On the Study of Information Model for Literary Data Unification

从异构信息系统中同时检索数据的通用数据模型的研究一直在继续。都柏林核心元数据和TEI （Text Encoding Initiative）标头作为通用数据模型进行了研究。此外，作为一种新的元数据方案，基于时空数据模型的ECAI （Electronic Cultural Atlas Initiative）元数据被引入并进行了研究。特定于区域的数据模型和转换规则引入了特定于区域的数据模型，将每个数据库中的每个数据项映射到Dublin Core元数据中的适当项。从每个数据库到Dunlin Core元数据的直接数据映射是可能的。但是，Dublin Core元数据不能满足专家的需求，因为Dublin Core元数据中的数据项很少。因此，每个专家的数据映射不同，导致数据质量不高。引入特定于区域的数据模型作为数据转换的媒介。我们采用TEI Header作为文本数据转换，日本MARC作为目录数据，ISAD(G)作为档案。我们还定义了从每个数据库到每个区域特定数据模型的映射规则，以及从每个区域特定数据模型到Dublin Core元数据的映射规则。数据创建使用上述数据模型，已经检查了数据转换。审核使用馆藏资料目录数据、OAPC数据、全文数据、图像数据、档案数据。转换程序已经作为科研资助(B)的一部分进行了。@由于我们刚刚完成了转换数据，因此将在2002年的研究中进行评估，也作为科研资助(B)的一部分。@我们还研究了时空数据检索的有效性。我们将部分档案数据转换为ECAI兼容格式，并尝试使用ECAI提供的AECAI Time Map @检索和显示时空数据。

DataModel A study on general purpose data model to retrieve data simultaneouly from heterogeneous information system has continued. Dublin Core meta data and TEI (Text Encoding Initiative) Header have studied as the general purpose data model. Furthermore, as a new meta data scheme, ECAI (Electronic Cultural Atlas Initiative) meta data that is based on gio-temporal data model has been introduced and studied. Region-Specific Data Morel and Conversion Rules Region-specific data models have been introduced to map each data item in each database into the appropriate item in Dublin Core meta data. Direct data mapping from each database to Dunlin Core meta data is possible. However, Dublin Core meta data does not satisfy experts= needs, because data items in Dublin Core meta data are a few. As the result, data mappings are different from each expert, whichresults in the low quality of data. Region-specific data models are introduced as the medium of data conversion. We adopt TEI Header as text data conversion, Japan MARC as catalog data, and ISAD(G) as archives. We also define mapping rules from each database to each region specific data model, and mapping rules from each region specific data model to Dublin Core meta data. Data Creation Using above data models, data conversion has been examined. catalog data of holding materials, OAPC, full text data, image data, and archival data are used for the examination. Conversion programs have been made as a part of AResearch-in-Aid for Scientific Research (B). @ As we have just finished convert data, the evaluation will be done in 2002 researches, also as a part of AResearch-in-Aid for Scientific Research (B). @ We also studied the validity of gio-temporal data retrieval. We converted a part of archival data into ECAI compatible format, and try to retrieve data using AECAI Time Map @ that is offered by ECAI to retrieve and display gio-temporal data.
