Allow any structure in custom field in metadata

[dmirecki]

I am working on a model for which I need to define what kind of data the model is able to process. I define some high level structure that describes the data and now I am trying to put it in the seldon's metadata. In this way, client can easily check what kind of data my model supports.

I tried to use custom field in metadata endpoint, but, unfortunately, the field only supports str -> str mapping. As I mentioned, I have to pass more complicated structure (nested dictionary, lists). From that stems my feature request to allow any structure in custom field in metadata.

Hi @dmirecki,

The custom field is really meant to be tags or labels (so just str->str) but is named custom to avoid confusion with k8s labels or request tags.

What you can do is to specify type jsonData and then schema field should (as far as I remember) accept anything you define there, see https://docs.seldon.io/projects/seldon-core/en/latest/reference/apis/metadata.html#jsondata-input-output

Hi, thank you for response.

Your were right, schema in input and output accept any structure, so I can use that for my case.

Thank you!
