Are those official names or just written in Semithic way?
Yes kinda
Profile 0 : Codestream restrcitions named 'profile 0'
Profile 1 : Differente Codestream restrcitions named 'profile 1'
Profile2 : No codestream restrictions
see ISO 15444*1 section A.10:
In order to promote the wide inter-operability of JPEG 2000 codestream,
codestream restrictions are introduced. "Codestream Restrictions" have
two profiles, Profile-0 and Profile-1. The case of "No Restrictions"
meaning conforming to this Recommendation | International Standard can
be called Profile-2. Profile-0 and Profile-1 are defined as follows.
Maximum interchange will be achieved for codestreams corresponding to
Profile-0, and medium interchange for codestreams corresponding to
Profile-1.
