You just seem reluctant to the idea for no good reasons (IMHO). That you can't see the files when you are offline is not a fact, but completely in your mind, it can be solved simply with local caching. It's an implementation detail and any network file system needs to deal with being offline anyway (queue local changes, synchronize). That's the whole point of putting the functionality into the FS - making this transparent to applications. As for moving other types of files into the people folder - why can't the FS reject that and return a meaningful error? Now, whether or not you consider it a serious drawback is a question. I think nothing prevents you from not using the feature, simply store real Person files elsewhere, along with any other type of file you wish. The People file system is still a neat idea, since it solves a serious problem. One that is way more annoying and confusing than not being able to store any type of file in the people folder.Lack of transparency on how things work would be the main argument. The people folder was there for a long time as an usual folder, and suddenly with this it becomes something stored on the internet, somewhere. It can still be accessible with local caching, so the fact that it's an internet folder is hidden. I see different problems : * This file system is not able to store actual files, so to me it sounds like an abuse of an existing API. It solves the problem, yes, but it's a hack, not a clean and beautiful solution. Maybe it's just a matter of renaming "file system" :) * The impossibility to store regular files in this folder can be solved with a meaningful error message. But what about moving person file from this FS to outside of it ? users may find their jabber contact list emptied by just trying to clean up their home directory. (and same for emails, moving them out of the IMAP-FS has the unwanted side effect of deleting them from the server) * The reverse way, some sensitive info may end up exposed to everyone on the internet by not knowing that this folder is actually not local to the computer. This is a security concern. I don't say it's completely a bad idea, all of this can likely be solved in some way or another, but it needs careful thinking. All of this alsosounds like a move to cloud computing, which I don't think I like much. The local computer becomes, as you say, a cache for remote data. I want my computer to be the primary storage, and the remote server to be a mean of sharing the data to other computers. On the technical side this may end up being the same, but it's conceptually very different. Also, does it make sense from a programmer point of view ? A dedicated People API would allow apps to easily query for person on various attributes. I don't think it makes sense to use the file API for this, even if it features the right functions. So, on the technical side I agree it's fine, but I think t's confusing for the end user, and that will create problems because users will do wrong things. The UI may be special-cased around it with error/warning messages, special icons, and all, but then, what's the point of using Tracker if it works all different in the end ?
Several points maybe:* You are right that there are some issues created that need careful thinking and good solutions.
* IMHO the simplicity and transparency of BeOS/Haiku has been misused too often recently to try and stop certain new features from being implemented certain ways or being implemented at all. It's an argument that I look at very carefully before accepting it applies in a given situation. After all, each of us knows awfully little about how computers work at various levels. That's perfectly ok, don't get me wrong. When we *perceive* we know how one thing works, we can't always argue it becomes more difficult or is not simple anymore when a new concept is embraced in that thing.
* The whole cloud thing wouldn't be an issue if people were not facing the fact that they need to keep data synchronized transparently over several of their own devices, or that some data is stored completely elsewhere entirely. Trying to provide a solution for these challenges is not a bad thing. It should not be shut out because it makes a computer less transparent. The FS idea is a solution which enforces consistency and avoids several points of failure that other solutions may have. Thus it has the potential of making the live of users easier. You are correct that it creates some issues of its own that need careful solutions.
