Introduction

There are many asset types in OpenSimulator (e.g. notecards, sounds, textures). Each of these has its own distinctive format.

On the whole, asset formats are identical to those used by the Second Life system, since they need to be sent to and understood by a second life client. However, some are unique to OpenSimulator, in particular the object/prim serialization format.

Object/prim serialization formats

There are currently two object formats in OpenSimulator - 'xml' and 'xml2'. These are semantically identical and physically almost identical - by a sad quirk of fate slightly different formats are used for different purposes (e.g. serialization to asset store and storage in OAR files).

XML format

Here's an example

XML2 format

Here's the same object as above, but in 'XML2' format. As you can see, the format is identical except that there is no <RootPart> tag around the root part - it is assumed to be simply the first part instead.
