+Release Notes db2triples v0.9.9
+
+Released on 08/04/2012
+
+1. New features
+
+1.1 R2RML, implementation of new W3C Candidate Recommendation of 23
+February 2012
+
+ (see http://www.w3.org/TR/r2rml/ for more information)
+ which includes among others:
+
+ * New R2RML data model
+
+ * New R2RML vocabulary
+
+ * Datatypes treatments are now normalized (in a generic SQL formalism)
+
+ * Any DBMS that conform to Core SQL 2008 can now be mapped with
+ its specific driver (tested only on PostGreSQL, which conforms
+ to at least 160 mandatory features required for full Core
+ conformance of 179)
+
+ * Support for MySQL
+
+ * Support for binary types conversion
+
+ * Support for predicate rr:inverseExpression (optimize term maps
+ processing that reference derived columns in R2RML views)
+
+ * Support for limited and regular SQL identifiers : allows to
+ execute SQL query with case-sensitive/case-insensitive SQL
+ identifier syntax rules
+
+ * Support for canonical RDF lexical forms and transformation
+
+1.2 Direct Mapping, implementation of new Candidate Recommendation of
+ 23 February 2012 (see http://www.w3.org/TR/rdb-direct-mapping/ for
+ more information) which includes among others:
+ * Support for binary types conversion
+
+ * Support for canonical RDF lexical forms and transformations (that
+ uses the same common rules as R2RML)
+
+
+2. Improvements
+
+2.1 Syntax of URI
+
+ * URI syntax of generated RDF terms strictly complies with the W3C
+ standard: IRI-safe version of string, percent-encoding and other
+ encoding process in the two Candidate Recommendations are
+ implemented.
+
+
+2.2 XMLSchema Types Management
+
+ * Rules for canonical RDF lexical forms and transformations
+
+3. Known Issues
+
+3.1 R2R2ML
+
+ * Use of litterals with bad types does not yet raise "Data error"
