Symbols aren't symbols if they don't mean anything, right?

Assuming that this rubbish actually means something, we have a lot of symbols here:

Since the last project log I've colored the individual symbols. Same color means same symbol - but wait, they can be rotated, color-inverted but not mirrored. They also do have a border, which could be interpreted as some kind of sign.

The findings until now:

• each symbol has a 1px frame/border which can be white or black, referred to as "sign" from now on
• the whole image has a black frame/border of 1px
• the map contains (only) 7 unique symbols
• these 7 symbols show themselves in 40 unique variations of symbol, sign and rotation

If you hate colors, here's a text version with even more information:

• the sign ("-" or " ") tells you if the symbol is inverted or not (i.e. a "-" means that the border is black, otherwise the frame is white)
• the number in front of the bracket is just an identifier for the symbol in the range of [0-6], since there are only 7 symbols
• the number in brackets tells you the rotation of the symbol, it multiplies by 90° (so 0=0°, 1=90°, 2=180°, 3=270°), the reference for the rotation is the rotation of the orientation the symbol had when it first showed up in the map.

So, while IMHO this is definitely a code, I have no idea what it means yet. In the chronological order of how the hints are presented, my guess is that this can be decrypted by using the next hint. This time, it's a dead link image file:

Of course, we can only hope, that this dead link is intentionally dead. Actually, it's also not really dead, it links us to this filehoster page, where we can dowload an empty txt file named "0dfz7.txt".

I'm not getting a clue from this, so for now, that's it. Any ideas?
