1. How can I submit a data to ScienceDB ?

As a non-profit, public data repository, ScienceDB hosts a dedicated data management team who will conduct a formal review of all submission for publishing. The data publishing process consists of the following steps:

1) User registration and login

2) Metadata and data submission

3) Data review: at this stage, your datas can only be accessed and downloaded by our data managers and designated reviewers. The data curation team reviews each submission and sends you conclusion via email within 5 working days.

4) Online data publishing: publish your data openly for public access under a specific data reusing license.

2. What are the restrictions on the format, subject area and size of a data submission ?

At ScienceDB, we welcome submissions of data in any format, subject, or size.

However, we do have preferred data formats in consideration of optimal data reusability. For details, please refer to Notes on recommended data formats

Additionally, we provide different ways to upload different sized datas, browsers or FTP clients. Please refer to Data publishing procedure for details.

3. How much do you charge for data publishing ?

To encourage participation in open data sharing, we do not charge individual users at present. All fees incurred throughout the publishing process will be waived. However, we reserve the rights to charge users for data storage, review and publishing, and do not guarantee life-long free services.

For collaborative services of academic journals, please Contact us.

4. Do you provide DOI services for all accepted data ?

We provide free DOI registration for all data accepted to publish on ScienceDB.

A unique DOI will be assigned to each data submission, with its prefix being “10.11922/sciencedb.”(e.g., “10.11922/sciencedb.00053”).

However, a DOI will only be activated when we have it registered, after the data is formally accepted for publishing on ScienceDB. An unregistered DOI is inactive and cannot be used to locate data resources.

It usually takes one or two working days for us to register a DOI after a data is formally published. A DOI link (i.e.,http://www.doi.org/[DOI]) will be provided and activated for locating and accessing the data. A DOI link (e.g.,http://www.doi.org/10.11922/sciencedb.00053) corresponds to a data (i.e.,“10.11922/sciencedb.00053”) on ScienceDB.

Additionally, each data submission will be assigned a PID and a CSTR, with their prefix being “21.86116.6/sciencedb.” and “31253.11.sciencedb.”,respectively. Both are unique identifiers of a data that works approximately the same as a DOI.

* CSTR – Science and Technology resource identification, GB/T 32843-2016.

5. How do you protect data submissions whose papers have not yet accepted ?

At ScienceDB, we support data protection when a data is considered as not ready for open sharing.

Depositors are able to set a limitation period during the data submission, which can be one, three, six, or twelve months contingent on specific scenarios (Please note we do not support a limitation period longer than 12 months at present). It is counted as starting from the time when the metadata is published online. Within this period, visitors have access to metadata only but not to data files.

Besides, a private access link will be generated once a data is submitted (http://www.scidb.cn/en/s/[random codes]), which depositors can share with journal editors or peer reviewers when their data files are not yet published or under the embargoed period. This link would allow anonymous metadata access and data file download. Depositors should keep it properly and only share it with another party when appropriate.

6. What license agreements does ScienceDB support ?

At ScienceDB, we currently support two data license agreements, namely, CC0 and CC-BY 4.0.

1) CC0 (no copyright reserved)

Content submitters shall state that they are the producer and owner of the content submitted, or have sufficient rights to publicize the content under CC0.

Under CC0, data depositors and all stakeholders relinquish all copyright they hold and dedicate their work to the public domain without being restricted by copyright law.

Anyone can copy, modify, disseminate, and execute all or part of the work under CC0 without being licensed to do so, in any way and for any purpose, even commercially.

CC0 is formulated by Creative commons. For details, please read CC0 1.0 Universal (CC0 1.0) Public domain dedication at: https://creativecommons.org/publicdomain/zero/1.0/.

2) CC BY 4.0

Content submitters shall state that they are the producer and owner of the content submitted or have sufficient rights to publicize the content under CC-BY 4.0.

Under CC-BY 4.0, anyone can copy and distribute the data in any medium or format, or adapt, transform and build upon the data for any purpose, even commercially.

However, anyone who uses a data in the way as mentioned above shall give credit to its original authors, provide a link to the license, and note changes if any. While we accept all reasonable ways for doing so, users should not take advantage of it to imply the data licensors’ endorsement of the users or their research findings.

CC-BY 4.0 is formulated by Creative commons. For details, please refer to the CC-BY 4.0 International at: https://creativecommons.org/licenses/by/4.0/legalcode.

7. How can I update an already published data ?

At ScienceDB, all depositors are allowed to update their published data. To do so, depositors need to make an online request on “My Datasets” page. An updated version will be published once it is approved by our data managers.

Please note that no new DOI will be assigned for an updated data. All historical versions of the data will be retained and are open for public assess.

8. How can I cite a data published on ScienceDB ?

Users can find an automatically generated, adaptable citation format on the webpage of the data they want to cite. We strongly encourage users to cite all data that contribute to their research work. Here is our recommended citation format as per the webpage:

Author(s). Title. Data Version. Science Data Bank. http://www.doi.org/Data DOI. (date published).
Author(s). Title. Data Version. Science Data Bank. http://datapid.cn/Dataset CSTR No. (date published).

An example can be:

Wang Juanle, Chen Eryang, Zhu Junxiang, Zhou Yujie. Suspended solids concentration in the Poyang Lake 2000-2013 inversion of data collection. V1. Science Data Bank. http://www.dx.doi.org/10.11922/sciencedb.1. (2015-07-15).

Regarding with the data supporting an associated peer-reviewed publication, you’re not mandated to cite the article simultaneously. For credit depositors’ research, however, we encourage you to make a reasonable citation to digital publications that are helpful to your research.

9. How long can my data be stored on ScienceDB ?

Established on FAIR principles, ScienceDB provides permanent access to all data accepted for publishing on this site, unless the data violates relevant rules or regulations.

10.Can I retract a published data ?

Once published online, data cannot be retracted in principle. Depositors who want to make modifications have the option to update their data version. At ScienceDB, we allow depositors to upload new versions of their previously published data (please refer to Data updates for more information), as a way to support data updates. After a new version is published, the old version will still be open for public access and download.

However, if your data contains substantial deficiencies such as major data errors which may seriously impact the research of your data users, please do not hesitate to contact us and follow our steps for data retraction:

Depositors shall fill out the two forms (Request for Data retraction and Statement on Data retraction) and send to: sciencedb@cnic.cn.

Your request will soon be forwarded to our staff for review and evaluation. If we decide that your data should be retracted as per your request, data depositors will be asked to sign the Statement and send a scanned copy to our email. A retraction will be proceeded once we receive the copy.

A retraction, however, does not eliminate your option to submit and publish an updated version of the data retracted. For submitting a new version, please click “update” in “My Datasets” page.

Notes: the updated version shares the same DOI/PID/CSTR with the original version. The access link of the original version remains valid even if the data has been retracted, in which case metadata are retained and the data files are substituted by a Statement on Data Retraction.
