The sis-build-helper module is about complete for now (more stuff will
be added later), and is summarized there:
https://builds.apache.org/job/sis-trunk/site/sis-build-helper/index.html
The sis-utility module got a few classes, mostly static methods. Some of
those methods may overlap with dedicated libraries, but nevertheless
defined in a spatial project because sometime tuned with heuristic
rules. An example of quite heuristic methods (citing ISO-19115 and
NetCDF use cases) is:
https://builds.apache.org/job/sis-trunk/site/apidocs/org/apache/sis/util/CharSequences.html#camelCaseToSentence%28java.lang.CharSequence%29
There is also tuning burned in the implementation details, for example
trimming whitespaces using Character.isWhitespace(int) rather than
invoking String.trim() in order to preserve X.364 sequences (more on it
later), making sure that we use code point API (some new geographic
Unicode symbols are defined outside BMP), etc. So having our own static
methods help us to ensure that they meet SIS needs.
