Cool. Matthias put me down as Owner of that feature, because I will be spending lots of work time on it to get something good for 3.2. However, I'm kind of a newbie in this area, so I'd like to start reaching out to the involved parties and take a look at the technologies involved and their status. It seems like we have lots of interest and momentum from the telepathy/folks/socialweb side. Do we also have interested parties from the evolution side? I think having this deeply integrated with evolution is as important as the IM/social side. Ideally we should be replacing the evolution address book UI with this. * Folks has a nearly-ready read-only e-d-s backend [2] * making this read-write should be straightforward, since we did that with our Tracker backend This sounds excellent. It seems to me that we should default for this to be the main writable store, and avoid using the keyfile backend. Its our primary local contact store anyway, so why not also use it to link to other personas. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexander LarssonRed Hat, Inc al...@redhat.comalexander.lars...@gmail.com He's a scrappy Jewish shaman on the edge.

So, I guess we need to think about where it fits in. Hmm, its really not that tricky - the eventually consistent method used by couch works well in most situations - all replicated endpoints resolve to the same state without intervention, and if you want to pick up any pieces, you can. I would be happy to help out any team forming to look at the area - at work we've had a few people building replicating (mobile/server) apps with couchdb and it's a very nice system. Also, semi-schema'd document based storage like couch works nicely for extensibility and data mashups. On supporting existing sync protocols, for 'traditional' sync, its important to have one central point of resolution, and that's ideally a server. A nice plan would be a server side component (on gnome.org of course) that has an activesync and syncml endpoint which syncs into a couchdb database for replication with the desktop. For activesync, z-push [1] works well, and can be made pretty scalable with a few changes. for SyncML, there's good open source components like funambol [2] available. I'd probably be able to swing some sponsorship for hosted servers if we can put together a team looking at this.

I don't think we want to have synchronization as some core part of the design. On the other hand, its important that there is some level of support for synchronizing contacts with e.g. phones. So, I guess we need to think about where it fits in. If I had one wish, then it is this one: ensure that each item gets a unique, vendor created ID that never changes throughout the lifetime of the item. Currently EDS supports that for calendar (part of iCalendar 2.0 semantic), but not in the file contact backend (not required by vCard 3.0). Any UID that might have been set in a new vCard is overwritten by a local ID. Hmm, its really not that tricky - the eventually consistent method used by couch works well in most situations - all replicated endpoints resolve to the same state without intervention, and if you want to pick up any pieces, you can. For couchdb-couchdb sync, yes, but that's only a subset of the problem - unless you can convince the rest of the world to use the same system. Start by convincing the Tracker/Ontology proponents, who also want everyone else to use their system for data replication ;-) I'm pragmatic and don't expect that any system will ever take over enough to use it exclusively. Regarding couchdb: how complete is its data model? When it first showed up, SyncEvolution had some problems with it because REV wasn't supported, if memory serves me right. On supporting existing sync protocols, for 'traditional' sync, its important to have one central point of resolution, and that's ideally a server. Then the server becomes easily the weakest link in the chain. In the past, dumb phones had a very limited data model that could be completely supported by a (SyncML) server. Nowadays the address book in a client is very rich and may contain data that is not supported by many servers - that's definitely the case with, for example, MeeGo to Google sync. If the client then trusts the server exclusively to resolve conflicts, data is lost on the server. Another conceptual problem is that the server cannot communicate well with the user. A client might pop up rich dialogs and ask the user for help in cases that it cannot decide automatically (but designing such a dialog is an unsolved problem). SyncML servers (and probably other servers, too) don't have that option and instead fall back to heuristics which fail inevitably in some cases. A nice plan would be a server side component (on gnome.org of course) that has an activesync and syncml endpoint which syncs into a couchdb database for replication with the desktop. For activesync, z-push [1] works well, and can be made pretty scalable with a few changes. for SyncML, there's good open source components like funambol [2] available. I personally would rather recommend the Synthesis engine instead of Funambol. Much more light-weight and miles ahead Funambol regarding SyncML support and data merging (for example, supports suspend/resume and much smarter conflict resolution).

