Starting From a Public Workflow

Many problems have been solved before, and a public workflow is the quickest way to a starting point. NodePit indexes the workflows that people publish, together with the nodes they use, so you can find one by topic and know what you need to install before you open it.

Search for workflows

Search with kind=workflow to get workflows only:

curl -s "https://nodepit.com/api/search?query=text%20mining&kind=workflow&limit=5" \
  | jq '.items[] | {name, url}'

Open the url of a hit in your browser to see the workflow and download it.

See which nodes it uses

The answer for a workflow lists the nodes it uses. Ask for it with the ID of the hit, encoded for use in a URL:

curl -s "https://nodepit.com/api/workflows/<nodePitId>" \
  | jq '{name, nodes, downloadUrl}'

With the IDs of the nodes, you can find the extensions you need, as in Finding the Extension for a Node. Install them before you open the workflow, and it opens without red markers.

With an AI assistant

Ask a connected assistant:

Is there a public KNIME workflow I can start from for text mining?

It searches for workflows, and can tell you which nodes the best match uses. See Connecting an AI Assistant if you have not connected one yet.
