1. As a standalone server that supports Lisp, Ruby, Java, Clojure, Scala, Common
Lisp, and Python clients. A free version (limited to 50 million RDF triples - a
large limit) that can be used for any purpose, including commercial use.
2. The WebView interface for exploring, querying, and managing AllegroGraph
triple stores. WebView is standalone because it contains an embedded Allegro-
Graph server.
3. The Gruff for exploring, querying, and managing AllegroGraph triple stores
using table and graph views. Gruff is standalone because it contains an embed-
ded AllegroGraph server.
4. A library that is used embedded in Franz Common Lisp applications. A free
version is available (with some limitations) for non-commercial use.
This book uses AllegroGraph in embedded mode because this is the most agile way to
experiment and learn the APIs. What you learn in this book is applicable to all of the
AllegroGraph products. Currently, the server release is version 4.0 and the embedded
library release is 3.3.
