A
Abstract

In the abstract, you describe in a few sentences what you are publishing. The abstract should refer to the actual publication or research data. Therefore, please avoid using superordinate text passages, for instance from the project proposal.

Access restriction

DepositOnce is an open access repository. Therefore, its published items are public and freely accessible. In justified cases, however, it is possible to set a holdback period (embargo). In such cases, the metadata including the DOI is publicly accessible from the date of publication; the publication itself, however, is only available on the Internet after the embargo has expired.

Account

See Login.

Affiliation

During the submission process in DepositOnce, you will be asked to select your affiliation within TU Berlin. If your academic chair or joint project does not yet appear in the selection, please contact the DepositOnce Team so that the entry can be created. It is also possible to select several affiliations for a single item

Corrections

Digital objects once published in DepositOnce cannot be modified. However, a correction of the descriptive data (see Metadata) is possible. For this purpose, please contact the DepositOnce Team. New findings can be published in DepositOnce in the form of new versions (see Versioning).

Costs

Using DepositOnce is free of charge. Costs may be incurred if additional storage space is required (see Storage space).

Creative Commons license

Creative Commons licenses (often referred to as “CC licenses”) provide an easy way to grant the public rights of use. CC licenses are based on copyright regulations, but allow for a more extensive use of works than generally envisaged in copyright law.

  • Creative Commons Zero 1.0 (CC0)
    • You dedicate your work to the public domain by waiving all of your rights to the work, including all related and neighboring rights (to the extent allowed by law). Others may thus even use and distribute your material without attribution.
    • For research data, CC0 is usually recommended.
  • Creative Commons Attribution 4.0 (CC BY)
    • Users must give credit to the original creator of the work and state changes if any, including a URL or link to the original work, this CC license and a copyright notice.
    • For text publications, TU Berlin’s Open Access Policyexplicitly recommends researchers to publish them under a CC BY license.

D
Deletion

Once published in DepositOnce, digital objects are never deleted. Should a legally compelling reason be provided, online access to the digital object may be restricted. The digital objects nevertheless remain in the repository, and the descriptive information (see Metadata) remains publicly visible.

Deposit license

For content that is published and archived via DepositOnce, authors or editors must agree to a publishing agreement (also known as “deposit license”). This agreement regulates the rights and obligations of the creators and the University Library as operator of DepositOnce. With the deposit license, you grant the operators of DepositOnce non-exclusive usage rights to your publication or research data. These entitle the operators on a permanent basis to

  • make electronic copies of the digital object accessible to the public (upon expiry of the holdback or embargo period, if applicable) and, if need be, to convert the digital object into other formats in order to enable its display on future systems. This permission excludes content-related modifications to the digital object. This right applies to all types of use, whether currently known or not.
  • notify and transmit digital objects to third parties, for instance, as part of national collection mandates, particularly for the purpose of long-term archiving.
  • transfer agreed rights and obligations to another repository (for instance, any repository succeeding DepositOnce). This also entitles the DepositOnce operator to commission a third party to make the digital object available to the public (for example, through a facility specialized in the long-term availability of such objects).

Any printed or online publication of the research results – with amendments or in excerpts, if applicable – prior to, or after their publication in DepositOnce, remains entirely at your discretion as creator.

In addition, creators may grant an appropriate Open Content license, and thereby certain usage rights, to the general public. In accordance with its Open Access Policy, TU Berlin recommends the use of the Creative Commons license CC BY for scholarly publications. For more information see Licenses.

Dewey Decimal Classification (DDC)

In international contexts, the Dewey Decimal Classification (DDC) is the most widely used universal classification for classifying library items. It is mainly used in the English-speaking world and is of great importance for international data exchange. In DepositOnce, please choose one of the thousand classes of the third level of the DDC classification (cf. DDC overview of the German National Library).

Digital Object Identifier (DOI)

A Digital Object Identifier (DOI) is a persistent identifier for a digital object on the Internet (see Persistent identifier). A DOI is automatically assigned when you upload an item to DepositOnce. The DOI always refers to the whole item. For example, if you upload a zip file, a DOI will be assigned to the entire zip file — and not to the individual files.

Dissertations

Detailed information on publishing dissertations in DepositOnce can be found on the pages of the University Library Dissertation Service.

