Subject Re: CAS Curator - No metadata detected
Date Thu, 09 Feb 2012 19:48:34 GMT
Hi Chris,

Actually, it turns out that the python script was not able to write .met
file to the intended directory because of a permission issue. As soon as I
fixed the permissions, it started working.

I noticed that .met files are created in both products/mp3 and metadata/mp3
folder. Is there a reason why .met file is created in products/mp3? Because
of this, on a web app page refresh, .met files also show up in the staging
area.

Thank you,
Peyush
