Steven Hawkins updated TEIID-2715:
----------------------------------
Issue Type: Enhancement (was: Bug)
Workaround Description: Create a view that contains the desired properties by joining
against the properties table.
Workaround: Workaround Exists
Switching to an enhancement as given the current structure of the system schema there
isn't an inherent issue now that TEIID-2718 has been resolved.
The general question here is about the usability of extension metadata from odata. There
isn't currently a good relationship between the properties table and all of the object
type tables.
The workaround is to have the user create a view to denormalize the properties how ever
they see fit.
As for built-in work, to expose the extension properties a little more naturally we could
add columns to the properties table so that it can be queried by something other than uid,
or add navigatable relations like table_properties. There may also be something in
odata's metadata that will allow arbitrary properties - although I did not see that at
first glance.
Created and registered MXD, extra metadata is not visible when
queried.

Issue Type: Enhancement
Components: Server
Affects Versions: 8.6
Environment: Windows 7
Reporter: Alex Khvatov
Assignee: Steven Hawkins
x`Hi,
I used Teiid Designer and just plain XML editor (because Teiid Designer would constantly
complain) I created Model Extension Definition file which I was able to successfully
register. My definition was showing up in Model Extension Registry view. I deployed my
virtual database and tried accessing columns and tables via Odata:
http://localhost:8080/odata/MCR_VDB/Tables?$format=json
http://localhost:8080/odata/MCR_VDB/Columns?$format=json
Both documents returned did not contain any extra metadata I defined.
HELP!
Thanks.
Alex
