    Simple Pojo/Bean Mapper

    An ANT task to generate the conversion classes to allow you to create

    The original use for this was to take data out of a set of Hibernate DAO objects and create a variety of XML DOM objects from them. In the project that instigated this work the mapping between the DAOs and the XML DOM was not one for one and encoding the conversion into the DOAs was not a good idea. While at first sight this may seem similar to dozer (http://dozer.sourceforge.net) the primary difference is that this is code generation and does not have the overhead of using introspection at run time.

    SmartSlog (Smart Space Ontology) is a software/application development kit (SDK or ADK) for programming Smart-M3 agents (Knowledge Processors, KPs) that consume/produce smart space content according with its high-level ontological representation. SmartSlog applies the code generation approach: given an OWL ontology description, the ontology programming library is produced. The latter provides API to access the smart space via a Smart-M3 Semantic Information Broker (SIB) and data structures and functions to represent and maintain locally in KP code all ontology classes, relations, properties, and individuals. Since 2012 the project is supported by grant KA179 of Karelia ENPI programme, http://kareliaenpi.eu/ More information about project: http://oss.fruct.org/wiki/SmartSlog Smart-M3 on Wikipedia: http://en.wikipedia.org/wiki/Smart-M3
