Justine, in order to get really full control over how you are using the algos, would you be able to write a simple plugin that can handle this in Java, along the lines of http://docs.neo4j.org/chunked/snapshot/server-plugins.html ?
Otherwise, you can use any scripting language and send script code to a plugin. We are right now doing a very simple one in order to execute Gremlin (or any Groovy code) through the REST API, see https://github.com/peterneubauer/neo4j-gremlin-plugin/blob/master/src/main/java/org/neo4j/server/plugin/gremlin/GremlinPlugin.java for a very early draft. Would a Java plugin work for you to start with? In there, you can use the full API, like in http://components.neo4j.org/neo4j-graph-algo/stable/ Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com/peterneubauer http://www.neo4j.org - Your high performance graph database. http://startupbootcamp.org/ - Öresund - Innovation happens HERE. http://www.thoughtmade.com - Scandinavia's coolest Bring-a-Thing party.
