Hi Aaron!

I was able to get over the route issue - to begin with, turns out there was
a nasty single space rogue indent in the file (peril of not using a good
IDE). Apart from that, stepping through the api/extensions.py code showed
that I shouldn't be overriding the get_plugin_interface() method in tag.py
- because I don't have a plugin associated with this, and would use the
current plugin. Also, there was an attributes variable I was using wrongly
- had imported it as attr and had to use that..

So the next steps for me would be to go ahead in implementing the logic to
check/write to the db. Hopefully I'll get that to work quicker.

Thanks a lot again!

Regards,
Vijay
