BeOS & Derivatives Two news items about alternative operating system news in a row? What is this, Christmas? In any case, the Haiku project, the darling of OSNews (hey it's okay now), has released its second alpha release. This new stable development release contains some serious improvements over the first alpha.

Is this used in order to improve search ? What do I use this feature for ? Which kind of task does it help ?

In a nutshell, individual filetypes in Haiku are roughly analogous to database tables - and each filetype can be given attributes (roughly analogous to fields in a DB). Then the Tracker (filemanager) lets you display those attributes as columns so you can easily view, edit, or sort by attributes.

The three best-known examples of practical uses are managing contact/address book data, EMail messages, and audio files. So, for example, the filemanager can display columns like track number, artist, title, year, etc for audio files - essentially giving you iTunes-esque functionality, except at the OS level.

So, yes, it does help with search - but there's quite a bit more to it as well. Attributes, queries, etc, are as a fundamental to the way Haiku works as piping and redirection are to the UNIX shell - and, in fact, they're used for many of the same purposes (allowing applications to be small and focused, while still being able to share data & communicate via standardized means).
