How to use Array/Object fields in “Add a field” in Document Intelligence Studio? Are they supported in Azure Government?

Question

I want to use Array/Object field in “Add a field” in Document Intelligence Studio in Azure Government.

I could use Neural Model (not template) but all I could see is as below, Field, Selection mark, Signature and Table. I tried to use Table with selection mark but it has been working as field. I tried to reset my my project with Neural Model with API version 2024-11-30. but I couldn't access Array/Object field. are they supported in Azure Goverment?

Answer 1

Array/Object field types are not exposed as separate options in the Add a field menu in Document Intelligence Studio. In the Studio labeling UI for custom extraction models (template or neural), the available label types are:

• Field
• Selection mark
• Signature
• Table

This matches the documented capabilities for custom models, which focus on form fields, selection marks, tables, signatures, and region labeling, with no mention of Array/Object as distinct label types.

For Azure Government, Document Intelligence Studio is supported via the sovereign-cloud endpoint (Azure Fairfax) and supports v3.x+ APIs for custom model training and analysis, but the same Studio experience and label types apply. There is no additional Array/Object field type available in Azure Government beyond the standard Field/Selection mark/Signature/Table options.

To represent structured or repeated data, use:

• Table labels for repeated row/column structures.
• Field labels (optionally grouped by naming convention) for logical objects.

Array/Object semantics must be modeled in how fields and tables are named and consumed in application code, not via a separate Array/Object label type in Studio.
