=== How do I create access the metadata entries for a datastore object? ===
Every DSObject created by datastore.create() has a metadata property. This property refers to a [[#Class: DSMetadata | DSMetadata object]], which contains the metadata for your datastore object. The code below shows how to read metadata values by referring to the metadata property of a DSObject. metadata is a Python dictionary object.
<pre>
from sugar.datastore import datastore
...
#my_dsobject is of type datastore.DSObject
#object_id is a datastore object (returned from the datastore Chooser
my_dsobject = datastore.get(object_id)
#Access the 'description' property
print my_dsobject.metadata['description']
#other standard objects in the metadata dictionary include 'tags',
</pre>
