AllegroGraph is a closed source triplestore which is designed to store RDF triples, a standard format for Linked Data. [1] It also operates as a document store designed for storing, retrieving and managing document-oriented information, in JSON-LD format. AllegroGraph is currently in use in commercial projects [2] [3] [4] [5] and a US Department of Defense project. [6] It is also the storage component for the TwitLogic project [7] that is bringing the Semantic Web to Twitter data. [8]

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. [9] SPARQL is a standard query language for linked data, serving the same purposes for RDF databases that SQL serves for relational databases. [10]

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. [11]

The first version of AllegroGraph was made available at the end of 2004. [12]

Languages

AllegroGraph has client interfaces for Java, Python, Ruby, Perl, C#, Clojure, and Common Lisp. The product is available for Windows, Linux, and Mac OS X platforms, supporting 32 or 64 bits. [13]

For query languages, besides SPARQL, AllegroGraph also supports Prolog and JavaScript. [14]
