Description

This script generates the XML files needed to create a new asset set and associated inventory libraries for OpenSim.Given a directory tree of jp2 and lsl files, and it will traverse the tree and generate the assets file, the inventory folder file, and the inventory items file.

Usage

• Put the code in a file named genassets.pl, and copy it to your library preparation directory (/opt/opensim/library)
• Download the perl UUID module
• Install the UUID module

perl Makefile.PL
make
make test
make install

• Create Asset directories

mkdir /opt/opensim/production/bin/inventory/MyCoolOpenSimLibrary/
mkdir /opt/opensim/production/bin/assets/MyCoolOpenSimAssetSet/

• Launch script (Adds the content in /opt/opensim/production/library to the OpenSim inventory/asset storage)

perl /opt/opensim/production/library/genassets.pl
