[DDI-SRG] request for assistance

[Sanda Ionescu]

Hi, Wendy.
 
I'm beginning to look "in earnest" at the candidate draft and I have
questions...
I anticipate needing lots of clarifications as I attempt to update my
old examples and create the new one.
So please bear with me!
I expect you are willing to answer, as you have always been, and one
question would be - do I send my questions only to you, or do I send to
the entire SRG?
 
And here comes the first batch (as I'm looking at Identification):
1. Can objects be referenced even if they sit "outside" maintainable
objects? (It was my understanding that only maintainables can stand
alone, all others need to be within a maintainable?)
2. name of maintainable object (in the URN) - is this actually the name
of the ddi tag?
3. maintenance agency (in the URN) - is this information copied from the
Identifying Agency tag ?, and
3b. if the above needs to be in the form of a URL, it means the ddi tag
needs to contain a URL, no? should it not have a URL type rather than
NCNAME?
4. If the version of an identifiable element is always inherited from
above, why does it need to be stated in the URN? (see your example in
the manual - a variable is not versionable, so then why do we need its
version in the URN)
5. It is my understanding that all of the versioning tags need to be
filled in for maintainables, or else we would not be able to build URNs?
and...
6. If a maintainable lives within a maintainable (i.e. variable scheme
within study unit) will it inherit the versioning info from the
maintainable above (if not specified), or does this need to be specified
for each and every maintainable?
 
Thanks Wendy,
I really appreciate your help.
Sanda.
