+Item Metadata
+-------------
+Item stacks can store metadata too. See `ItemStackMetaRef`.
+
+Item metadata only contains a key-value store.
+
+Example stuff:
+
+ local meta = stack:get_meta()
+ meta:set_string("key", "value")
+ print(dump(meta:to_table()))
+
Formspec

Formspec defines a menu. Currently not much else than inventories are
Class reference
---------------
-### `NodeMetaRef`
-Node metadata: reference extra data and functionality stored in a node.
-Can be gotten via `minetest.get_meta(pos)`.
+### `MetaDataRef`
+See `NodeMetaRef` and `ItemStackMetaRef`.
#### Methods
* `set_string(name, value)`
* `get_int(name)`
* `set_float(name, value)`
* `get_float(name)`
-* `get_inventory()`: returns `InvRef`
-* `to_table()`: returns `nil` or `{fields = {...}, inventory = {list1 = {}, ...}}`
+* `to_table()`: returns `nil` or a table with keys:
+ * `fields`: key-value storage
+ * `inventory`: `{list1 = {}, ...}}` (NodeMetaRef only)
* `from_table(nil or {})`
* Any non-table value will clear the metadata
- * See "Node Metadata"
+ * See "Node Metadata" for an example
* returns `true` on success
+### `NodeMetaRef`
+Node metadata: reference extra data and functionality stored in a node.
+Can be gotten via `minetest.get_meta(pos)`.
+
+#### Methods
+* All methods in MetaDataRef
+* `get_inventory()`: returns `InvRef`
+
+### `ItemStackMetaRef`
+ItemStack metadata: reference extra data and functionality stored in a stack.
+Can be gotten via `item:get_meta()`.
+
+#### Methods
+* All methods in MetaDataRef
+
### `NodeTimerRef`
Node Timers: a high resolution persistent per-node timer.
Can be gotten via `minetest.get_node_timer(pos)`.
