Extracting metadata from raster (tif) file using python in Knime

[mwiegand]

Hi @Leedsbash7,

I have recently tried finding a way to extract the XMP Meta data from images too and, whilst not Phyton, found a way to extract the information too using a simple RegEx

(?<XMP Meta Data><x:xmpmeta((?!</x:xmpmeta>).)+</x:xmpmeta>)

You basically:

1. Create a list of Paths to each image
2. Convert it to binary and remove all line breaks
3. Extract XMP and convert to XML

PS: I created a sample workflow for you- Whilst not using a tif, this still might be applicable.

Please note that the Python-Approach is still WIP because of:

Sorting causes "Error sorting table: Failed copying file stores to local handler"

Hi @carstenhaubold, circling back to this issue as it appeared again but in a different context using a Phyton Script node while trying to extract the meta data form an image. Not even saving is possible: [image] I had to reset the failing node to save the workflow. Upon trying to replicate the save issue as well as the error thrown in the Python node, they were not triggered again but instead this one: KeyError: 'Sample Images' Traceback (most recent call last): File "<string>", line 2…

Best
