Recently a number of LOD-sites has increased with reflecting latest research and development activities. But it still seems that not only RDF and OWL researchers but also more system developers should be able to participate in those activities for realizing final goals of Linked Open Data. In order to make the system development work less cost, we propose a web API family for JavaScript programming, which encapsulates the SPARQL endpoint system and a back-end RDF store. By using this system, we think more people having different domain data can enroll RDF data more easily and freely, and view the data via various application programs. The report includes the functions on Class, Property management and deletion of RDF instances.

A Rakugoka is a storyteller who performs Rakugo which is a Japanese traditional performing arts. A Rakugoka succeeds a Myoseki which is a prestigious professional name from generation to generation. In this paper, we propose a model for describing metadata about Rakugoka and Myoseki.

For biomimetics research, it is important to develop biomimetics database which enable us to find a huge variety of knowledge across different domains. To realize such database, an interoperability of knowledge between them is necessary. Ontologies clarify concepts that appear in the target domains and contribute to improvement of interoperability. This article discusses roles of ontologies in a biomimetics database thorough some experiment in other domains.

SOCIA (Social Opinions and Concerns for Ideal Argumentation) is an LOD data set for citizen participation, which contains background information about regional social issues. We aim to apply it to promoting recovery from disasters, e.g., recovery from Great East Japan Earthquake. To develop services for the recovery, we introduce some classes and properties for representing stakeholders' goals and decisions. The expansion enables us to develop services for matching citizens' goals and for sharing and evidence of decision making.

This paper aims at showing the design process of the Sustainability Science Ontology to support the use of Linked Open Data in the context of problem-solving. Especially, we focus on systematizing the countermeasure concepts, we trace its design process based on ontological approach..

Japanese Wikipedia Ontology (JWO), which we have constructed semi-automatically from Japanese Wikipedia, has problems with a lack of upper classes, and appropriate definitions of class-instance relationships and properties. The purpose of our research is to complement the upper classes in JWO by integrating JWO and Japanese WordNet (JWN). In order to accomplish this, we develop tools which support the user to refine the class-instance relationships, to identify JWO classes to be aligned with JWN synsets, and to align the JWO classes with the JWN synsets through user interaction. In addition, we integrate JWO and JWN by using a domain ontology development environment, DODDLE-OWL.
