STATUS UPDATE: Started (TAsn) working on it, did a lot of progress (look in opimd-redesign branch if you want), removed the backend system completely, now using only sqlite. Types are now stored in db. You can now pass multiple options per field, i.e query for all the contacts that their name is Tom, Dick or Harry. You can now query by type using the special prefix $. You just use $type_name as if it was a field_name and everything else is the same.
This page will gather all the suggestions (and will be a decent design sketch) for the redesign of opimd. After many discussions in IRC we decided opimd needs a redesign.
Main topics that came up are: switching opimd to use sqlite for internal operations and adding configuration for types instead of the use of URIs. Many of the ideas that came up concerning the second idea are represented in this IRC log: http://pastebin.com/mb7fbf10 and in the logs from #openmoko-cdevel@Freenode on 09-10 of october 2009.
Furthermore, it has been suggested than a change in the sqlite backend db design is also needed.
Info about those changes will be shown here as soon as we'll have time to write it down.
Remove the backend system, use only sqlite. Let 3rd party software (pisi?) handle backends (importing and exporting). This will be a lot faster and a lot esaier to handle. Furthermore, it'll finally let us have a permanent contact id to use internally (for linking between contacts for example).
Changes in fields
UPDATE: What we decided to go with: (now implemented)
IMPORTANT: This change invalidates the uri prefixing ("tel:" in phone numbers) that was used in opimd up until now.
org.freesmartphone.PIM.Type.Add(name, type) <--- Adds the name and type
org.freesmartphone.PIM.Type.List() <---- returns the list of available fields, format name:type.
org.freesmartphone.PIM.Type.Delete(name) <-- returns nothing
org.freesmartphone.PIM.Type.Get(name) <--- returns the type of the field.
General for all of opimd:
org.freesmartphone.PIM.Types.List() <---- returns the list of available types in a tuple.
Types.List() returns the same thing for all the domains.
This is the complete API (in freesmartphone docs). There are a couple of default fields, those fields can be overwritten, but if no value exists for them, they are used (also listed in the docs)
How to use: You can just use opimd like you have used it until now. BUT if you want opimd to work with number resolving (or any other field handling) you should add a matching type. So let's say to add support for the "Cellphone" field, we'll just have to:
or for supporting "Nickname" we'll have to:
This will let opimd assume things about the values inside (for instance assume that phonenumber is important and should probably be an indexed property). But also will let you (and more importantly the UI apps) work in a sane number knowing the types (and let's say, adding icons per type).
The Types.List() is just for helping you know what's currently supported in opimd.
As I said, you can still use fields without types, but then the apps (and opimd) will not be able to search them correctly.
- Enable querying by type, i.e, query where "phonenumber" = 123 will search in all the fields that have the type phonenumber.
Changes in query method
NOTE: keep the old way, but also implement this:
I don't get why we use this querying method, it just makes everything weird hard to handle.
Furthermore, it'll be easier and faster to get only "phone number" fields for matching (in opimd), the user of the API will just be able to tell it "find me a phone_number field that matches this number" and will not force us to check each field like we do atm.
opimd should internally use sqlite and sqlite only.
It should really be possible to ask opimd for several contacts at once, i.e ask him for the contacts "Tom, dick and harry" or for the numbers "123, 435 and 546546" at one query, because querying opimd for 70 different contacts at one time (phonelog) is terribly slow.
Furthermore it should be able to ask for a "join" of backends when requesting from one. i.e, I want to be able to ask opimd for the messages and the corresponding contacts for each message in one query, or even ask opimd for all the messages that match all the numbers from the contact "Charley".
Query reply should be possible to sort differently depending on the national character encoding.
