How to update the item properties from metadata using the Python API?

JonathanBailey

Through the ArcGIS Portal UI, when I edit the metadata for a portal item, the item's properties are updated when I save the metadata record:

However, when I update the item's metadata from the Python API, the item's properties are not updated. I've used the following 2 methods to update the item's metadata:

item.metadata = esri_metadata_file_name

item.update (metadata=esri_metadata_file_name)

Is there a way to, using the Python API, to update the item's properties when the metadata is updated?

Hi Egge-Jan,
Thank you for posting your script file... very useful.

Question: what do you use as a resource to identify the name of the metadata item eg. 'snippet' or 'licenseInfo'.

For example, if I wanted to update: metadata > Resource > Citation > Titles & Dates > Revision Date - see screencap - what would be the keyword to use in the 'dictitem_properties' in the script.

cheers,
Greg

It seems to be working for most metadata XML files I try, but there are a few where only uploading through ArcGIS Online manually works. This is at version 1.7.1 of the python API.

I also use XML metadata file to maintain ArcGIS online metadata. Take a look at my GitHub repo. It works with version 1.5.2 (haven't tested with 1.6.0).

Can you please confirm if you are able to update (overwrite) the metadata successfully by providing the local metadata file in the user interface of ArcGIS Online?

If yes, then you can track the network request to extract the URL and the parameters and send an https request using requests python module.

You would also need token, so use REST API again to generate token.

Hi Munacghiso,

Partial success -- I was using v1.6.0, so I went back to v1.5.1, and I'm now able to get the Description of the item to update. Other attributes, such as Credits, are still not updating, however.

What version of the Python API are you using? Can you try the item.update with version 1.5.1 of the Python API? The newest version 1.6.0 did not work for me but 1.5.1 did.

OK - would not know how to accomplish that. Let's see what others have to say about it...

Hi Egge-Jan,

Thank you for your response.

However, I'm trying to go in the other direction. I have an XML metadata document that I'm applying to the item. I'm wishing to have the item properties updated without having to write additional code to parse the XML and explicitly set the properties on the item.

Jon.

Good morning Jonathan,

Please have a look at the example below. This script allows you to get your item and to update metadata items like the snippet, the description, the Terms of Use, the credits and one or more tags.

HTH,

Egge-Jan
