Abstract: Extensive collections of Chinese ceramic vases are housed in museums throughout China. They could serve as rich sources of data for historical research. Although some data sources have been digitized, the vision of heritage institutions is not only to display objects and simple descriptions (drawn from metadata) but also to allow for understanding relationships between objects (created by semantically interrelated metadata). The key to achieving this goal is to utilize the technologies of the Semantic Web, whose core is Ontology. The focus of this paper is to describe the construction of the TAO CI (“ceramics” in Chinese) ontology of the domain of ceramic vases of the Ming (1368-1644) and Qing (1644-1911) dynasties. The theoretical and methodological approach adopted to construct the TAO CI ontology is term-and-characteristic guided, i.e., it relies on a morphological analysis of the Chinese terms used in the domain, and respects the ISO principles on Terminology (ISO 1087 and 704), according to which concepts are defined by means of essential characteristics. The research presented in this article aims to publish the resulting structured data on the Semantic Web for the use of anybody interested, including museums hosting collections of these vessels, and to enrich existing methodologies on domain ontology building. To our knowledge, there are no comprehensive ontologies for Chinese ceramic vases. TAO CI ontology remedies this gap and provides a reference for ontology building in other domains of Chinese cultural heritage. The tool used is Protégé. The TAO CI ontology is open access here: http://www.dh.ketrc.com/otcontainer/data/OTContainer.owl. 1 INTRODUCTION data through an open data policy. To bridge this gap, this paper proposes the TAO CI ("ceramics" in China has a rich cultural heritage and has Chinese) ontology. In compliance to the ethos of concentrated on producing digital data under the first reuse recommended by the W3C, the TAO CI wave of digitization. This is also true of the ontology relates to existing ontologies and thesauri, knowledge domain of Chinese ceramic vessels. The such as CIDOC CRM (Cidoc, 2003), EDM (Doerr et domain of Chinese ceramic vessels is rich, yet it lacks al., 2010), and AAT (Soergel, 1995). First, the TAO knowledge representation models (ontologies) to CI ontology aims to provide an important reference capture Chinese pottery concepts, express them in for the publication of other cultural heritage Semantic Web compatible interchange formats, and ontologies and to be conducive to more and more make them shareable and linkable to other data. As Chinese heritage institutions publishing open cultural there is no ontology in the domain of Chinese heritage data and linking them. Second, the ceramics providing the semantics of relevant data, theoretical and methodological approach adopted in most heritage institutions in China have not yet the construction of the TAO CI ontology is term-and- published cultural heritage data on the Semantic Web. characteristic guided, i.e. it adopts the ISO principles Furthermore, every institution accumulates its data in on Terminology (ISO 1087 and 704), which define its own traditional database system rather than linking concepts on the basis of their essential characteristics for defining concepts.

The rest of the paper is organized as follows: 2.2 Collection of Vases Section 2 describes the domain, section 3 introduces the objectives, section 4 is dedicated to the state of the The first step of our work was to select the set of vases art. Section 5 is the main section dedicated to our to study. The set had to be enough representative of contribution to ontology building methodology the richness of the domain without being too big since relying on a morphological analysis of Chinese terms the main and first goal was defining the ontology and on the ISO principles on Terminology.

Four objects come from the Shanghai Museum 10 and two objects from the Capital Museum 11 . For the selection of objects, we have Chinese history goes back about 5,000 years. Chinese adopted the following three criteria. The two first ceramic vessels are among the most iconic objects of concern the selection of the museum, which had to Chinese cultural heritage. Changes in pottery styles fulfil the following conditions: first, the collection of reflect the change in dynasties.
