Status in Zeitgeist Framework: New Bug description: I just reviewed the latest API additions with the ZeitgeistClient.get_uris_most_used_with* and corresponding methods inside the engine. Sorry to be a party-spoiler, but I think there is some stuff that needs cleanup before we can roll 0.3.1. The technical issues I found off the bat: 1. Using the prefix get_* for all of these most-used queries seems a bit off since you are not retrieving a well known thing, but are querying and getting an unpredictable result. I'd prefer if we used find_everywhere instead. 2. The method names also use the *_with_* word where we have used *_for_* everywhere else in the code hitherto. 3. Why do these new methods return URIs and not Subject instances? 4. The DBus method GetMostUsedWithSubjects has a misleading name. It doesn't take a list of subjects in the args. 5. Why is the time_range arg. not the first arg like it is for FindEventIds()? Then there's something about this API that just tells me it is wrong: I. Why is there no paging? The API allows me to do very broad queries, like "give me anything related to subjects of interpretation Document" which would presumably have huge result sets? II. Assuming there can be many results why doesn't it return a list of event ids, like FindEventIds()? III. Using "MostUsed" in the name more or less implies that which algorithm will be used. Do we want that? Is it better for forwards compatibility to use the more generic term "Related"? All of these questions leads me to think that we really need an API like: FindRelatedEventIds(in (xx) time_range, in aE event_templates, in aE related_event_templates, in u storage_state, in u num_events, in u result_type out au related_event_ids) The result_type could change the way results are ordered, much like our current FIndEventIds(), but not exactly the same switches. Maybe result_type could be: 0 : Results ordered by relevancy (where the exact measure of relevancy is up to the engine) 1 : Results ordered by recency _______________________________________________ Mailing list: https://launchpad.net/~zeitgeist Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~zeitgeist More help : https://help.launchpad.net/ListHelp
