[Opensim-dev] SceneObject* Metadata

[Frisby, Adam]

Well,

If we save it in RexEntity - then every storage provider needs to recognise it. RexEntity does and will exist - however when it comes to packaging the data up and putting it in a storage provider, we then need to make customised versions for each. The metadata field provides a convenient way of storing the extra properties in a backwards compatible way.
