Вот скрипт Python для ArcGIS 10, который в основном делает то, что вы хотите, за исключением того, что выводом является файл CSV, а не таблица базы геоданных. Не стесняйтесь изменять и использовать по своему усмотрению. Обратите внимание, что он не очень хорошо протестирован и не поддерживается, поэтому используйте его на свой страх и риск.
"""
This script looks through the specified geodatabase and reports the
names of all data elements, their schema owners and their feature
dataset (if applicable). Certain metadata elements such as abstract,
purpose and search keys are also reported.
The output is a CSV file that can be read by Excel, ArcGIS, etc.
Only geodatabases are supported, not folder workspaces.
Note: If run from outside of ArcToolbox, you will need to add
the metadata tool assemblies to the Global Assembly Cache.
See: http://forums.arcgis.com/threads/74468-Python-Errors-in-IDLE-when-processing-metadata
Parameters:
0 - Input workspace (file geodatabase, personal geodatabase,
or SDE connection file)
1 - Output CSV file