Documentation

An accompanying description of research data is essential for potential subsequent use. Therefore, please attach a so-called README file in .txt or .md format when submitting your dataset to DepositOnce. It may contain, for example, the following information:

  • Details on the collection of research data, such as:
    • Who collected the data?
    • For what purpose was the data (originally) collected?
    • What method was used to collect the data?
    • When and where was the data collected?
    • What devices were used and what settings were made?
    • Further details depending on the type of research data (for instance, precise details on materials/samples used or on the approach and instruction of test subjects)
  • Information on the further processing of the data, for instance:
    • How was the data validated in terms of content and technology?
    • How was the data cleansed?
  • Information on the structure of the dataset at hand
    • How was the data selected for the described dataset? Which of the originally collected data is not included and why?
    • How is the dataset structured (different types of data, folders, files)?
    • What do labels, codes, variables, and abbreviations mean?
    • What are the differences between different file versions?
F
FAIR Principles

In 2016, an initiative of researchers, librarians, archivists, publishers and research funders developed four basic principles for managing research data. These are called the FAIR Principles and include four objectives:

  • Findable – your research data is findable and citable.
  • Accessible – your research data is accessible.
  • Interoperable – your research data is technically interoperable.
  • Reusable – your data is understandable and can be reused.

DepositOnce enables the publication of research data according to the FAIR Principles.

File size

File size in DepositOnce is not limited. However, you should keep two points in mind:

  1. Each academic chair or research group at TU Berlin has a free data volume of 100 GB in DepositOnce. Additional storage space may be necessary when publishing research data and may be purchased from Campus Management (ZECM) by the head of the chair or research group (see Storage space).
  2. For technical reasons, you can only upload files of up to 4 GB on your own. If you wish to upload larger files, please contact the DepositOnce Team.
Findability

The results published in DepositOnce are searchable worldwide via search engines and other reference systems (such as BASE, DataCite, the German National Library, the library catalogue of TU Berlin, Google Scholar, Google Dataset Search). This is possible because DepositOnce offers standardized APIs for exchanging data between different systems. For example, via the OAI-PMH interface, other systems are able to automatically select and process the metadata of all items available in DepositOnce.

See also Interface.

Free data volume

See Storage space.

G
Good academic practice

In a 2017 statute, TU Berlin introduced its Principles to Safeguard Good Academic Practice and formulated fair procedures to be applied in the event of suspected violations. The principles are based on the corresponding Guidelines of the German Research Foundation (DFG).

Guest account

Those who no longer have a TU Berlin account can apply for a guest account for DepositOnce. If needed, please contact the DepositOnce Team, or, in cases involving dissertations, please contact the University Library Dissertation Service directly.

H
Habilitation theses

For detailed information on publishing habilitation theses in DepositOnce, see https://www.tu.berlin/go6743/.

I
Institutional repository

Institutional repositories are operated by research institutions for their members. The latter can archive and publish their research results there. Unlike disciplinary repositories, institutional repositories generally are not discipline-oriented. DepositOnce is an institutional repository.

Interface

As a registered OAI data provider, DepositOnce meets the requirements of the Open Archives Initiative Protocol for Metadata Harvesting(OAI-PMH) for collecting and processing metadata and uses the OAI-PMH interface to make the metadata freely available on the Internet in various formats. This enables automated delivery of the metadata, for example to the German National Library (for digital long-term archiving of publications) and indexing in (academic) search engines and catalogs (such as BASE, DataCite Metadata Store, OpenAIRE).

Item

In DepositOnce, a published submission is called an item.

K
Keywords

When publishing your research results, you must include keywords in your publication or dataset. These keywords are freely chosen terms that should briefly and concisely describe what your publication or dataset is about. Keywords can be indexed for searching purposes and in this way they serve to improve the findability of research results. Please enter approximately five keywords, each in both German and English; they should preferably be in the singular and consist of one or two – but not more than three – words per keyword.

L
Licenses

Generally, your material is subject to German copyright law. This means that others can only use your work within the scope of certain legal exceptions (e.g. right to quote). Please choose "In Copyright" if you don't want to grant others further rights of use to use your material.

In Copyright: Others cannot reproduce, distribute or modify your work without your permission.

If you want to grant others further rights (that go beyond German Copyright Law), you can assign an open license to your material. A free license allows others - under certain conditions - to use, reproduce, distribute and, in some cases, adapt your publication.

