> There is currently no public API for getting the {{javax.sql.DataSource}} instance for
Apache SIS {{SpatialMetadata}} database. There is {{Initializer.getDataSource()}} method in
the {{org.apache.sis.internal.metadata.sql}} but this is non-public API, subject to change
in any future SIS version and will not be accessible in Java 9 (unless the restriction is
bypassed by Java options on the command-line).
> A standard way to provide {{DataSource}} in Java is with _Java Naming and Directory Interface_
(JNDI). However there is no JNDI environment by default in standard Java installation; JNDI
are rather provided by containers like Tomcat. We could provide our own micro-JNDI when no
environment is installed, but it may be disruptive as installing our own JNDI environment
would have a JVM-wide impact.
> A last-resort approach would be a {{public static DataSource getXXX()}} method somewhere,
but it would not follow standard mechanisms (JNDI, dependency injection, _etc._).
