Hi Jonathan, Import / Export needs revamped. I am working on SPML (SignPuddle Markup Language) which will cover all of the information available in SignPuddle. Perhaps you can review and comment when I have it ready. SignMail... Needs an update. I may add it to SWIS. BSW will be the standard for SignWriting data. SPML will use BSW hex data rather than BSWML or the build string. Implementing BSW shouldn't be too hard. SWIS contains 2 separate working implementations; one in PHP and another in JavaScript. As long as you can understand regular expressions, it should be relatively easy. Keep up the good work on the Studio. Sorry to force updates with the standards. The ISWA 2010 is really worth it and it will be stable for a long time to come. BSW is really superior to the other formats and it is UTF-8 compatible. Here's a truncated BSW primer... Each character of BSW can be represented by a single ASCII token: # B = SignBox Marker # L = Left Lane SignBox Marker # R = Right Lane SignBox Marker # h = Hand Symbol # m = Movement Symbol # d = Dynamic Symbol # 1 = Head Symbol # 2 = Trunk Symbol # 3 = Limb Symbol # n = Number Character # Q = Sequence Marker # s = Sequence Symbol # P = Punctuation Symbol An entire sign text can be validated with a single regular expression: ([LBR]([hmd123]nn)*(Q[hmd123s]+)?|P)+ We can even evaluate a SignSpelling Sequence to determine if it is regular. Q[h*(md)*]+[123s]* A regular SignSpelling Sequence is espoused by Val as described in the SignSpelling Guidelines PDF. A regular SignSpelling Sequence places all of the location markers after the hands and movement. Charles advocates an irregular spelling where location is mixed with the hand shapes. Time will tell which is better, but we have a simple check to determine if it is regular or irregular. Regards, -Steve
