Introduction

The OpenSimulator inventory service stores user inventory data (object items, notecard items, folders, etc.) and provides this on request. Note that every inventory item points towards an immutable asset entry that actually contains the data.

The current default ROBUST OpenSimulator inventory service is known as the XInventoryService.

API

General notes

Unlike the asset service, the xinventory service is an RPC interface. Therefore it exposes only one URI which is xinventory (e.g. http://localhost:8003/xinventory). The invocation of different operations (e.g. add item, get item) is controlled via a METHOD parameter.

Formats

The API calls below return folder and item data in the same format. These formats are detailed below.

Item

This has the form 

<item type="List">
  <AssetID>31f51766-4a99-4b59-9e53-61f436614c71</AssetID>
  <AssetType>6</AssetType>
  <BasePermissions>581639</BasePermissions>
  <CreationDate>1347487471</CreationDate>
  <CreatorId>efc1b932-20e3-4298-8824-0f891fe3dc59</CreatorId>
  <CreatorData/>
  <CurrentPermissions>581639</CurrentPermissions>
  <Description/>
  <EveryOnePermissions>0</EveryOnePermissions>
  <Flags>0</Flags>
  <Folder>859723cf-6338-497b-ab70-64ca04b64f70</Folder>
  <GroupID>00000000-0000-0000-0000-000000000000</GroupID>
  <GroupOwned>False</GroupOwned>
  <GroupPermissions>0</GroupPermissions>
  <ID>25e16367-accd-4b92-8f46-b55d3f63ad0d</ID>
  <InvType>6</InvType>
  <Name>Primitive</Name>
  <NextPermissions>581632</NextPermissions>
  <Owner>efc1b932-20e3-4298-8824-0f891fe3dc59</Owner>
  <SalePrice>0</SalePrice>
  <SaleType>0</SaleType>
</item>

where

  • AssetID is the UUID of the asset for this inventory item (e.g. the actual serialized object data for a primitive).
  • AssetType is the asset type of this item. See the AssetType enum in libopenmetaverse for more details. In this case the asset type is 6 to denote an object.
  • BasePermissions the base permissions for the item. See the Permissions flags enum in libopenmetaverse for more details.
  • CreationDate is the unix time stamp of the creation date of the item.
  • CreatorId is the UUID of the creator.
  • CreatorData is extended creator data information for the item (as used by the --creators option in the "save iar" command). This may be blank.
  • CurrentPermissions are the permissions that the current owner has over the item when rezzed. See the Permissions flags enum in libopenmetaverse for more details.
  • Description is the description of the item. This may be blank.
  • EveryOnePermissions are the permissions that anyone would have over the item when rezzed. See the Permissions flags enum in libopenmetaverse for more details.
  • Flags is an integer flags entry. May be blank. Needs documentation.
  • Folder is the UUID of the folder containing this item.
  • GroupID is the UUID of the group that owns this item, if any. If there is no owner then this is UUID.Zero (00000000-0000-0000-0000-000000000000).
  • GroupOwner is true if the item is group owned, false if not.
  • GroupPermissions are the group permissions for the item, if applicable. See the Permissions flags enum in libopenmetaverse for more details.
  • ID is the UUID of the item.
  • InvType is the inventory type of the item. See the InventoryType enum in libopenmetaverse for more details. In this case the inventory type is 6 to denote an object.
  • Name is the name of the item.
  • NextPermissions are the permissions that the next owner of this item will receive.
  • Owner is the UUID of the owner of this item
  • SalePrice is the sale price of this item.
  • SaleType is the sale type of this item. See the SaleType enum in libopenmetaverse for more details.

In some cases where multiple items can be returned the item element will have an underscore and index value appended (e.g. item_0 instead of folder). This is for historical reasons.

Folder

This has the form 

<folder type="List">
  <ParentID>00000000-0000-0000-0000-000000000000</ParentID>
  <Type>9</Type>
  <Version>1</Version>
  <Name>My Inventory</Name>
  <Owner>efc1b932-20e3-4298-8824-0f891fe3dc59</Owner>
  <ID>035f457b-a0f6-4580-a10c-e4f908e176ac</ID>
</folder>

where

  • ParentID is the parent folder ID. For the root ("My Inventory") folder this is always UUID.Zero (00000000-0000-0000-0000-000000000000).
  • Type is the type of the folder. See the InventoryType enum in libopenmetaverse for more details. In this case, the type is 9 (RootCategory) since this is a root folder.
  • Version is the version of the folder. This is used for viewer inventory caching purposes.
  • Name is the name of the folder.
  • Owner is the UUID of the avatar that owns the folder.
  • ID is the unique id of the folder itself.

In some cases where multiple folders can be returned the folder element will have an underscore and index value appended (e.g. folder_0 instead of folder). This is for historical reasons.

Calls

GETROOTFOLDER

This returns data about a user's root folder (i.e. their "My Inventory" folder"). POST field is a urlencoded string like so 

PRINCIPAL=efc1b932-20e3-4298-8824-0f891fe3dc59&METHOD=GETROOTFOLDER

where

  • METHOD is GETROOTFOLDER
  • PRINCIPAL is the UUID of the user

If successful, example return is 

<?xml version="1.0"?>
<ServerResponse>
  <folder type="List">
    <ParentID>00000000-0000-0000-0000-000000000000</ParentID>
    <Type>9</Type>
    <Version>1</Version>
    <Name>My Inventory</Name>
    <Owner>efc1b932-20e3-4298-8824-0f891fe3dc59</Owner>
    <ID>035f457b-a0f6-4580-a10c-e4f908e176ac</ID>
  </folder>
</ServerResponse>

If the request fails (e.g. because the PRINCIPAL does not exist) you will receive an empty response 

<?xml version="1.0"?><ServerResponse />

See #Folder for more details about the folder format.

Sample scripts 

<?php
 
    $ch = curl_init("http://localhost:8003/xinventory");
 
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, "PRINCIPAL=efc1b931-20e3-4298-8824-0f891fe3dc59&METHOD=GETROOTFOLDER");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
 
    $result = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
 
    echo "Return code:" . $info['http_code'] . "\n";
    echo "$result\n";
 
?>

GETFOLDERFORTYPE

This returns data about the user's system folder for a particular type (e.g. their "Clothing" system folder). POST field is a urlencoded string like so 

PRINCIPAL=efc1b932-20e3-4298-8824-0f891fe3dc59&TYPE=13&METHOD=GETFOLDERFORTYPE

where

  • METHOD is GETFOLDERFORTYPE
  • PRINCIPAL is the UUID of the user
  • TYPE is the type of system folder to get. See the AssetType enum in libopenmetaverse for more details. In this case the asset type is 13 for the body parts sytem folder.

If successful, example return is 

<?xml version="1.0"?>
<ServerResponse>
  <folder type="List">
    <ParentID>035f457b-a0f6-4580-a10c-e4f908e176ac</ParentID>

    <ID>40506578-704d-49bb-adbc-98b2c4719fb2</ID>
  </folder>
</ServerResponse>

If the request fails (e.g. because the PRINCIPAL does not exist) you will receive an empty response 

<?xml version="1.0"?><ServerResponse />

See #Folder for more details about the folder format.
