Can I create a workflow via a programme?

[mlauber71]

in general KNIME nodes are XML files and the connections between them might also be interpreted as XML files and meta nodes.

You might aim for something like a technology demonstration where you create a simple workflow from a collection of nodes and create connections between them. Then you would discuss what are the challenges and present that as a:

• discussion what would be necessary to create such a meta creator
• create a small demo that would show how it would be done

That might be suitable for a masters degree. And also it might be interesting to see if you could create such a system with KNIME itself -)

As further inspiration I created a meta search using the XML files of KNIME:

Search a Node in a Knime Workflow by Id (Goto & focus a Node by ID)

A colleague of mine came up with maybe a similar question and we developed some super dirty approach that might give you an idea where to look. Since all things KNIME are stored in XML files we thought we might as well import them and search for a specific term. I constructed this scenario. I have my XML search meta workflow and a workflow in a subfolder (you might use any folder you like). I want to know where someone used the term “cryptic_xy_name” somewhere in the folder/workflow.

Use KNIME to search KNIME's workflow.knime and extract content – mlauber71

The other example would be a backup strategy that would use an outside tool to handle KNIME workflows:

Copy/Move Files Node

@zedleb I created and example where the KNIME workflow (or workflow group) is being zipped into a file with a current timestamp. And can later be restored to a (separate) folder.
