Well, the meta structure is really just a helper for keeping data according to a certain structure... if you make those checks against it yourself, that is. There's nothing automatic in validation or insertion by using this framework as of yet.
Inserting data is still done by using the neo4j API... NeoService#createNode(), Node#setProperty( String, Object ) a.s.o. See http://wiki.neo4j.org/ for more info there. 2009/8/4 Jerry Juanico <jtjuan...@gmail.com>: > Oh I see, > Maybe I have to refresh again. > Anyway, just another question. > For example I already have configured the meta structure, with all the data > type( string, integer...), data range, etc. > Can you give an idea on how can I use or put values in it? > I'm lost here.
