Yes you can have multiple inheritance in the newer versions.
create class C extends A, B;
alter class C superclasses A, B;
--Add A superclass
alter class C superclass +A;
--Remove B superclass
alter class C superclass -B;

I have a time series modelled in the graph way
year(linkmap)-month(linkmap)-day(linkmap)-hour(linkmap)
I have two other vertices which are events and users
I want to join events to the time series. Is this best achieved by using an
edge or a linkset?
I have a time series model where I create an edge between a hour vertex and
an event vertex. The edge is called registered_event.
I have tried the following query but it is not giving me results. Any ideas?
select expand(month[12].day[3].hour[23]).out('registered_event') from Year

Using one connection for all requests didn't work well, looks like the

From what I undertand Oriento will open a new connection as needed when you
try to access the db - at what point is this connection closed? Are the
connections threadsafe?

Hi Luca!
The only suggestion I have - add more examples.
I got back to OrientDB after more than a year break (it looks way better I
have to admit) and I still see a lack of documentation.
I'm struggling to build a query that returns edges' properties along with
vertices' ones and I can't find any

You now have my interest peaked. That is very interesting to know. Since we
will be holding metadata (like the schema/ mapping) about our data anyway,
this means we can take advantage of the schema option and not storing field
names. Cool.
Now to just get more understanding about ODB's
I've now read in the docs there is an option to do preallocation to
basically pack on extra space for changing record sizes (through updates),
in order to avoid movement of records. Is this still true? The
documentation is a bit thin on explaining it.

My schema is pretty simple. Vertices are connected with Edges of type
RELATED which have property count.
2 vertices can have connection in both ways at the same time.
Considering that any database must store data somewhere and that somewhere
is always in the file system of the server, then it might be safe to say,
there is certainly a limit, usually fixed by ulimit in the OS (Linux). I am
also interested in the answer though.

(1) I don't work for OrientDB, (2) I am not familiar with the Tinkerpop
APIs outside of OrientDB.
OrientGraph.getVertices() returns an iterator, not a pipe. Gremlin adds a
DSL method *_()* that will turn an iterator into a pipeline, from which you
can do the normal Gremlin queries.
Blueprints is nice, but it is not a cross-graph-database panacea.
there is much wisdom in this, that I think the graph community could use to
hear from.

Much like you told the SQL engine to use an index (select * from
INDEX:V.testProperty ...), you need to explicitly use indexes from the
graph API, as follows:
*Java:*
OrientVertex result = g.getVertices( V.testProperty,
