RE: Contacts API draft

Hi Christophe, all,

I have been comparing the two proposals on the table for Contacts API, and they happen to have more similarities than differences what is good news in order to reach a consolidated proposal. Let me comment on the main differences:

-Filtering: Intel's proposal allows applying virtually any type of filter as it allows the definition of composite filters. Note though that in order to have an appropriate performance the runtime will need to define indexes for the different filtering operations. Having so flexible filtering implies creating a virtually unlimited set of indexes. Christophe, what is the performance you expect the implementation to have? and how do you propose to solve that issue?

-ContactChangeEvent: Intel's proposal allows notifying changes in multiple contacts simultaneously indicating which contacts have been deleted, created and modified. Is the system expected to wait for some time before firing an event with multiple changes or do these notifications of multiple changes apply just to really simultaneous changes (e.g. sync with an external address book).

-getSimContacts(): Our proposal included this method to be able to retrieve the contacts from the SIM card (e.g. to copy them to the device address book). It is not the intention to deal in any other way with the SIM's address book, so neither the rest of the methods (find, remove, etc) nor the ContactChangeEvent apply in principle to SIM contacts.

-read-only contacts in Intel's proposal: Christophe, could you elaborate what is the use case for that?

-Additional fields in Intel's proposal: relationship, phoneticGivenName; phoneticFamilyName; favorite; ringtone


-Additional fields in our proposal: genderIdentity; carrier attribute in tel field

Any other relevant difference that I am missing?

Best regards,
Eduardo.

Asunto: Contacts API draft

Hi,

We have uploaded an initial draft proposal of the Contact API to:
http://sysapps.github.com/sysapps/proposals/contacts_intel/Overview.html

It is based on the corresponding Tizen and B2G APIs:
https://wiki.mozilla.org/WebAPI/ContactsAPI
https://developer.tizen.org/help/index.jsp?topic=%2Forg.tizen.web.device.apireference%2Ftizen%2Fcontact.html
https://developer.tizen.org/help/index.jsp?topic=%2Forg.tizen.web.device.apireference%2Ftizen%2Ftizen.html

For now, the Contacts and Filtering APIs are merged in one document (as requested by Adam Barth). However, the filtering API is generic and could be moved out of this specification if we wish to use it in other specifications as well.

We are looking forward to your feedback.

Kr,
