Metadata
In 3D, Metadata is custom user-defined attributes attached to 3d object, file or material.
Metadata editor shows list of metadata assigned to selected item and has functionalitry to edit it.
Following actions are possible:
Add button
- create new metadata record. If metadat group is selected, item will be
created in this group.

- Type of item may be:
| Boolean | Boolean data type is a data type that has one of two possible values Yes and No. |
| Integer | The value of an item is signed mathematical integer. Stored intenally as 32 bit signed integer. Range -2,147,483,648 to 2,147,483,647 |
| Floating point | Values are numbers that have fractional parts (usually expressed with a decimal point). Stored as double-precision, 64-bit floating-point data type. It accommodates 15 to 16 digits, with a range of approximately 5.0 × 10−345 to 1.7 × 10308. |
| String | Text data type with any characters and practically unlimited length. |
Metadata is imported from many 3d file formats, for instance JTOpen, FBX, SketchUP, IFC, STEP. Export is possible to U3D, WebGL formats and more. In WebGL metadata accessed by JS code. Check meta field of iv.node object.
