MetaTagger from WorkFlow?

System

Hi,
We are using W2K, TeamSite 5.5.2 sp3, MetaTagger 3.5.

We are trying to find the best way to integrate using MetaTagger into a workflow. What are some options on this? One thing we thought of was:

a) user uploads a new image via TeamSite GUI.
b) they checkmark the file and then start a new workflow.
c) the workflow will launch MetaTagger and the person tags it with metadata.
d) after hitting "close" on the MetaTagger GUI, the workflow takes over automatically and does an external task on the file.

We'd rather not have the person kick off MetaTagger themselves, but instead have it part of the workflow. Item "d" would be really nice to have, but I'm not sure how it would work.

Are there any ideas for doing this? Thanks,

David
