Here you can find the deliverables that we are producing as part of the EVER-EST project were we cover the whole process that we carried out to generate awareness of research objects and their benefits that they bring to earth scientists (D4.1), the requirement analysis and the extensions to the research object model to adapt it to observational disciplines (D4.2), and the tools that we developed to guarantee the reuse of research objects and their quality assurance, and the design of a new research object lifecycle where Digital Object Identifiers DOIs play a central role (D4.3 and D4.4).
This document introduces the Research Object (RO) concept into the Earth Science Virtual Research Communities (VRCs) of the EVER-EST project. An overview of the main concepts, tecnologies and models related to research objects is provided along their contextualization and extension under the light of a set of initial requirements elicited from the VRCs about the representation of such objects, their lifecycle management, and exploitation through the EVER-EST VRE. This work has been conducted in close collaboration with WP3 and WP5 partners, and establishes a link between the requirements of the user communities and the technological solutions provided by the VRE infrastructure around the notion of research objects, respectively. The outcomes of this analysis provides the basis for the implementation of the subsequent tasks of WP4 and are expected to evolve over time during the rest of the project, taking into account the continuous software development and integration model that is applied.
Deliverable D4.1. produced an analysis of the main concepts related to research objects under the light of the initial requirements elicited from the EVER-EST VRCs. This analysis enabled the understanding of the necessary adaptations, customizations and extensions of research object methods, tools and models to a new domain such as Earth Science disciplines and showed the way for future work in the project. This document focuses on the latter of such areas, workflow and research object models, and introduces the necessary extensions and customizations that have been implemented in the research object models and vocabularies for Earth Science. In addition to the final ontologies this document provides an overview of the methodology followed, including further analyses and the joint work carried out with the EVER-EST user communities in WP3 and technical partners in WP5 and WP6. Throughout this work, it has been sought to leverage the familiarity of the Earth Science community with existing resources, maximizing the reuse of existing terminology and metadata used in the field and ensuring the compliance of the newly introduced terms with existing standards and potential future extensions. In doing so, it is sought to facilitate adoption, reducing the learning curve. This work also pushes the boundaries of the generic models available for research object representation and produces significant contributions and extensions to their specification. Furthermore, a new branch has been created specifically for the Earth Science disciplines, which provides specialized modeling support for research objects in such scientific areas.
One of the main motivations of research communities in EVER-EST to integrate the research object model in their scientific process is to enhance sharing and reuse of their scientific results. The research object model enables knowledge sharing and reuse; its foundations, including the common ontology and the data model, ensures data interoperability and reusability. Nevertheless, the model needs to be integrated in an ecosystem of tools that provides mechanism to search and explore research objects, assess their quality, and properly credit the authors when their research objects are reused by other scientists.
This deliverable describes the first release of the components that make up the ecosystem of tools complementing the research object model. These components include retrieval mechanisms to support search and exploration of research objects, checklists designed in cooperation with VRCs to assess the quality of research objects in Earth Science, digital object identifiers DOIs to uniquely and permanently identify research objects, and tools to keep track of citations of research objects in scholarly communications.
One of the main goals of the EVER-EST project is to implement the research object model, and an ecosystem of tools supporting this model, in earth sciences to foster the sharing and reuse of scientific results, and to ensure their preservation in the long term. The research object model supports knowledge sharing and reuse mainly using a common vocabulary described using a web standard data model specifically designed for data interchange, and a rich knowledge representation language. The model supports the definition of data access levels and copyright information.
This deliverable describes the components that complement the research object model mainly enhancing the research object findability, traceability, and quality monitoring. The research object findability is improved by the semantic enricher process that generates metadata that describes its content. The metadata is used in two complementary retrieval mechanism: a semantic search engine to find research objects and a recommender system that helps to explore the research object collection including the social dimensions of the research activity. The traceability is implemented with Digital Objects Identifiers that are integrated in the research object lifecycle, with the additional benefit that authors can receive proper credit for their work. Finally, the quality of research objects is assessed through custom checklists designed with the help of the Virtual Reaserch Communities. These checklists are run regularly and there are available tools to monitor the assessment variations through time so that decaying research objects can be intervened if necessary.
