Introduction

KNIME Community Hub is a KNIME-managed Hub instance.

It is a central place to collect the common knowledge base among the KNIME Community and it has search functionalities as well as collaboration capabilities.

On KNIME Community Hub 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).

KNIME Community Hub is also the place where you can collaborate with the KNIME Community.

Once you have created your profile and uploaded your items in your public spaces you can share them with others, you can remain engaged in other people’s work by liking items or leaving a comment. Finally, you can also add other users from the KNIME Community as contributors to your public spaces. They will be able to access your space from their KNIME Hub profile and from their KNIME Hub mount point on KNIME Analytics Platform, download, and upload workflows or components. Add contributors to your spaces to collaborate on a project and keep all workflows always accessible in one place.

Recently, KNIME Hub Teams has been added to KNIME Community Hub. This feature allows you to create a team on KNIME Hub. A team is a group of users on KNIME Hub that work together on shared projects. You will be able to create Spaces that collect your team resources, such as components, workflows and data files, to which all the team members will have access.

All the items you liked will be shown on your user profile under Overview.

Teams

KNIME Community Hub Teams is a paid service offered on the KNIME Community Hub.

A team is a group of users on KNIME Hub that work together on shared projects. Specific Hub resources can be owned by a team (e.g., spaces and the contained workflows, files, or components) so that the team members will have access to these resources.

You can purchase a team and choose the size of the team, meaning the number of users that will be able to access the team resources, and the disk space that you need to save your team workflows, data, and components.

The team can own public or private spaces. For more details see the section Team owned spaces.

The items that are stored in a team’s public space will be accessible by everyone and be presented as search results when searching on KNIME Community Hub. However, only team members will have upload rights to the public spaces of the team.

Also, since only the team members have read access to the items that are stored in a team’s private space KNIME Community Hub users that are part of a team can collaborate privately on a project.

Create a team

To create a team you need to subscribe to a Team Plan. To do so sign in with your KNIME Hub account or go to KNIME Hub pricing page. Here you can proceed with the subscription to the Team Plan.

You will be asked to provide the details of the account and to choose your subscription plan. You can choose how much disk storage and how many users you would like to purchase. The basic plan consists of 30GB of disk storage and a total number of 3 users. Please note that the subscription will be automatically renewed every month if not canceled and that users and disk storage can be adjusted later. Your usage will be prorated for the next billing cycle. To change or cancel your subscription follow the instructions in the section Manage team subscription.

Once you have successfully purchased a team you can assign it a name and start adding members to your team. The number of members that can be added to the team is limited to the number of users that you purchased.

There are two types of roles a user can be assigned when part of a team:

The team creator is automatically assigned administrator role and can promote any of the team members to administrators. In order to do so please follow the instructions in the section Manage team members.

Team owned spaces

A team can own an unlimited number of both public and private spaces.

  • Team owned private spaces: Only the team members instead have read access to the items that are stored in a team’s private space. This will then allow KNIME Community Hub users that are part of a team to collaborate privately on a project.

You can create a new space by going to the team’s profile. To do so click your profile icon on the top right corner of KNIME Hub.
