rdfa-core-java is Java implementation of RDFa Core 1.1 standard.
rdfa-core-java includes XHTML+RDFa 1.1 host language support and supports both SAX and DOM parsing. Project is a part of a closed world assumption based message validation service created under Finnish government funded Tikesos-project.
Unlike other parsers, rdfa-core-java stores location information for rdfa attributes (Line and Column numbers in SAX, Nodes in DOM). This information is used by the validation service to provide user informative messages (such as cardinality failures, undefined data types, invalid data types, unexpected properties, etc.) about document structure.
Jena integration example is provided as a unit test.
