However, in Taiwan, most open datasets are still separated and linked open data (LOD) is still lacking. Without LOD, application developers are hard to locate appropriate open datasets and combine multiple open datasets to create innovative applications. Therefore, to address the above issue and to further facilitate the consumption and the spreading of open data in Taiwan, we propose a data query language, referred to as LODQL (Linked Open Data Query Language), to allow the creation of rules for building LOD by data experts, and design the LODE (LODQL Engine) to parse the LODQL, build LOD in RDF (Resource Description Framework), and generate the corresponding RESTful services that produce required LOD based on the user query. LODE is also able to perform data visualization to show relevance of open datasets and relationships among open data items. System prototype and evaluation experiments show that the feasibility and effectiveness of LODQL and LODE.
