---------------------------------------

             Summary: Need a public way to get connection to "SpatialMetadata" database
                 Key: SIS-395
                 URL: https://issues.apache.org/jira/browse/SIS-395
             Project: Spatial Information Systems
          Issue Type: Improvement
          Components: Metadata, Referencing
    Affects Versions: 0.8, 0.7, 0.6, 0.5
            Reporter: Martin Desruisseaux
             Fix For: 1.0


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.
