DataGuides and shape have been proposed to represent the structure of semistructured data. As these can behave as schema in the point of view of representing the structure of data, and are changed according to the existence of objects, these are called dynamic schema in this paper. This paper proposes the semi-dynamic construction method of the dynamic schema. The proposed method uses versions of the dynamic schema. Several versions are kept in the system. Each version of the dynamic schema keeps the objects required to construct its next version from it in a list. The correct dynamic schema can easily be constructed by using the versions of dynamic schema and the lists of objects. The performances in deriving the shape, and inserting and deleting objects are experimentally evaluated. Experimental results show that the proposed method is effective in the case that the deletion is occurred only on the recent objects.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"40","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告情報学基礎(FI)"}],"bibliographicPageStart":"33","bibliographicIssueDates":{"bibliographicIssueDate":"1999-05-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"39(1999-FI-054)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"updated":"2025-01-19T23:01:08.673745+00:00","created":"2025-01-18T23:07:39.225959+00:00","links":{}}
