'''AllegroGraph''' is a closed source [[triplestore]] which is designed to store [[Resource Description Framework|RDF]] [[Semantic triple|triples]], a standard format for [[Linked Data]].<ref>{{cite news|last1=Claburn|first1=Thomas|title=Web 2.0 Arrives to Find Web 3.0 Underway|url=http://www.drdobbs.com/web-development/web-20-arrives-to-find-web-30-underway/199001127|accessdate=22 September 2015|work=Dr. Dobb|publisher=UBM Tech|date=16 April 2007|archive-url=https://web.archive.org/web/20150904164558/http://www.drdobbs.com/web-development/web-20-arrives-to-find-web-30-underway/199001127|archive-date=4 September 2015|url-status=dead}}</ref>

It also operates as a [[Document-oriented_databaseoriented database|document store]] designed for storing, retrieving and managing document-oriented information, in [[JSON-LD]] format.

==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.<ref>[http://www.w3.org/2001/sw/DataAccess/impl-report-protocol SPARQL Protocol Implementation Report]</ref> SPARQL is a standard query language for linked data, serving the same purposes for RDF databases that [[SQL]] serves for relational databases.<ref>{{cite book|last1=R|first1=Angles|title=2012 IEEE International Conference on Data Engineering Workshops|date=2012|publisher=IEEE|___location=Piscataway|isbn=978-1-4673-1640-8}}</ref>

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 (programming language)|Java]], [[Python (programming language)|Python]], [[Common Lisp]] and other APIs.<ref>{{cite book|last1=Watson|first1=Mark|title=Scripting intelligence : Web 3.0 information gathering and processing|date=2009|publisher=Apress|___location=Berkeley, CA|isbn=9781430223511|edition=New|url-access=registration|url=https://archive.org/details/scriptingintelli00wats}}</ref>

The first version of AllegroGraph was made available at the end of 2004.<ref>{{cite book|last1=Watson|first1=Mark|title=Scripting intelligence : Web 3.0 information gathering and processing|date=2009|publisher=Apress|___location=Berkeley, CA|isbn=9781430223511|edition=New|url-access=registration|url=https://archive.org/details/scriptingintelli00wats}}</ref>

===Languages===

AllegroGraph has client interfaces for [[Java (programming language)|Java]], [[Python (programming language)|Python]], [[Ruby (programming language)|Ruby]], [[Perl]], [[C Sharp (programming language)|C#]], [[Clojure]], and [[Common Lisp]]. The product is available for Windows, Linux, and Mac OS X platforms, supporting 32 or 64 bits.<ref>{{cite web|url=https://franz.com/agraph/downloads/clients|title=AllegroGraph Client Downloads}}</ref>

For query languages, besides SPARQL, AllegroGraph also supports [[Prolog]] and [[JavaScript]].<ref>{{cite conference |url=https://www.scitepress.org/papers/2018/69102/69102.pdf |title=Graph Databases Comparison: AllegroGraph, ArangoDB, InfiniteGraph, Neo4J, and OrientDB |last1=Fernandes |first1=Diogo |last2=Bernardino |first2=Jorge |date=2018 |book-title=Proceedings of the 7th International Conference on Data Science, Technology and Applications |pages=373–380 |___location=[[Porto]] |conference=DATA 2018 |publisher=SCITEPRESS – Science and Technology Publications, Lda |isbn=978-989-758-318-6}}</ref>

AllegroGraph includes an implementation of [[Prolog]] based on the implementation developed by [[Peter Norvig]] in [[Paradigms of AI Programming: Case Studies in Common Lisp|Paradigms of Artificial Intelligence Programming]].<ref>[http://franz.com/agraph/support/documentation/v4/prolog-tutorial.html Allegro Prolog]</ref>{{primary-inline|date=September 2015}}
