DataHub: Uploading Data

Uploading Data

There are several ways to upload the data, depending on the size of the files:

  1. Through the DataHub Interface where you can drag and drop files of up to 5GB (default limit). If you need to upload a single file that is bigger than 5GB, please contact us at <researchdata@hku.hk>.
  2. Using the FTP Uploader or the Figshare API, especially when working with large file/s or bulk upload.
  3. Using the Connect with GitHub, if you want to submit the code in your GitHub.

 

DataHub Interface

1. After you have signed in, click on the “My data” page and press the +Create a new item button from the top left of the page to start the uploading process.

Fill in the reference URL or DOI link if applicable, and then select the appropriate license you wish to obtain. The default license will be CC BY-NC if no other preferred type of license is chosen.
undefined

 

8. If you would like to link your dataset record with another external article or dataset which is related to your submitted dataset, you could input the title of the external material in “Resource title” and the respective DOI in “Resource DOI”.

You may refer to an example of a dataset record linked with external resources.

 

9. Click on “Save changes”.
undefined

 

10. At this stage, your data have been uploaded but not yet been publicly available. You may follow the steps stated in section Publishing an item under Publishing Data for making it permanently available.

 

Before publication, you are advised to review the below:

-   Restricted Access is available for applying to your dataset record before publication. Please read the Restricted Access section for details.

-   Reserve a DOI for your dataset. You may use the reserved DOI for citation before it is published.

 

FTP Uploader

FTP Uploader allows you to easily and securely upload files in your account directly from your computer by using a secure FTP connection. To use this method, you need to install an FTP client like Filezilla (but any FTP client will work).


When you have successfully downloaded and installed Filezilla on your device, please refer to the below step-by-step guidelines on how to establish FTP connections between Filezilla and DataHub, as well as how to upload files via Filezilla.

 

Step 1

Retrieve FTP Username and Password on DataHub

Go to DataHub and login with your HKU credentials. Click on “Applications” from the drop-down menu on the top right corner.

Mark down the “Username” for your account and press on “Generate Password” to retrieve the password for later use.

 

Step 2

Establish Connection Settings

Open Filezilla, Select File > Site Manager…

Follow the instructions step by step in the below image:

Item 3-4: Follow the below settings:

Host: ftps.figshare.com    Port: 21

Protocol: FTP - File Transfer Protocol

Logon Type: Ask for Password

User: The username you copied from DataHub in Step 1

 

Step 3

Start uploading your files

Please read the reminder notes (under the session “Before you begin”) at https://help.figshare.com/article/upload-large-datasets-and-bulk-upload-using-the-ftp-uploader-desktop-uploader-or-api

**Create ONE folder under the ‘data’ folder only. Please do not create any sub-folders under this newly created folder.

**You are recommended to break down your zip folders in around 5GB per each if possible.

Tips: You are recommended to upload a testing text file to test the uploading flow before you actually upload your data files. You can delete the testing file from your data record afterwards.

 

Step 4

Double check your uploading status and files uploaded

Return to DataHub, if you have successfully uploaded any files onto the folder directory in Filezilla, an item record with the same name of your created directory will appear automatically on your “My data” page on DataHub.

Whenever a folder has been successfully uploaded via the FTP uploader, it will appear under this item record.

**Note: The item record does not appear if you haven’t uploaded any files under the new folder directory on Filezilla.

 

Step 5

Amend the metadata of this item record

Enter the metadata as per the requirements, including title, author, descriptions, item type, category, etc., as per the upload via DataHub Interface guideline. Your item record will be ready to be submitted and published once the metadata are completed.

 

For Research Postgraduate student, return to Step 4 in the Submission Guide to complete the metadata requirements, and proceed to the remaining submission steps.

GitHub

To connect Figshare with your GitHub account, you can get set up in the Applications section, also located in the dropdown menu at the top right corner next to your name. Next, select Connect as shown below:

undefined

 

After sign in to your Github account where you will authorize Figshare, click off the Configure Github Integration overlay, go to My Data and click on the GitHub icon as the figure below.

undefined

 

Then, you can start importing GitHub from your list of public repositories:

undefined

 

If you configure the auto-sync setting to ON, figshare will automatically update for every release (for each of your imported repos) and this will only occur if your figshare item is public. Each new release would generate a new version of your figshare item.

 

For how to connect Figshare with your GitHub account, please click the following link for details:

https://knowledge.figshare.com/articles/item/how-to-connect-figshare-with-your-github-account

Figshare API

The Figshare API allows you to push data to Figshare, or pull data out. It also can create collections out of public content or build applications on top of the functionality.

Documentation on how to use Figshare's API can be found at https://docs.figshare.com/.

Uploading Data with Conditions

Restricted Access

There are occasions that you may wish to upload your data with access control conditions, especially for the sensitive data that conveys personal identifiers. The below will guide you through the steps required for setting up access restrictions to your files.

If your data contain sensitive, confidential or restricted data per the HKU Policy on Research Ethics, you are required to handle those data by means of either of the below two methods:

  1. Upload the data under restricted access

  2. Make and upload a version that anonymizes the data, for public access (with the approval of relevant IRBs or ethics committees)

Please refer to the "Restricted Access" section for a detailed step-by-step guide.

Linked Files

If your data is already retained in an external repository, you may wish to create an item record with the link directing others to where your data is stored.

Instead of browsing or dragging any files, click the “Link file” button at the top right of the page.
Note: This option is available only if you have not uploaded any files to the item.undefined

 

Copy and paste the link into the box.
undefined

 

If you would like to edit the link, you are required to remove it completely by clicking the cross symbol (remove link) and add a new one.
undefined

 

The link will be shown on top of the published metadata page as shown below. You can refer to an example of a linked file item.

undefined

Metadata Record Only

If your data are forbidden to be uploaded onto another repository owing to copyright issues, or the data are considered to be too sensitive to be uploaded (with valid justification), you may wish to create a metadata record only.
Without any file(s) being uploaded, tick the “Metadata record only” box at the top left of the page.
undefined

 

Fill in the reason(s) for creating a metadata record only. Provide the access information if data are preserved in an external repository.
undefined

 

Once the item is published, the metadata record page will be publicly available with no file to be shown. You can refer to an example of a metadata record.

undefined

Reserving a DOI

By publishing your research on DataHub, a DataCite DOI will be automatically allocated, which will enable your data to be cited using different citation methods.
However, if your data are not ready to be published yet, you may also reserve a DOI during the uploading process. It will only be active and citable when the item is published.

 

Select “Reserve Digital Object Identifier” at the bottom of the item details page.
undefined

 

A DOI will then be generated immediately.
