KNIME Hub is the place where you can search for nodes, extensions, components, and workflows made available by the community.

You can use these as blueprints and building blocks in KNIME Analytics Platform, and build workflows to solve your data science use cases.

KNIME Hub can also be used to upload and organize workflows in a central place, and to collaborate with other users on your projects.

Via KNIME Hub you can:

  • Find workflows, components uploaded by KNIME Community

  • Upload and organize your workflows and components in projects

  • Create and manage projects

  • Collaborate with other users on your projects

KNIME Hub as a repository

Not only KNIME Community Hub serves as a repository for nodes, components, workflows, and extensions, ready to use in KNIME Analytics Platform via an easy drag & drop, but also you can use KNIME Community Hub to share your workflows with the KNIME Community or to store and organize your material in a private space.

Create a user account

First, if you do not have one already, create a user account. Go to KNIME Hub, click Sign in on the top right corner of the page, and then select Create account. Fill in the required information and click Create new account. Now you can sign in with your account. Click the user icon on the top right corner of KNIME Hub and select Profile from the menu to have access to your profile page. Here you can have an overview of the workflows and components you published, the extensions you published in case you have developed any of those, and the likes received. Also, you will have a list of the items you liked on KNIME Hub.

KNIME Hub spaces

From your profile page or by clicking your profile icon and selecting Spaces you will have access to the KNIME Hub spaces that are linked to your user account. A space is a KNIME Hub repository where you can store and share your workflows and components. When you register and sign in KNIME Hub two spaces will be automatically created. These are a private space and a public space, which have different access permissions. You can manage your spaces by changing their name or adding a description to them. You can upload your items from KNIME Analytics Platform to the spaces you have access to. Moreover, you can create new spaces, both private and public. Finally, you can add contributors to your public spaces. All these functionalities will be explained in the following paragraphs.

Access permissions of spaces

You are the owner of your spaces. Each space is linked and assigned to a specific user.

Spaces can be private or public:

  1. A private space is only accessible and manageable by your user account. Here you can store various types of items like workflows, components, or data.

  2. A public space, instead, is visible to the entire KNIME Community where you can share your workflows and components. Everyone will then be able to download them, drag & drop them to their KNIME Analytics Platform and use it, as well as like your spaces or items, or copy a link to your space and share it with others.

It is also possible to switch a space from private to public and vice versa. To do so go to the private space you want to make public, click the three dots on the top right part of the page and under Visibility select Make public (or vice versa select Make private).

When you are added as a contributor to a space you will be able to see the space under Spaces in your profile page and also listed in your KNIME Hub mount point from KNIME Analytics Platform.

Contributors have edit rights for the space they are added to. They can add and edit workflows or components on the space. They do not have the same rights that the owner of the space has. Only the owner of a space can change the space name or change the space visibility to private.

Please notice that since contributors can only be added to public spaces, the contributors will not have access to the space anymore in case the space visibility is changed from public to private.
