GRDDL is a technique for using XML/XHTML dialects (especially microformats) as custom RDF syntaxes by having each document point, directly or indirectly, to a transformation to an RDF graph. RDFa is a design for mixing RDF syntax into HTML. GRDDL accomodates a wider variety of dialects at the expense of asking consumers to execute potentially untrusted code. RDFa allows one parser to work for data from a variety of domains and provides a direct relationship between the RDF data and the HTML document structure, which provides better support for copy-and-paste.

Text2Onto

http://ontoware.org/projects/text2onto/

Text2Onto is a framework for ontology learning from textual resources that extends and re-engineers an earlier framework developed by the same group (TextToOnto). Text2Onto offers three main features: it represents the learned knowledge at a metalevel by instantiating the modelling primitives of a Probabilistic Ontology Model (POM), thus remaining independent from a specific target language while allowing the translation of the instantiated primitives into knowledge representation mechanisms such as RDFS, OWL, and F-Logic
