David C. Hay's Universal Data Model:

Say, has anyone out there given much thought to the design of a Universal Data Model? Something along the lines of the one found in David Hay's book "Data Model Patterns"
(pg 256 for those who have it)

The data model had the following tables: Attribute
Attribute Assignment
Value
Relationship
Relationship Type

Value

| |

     Relationship-------- Thing ----------------------|    |
             |        | ---------  |


|

          |                        |


|

             |                        |       Attribute Assignment    |
    Relationship             |          |                         |        |
        Type                     |          |                         |

                                 Thing Class                    Attribute

I'd really be interested on any thoughts on further refinements to the above model.

(this is my first time in this newsgroup, and I am really impressed with the quality of advice given)

Thanks in advance,
