-structure and file naming. There are two sector namings possible,

-sector/XXXXZZZZ and sector/XXX/ZZZ.
+
+This applies to a world format carrying the block serialization version 22
+which is used at least in version 0.4.dev-20120322.
+
+The block serialization version used is 22. It does not fully specify every
+aspect of this format; if compliance with this format is to be checked, it
+needs to be done by detecting if the files and data indeed follows it.
+
+Legacy stuff
+=============
+Data can, in theory, be contained in the flat file directory structure
+described below in Version 17, but it is not officially supported. Also you
+may stumble upon all kinds of oddities in not-so-recent formats.
+
+Files
+======
+Everything is contained in a directory, the name of which is freeform, but
+often serves as the name of the world.
+
+Currently the authentication and ban data is stored on a per-world basis. It
+can be copied over from an old world to a newly created world.

+Map File Format
+================
+
+Minetest maps consist of MapBlocks, chunks of 16x16x16 nodes.
+
+In addition to the bulk node data, MapBlocks stored on disk also contain
+other things.
+
+History
+--------
+We need a bit of history in here. Initially Minetest stored maps in a
+format called the "sectors" format. It was a directory/file structure like
+this:
+  sectors2/XXX/ZZZ/YYYY
+For example, the MapBlock at (0,1,-2) was this file:
+  sectors2/000/ffd/0001
+
+Eventually Minetest outgrow this directory structure, as filesystems were
+struggling under the amount of files and directories.
+
+Large servers seriously needed a new format, and thus the base of the
+current format was invented, suggested by celeron55 and implemented by
+JacobF.
+
+SQLite3 was slammed in, and blocks files were directly inserted as blobs
+in a single table, indexed by integer primary keys, oddly mangled from
+coordinates.
+
+Today we know that SQLite3 allows multiple primary keys (which would allow
+storing coordinates separately), but the format has been kept unchanged for
+that part. So, this is where it has come.
+</history>
+
+So here goes
+-------------
+map.sqlite is an sqlite3 database, containg a single table, called
+"blocks". It looks like this:
+
+  CREATE TABLE `blocks` (`pos` INT NOT NULL PRIMARY KEY,`data` BLOB);
+
+The key
+--------
+"pos" is created from the three coordinates of a MapBlock using this
+algorithm, defined here in Python:
+
+  def getBlockAsInteger(p):
+      return int64(p[2]*16777216 + p[1]*4096 + p[0])
+  
+  def int64(u):
+      while u >= 2**63:
+          u -= 2**64

