OTrunk

• Object Trunk - this is a mechanism for storing and retreiving "objects"
• not intended for java objects
• Separate storage object is used: OTDataObject. Each OTObject in this system uses an OTDataObject to store and load its information
• each OTDataObject has a collection of resources. Resources can be: blob, boolean, sting, list, map, object id
• each OTDataObject has a UUID.
• Currently there are no transactions. As soon as a resource in a OTDataObject is modified this change perminent.
• The main implementation uses files with UUID for the file name data is a serialization of the OTDataObject.
  • there is also an ozone implementation. this might be useful if we want to have several programs accessing an OTrunk database at the same time.

• User Objects:
  • database implementation must implement User Object mapping
  • given a user and a object id . the database returns a OTUserDataObject.
  • if anything makes a change to this UserDataObject then a new DataObject will be created for that object.

• XML Import
  • basic import of data objects is hard to use.
    {{
    <OTDataObject>
    <Resource name=""></Resource>
    <Resource name=""></Resource>
    </OTDataObject>
    }}
