Implement rr:termType mapping attribute.
Remove license text from DTD.
Minor fix.
Merge branch 'feature/termType' into develop
Initial implementation for supporting R2RML syntax.
Change the input for the parser to be InputStream instead of Reader.
Make IMetaModel as a mandatory input interface to use the
BaseMappingHandler.
Bug fix missing break in the switch-case statement.
Bug fix missing subject map value in the property mapping.
Make a conditional statement, i.e., if the mapping has no class URI
definition then do not create the ClassMapping.
Fix null pointer exception because of the missing value assignment.
Fix the out of bound index exception, the index for the matcher should
be 1 instead of 2. I also fix the template string replace to use the
curly braces to ensure the string replacement to be perfectly correct.
Register the new R2RML parser to Semantika system.
Add the missing license text in the code header.
Move classes from *.mapping.sql to *.mapping.base.sql
The implementation for SqlParser is simplified by adding one more method
interface that requires IDatabaseMetadata. This action removes the
unnecessary abstract class (i.e., SqlMappingParser).
Move classes from package *.mapping.base.sql.parser to
*.database.sql.parser
Remove the unnecessary classes from the SQL parser API.
Update the mapping parser framework.
Rename class.
