Re: Extended attributes lastCrawlAttr

In my opinion, the use of Extended Attributes is a bad design choice.

Not all file systems support extended attributes. More importantly, it
means that you cannot index read-only devices, filesystems or
directories.

The correct design, in my opinion, is to hold the data that is currently
written to the EAs inside Beagle's indices. This not only allows for
read-only data sources, it also provides some of the infrastructure for
time based queries (what files was I working with at this date?).