Online Accounts panel for 3.2
Hey, One of the things I'm looking at doing for 3.2 is the Web Accounts panel: http://live.gnome.org/ThreePointOne/Features/Sharing http://live.gnome.org/Design/SystemSettings/Profile I sat down last week with one of the designers, Jon McCann, and we came up with what we both think is a really nice user experience. It is described in [1] for now - will move to the wiki soon. Implementation-wise, I can see this as a very minimal daemon / library that sits below libsocialweb, Telepathy, e-d-s and other APIs (e.g. these libraries/frameworks would use this new framework) that is dealing data online accounts. This daemon / library would a. have a notion of source types - email source - calendar source - chat source - photos source - contacts source - ... b. have a notion of providers that can be added removed by the end user - Google (for accounts at google.com and Apps For Your Domain) - Yahoo/Flickr - Exchange - Facebook - ... c. provide a concrete list of providers and what sources the instance of the provider supports. For example, for my setup, I would have the following - zeut...@gmail.com (an instance of the Google data provider) - Mail (email source) - Contacts (contacts source) - Calendar (calendar source) - Chat (chat source) - da...@fubar.dk (an instance of the Google data provider) - (works because fubar.dk is using Google Apps For Your Domain) - Mail (email source) - dzeut...@yahoo.com (an instance of the Yahoo! data provider) - Flickr! (photos source) - (I specifically unchecked mail here because I don't want the spam that is in that email account that I never use) - davidz25 (an instance of the Facebook data provider) - Messages (email source) - Events (calendar source) The information in c. would map exactly to what the Web Accounts UI would display: +--+ | All Settings | +--+ | +---+ Google Account| | | [Go] zeut...@gmail.com|| | | [Go] da...@fubar.dk (!) | Username: david | | | [Y!] dzeut...@yahoo.com | Domain: fubar.dk_ | | | [Fb] davidz25 || | | | Use this account for: | | | || | | | [ON ] Mail | | | | [ OFF] Chat | | | | [ OFF] Contacts | | | | [ OFF] Calendar | | | || | +---+ (!) Authorization expired. | | | [+] [-] | Please login again.| | +---+[Login] | +--+ This screenshot shows an example where the da...@fubar.dk account needs attention (suppose that the password has been changed from another system). In this case, I think the desktop would show the user a notification saying The account da...@fubar.dk needs your attention and upon clicking on it, the user is taking to the control-center pane above. This daemon/library thing, let's call it GOA (Gnome Online Accounts), would _not_ be a mechanism to access any of these services. But it would provide e.g. libsocialweb, telepathy, e-d-s and so on with either the username/password combo or the OAuth token, whatever is appropriate. I would imagine Telepathy/Empathy to use GOA to get the Chat accounts that is configured in GOA (in the above example, it would be Google Talk from zeut...@gmail.com and Facebook Chat for davidz25). I would use an Empathy specific preferences window (not appearing in gnome-control-center I think) to add e.g. my ICQ account. There are of course security / implementation considerations (password/auth token hygiene, should we treat the desktop like it's not a single security context when it really is?) here - all of that comes next. Technically, I'm proposing that we add a GOA module with - a daemon, goad, that implements the org.gnome.OnlineAccounts interface on a well-known object /org/gnome/OnlineAccounts and owns the well-known name org.gnome.OnlineAccounts (all this is on the session bus). Additionally, this daemon would notify the user if attention is needed (e.g. reauth) using org.freedesktop.Notificatins / libnotify. - a library, libgoa-1.0, that is used to speak to goad (but an app can also just use the D-Bus interface if it wants to).

