I've found that both work. In practice, I always use the to-one and if I need a to-many I model it like this: Person ->> photo -> ERAttachment This way if you have any additional metadata to add about your attachment (in this case photo) that is not included in the default ERAttachment metadata, you're covered. If you don't foresee a need for additional metadata this also works: Person ->> ERAttachment (photos) HTH, David > > Thanks in advance, > > Johnny > > > Johnny Miller > Kahalawai Media Corp > http://www.kahalawai.com > > > > _______________________________________________ > Do not post admin requests to the list.