Please choose one of the seven Creative Commons licenses listed below. These licenses are standardized, widespread internationally and suitable for almost any type of text publication and research data. The only exception is software: For software, please use one of the free software licenses.

Please note:

  • If you have already granted rights to your work to a third party, it may no longer be possible to assign an open license to your work.
  • Additional conditions are not allowed with standardized licenses. That means you cannot choose one of the licenses and then give additional permissions or restrictions.
  • If you choose an open license, include the license information directly in your work if possible (cf. Instructions by Creative Commons).
Creative Commons licenses

Creative Commons licenses (often referred to as CC licenses) provide an easy way to grant the public rights of use. CC licenses are based on copyright regulations, but allow for a more extensive use of works than generally envisaged in copyright law.

See Creative Commons license.

Software license

For own software, it's recommended to choose a suitable software license.

See Software license.

Login

DepositOnce can be used by all members of TU Berlin. They can register using their TU Berlin email address.

Former members of TU Berlin who no longer have a TU Berlin account can contact the DepositOnce Team to arrange for a guest account. If you want to publish your dissertation, please contact the University Library Dissertation Service directly.

In the case of collaborative projects, members of partner institutions can also use DepositOnce to publish their research data, provided that TU Berlin is the project lead. For publications, however, this is not possible.

Long-term archiving

The digital preservation of publications is ensured through the long-term archiving system of the German National Library. For research data, the DepositOnce operator aims to preserve the research data stored in DepositOnce by cooperating with a suitable facility specialized in long-term archiving. Archiving is carried out in accordance with the German Research Foundation’s guidelines that require the archiving of research data for at least ten years. All creators are required to deliver their content in a format suitable for long-term archiving

M
Metadata

Metadata is data used to describe the content in DepositOnce in a structured and machine-readable way, with the purpose of making it easier to find (e.g. via search engines). During the submission process, authors assign some of the metadata (e.g. keywords, abstract) themselves.

The metadata of the digital objects stored in DepositOnce is freely available on the Internet; they are distributed under CC0 license. They may be retrieved, stored and made available – if necessary, in supplemented or reduced form – to third parties via the available open interfaces.

N
Naming of files and folders

Only use letters, numbers, underscores (_), and hyphens (-) for naming the files you publish at DepositOnce. Please do not use any of the following characters:

  • spaces
  • special characters: \ / ? : * " > < | : # % " { } | ^ \[ ] \` ~
  • non-ASCII characters: ¢ ™ ® etc.
  • extended Latin alphabet: ä ö ü ß etc.
  • diacritical marks: à é ô etc.

The file name extension should be consistent with the actual file format. Avoid generic file names such as “article.pdf”, “dissertation.pdf”, or “measurementdata.csv”.

O
Open Access (OA)

Open access aims to make research information freely and publicly available on the Internet, that is, without any financial, legal or technical barriers. Via open access, scholarly information can be disseminated, used and processed to the maximum extent. Examples of reuse include use in teaching, dissemination via social media channels, or the application of text and data mining methods. The term “open access” refers to publicly funded academic publications, research data, and digital cultural heritage.

Open access can be ensured either by publishing open access directly with the publisher or by open-access self-archiving via a repository (in addition to the publisher’s version).

DepositOnce is committed to the concept of open access and is a tool for TU Berlin to achieve the goals of open access as defined in TU Berlin’s Open Access Policy, TU Berlin’s Research Data Policy, the international Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities, and the Open Access Strategy for Berlin:

The metadata of the digital objects published in DepositOnce is published under a CC0 license and can be freely reused.

Open Access Policy

In December 2017, the Academic Senate unanimously adopted the Open Access Policy, which applies to all members of TU Berlin. The Open Access policy recognizes the importance of open access to academic content, provides recommendations for researchers, and outlines the various action areas for implementation.

See also Research Data Policy.

P
PDF/A

PDF/A is a file format for long-term archiving of digital objects, standardized by the International Organization for Standardization (ISO) as a subset of the Portable Document Format (PDF).

PDF/A Conversion

For the publication of PDF files in DepositOnce, the files must be submitted in the PDF/A format to ensure long-term digital archiving. PDF/A Conversion is a tool available for free to all TU Berlin members which can be used to check PDF files for PDF/A conformity and, if necessary, convert them to PDF/A format.

