New Concall number for weekly calls
by Dries Kimpe 15 Mar '12

15 Mar '12

Hi, as mentioned during the API discussion today, I would like to propose we use a different concall number for the weekly status calls. The reason: - Many people seen to experience bad sound quality - I cannot call in for free when working remotely (meaning doesn't work with google voice and possibly other phone alternatives) The downside to switching would be that the new concall number does not come with a toll-free number. Does anybody have a problem with that? Thanks, Dries

Attribute query api strawmen
by Settlemyer, Bradley W. 15 Mar '12

15 Mar '12

Hello If there is a chance on the phone call, I am likely to want to discuss the followng possible api's for searching by attribute: object_cursor find(attribute_name) object_cursor find(attribute_name, value) object_cursor find_equal(attribute_name, value) object_cursor find_like(attribute_name, value) object_cursor find_as_int(attribute_name, value) object_id find_first(attribute_name) object_id find_last(attribute_name) It's not hard to see that there are about a thousand different permutations, but I think the interesting question is interpreting attributes as types (for example doing string matching with SQL like functionality, and what type of object cursors can be provided). Cheers, Brad
