface for common annotations (description, comments, etc)
    • Advanced interface for other
  • Create snapshot/releases, see versions and history of changes
  • Access several RO services (quality evaluation, recommendations, etc.)
  • Monitoring & notification of RO events
  • Authentication of users and their actions, basic access control
  • Secure storage – the resources will never be lost or damaged
