Abstract
Due to the virtue of resource mapping at a hierarchic level and graph-based representation, RDF data shows promising for data reuse and federation on the Web where both documents and data are linked. There are numerous tools or frameworks used by the Linked Data community, a comprehensive survey, focusing on their objectives, methodologies and most distinctive characteristics, is given in this presentation to gain an overall view of current research trends. Furthermore, Agricultural Information Institution of the Chinese Academy of Agricultural Science (CAAS AII) has provided a new approach to RDF generation and management in an ETL (Extract-Transform-Load) environment, this presentation will share the plugin developed based on open-source Kettle, which can support RDF schema dynamic mapping and triples transformation for a wide variety of data sources, i.e., the shift from internal or open data in relational databases or files containing structured data such as Excel, CSV, XML and JSON files to RDF data.
