Furthermore, the Java-based RP language SignalJ provides persistent signals, where the update history of a signal is considered time-series data, and the value of the signal is considered as a function of a specified (possibly past) time. SignalJ have been targeting to local systems; however, the entity of a persistent signal exists in the time-series database, which exists in the outside of the language and can be a basis of open reactive systems. In this paper, we propose an implementation of infrastructure system for open and distributed persistent signals by utilizing such a characteristic. We also discuss several issues on realizing software development based on this infrastructure.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ソフトウェア工学（SE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-03-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2022-SE-210"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217293,"links":{}}
