Hi Phil,
It's the query that never ends...!
I looked over your schema and data, and maybe I misunderstood you or came
up with my own interpretation, but in my mind each tag was its own instance
'owned' by a particular person.
I would expect that a person could create his own custom tags from m
I'm glad it could work for you.
And yes, it is absolutely possible to add link property on the edge (we do
that without any problem).
With best regards,

Hi Colin,
I've put together a quick test of this and it does indeed return Bob even
if he did not apply the Red tag to Resource1.
Attached are 2 files:
1) I run test_db_schema.sql as an argument to the console.sh script to
create the database and schema.
2) I then start the console, connect to t
No, because the inner most select specifies "Resource1" as a starting point.

Thanks Ata, yes that would work if it's possible to add a link property to
an edge.

With the data in my diagram would this not also return Bob if he applied
the red tag only to Resource2 and not Resource1 ?
He tagged Resource1 only with blue.

Hi Phil,
I may just be missing something, but here's a simple example of what I'm
thinking.
select from (select expand(in("AppliedTag")) from (select
expand(out("HasTag")) from Resource where Id="Resource1") where Id="Red")
where Name = "Bob"
This will return Bob after selecting Resource1 and
Phil, I think it is easy to accomplish by adding property on the edge.
Let us say you have Person --->tagged---> Resource, where "tagged" is edge.
You could add "tag_type" property (link to tag vertex) on this edge class.
Alternatively, if finding what resources are tagged with which particular
Hi Colin,
Maybe I'm missing something obvious but I still can't envisage how the 3
node model will work.
In the example data below I can determine that both Bob and Alice have
tagged Resource1 and that Resource1 has been tagged 'red' and 'blue'. I can
also determine that Bob has applied the 'red
Hi Phil,
You can accomplish everything you want with the three node model.
With some of the more specific queries you will need to use nested select
statements to filter out specific tags or persons (or even resources if you
wanted).
Let me know if you need further detailed help.
Best regards
Thanks Patrick, that could work. The only thing I would be concerned about
is the implications for querying the data, it would mean multiple instances
of the Tag edge for the same tag content which would probably result in
more complex and possibly less efficient queries for anything relating to
I was planning to have only one instance of each tag; this seems more
'normalised' to me and may make certian queries easier/more efficient e.g.
discover all the unique tags for a resource without having to group them,
or find all resourses with a particular tag.
It's not set in stone though an
Hi Phil,
Another quick question and then I'll respond to your last post based on
your answer. Will there be a single instance of each tag (say "Family
Photo") that multiple Person instances and Resources will use, or will
there be multiple tag instances with the same name and properties just
Phil,
What if you made the Tag itself the Edge class, and perhaps add a couple of
properties to the edge to give it appropriate context? Then your three-node
graph above becomes a two-node graph with multiple "Tag" edges between
them? You could add the timestamp to record when the Person add th
Hi Colin, thanks for your reply.
1) Yes a Resource can have multiple tags
2) I want to determine who applied a specific tag to a specific resource
(could be more than one person).
Multiple users may apply the same tag to the same resource, which is where
I think your suggestion may not work to
Hi Phil,
Two quick questions:
1) Can a Resource have multiple tags applied to it?
2) You want to be able to determine who created a specific tag, right?
If my assumption is correct based on looking at your relational schema, I
would create an edge between the Person and the Tag directly.
