1 Introduction
1.1 re3data.org
Research data are valuable and ubiquitous. The permanent access to research data is achallenge for all stakeholders in the research community. The long-term preservation andthe principle of open access to research data offer broad opportunities for the researchcommunity worldwide. A growing number of universities and research centers are startingto build research data repositories allowing permanent access to data sets in a trustworthy
environment. Due to disciplinary and other requirements, the landscape of research datarepositories is very heterogeneous. Thus it is difficult for researchers, funding bodies,publishers and scholarly institutions to select appropriate repositories for finding and storing
research data.
re3data.org is a global registry of research data repositories (RDR) that covers researchdata repositories from different research disciplines. It presents repositories for thepermanent storage and access of research data sets to researchers, funding bodies,publishers and scholarly institutions. Beginning in 2016, re3data.org is a service of DataCite1
promoting a culture of sharing, increased access and better visibility of research data.
DataCite is a global non-for-profit organization that is actively involved in several initiatives
to improve the availability and citation of research data via the Internet.
The registry was developed within a research project of the same name and went online
in autumn 2012. It was funded by the German Research Foundation (DFG)3 in two project
phases, the first from January 2012 until December 2013. The current funding period started
in January 2014 and will last until December 2015. Project partners in re3data.org are theBerlin School of Library and Information Science at the Humboldt-Universität zu Berlin4, theLibrary and Information Services department (LIS) of the GFZ German Research Centre forGeosciences5, the KIT Library at the Karlsruhe Institute of Technology (KIT)6, and the Librariesof the Purdue University7. The German project partners are actively involved in the German
Initiative for Network Information (DINI)8 and current research data management activities.
re3data.org cooperates, among others, with BioSharing9 and OpenAIRE10.
In March 2014, re3data.org merged with Databib, a similar initative at Purdue University(West Lafayette, Indiana, USA). The aim of this cooperation was to serve the research1

1.2 The Metadata Schema
The re3data.org metadata schema contains metadata properties describing a researchdata repository such as its general scope, content and infrastructure as well as its
compliance with technical, quality and metadata standards. The schema includes required
metadata properties and optional properties providing additional information. The schemaserves the purpose of: recommending a standard for describing a research data repository;
 providing the basis for interoperability between research data repositories andre3data.org;
 helping data repositories move towards shared standards and practices.
To facilitate the selection process of appropriate research data repositories re3data.org
developed a series of icons. The icons are displayed for a respective entry if an RDR provides
important information concerning the repository, e.g. if it complies with a certificate or
supports the provision of persistent identifier systems.
The initial version of the schema (formerly called vocabulary) was developed and tested
on 20 randomly chosen repositories. The sample originated from a list of 400 research datarepositories. These findings, as well as suggestions from project partners, led to version 1.0.
After its publication in July 2012 the re3data.org project team issued a public request forcomments that led to substantial changes in the structure of the schema. Version 2.0 of theschema synthesizes all the responses as well as current developments in the realm of
research data repositories. Versions 2.1 and 2.2 introduced minor changes, as well as there3data.org Registration Policy explaining. The current version 3.0 includes changes of there3data.org Registration Policy as well as structural adjustments on the schema to betterreflect changes within the landscape of research data repositories.

Future developments of the schema will also rely on the feedback of the research datarepository community. This open and transparent development process is to ensure a strong
basis for a future standard for describing research data repositories that is supported by androoted in the community. re3data.org appreciates your continuous feedback and invites you
to share ideas for future developments of re3data.org.

1.3 re3data.org Registration Policy
The major aim of the registry is to improve the visibility of research data repositories
irrespective of its type or disciplinary scope. A research data repository is a subtype of asustainable information infrastructure which provides long-term storage and access toresearch data. Research data means information objects generated by scholarly projects forexample through experiments, measurements, surveys or interviews.
A research data repository listed in re3data.org is either:a data provider primarily offering research data and its metadata (ideallyexposing metadata via application programming interfaces),ora service provider primarily harvesting metadata of research data from data
providers as a basis for building value-added services, e.g. a portal.

To be registered in re3data.org a research data repository must comply with thefollowing minimum requirements:
A repository has to have focus on research data; be operated by a legal entity with an organisational framework that provides
sustainability (e.g. library, university); clarify access conditions to the repository and research data; and provide terms of use.

