More than a CMS: structr is a content application framework based on the graph database Neo4j.
Version 0.4.M01 is available at Github.
It occurs to me that a content creation interface could offer a query on properties feature enable node discovery. Or that could be automatic. Such that when I type “structr” that post is added as an occurrence to the topic for structr. End of post the interface offers me the opportunity to say what is correct/incorrect.