We already have all of this (and more) in MeeGo, and I'm willing to support any efforts in bringing this to Gnome. I sat down last week with one of the designers, Jon McCann, and we came up with what we both think is a really nice user experience. It is described in [1] for now - will move to the wiki soon. Implementation-wise, I can see this as a very minimal daemon / library that sits below libsocialweb, Telepathy, e-d-s and other APIs (e.g. these libraries/frameworks would use this new framework) that is dealing data online accounts. In MeeGo we chose two split the thing into two: account framework, which simply consists of descriptions of providers and sources (which we call services), and a library wrapping a SQLite DB for accounts settings, where applications can read/store accounts settings (not the passwords). The provider and services are described by XML files, which can be installed in predefined directories. This allows for expandability: to support a new service, you just need to install a package which adds a service XML file. The service XML files not only describe the service (icon, name and provider) but also contain a default value for account settings; the account library uses these settings as fallback when a settings has not been explicitly written in the DB -- this is all transparent to the application. The point of this is that you don't want to ask the user for the address of the IMAP server of GMail: we can write it in the service XML file. The accounts library support change notification via D-Bus, so that when a setting in the GMail account has been modified, all applications interested in the e-mail service type are notified and can reconnect the account. This daemon / library would a. have a notion of source types - email source [...] b. have a notion of providers that can be added removed by the end user - Google (for accounts at google.com and Apps For Your Domain) [...] c. provide a concrete list of providers and what sources the instance of the provider supports. For example, for my setup, I would have the following - zeut...@gmail.com (an instance of the Google data provider) - Mail (email source) - Contacts (contacts source) - Calendar (calendar source) - Chat (chat source) [...] It's similar to what we have, except that we don't hardcode the list of available sources in the provider file. It's the source, who tells what provider (and source-type) it belongs to. This screenshot shows an example where the da...@fubar.dk account needs attention (suppose that the password has been changed from another system). In this case, I think the desktop would show the user a notification saying The account da...@fubar.dk needs your attention and upon clicking on it, the user is taking to the control-center pane above. Mmm... that's one option, though I'd rather like that by clicking on the notification you directly go to the login screen where you can enter your password. And one thing that I heartily recommend you based on experience: do *never* let the user change the username once the account has been created. This saves you a lot of trouble. This daemon/library thing, let's call it GOA (Gnome Online Accounts), would _not_ be a mechanism to access any of these services. But it would provide e.g. libsocialweb, telepathy, e-d-s and so on with either the username/password combo or the OAuth token, whatever is appropriate. And for this we have the SSO framework in MeeGo. It's one daemon, that stores the user credentials on an encrypted partition which is mounted only when the user is identified (in our device we'll use the SIM card for this goal, in the Gnome desktop it could be the lock-screen password). Passwords are generally not given back to applications; instead, signond (the SSO daemon) loads a plugin specific to the authentication method being used (SASL, OAuth, Google, etc.): the plugin gets the passwords, and uses it to compute a response to give back to the client. This response can be a response that the client must give back to the remote server in a SASL challenge, or a token that can be used to login. In cases where the authentication plugin performs the authentication with the remote server, in case the password is wrong it will itself inform signond, which in turn will invoke a UI to prompt the user for a new password. If instead the plugin is simply computing responses without having knowledge if the password is correct, the application will get an error and it can retry the authentication with a flag which tells signond to ask the user for a new password before computing the response.

Nothing will be for free once you want to add interoperability :-/ All of the challenges mentioned in the article above will still apply (no unique ID in those peers, legacy formats, different data models). then there is also the idea of having a webservice for the gnome contacts app, where you can access your contacts over the internet. we are very interested in your opinions about this! I don't know really. Synchronization is a tricky subject, with complex protocols and risk for merge problems. Its almost always a source of weird problems. I don't think we want to have synchronization as some core part of the design. On the other hand, its important that there is some level of support for synchronizing contacts with e.g. phones. So, I guess we need to think about where it fits in. If I had one wish, then it is this one: ensure that each item gets a unique, vendor created ID that never changes throughout the lifetime of the item. Currently EDS supports that for calendar (part of iCalendar 2.0 semantic), but not in the file contact backend (not required by vCard 3.0). Any UID that might have been set in a new vCard is overwritten by a local ID. Hmm, its really not that tricky - the eventually consistent method used by couch works well in most situations - all replicated endpoints resolve to the same state without intervention, and if you want to pick up any pieces, you can. For couchdb-couchdb sync, yes, but that's only a subset of the problem - unless you can convince the rest of the world to use the same system. Start by convincing the Tracker/Ontology proponents, who also want everyone else to use their system for data replication ;-) I'm pragmatic and don't expect that any system will ever take over enough to use it exclusively. Regarding couchdb: how complete is its data model? When it first showed up, SyncEvolution had some problems with it because REV wasn't supported, if memory serves me right. Since 1.0 it's been pretty sweet, with all the functionality working well - including live updates. On supporting existing sync protocols, for 'traditional' sync, its important to have one central point of resolution, and that's ideally a server. Then the server becomes easily the weakest link in the chain. In the past, dumb phones had a very limited data model that could be completely supported by a (SyncML) server. Nowadays the address book in a client is very rich and may contain data that is not supported by many servers - that's definitely the case with, for example, MeeGo to Google sync. If the client then trusts the server exclusively to resolve conflicts, data is lost on the server. Hmm, the actual problem here is not the server - its the representation format. I would argue that the correct approach to this is to always represent all the data you receive from clients - and transform the stuff you do understand in to a common representation. Another conceptual problem is that the server cannot communicate well with the user. A client might pop up rich dialogs and ask the user for help in cases that it cannot decide automatically (but designing such a dialog is an unsolved problem). SyncML servers (and probably other servers, too) don't have that option and instead fall back to heuristics which fail inevitably in some cases. Think of couch as a bit like git - you never resolve on the server. you effectively get a forking history, with a consistent algorithm to choose a winning version of history. That mean on the client

Hi! And for this we have the SSO framework in MeeGo.

The tool then generates a set of specially formatted GKeyFiles and deposits them into a designated user directory which E-D-S is monitoring. E-D-S then sees the new key files, parses them into ESource objects, and adds them to an internal registry. If a client like Evolution is running, it would also notice the new key files and immediately present them in its source list, usually shown in the sidebar.

In the process, Alban Crequy also added Contacts support for a few libsocialweb services in libsocialweb itself (Flickr, Twitter, Last.FM) and upstreamed Marco Barisione's Facebook support. The remaining lsw services (such as Vimeo and YouTube) don't have Contacts support yet, but it could certainly be added. this makes a lot of sense, but we really need a way to send messages to facebook/twitter contacts, or do other operations on the other services (see photos from flickr, listen to music in last.fm, etc). So, are there any plans for a twitter/facebook client app? None that I know of. We already support Facebook's XMPP chat through Telepathy but not its email-like messaging system. Can third party clients use that anyhow? I thought that was completely walled off. I'm not terribly familiar with the details of Twitter - it just supports 140-char global posts and private messages between users, right? Handling sending these messages is probably best implemented as protocol handlers for Evolution, since they don't quite fit in with Telepathy's model and I think libsocialweb avoids communication to keep its scope narrower.

The problem in the current situation is that the shell provides a nice chat integration but to start a new chat you have to use the Contact List window of empathy which feels totally out-of-place. It is also one of the windows you really don't want to see in the overview. Agreed. I'd like my general chat process to just be: Meta, start typing person's name+Enter By meta you mean the windows key thing? Right. which is the same way I launch all my applications in Gnome Shell (and is one of the most compelling features of it, I think). Like launching programs, you would be able to pause to see the full results list and perform more-specific actions (such as selecting the exact account and contact you want to initiate the chat from and to, as Empathy lets you do now). Yeah, this sounds like about the right thing. I'm thinking we could have a new tab in addition to the windows and applications one listing people, probably showing the online ones first, or at least making that information prominent. Clicking on a person should let you easily send mail, start a im conversation or send a file. Additionally these should show up on the search results, and be possible to put in the dash. Yeah, a people tab makes sense too. Note that FolksIndividuals (ie, people) can be marked as favorites. If it's feasible, it'd be nice to determine membership in the dash based on whether contacts are favorites, though we may want to confirm that users generally only set a few people as favorites, since the dash quickly gets crowded even just with programs. And I'm guessing we'd want a gap to separate programs and people. What Daniel and Salamon mocked-up is certainly a nice start but I think a dedicated window for it doesn't fit with the overall shell design well. I think it makes sense to have both. The shell search provider would focus on communicating with existing contacts (similar to launching programs), whereas the stand-alone program would be more focused on adding and managing contacts (which are much-rarer actions). And it still makes sense to have the communication buttons in the stand-alone program to make the use case of add a person, start chat/call with them smoother than adding them there, then going to the Activities tab to start the communication. Yeah, I think this is somewhat analogous to the file management situation. If you just want to find or open a file you can use the shell, but if you want to do more work you'd start the file manager. So, the gnome-shell integrated part is about day-to-day using of the already set up stuff, whereas the contacts app is where you'd fill in information, or do more complex stuff like link contacts or create groups. There are other integration points we must think about too. Whatever we come up with should imho replace the contacts pane in evolution, and must allow interaction with evolution (dnd onto composer windows, etc). Also, we should have something that corresponds to clicking on the to button in the evo compositor to select a single email (or im if used for elsewhere) address to add.
