miniblocks--benja states that the default MIME type of a miniblock is text/plain. Since we are promoting Unicode, this should be text/plain;charset=UTF-8.
Another issue with miniblocks--benja is that it is based on the data: URI scheme, but doesn't follow it too closely. Should we change this at the same time?
RESOLVED: Yes, because we're about to implement miniblocks--benja and it is still time to change this, while later we'd have compatibility issues. Being consistent with other specifications is always a Good Thing :-)
In addition, to be closer to RFC 2397 (The "data" URL scheme), the syntax is modified to the following:
where <random> is a base64-encoded string containing at least 160 bits of randomness (as in urn-5), <counter> is a counter of miniblocks with the same <random> part (only [0-9] digits are allowed), <mimetype> is the content type of the block, with optional parameters, and <data> is the actual data.
We will not support base64 encoding in Gzz initially (just as we don't support anything but text/plain;charset=UTF-8).
The case of 'data' and ';base64' does not matter (as well as the case of 'storm' doesn't, per the URI spec).
