[Midas] duplicate filename items?

[Michael Grauer]

Hi Mona,

I worked through these API calls of yours, they seem reasonable and that
they wouldn't change the item name.

One thing to consider, midas.item.create can be used to create an item, or
modify an existing item.  "name" is a required param whether you are
creating or editing, but if you are editing, and you pass a different name
than the original name, the name of the item will be changed.  Is it
possible that sometimes you are not passing up the (20) extension with the
name and hence changing the name of the item when adding the metadata?

We've added the API calls for item.setmetadata and
item.setmetadatamultiple, you could use those instead of item.create to set
your metadata, assuming your server version has these API calls.  This
would at least eliminate the chance of accidentally renaming.

Thanks,
Mike
