[topicmaps-comment] TAO vs. ERA

[Scott Tsao <skst4xml@yahoo.com>]

In a recent presentation of TopicMaps, the audience
was able to relate the TopicMaps paradigm
(topic-association-occurrence) to a more traditional
data modeling paradigm, namely, ERA
(entity-relationship-attribute), where topic
corresponds to entity, association corresponds to
relationship, and occurrence corresponds to attribute.
 While this mental mapping helped their understanding
(and hopefully acceptance) of the TopicMaps paradigm,
I was trying to come up with something that could
prove that TopicMaps is significantly different (and
better) than ERA.  Do you have any suggestion?  Is
TopicMaps merely a newer version of ERA for the Web?

Thanks,

Scott
