Adding multiple value via ION API to IDM Document in ION Workflow

Hi All,

iam trying to updating a document in IDM via ION API in ION Workflow. Im detail i want to update a multiple value attribute. My goal is to add a text to the multiple value collection.

Iam trying to use api "IDM/api/items/{pid}" this works but just deletes the hole collection and adds my new value. I fact i just want to add an value and do not want to replace the other ones.

I have also tried to retreive the old values via an api call, first. But the problem is, that i do not know how big the collection is and i am only be able to map one value to an output variable. It is not possible to retreive the hole collection of multiple values and bind it to an variable in IonWorkflow.

Regards.

Chris

I'm not aware of a REST method to append multi-value attributes. I think you'd probably have to retrieve and then append like you already tried. Can you expand upon the issues where you can't retrieve the existing attribute values? Since you are using a Workflow have you tried using a python script activity to build the the attribute payload?

I've run into this before, and agree with Andy - in order to make this work you'll need to first get all the existing values, then add your new one, then submit. I did something in a document flow using "merge" for this issue quite a while ago, however, I think this should now be doable with an ION API Flow where you pass in the new value (along with the target 'pid', etc ...) then first call the GET /items/{pid} then add your new value using JQ then call PUT /items/{pid}.

disclaimer: I have not yet tried this (but pretty sure it should do the trick! though you might have to first search for the doc if you don't know the pid)

Check for multi-value attributes the result of an existing document. you can find them in "colls". Example JSON for PowerShell:
