What's objtype "data" stand for?

Hi,
I'm willing to sync evolution contacts/calendars/memos/tasks into files. Default objtype for file-sync member as 'data'. Default objtype for evo2-sync member are 'contact', 'event', 'note' and 'todo'. I crated a group with default parameters. Trying to run --sync, nothing happens. Edit the file-sync member config file, remove 'data' part and comment out 'contact' part out. Try --sync agagin, the contacts can be synced from evolution. My understanding for 'data' concept is a special objtype, it can stands for 'contact', 'event', 'note', 'todo' and more like files. Jijun said he ever synced file and evo2 with objtype 'data', but now trunk code can not. So am i missing something here?

Correct - it's kind of "wildcard". > Jijun said he ever synced file and evo2 with objtype 'data', but now > trunk code can not. So am i missing something here? No - thats correct for now. With 0.3x we introduced the "objtype sinks" which allows complete seperation of the object types. Unfurtonately the file-sync can't handle right now the mix-up of object types - e.g. evo2-sync (contact) -> file-sync (data) .. you have to create a sink "contact" even on the file-sync right now. I guess the first step you'll fail on doing this mixup is the discovery phase, which ends up and checking for "same sinks" in the end of this phase. The second issue we had in the past with file-sync with changes as "data" from a plugin with several object types at once, was the duplicate UID problem. Imagine you have a plugin which stores contacts and events - and there is an contact entry with UID "xyz" and an event entry with the UID "xyz". Since the file-sync used to use the UID as filename there was a problem with storing those entry without losing the data. But for this case there are "duplicate" function for entries, which will change the UID of the entry with the same UID (it will append "-dup" to the UID). Since we didn't managed to handle this flawless in file-sync we decided to stay for time being with "forcing" the file-sync to use seperated directories for different objtypes/sinks. But i guess lot's of people will miss this feature. So we should try to get this working again by time. I already tried in the past to get this working again, but there are some further stuff to do to get this working flawless. #1 fix conversion path for objformat-xyz to objformat "file" * doesn't work smoothly for all objformat right now * for example for objformat which contain structs with pointers and needs to get marshalled - e.g. gnokii-format, palm-format, ... It would be nice to have a conversion path which marshal those formats with their marshal function and dump this on disk. But since the marshal function could be buggy as well this isn't safe... #2 review what the discovery phase does and make it aware of the "data" wildcard #3 fix the duplicate UID problem in file-sync, by just changing the UID to with the duplicate function best regards, Daniel ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Daniel,
So currently libopensync support five obj types: * data: a wildcard * event: * contact: * note: * todo: Is all objtypes a static list? I mean any possible to add more objtypes like file, image, email, and so on in the future. (file is wildcard for image and email) This could affect the GUI implement. Thanks, Halton.

Yeah, that is possible and intended. Just write a new format plugin which registers a objformat with a new object type. We might should specify future objtypes, to avoid different names of object type - bad example: picture, image, photo, ... PS: there is already the object format "file" with the object type "data" ;) So from your list only object type "email" and "image" is missing... Also cool would be: - "bookmark" - "account" - like keys/passwords/account (e.g. from KWallet, gnome-key-ring) ... - "email" - "image" But i guess you're asking to know if it's worth to handle the number of available object types dynamic, not static/hardcoded - right? If so you might still need to map those objtype strings to something human-readable inside your UI. Like: "contact" -> "Contacts", "event" -> "Appointments", ... best regards, Daniel ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Daniel,
Could you answer explain my question about "object type" and "object format"? We need understand it well before design our PluginManager. BTW, I'm concern about the overlap on different object types. Besides data is 'wildcard', is there any coverage for rest of them? If have, how to know the relationship? Thanks, Halton.

(New) Whitepaper: 2.3 Object Types ----------------- The term ">Object Types"< is in OpenSync used to describe the type/category of data. Example for ">Object Types"< are Contacts, Events, Todos, Notes or plain Data (like the content of a file) and others. (It’s not limited to PIM Data!). Those Object Types get separated processed, to make it configurable which Object Type should get synchronized. Example: Only synchronize contacts of the mobile, no events, todos nor notes. 2.4 Formats (( equal/similar to the term "Object Format" )) ----------------------------------------------------------- The ability to synchronize different Parties which use different formats, makes the OpenSync Framework to a very powerful Synchronization Framework. In OpenSync each Format is associated with one Object Type (see previous chapter). This Object Type as common denominator for different formats makes it possible to determine a conversion path between different formats. The conversion path consists of various format converters, which are provided by Format Plugins. Example: Two parties should synchronize their contacts (the Object Type). Party A stores the contacts as VCard 3.0 and Party B stores the contacts in some Binary Format. To synchronize the VCard 3.0 and the Random Binary Contact Format format plugins have to register those formats and provide converters. The Plugins don’t have to provide converters for every known Format, often a certain amount of converters to common formats or a common denominator format is enough to create a conversion path between VCard 3.0 to Binary Contact Format. http://cryptomilch.de/~dgollub/OpenSync/OpenSync-0.40-DRAFT-20080118.pdf Please, let me know if this helps or if you have further questions. > BTW, I'm concern about the overlap on different object types. Besides > data is 'wildcard', is there any coverage for rest of them? If have, how > to know the relationship? IIRC, there should be no overlap expect the "data" object type. All the other object types should not overlap - or do you have some object types in mind? Btw. there are also other format plugins beside the vformat one. (e.g. gnokii-format, palm-format, opie-format(?), ... even xmlformat is a format plugin ;)) best regards, Daniel ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
