Looking into "more usual", I can think of keeping the present notation
for groups and datasets. Altough it does not make a distinction between
the two, it has never posed a problem to me.
OK, a dataset can be identified as a leaf of the tree (once the
attributes are distinguished).
Fine :-)
Regarding attributes, I agree that they should be denoted in a
different way.
I propose
trajectory
\-- group1
\-- position
| \-- sample
| | +-- minimum
| | +-- maximum
| \-- step
| \-- time
Or
trajectory
\-- group1
\-- position
| \-- sample
| | --- minimum
| | --- maximum
| \-- step
| \-- time
that is, using "+--" or "---" for the attributes.
I prefer "+--", it provides still some connection to the line above. An
alternative I was thinking about was to put the attributes at the same
line as the dataset:
trajectory
\-- group1
\-- position
| \-- sample --> minimum, maximum
| \-- step
| \-- time
The attributes on the same line makes it less readable, the "+--" is
adopted.
Shall optional attributes be enclosed in brackets? E.g.,
trajectory
\-- group1
\-- position
| \-- sample
| | +-- [minimum]
| | +-- [maximum]
| \-- step
| \-- time
Excellent idea, it is a quite common notation.