Persistent Identifier (PID)

A persistent identifier is a permanent identifier for digital objects. It consists of digits or alphanumeric characters. If the location of a digital object associated with a persistent identifier changes, the identifier remains the same – only the URL location needs to be changed or added to the identifier database. This ensures that a resource can still be accessed even when its web address has changed. Examples of persistent identifiers are DOI, URN or Handle. Digital objects in DepositOnce are automatically assigned a DOI.

Policy

The Policy for DepositOnce describes the service in detail. It contains, among other information, details on the accepted publication types, the user groups addressed and the rights and obligations of the University Library as operator as well as of the creators who use the service for publishing.

See also Research Data Policy & Open Access Policy of TU Berlin.

Publication

At the beginning of the submission process in DepositOnce, you need to decide what you want to publish – a publication or research data. In DepositOnce, the term “publication” covers all forms of text publications (see also Types). “Research data”, by contrast, refers to any form of data that underlies a text publication (see also Research Data).

R
README

See Documentation.

Regensburger Verbundklassifikation (RVK)

The Regensburger Verbundklassifikation (RVK) is a system for the classification of library holdings. It was developed at the University of Regensburg around 1964 and has become well established at German academic libraries. The RVK consists of 34 main groups, which are identified by capital letters. Subgroups are identified by adding another capital letter. The fine structure is made up of a numerical sequence of three to six digits. For example, “WF 9720” stands for the subject area “bioprocess engineering.” For dissertations, please provide an RVK code in DepositOnce.

Relations

If your publication has any relations to other publications (e.g. to research data in DepositOnce), please select the relationship type and enter the DOI or URN.

  • Is supplemented by: Creates a link to a supplementary publication (e.g. corresponding research data)
  • Is supplement to: Creates a link to a supplemented publication (e.g. when you publish the research data corresponding to your doctoral thesis)
  • References: Creates a link to a referenced item (e.g. the new publication cites the linked publication)
  • Is referenced by: Creates a link to a referencing item (e.g. the new publication is cited by the linked publication)
  • Is part of: Creates a link to a published work which includes this publication (e.g. in case of an article which in fulltext is included in a thesis)
  • Has part: Creates a link to a published work, which is included in the new publication (e.g. in case of a thesis which includes several articles, book chapters or similar)
  • Is version of: Creates a link to the main version of the work (e.g. when you upload a preprint or a translation)
  • Has version: Creates a link to another version of the work (e.g. to a preprint or a translation)
Repository

In a repository, files (such as publications or research data) can be stored for the long term and published if applicable.

Research Data

Research data is data that emerges during a research process, including all information that is needed to understand and reproduce research results. Research data can take the form of images, audio recordings, tables, texts, or databases, among others. DepositOnce offers you the possibility of publishing your research data.

At the beginning of the submission process in DepositOnce, you have to decide what you want to publish: a publication or research data. In DepositOnce, the term “publication” covers all forms of text publications (see also Types). “Research data”, by contrast, refers to any form of data that underlies a text publication. In DepositOnce, research data means consolidated data, that is, analyses and/or data required for the verification and reproduction of research findings such as consolidated raw data, scripts, calculations, etc. Research data generated in day-to-day operations is not stored in DepositOnce.

Research Data Policy

In 2019, TU Berlin has adopted a Research Data Policy that applies to all researchers working at TU Berlin. The Research Data Policy recognizes the scientific value of research data and recommends that research data should be stored in a correct, complete, unadulterated and reliable manner. In accordance with the FAIR Principles (see FAIR Principles), research data should also be findable, accessible, interoperable, and, where possible, reusable. Practical guidelines for the implementation have been added to the policy to give you more specific guidance on how to meet the policy requirements. There you will find everything you need to know about handling research data before, during, and after your research project as well as information on the support TU Berlin offers you in the individual phases.

See also Open Access Policy

S
Self-archiving

(Open access) Self-archiving means sharing a free copy in addition to the (closed access) publisher’s version. Self-archiving in a repository takes place either simultaneously or delayed. Self-archiving can be based on various legal grounds: terms or conditions stipulated in the publishing agreement, the publishers’ general policies, special Open access rights resulting from license agreements, Section38 of the German Copyright Act (UrhG) and, in particular, the statutory right of authors’ own re-use (Section 38 (4) UrhG) may apply.

The University Library offers a Self-Archiving Service to provide hands-on support for researchers at TU Berlin.

