Best way to handle sequences

[franzlst]

Ontologies do not directly support sequences, i.e. properties with multiple ordered values. This is why for this hasFirst and and hasNext properties (or subclasses properties) are used

Dummy example:

p = Progress()
s1 = Step()
s2 = Step()
p.hasFirst = s1
s1.hasNext = s2

As it is a bit cumbersome to access such sequences, I'm wondering how this could be simplified using Owlready2. I would like to be able to access (both read and write) such information using e.g.

p.steps

I could imagine that could be implemented using custom Python methods. Would this be the appropriate way or are there better alternatives?

Hi,

Yes, I think it is the appropriate approach. You can create a get_steps() method, and then a "step" property if you want to access it without having to call the method.
