Creating new nodes in KNIME

KNIME Analytics Platform
#1

I have seen documentation how to create new nodes for KNIME using Java coding.

Is it also possible to create a new node by grouping a workflow of standard nodes (e.g. some join, then filter and calculation and clustering) into a new composite node? This new composite node would then be published and available in the Node Repository for re-use.

Is something like this possible in KNIME? I guess this is done by so called Meta Nodes in KNIME? Can I also parameterize a Meta Node (not just in and out)?

Hi Holger,

yes this is possible. 

You need to collapse the nodes into a wrapped meta node. If you have quickforms inside the wrapped meta node you can configure those by configuring the wrapped meta node from outside.

 

You can see an example how this can be done here: https://www.knime.org/nodeguide/enterprise/webportal/example-for-a-data-mining-webportal
