Hi, Glad you made so much progress, well done.
You just want to set the attribute to a string value? Just use normal double quotes. > MATCH (a)-[:`is member of`|`heads`]->(b) > WHERE (b.name="Interim Transitional National Council (NTC)") or (b.name="NTC > Executive Board") > SET a.revolution_attitude = "for" The Cypher Reference Card might come handy for you: http://neo4j.org/resources/cypher Cheers Michael Am 16.03.2014 um 18:14 schrieb Jean-Baptiste Gllpn <jbgallo...@gmail.com>: > Dear all, > > a quick update on my project and a question.
