Open Access: consists of the on line access to academic information with no registration, subscription or payment requirements for the reader. In R & D context, Open Access typically focuses on access to scientific information, to two main categories: literature (papers, thesis, proceedings, etc.) and research data (they are the empirical basis of publications and / or raw data).

Self-archiving: is the final version of the published article or the final manuscript after the peer review which are filed by the researcher in an open repository before, during or after publication.

CERIF: it is a recommendation for all member states of the EU and it has been developed with support from the European Commission. Stands for Common European Research Information Format, and is a standard, created by EuroCRIS for managing and sharing information on researchers, organizations, projects and funding. At the beginning it was based on projects, people and organizational units. Later evolved to suit other information sharing needs of research information systems and many other entities came out and joined to CERIF data model.

COUNTER:  Stands for Counting Online Usage of Networked Electronic Resources and are European Directives for gathering statistics on resources made available via interconnected repositories. Their objective is to guarantee, through the use of standards and protocols (Codes of Practice), that the statistics reports obtained from the various repositories are credible, compatible and coherent.

Creative CommonsAre licences that enable creators to maintain their copyright while also allowing others to copy, distribute and make certain uses of their work, at least for non-commercial purposes. There are a total of six types of Creative Commons licence.

DAIStands for Digital Author Identifier. This is a unique number assigned to each author who has been appointed to a position in a Dutch University or Research Institute or has some other relevant link to one of these organisations. The DAI uses various different ways to write the name of the author and is used to distinguish between authors with the same name.

DOAJ: stands for Directory of Open Access Journals. It is a free service that provides open access to Open Access journals peer reviewed.

DOIStands for Digital Object Identifier. This is a specific number than can be used to locate a specific article (publication) on the network. The DOI system is static, even when the article is relocated to a different address, because it includes information in the form of metadata.

D-NET: open source software tool developed for the construction and maintenance of infrastructure data.

DRIVER: Stands for Digital Repository Infrastructure Vision for European Research. This is an EU project that is creating a technological and organisational working framework for implementing a pan-European layer of data to enable the advanced use of resources in the field of research and higher education. DRIVER is developing a service infrastructure and a data infrastructure. Both are designed to organise the resources and services that exist in the repositories network.

Dublin Core: it is one of the earliest and accepted by the international community metadata standards. This system is used in the description of digital records hosted in repositories. It is chosen as the metadata format for the registry of DRIVER repositories. This standard establishes a pair set of type / value.

Dulcinea: it is a national project. Its goal is to reveal the publishing policies of Spanish magazines regarding access to their archives, copyright entitlements over the same and how they could affect their subsequent self-archiving in institutional or thematic repositories.

Embargo: it is the period established by the publisher, during which a document may not be available in Open Access.

E-print: it is the digital version of a research paper (journal article, thesis papers, book chapters, books) accessible online. When it comes to journal articles, the term e-prints covers pre-prints (before the peer review) and post-prints (after the peer review).

Impact Factor: it is a quantitative tool related to the frequency of citations of journal articles. It is annually calculated and it´s known through the Journal Citation Reports (JCR) of the Web of Science (WoS).

IRUS-UKStands for Institutional Repository Usage Statistics. This is an aggregation service for concentrating statistical data on the use of all content downloaded from institutional repositories in the United Kingdom.

JISCStands for Joint Information Systems Committee. This is the institution responsible for promoting innovation, education and research in the United Kingdom. The JISC is aimed at defending the use of digital technology in the United Kingdom.

Knowledge ExchangeCooperation between the Denmark’s Electronic Research Library (DEFF), the German Deutsche Forschungsgemeinschaft (DFG), the Dutch SURF Foundation (SURF) and the Joint Information System Committee (JISC) of the United Kingdom. They propose the KE Usage Statistics that form European Directives on the gathering and treatment of statistics on the use of interconnected repositories.

OA-Statistikis the system for gathering statistics on the use of documents stored in institutional repositories in Germany, promoted by the Deutsche Forschungsgemeinschaft (DFG). 

OpenDOAR: stands for Directory of Open Access Repositories. It is a directory of Open Access repositories. It is offered as a Sherpa service, a University of Nottingham project.

ORCID: stands for Open Researcher and Contributor ID. It is a non-profit organization with the aim of providing a registry for unique researcher identifiers and a transparent method of linking research activities and outputs to these identifiers. It provides two basic functions: registry to obtain a unique identifier and support for communication and authentication between systems.

PIRUSStands for Publisher and Institutional Repository Usage Statistics. This is a statistics gathering tool developed by the JISC.

RepositoryIs a database of scientific publications that enables the institutions that manage them (universities and R&D centres) to contribute to Open Access by offering the chance to consult the content of said repositories via the Internet.

Resource: it is each one of the open access infrastructure harvested in RECOLECTA. The resources can be institutional repositories, thematic repositories, journals portal or journals. Most of the harvested resources in RECOLECTA are institutional repositories, this is the reason why these two terms can be interchangeably.

Institutional Repository: it is the repository that harvests scientific publications from its own the staff. This category includes universities, research centers, hospitals, public and private foundations, and autonomous regions.

Thematic Repository: it is the repository that harvests the scientific publications of a particular subject area or a particular discipline.

Peer Review: it is the process of evaluation and certification of research quality and its results, done by experts in the field, before its publication in scientific journals.

Sherpa/Romeo: is one of the services offered by Sherpa, a project being led by the University of Nottingham for the development of institutional Open Access repositories at universities for the purpose of facilitating the swift and efficient distribution of research.

SUSHI: Stands for Standardised Usage Harvesting Initiative. This is a standard protocol for automating the management of electronic resources in usage statistics in COUNTER format. It can also be used for reports in other formats that meet the specific requirements for recovery by SUSHI.
