I'm building a little test app as a way to learn Angular and refresh myself
on a lot of the Spring stack. I have some minor experience with Neo4J, but
the app idea has ground with a graph db like Neo4j.
The idea is pretty simple, a ui to create characters and stories, and
relate the characters to the stories and each other, map their individual
versions of a story and create some graphs that show the character
interactions to help write the overall narrative.
I've got nodes for the characters and stories easily enough and the Spring
stack is great for giving me rest easy to use rest endpoints for the nodes
themselves. But I can't find any concrete examples of creating and
maintaining the relationships between those nodes.
For instance, in Cypher, I can relate a character to a story and tell that
being's involvement to the story as a relationship property with:
match(p:Being ),(s:Story ) where id(p) = 7 and id(s) = 16
create (p)-[r:TOOK_PART_IN{perspective:"I did not know Mr. Grey better than
an acquaintance, though I knew others whom did.
They were not made better because of their relationship with him."}]->(s)
return r
Then with the mapping in Spring, the data I get back from the REST endpoint
gives me my character and I can follow a link to get the stories that
character is a part of. I don't see a way though to post or put to add or
remove the character from stories.
I'm also only finding concrete examples in docs from Spring regarding
nodes, not really with edges/relationships. Can anyone supply anything
like that?
I am fully aware that Neo4J has it's own REST interface, and that is
basically what Spring is consuming as well. The main purpose of this
exercise is learning some new technology (Angular2/typescript) and
refreshing my knowledge of the Spring stack, I'll be hunting through the
Spring groups as well, but thought the Neo4j group may be able to shed some
light on this.
Thanks!