Service Center Research Data Management (SZF)

The University Library (UB), Campus Management(ZECM) and the Research Department (Department V) work together within the Service Center Research Data Management (SZF) to support TU Berlin’s researchers in managing their research data.

The Service Center Research Data Management provides the following services:

  • the DepositOnce repository for archiving and publishing research findings;
  • the web tool TUB-DMP for creating data management plans;
  • the SZF website which serves as a central source of information on research data management;
  • a wide range of training and consulting services.
Software license

When choosing a free software license, you should first decide whether and to what extent you want to allow others to commercialize derivations based on your software (options 1 to 4).

Secondly, you should orientate yourself on the other conditions that the licenses prescribe for further use.

1. The following licenses are "permissive licenses", i.e. they allow the direct integration of your software in proprietary code.

  • MIT License
    • The original copyright and attribution marks must be retained.
    • The full text of the license must be included in the modified software.
  • BSD License (BSD-3-Clause)
    • The original copyright and attribution marks must be retained.
    • The full text of the license must be included in the modified software.
    • Neither the name of the organization nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.
  • Apache License 2.0
    • The license grants others the rights to practice patent claims of the software owner and of the contributors to the code, in so far these rights are necessary to make full use of the software.
    • The original copyright and attribution marks must be retained.
    • The full text of the license must be included in the modified software.
    • The source code must be publicly available.
    • Source code modifications must be documented.

2. The following license forbids any integration of your software in proprietary code , as any derivation (code changes) based on your software must also be placed under the GPL license and thus remains free software. This also applies if the source code of another software is combined with your software and the result is passed on.

  • GNU General Public License 3.0 (GNU GPLv3)
    • The original copyright and attribution marks must be retained.
    • The full text of the license must be included in the modified software.
    • The source code must be publicly available.
    • Source code modifications must be documented.

3. The following license was produced for the special case of software libraries. Whereas - like in GPLv3 - the distribution of derivatives (code changes) based on your software must be done under the same (or a similar) free license, works made by using your software by means of static or dynamic linking can be distributed under any license.

  • GNU Lesser General Public License (GNU LGPLv3)
    • The original copyright and attribution marks must be retained.
    • The full text of the license must be included in the modified software.
    • The source code must be publicly available.
    • Source code modifications must be documented.

4. The following license also requires that derivations of your software are redistributed under the same (or a similar) free license, but users can combine your software with proprietary code, as long as your code is kept in separate files. This ensures that the application interfaces remain open, but that individual extensions can be proprietary.

  • Mozilla Public License 2.0 (MPL)
    • The original copyright and attribution marks must be retained.
    • The full text of the license must be included in the modified software.
    • The source code must be publicly available.
    • Source code modifications must be documented.

Statistics

At the moment, unfortunately, we are unable to provide you with reliable usage statistics (views and/or downloads) for your digital objects published in DepositOnce.

Storage space

Each TU Berlin academic chair has access to 100 GB of free storage space on DepositOnce. Additional storage space may be required in connection with the publication of research data. According to the ZECM’s conditions for storage expansion, the respective head of chair can expand the storage space: a one-off payment of €3,500 for 1 TB including data backup for 10 years. In many cases, reimbursement of costs for storage space can also be requested from the funding organization when submitting a research proposal. The Research Department staff will be happy to advise you in this regard.

Submission

Submission refers to the process of uploading content to DepositOnce and entering the associated metadata. A submission is completed once the content proposed for publication by the authors has been fully edited and approved for publication by the DepositOnce team.

With easy, step-by-step instructions, DepositOnce guides you through the submission process:

  • login
  • selection of “Publication” or “Research data”
  • uploading the file(s)
  • entering metadata (title, author, abstract, etc.) in the fields provided
  • confirmation of the data protection provisions and the Deposit license (= publishing agreement)

You can interrupt the submission process at any time, save the data you have already entered, and resume editing at a later point in time. Once you have started a submission, it is automatically assigned a DOI (Digital Object Identifier). After confirming the deposit license and finalizing the submission with “Deposit”, your submission is stored in a cache where you will no longer be able to edit it. A message is automatically sent to the DepositOnce Team who will then take the next steps:

  • formal verification of metadata and file(s)
  • publication

You will be informed by email as soon as your item has been published.

Support

If you need assistance with the use of DepositOnce, please contact the DepositOnce Team.
