I’m sure this isn’t easy pickin’s, but it would be nice to have customizable metadata fields. The program that currently does this best, from my experience, is Tinderbox. You can define just about any type of metadata field you’d like: one field for (submitted/not submitted), one for (published/unpublished), one for (reviewer:), etc.
So why don’t I just use TB? Because it’s not intended as a filing system, as a front-end library to the Finder. It can’t take and search through PDFs or many other types of files. You can import pictures, but in so far as they are places within a text file, so that you have a text file with a picture in it as a result. This doesn’t diminish its brilliance – its wonderful for a myriad of other usages – but its not meant to file things.
There is a shareware program out there called Spotmeta, which allows one to add any type of custom metadata fields to your documents and files. After doing this, you can then use spotlight to search for them. The problem there, however, is that spotlight cannot easily be used to specify what folder to look in, i.e. to ONLY look through that field of metadata that you’ve created (i.e. only look in my “reviewer” field.) The Finder’s search (as opposed to spotlight) can kind of do that, but its boolean operations are way too limited to be of much use (i.e. you can tell it to look in your custom made fields – it does recognize them – but its virtually useless when you want to, say, find all files that have “Reviewer = John” OR “Modified = Yesterday” but NOT html documents. (There is a shareware program called Meta which can search through them, but you have to type in the looooong strings of your custom fields; and another called MoRU, but its boolean is also limited).
I think this is a feature that would put EagleFiler far above the competition. Either (a) built in metadata field additions + the ability to search through them from within EF, or (b) at least a way for EF to also be able to run its boolean searches on metadata placed by spotmeta or other such programs in the file’s metadata section.
As such, EF would become at once a brilliant database, filing scheme, and – to some degree (without going overboard) – a solid replacement to the weaker features of the Finder and spotlight.
