Therefore researches of framework and middleware are becoming active area. However, these frameworks mainly aim to handle discrete information such as event messages, therefore they seem to insufficient for handling continuous information such as sound and movie. Then we propose a framework called EntityCollaborator, which aim to converge discrete and continuous information using SIP. EntityCollaborator neaded to hide SIP methods and session management, and to provide a lookup service for finding component in a distributed environment. Therefore, to settle these specifications, we provided event-driven APIs and lookup service by using DHT, and which led EntityCollabrator to obtain these features; cooperation function with SIP-based applications, high scalability, adhoc nature, and robustness.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1802","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1794","bibliographicIssueDates":{"bibliographicIssueDate":"2008-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"49"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"フレームワーク技術"}]},"weko_creator_id":"1"}}
