AllegroGraph is a closed source triplestore which is designed to store RDF triples, a standard format for Linked Data. AllegroGraph is currently in use in Open source projects, commercial projects〔(GenomeWeb-Pfizer Article )〕〔(Eli Lilly Project Presentation )〕〔(Making a Semantic Web Business Case at Pfizer )〕 and Department of Defense projects.〔(Contributions to a Semantically Based Intelligence Analysis Enterprise Workflow System )〕 It is also the storage component for the TwitLogic project〔(TwitLogic Paper )〕 that is bringing the Semantic Web to Twitter data. ==Implementation== AllegroGraph was developed to meet W3C standards for the Resource Description Framework, so it is properly considered an RDF Database. It is a reference implementation for the SPARQL protocol.〔(SPARQL Protocol Implementation Report )〕 SPARQL is a standard query language for linked data, serving the same purposes for RDF databases that SQL serves for relational databases. Franz, Inc. is the developer of AllegroGraph. It also develops Allegro Common Lisp, an implementation of Common Lisp, a dialect of Lisp (programming language). The functionality of AllegroGraph is made available through Java, Python, Common Lisp and other APIs. The first version of AllegroGraph was made available at the end of 2004. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AllegroGraph」の詳細全文を読む スポンサード リンク
