Thanks! Speaking about reading documentation, there is two sources that
I found valuable:
For the model behind following packages:
* org.opengis.metadata
* org.apache.sis.metadata.iso
I recommend the NOAA wiki:
https://geo-ide.noaa.gov/wiki/index.php?title=Category:ISO_19115
I found it useful because the ISO standard just gives a succinct
description of each element. It is sometime hard to guess how we are
supposed to use them. The NOAA wiki explains in more details: the
purpose, best practice, etc.
For the model behind following packages:
* org.opengis.referencing
* org.apache.sis.referencing
I recommend OGC topic 2, "Spatial referencing by coordinates", in
particular annex B, "Context for modelling of spatial referencing by
coordinates" and annex C, "Geodetic concepts":
http://portal.opengeospatial.org/files/?artifact_id=39049
Those two annexes help to understand why Coordinate Reference System
classes are designed that way, why apparently simple solutions like
using WGS 84 as a universal pivot does not work, etc.
