**summary box** = summaries can be added in the language to the summary box; also appears to be connected to Language select under the image.
**summary box name** = language name appears correctly in the summary box description field;
The **Saami languages:**
|l**code**| **langname** | **autonym** | **caption box** | **summary box** | **summary box name** | ** note**