1.4

Research Data Repository Registration Workflow

Anyone can suggest research data repositories to be listed in re3data.org via an
application form providing information such as the name and URL of the RDR.15 The
information is reviewed and enhanced by an editorial board who analyze the website of the15

RDR using a handbook that gives practical information on how to obtain the metadata
properties of the re3data.org schema. A repository is indexed when the minimum
requirements of the re3data.org Registration Policy are met. Before a new record of an RDR
is published in re3data.org all gathered information is reviewed by a second editor.
To update a re3data.org entry the operator of a respective RDR can use the web formsuggesting additions and/or changes on the entry. After a review by the re3data.org editorial
team, the entry will be updated.

3 re3data.org Metadata Properties
The table below provides a detailed description of the re3data.org properties that
describe a research data repository registered in re3data.org. For an example of how theproperties are expressed in XML format, please see the XML example provided (see section
3).
A naming convention has been used for all properties and attributes as follows:
properties, attributes and child properties begin with a lowercase letter. If the name of theelement consists of more than one word, subsequent words begin with capital letters. The
indicator A/C shows whether the property being described is an attribute (A) or a child (C) of
the corresponding property that has preceded it.
The attribute Occurrence (Occ) explains if a property can have multiple instances, whichis indicated by the notation: Occ. 1‐n, meaning that a property must occur once (1), and may
occur multiple times (n). "Req" indicates that an attribute is required if the corresponding
property is applied. The terms of the "Controlled Vocabulary" are regulated by there3data.org team. The values of the controlled vocabularies are explained and defined in the
appendix (4.1). The primary language for all metadata is English. Other language descriptions
can be added as additional information.

disciplinary

Disciplinary repository (Subject repository):"This is a collection of research outputs with a common link to aparticular subject discipline. Subject repositories are likely to cover one
broad-based discipline, with contributors from many different
institutions supported by a variety of funders; the repositories
themselves are likely to be funded from one or more sources within thesubject community. Although for some subject repositories the funding
may be fragile, if they are of enough importance to the community
16
then funding crises are usually weathered."

governmental

Governmental Repository:
This is a collection of outputs from projects and programmes related togovernmental institutions. The repository is primarily supported by afederal agency. These repositories are likely closed for external
contributions.
Multidisciplinary Repository:
This is a collection of research outputs serving multidisciplinary needs.
These repositories cover several research disciplines. Contributors frommany different institutions and communities are likely accepted.

Institutional Repository:"This is a collection of research outputs with a common link to aparticular institution, usually by authorship. These repositories arelikely to cover more than one research discipline, to have funders inmany if not all the Research Councils and support communities who
have different approaches to research dissemination. Whether depositof content is mandatory is a decision that will be made by each
institution. The institutions may have many requirements for thecontent of the repository, from open access dissemination, throughmetrics, marketing to strategic planning. It is likely that many of theseprocesses in the past were undertaken through collection of
17
bibliographic information."
Project-related Repository:
This is a collection of research outputs with a specific focus on the
research data resulting from particular research projects. All
contributions must be linked to the particular project, mission, etc.

5.4 Explanation Of re3data.org Access Types
The policies and access control measures of a research data repository regulate anumber of issues, particularly: Who can access the research data repository? Who candownload research data and how can the user reuse these research data from therepository? And who is permitted to deposit research data? To describe such accessregulations of a research data repository, re3data.org differentiates between three
categories representing different levels of access. First there is the access to the researchdata repository defining who can access the database in general, e.g. searching therepository requires a membership. Secondly there is the access to the research data sets in
the research data repository in particular, e.g. being able to download data from therepository. Thirdly there is the access to upload and deposit research data sets to theresearch data repository. The access to each level can be open, restricted and/or closed.
Open means that there are no access barriers. Restricted means that external users canovercome access barriers, e.g. by creating a user account. Closed means external users
cannot overcome access barriers. Embargoed access means that external users cannot
overcome access barriers until the research data are released for open or restricted access.
The last stated access type applies only to the level of access to the research data sets.
As shown in the matrix below the access to the research data repository is the basic level
to define the general framework of access to the actual research data sets, e.g. a researchdata set in a research data repository that is restricted through registration cannot be open
but just restricted or even closed; a research data set in a closed research data repository
which underlies access restrictions that cannot be overcome by external users is neither
open nor restricted but only closed. Thus to define the general accessibility of a researchdata repository the values highlighted in orange are needed (values in braces can occur).
