On top of the search results list, you can filter the results to list only nodes, components, workflows, extensions, or collections by clicking the respective tab, shown in Figure 2.

Click on a search result to access the relative page.

When searching for workflows and components, the items that have been versioned will show up higher in rank than draft-only items. This ensures you to be able to easier find versioned workflows and components when searching on KNIME Hub.

You can drag & drop nodes, components, extensions, and workflows from KNIME Hub to import them into KNIME Analytics Platform and use them right away to build your own workflow, install KNIME Extensions, and execute uploaded workflow into your local installation.

First, if you do not have one already, create a KNIME user account. It will grant you access not only to KNIME Hub but also to other KNIME products, such as the KNIME Community Forum.

Go to KNIME Hub, and in the top right corner of the page, click Sign in. Then select Create account. Fill in the required information and click Create account.

After confirming the link sent to your email address, you can sign in with your account. Click the user icon in 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.

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 to 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 names 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.

You can connect to your KNIME Hub account on KNIME Analytics Platform.

To do so, go to the Home page of KNIME Analytics Platform and sign in to KNIME Community Hub.

You will be redirected to the sign-in page if you are not connected in the current session already.

Once you are signed in, you will see all your spaces.

Click on a space to access the items within the space. You can perform different types of operations on them:

Once you are connected to your KNIME Hub account from KNIME Analytics Platform, you can upload the desired items to your KNIME Hub spaces.

You can upload workflows or components to any of your spaces by right-clicking the item from the space explorer in KNIME Analytics PLatform and selecting Upload from the context menu. A window will open where you will be able to select the location where you want to upload your workflow or component.

When uploading items to a space on KNIME Hub, you will be able to keep track of their changes. Your workflow or component will be saved as a draft until a version is created.

When you create versions of the items, you can then go back to a specific saved version at any point in time in the future to download the item in that specific version.

Once a version of the item is created, new changes to the item will show up as draft.

You can move items that you have uploaded to KNIME Hub to a new location within the space that contains the item, or to a different space that you have access to. To do this, you need to be connected to the KNIME Hub mount point on KNIME Analytics Platform. If you want to move items within the same space, drag the item in the space explorer, for example, to a subfolder. To move items from one space to another, right-click the item and select Move to. In the Destination window that opens, select the space to which you want to move the item to.

You can also delete items that you uploaded to KNIME Hub. To do so, you can:

Go to any workflow, component, space, extension, or node on KNIME Hub and click the Copy link button on the top right, as shown in Figure 22. You will copy to your clipboard a URL short link to the item that you can share with others.

The short link is assigned uniquely to every item that is on KNIME Hub, regardless of its location. This means that even if the item is moved by its owner into a different space, the item will be reachable at the same short link.

The same rule is valid for the URL, which will be redirected to the new location automatically.

If you find an item on KNIME Hub that has been very useful for you or that you particularly like, you can leave a like by clicking the heart icon on the top right of the page. See how much the KNIME Community has been engaged in specific items by looking at the number of downloads and likes that a specific item has received, as shown in Figure 23.

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

You can add any other user of KNIME Community as a contributor to any of your public spaces.

To add a user as a contributor to a public space, go to the space and click the pencil tool close to your profile icon.

In the Manage space access panel that opens, you can add contributors by inserting their KNIME Hub username. Then click Add and Submit.

In the same panel, you can also manage the contributors. Click on the icon to remove a contributor from the space.

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 in 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.

To create a team, you need to subscribe to a Team plan. To do so, sign in with your KNIME Hub account and navigate to Pricing in the top right corner of the page, 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 your payment information. Then, you can 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 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 the 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.

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

You can create a new space by going to the team’s profile. To do so, click your profile icon in the top right corner of KNIME Hub and select your team. In the tile Create new space, click Private space to create a private space for your team, or Public space to create a public space. You can then change the name of the space, or add a description. You can change or add these also later by going to the relative space page and clicking the space name or Add description button to add a description for the space.

Furthermore, you can change the visibility of the space from private to public and vice versa, or delete the space. To do so, from the space page, click the icon, as shown in the image below.

You can also manage the access to a specific space. To do so, navigate to the space and click the icon.

In the Manage space access side panel that opens, you can add other team members. You can change the rights they have on the items in the space - e.g. you can grant them Edit rights or View rights for this space.

Click the icon to inspect the individual team members and their rights separately.

You can manage your team by going to the team’s profile. To do so, click your profile icon in the top right corner of KNIME Hub.

In the dropdown menu that opens, you will see your teams. Select the team you want to manage to go to the corresponding team’s profile page.

Here, you can click the Manage team button to open the Manage members side panel, as shown in the image below.

You will see here a list of the team members and their assigned roles.

From here, a team admin can change the roles of the team members. To do so, click the drop down arrow close to the name and select the roles you want to assign to each user.

Then click the Save changes button to apply your changes.

On the team’s profile page, you can also change the name of the team. To do so, double-click the name of the team under the team logo on the left side of the page.

Insert the new name, and click the button to confirm.

On the team’s profile page, hover over the team profile icon and click on Upload new to select an image from your local computer.

Here you can:

*Show the cost breakdown: Click Show cost breakdown to see the amount to be paid for your Team plan and the consumed credits for execution.

Execution allows you to run and schedule your team’s workflows directly on KNIME Hub.

To do this the first step is to configure the resources you need.

As the team admin, go to your team’s page and select Execution resources from the menu on the left. Here you can create an execution context, which contains all the necessary resources to run your workflows.

This is how your page will look like the first time you create an execution context.

When you click the button to create a new execution context a panel on the right will open.

Here you can configure the capacity of your execution context. Select the size of the execution context to decide how performant your workflows execution will be. You and your team members can execute as many workflows as you wish, even in parallel.

We offer three different execution context capacities:

You will be charged only when the execution context is running. The execution context will start and stop automatically on demand. This means that it will start automatically when the execution of a workflow starts. The execution context will then stop automatically once all the workflows executions are finished.

Each execution context is based on a specific version of the KNIME Analytics Platform provided by us. Find an updated list of the extensions available on the executor here.

You can inspect the status of an executed workflow, for example if the workflow execution did not succeed, or the execution is taking a long time. Click the icon for the desired job and select Inspect.

Here you can hover over info and error icons at the node’s traffic light, to visualize the message, check where the execution stopped or the status of specific nodes. You can also inspect the data at any node’s output port.

You can also navigate inside components and metanodes and inspect the nodes.
