Query objects by metadata
|Reported by:||wnorris||Owned by:|
The new metadata API makes it very easy to get metadata for a known object. For example, operations like "Give me the last name for the user #12", or "show me all email addresses that are subscribed to comments on post #4".
However, it does not provide an easy way to look up objects based on metadata keys or values. For example, things like "show me all posts the email address 'foo@…' is subscribed to receive comments for". Or "show me all posts that have a 'mood' custom value set, regardless of value". Or (my personal itch), "what user is associated with the OpenID 'http://foo.com'?"
This kind of querying ability would be immensely useful to plugin authors.