+
+The blob
+---------
+The blob is the data that would have otherwise gone into the file.
+
+See below for description.
+
+MapBlock serialization format
+==============================
+NOTE: Byte order is MSB first (big-endian).
+NOTE: Zlib data is in such a format that Python's zlib at least can
+      directly decompress.
+
+u8 version
+- map format version number, this one is version 22
+
+u8 flags
+- Flag bitmasks:
+  - 0x01: is_underground: Should be set to 0 if there will be no light
+    obstructions above the block. If/when sunlight of a block is updated
+    and there is no block above it, this value is checked for determining
+    whether sunlight comes from the top.
+  - 0x02: day_night_differs: Whether the lighting of the block is different
+    on day and night. Only blocks that have this bit set are updated when
+    day transforms to night.
+  - 0x04: lighting_expired: If true, lighting is invalid and should be
+    updated.  If you can't calculate lighting in your generator properly,
+    you could try setting this 1 to everything and setting the uppermost
+    block in every sector as is_underground=0. I am quite sure it doesn't
+    work properly, though.
+  - 0x08: generated: True if the block has been generated. If false, block
+    is mostly filled with CONTENT_IGNORE and is likely to contain eg. parts
+    of trees of neighboring blocks.
+
+u8 content_width
+- Number of bytes in the content (param0) fields of nodes
+- Always 1
+
+u8 params_width
+- Number of bytes used for parameters per node
+- Always 2
+
+zlib-compressed node data:
+- content:
+  u8[4096]: param0 fields
+  u8[4096]: param1 fields
+  u8[4096]: param2 fields
+- The location of a node in each of those arrays is (z*16*16 + y*16 + x).
+
+zlib-compressed node metadata list
+- content:
+  u16 version (=1)
+  u16 count of metadata
+  foreach count:
+    u16 position (p.Z*MAP_BLOCKSIZE*MAP_BLOCKSIZE + p.Y*MAP_BLOCKSIZE + p.X)
+    u16 type_id
+    u16 content_size
+    u8[content_size] (content of metadata)
+
+u16 mapblockobject_count
+- Always 0
+- Should be removed in version 23 (TODO)
+
+u8 static object version:
+- Always 0
+
+u16 static_object_count
+
+foreach static_object_count:
+  u8 type (object type-id)
+  s32 pos_x_nodes * 10000
+  s32 pos_y_nodes * 10000
+  s32 pos_z_nodes * 10000
+  u16 data_size
+  u8[data_size] data
+
+u32 timestamp
+- Timestamp when last saved, as seconds from starting the game.
+- 0xffffffff = invalid/unknown timestamp, nothing should be done with the time
+               difference when loaded
+
+u8 name-id-mapping version
+- Always 0
+
+u16 num_name_id_mappings
+
+foreach num_name_id_mappings
+  u16 id
+  u16 name_len
+  u8[name_len] name
+
+EOF.
+
+Format of nodes
+----------------
+A node is composed of the u8 fields param0, param1 and param2.
+
+The content id of a node is determined as so:
+- If param0 < 0x80,
+    content_id = param0
+- Otherwise
+    content_id = (param0<<4) + (param2>>4)
+
+The purpose of param1 and param2 depend on the definition of the node.
+
+The name-id-mapping
+--------------------
+The mapping maps node content ids to node names.
+
+Node metadata format
+---------------------
+
+1: Generic metadata
+  serialized inventory
+  u32 len
+  u8[len] text
+  u16 len
+  u8[len] owner
+  u16 len
+  u8[len] infotext
+  u16 len
+  u8[len] inventory drawspec
+  u8 allow_text_input (bool)
+  u8 removal_disabled (bool)
+  u8 enforce_owner (bool)
+  u32 num_vars
+  foreach num_vars
+    u16 len
+    u8[len] name
+    u32 len
+    u8[len] value
+
+14: Sign metadata
+  u16 text_len
+  u8[text_len] text
+
+15: Chest metadata
+  serialized inventory
+
+16: Furnace metadata
+  TBD
+
+17: Locked Chest metadata
+  u16 len
+  u8[len] owner
+  serialized inventory
+
+Static objects
+---------------
+Static objects are persistent freely moving objects in the world.
+
+Object types:
+1: Test object
+2: Item
+3: Rat (deprecated)
+4: Oerkki (deprecated)
+5: Firefly (deprecated)
+6: MobV2 (deprecated)
+7: LuaEntity
+
+1: Item:
+  u8 version
+  version 0:
+    u16 len
+    u8[len] itemstring
+
+7: LuaEntity:
+  u8 version
+  version 1:
+    u16 len
+    u8[len] entity name
+    u32 len
+    u8[len] static data
+    s16 hp
+    s32 velocity.x * 10000
+    s32 velocity.y * 10000
+    s32 velocity.z * 10000
+    s32 yaw * 1000
+
+Itemstring format
+------------------
+eg. 'default:dirt 5'
+eg. 'default:pick_wood 21323'
+eg. '"default:apple" 2'
+eg. 'default:apple'
+- The wear value in tools is 0...65535
+- There are also a number of older formats that you might stumble upon:
+eg. 'node "default:dirt" 5'
+eg. 'NodeItem default:dirt 5'
+eg. 'ToolItem WPick 21323'
+
+Inventory serialization format
+-------------------------------
+- The inventory serialization format is line-based
+- The newline character used is "\n"
+- The end condition of a serialized inventory is always "EndInventory\n"
+- All the slots in a list must always be serialized.
+
+Example (format does not include "---"):
+---
+List foo 4
+Item default:sapling
+Item default:sword_stone 1 10647
+Item default:dirt 99
+Empty
+EndInventoryList
+List bar 9
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+Empty
+EndInventoryList
+EndInventory
+---
+
+==============================================
+Minetest World Format used as of 2011-05 or so
+==============================================
+
+Map data serialization format version 17.
+
+0.3.1 does not use this format, but a more recent one. This exists here for
+historical reasons.
+
+Directory structure:
+sectors/XXXXZZZZ or sectors2/XXX/ZZZ
+XXXX, ZZZZ, XXX and ZZZ being the hexadecimal X and Z coordinates.
+Under these, the block files are stored, called YYYY.
 
 There also exists files map_meta.txt and chunk_meta, that are used by the
 generator. If they are not found or invalid, the generator will currently
