This time pretty picture contains only parts of the ontology I've been
actively changin since it just takes too much time to make nice layouts :)
While ontology is still not complete, it's structure is unlikely to change
much. It's quite hard to get it absolutely right in theory...
So my proposal is to start implementing it. Whatever inconsistencies, missing
fields, ambiguity or other problems we encounter will be resolved in the
process. This way, by the time xesam 1.0 spec is ready, so are actual
I'm available to answer your questions most of the time.

Also, I'm still awaiting for clarification from Tracker on what categories you
assign to files. If you want me to consider compatibility with your approach,
at least I need to know what you want/need.
Many containers support naming of contents. Fx email attachments have names.
Some kinds of content can have a global name like "file://something", but only
some. Also the trouble here is that
while a zip file is addressed like "file://x.zip" its contents might be
addressed like "zip://x.zip/document.odf"
The only sensible way out of this seems to introduce both name property for
container-local name(corresponds to file name) and url property for global
addressing if it's possible at all.
Should we have file extension field?
Should we index folders just like other files?
Implemented support for multiple filesystems, removable media indexing, disk
images in files.
This is accomplished by introducing FileSystem content type, which represent a
For disk images, the Source of the filesystem is set to File.
For hdd partitions and removable media, Partition source is used. It lets
specify both device and uuid(e.g. to identify different usb sticks).
* Content.contains is now a subproperty of Content.depends
* Added Project class
* Renamed ToDo to Task
* Added Partition source with fields
* Added FileSystem content class with fields
* Removed User class and moved properties to Source
* Added isEncrypted property to DataObject
* Revamped media ontology
