  "doc": "Row identifier that Esri ArcGIS adds to every geodatabase table and feature class. The default field name is OBJECTID, or OBJECTID_1 when a column of that name already exists, and ArcGIS displays it as OID or ObjectID, and as FID in shapefiles and web feature layers. ArcGIS maintains the values. Each is a non-null integer that is unique only within its table, so the same number names different rows in different layers; Global IDs serve to identify rows across geodatabases. The field is a 32-bit integer by default, up to 2,147,483,647, and ArcGIS Pro can migrate it to a 64-bit object ID limited to 9,007,199,254,740,991. Datasets exported from ArcGIS keep it as an objectid or OBJECTID column, for example on Opendatasoft portals next to geo_point_2d and geo_shape, where it is sometimes stored as a decimal number such as 89.0. It is not the MongoDB ObjectId (mongodbid).",
