Hi,

Thanks for the replies... will look at the suggestions and links provided
and see how far I go.

Cheers,

Stein,

I am assuming this may be part of the larger project ABS is undertaking.
You may wish to talk to Alistair Hamilton at ABS as he is one of the
people involved in setting up some addtional training etc within ABS on
DDI.

If you are focusing on variables you may wish to look at some of the SPSS
and SAS to DDI 3 tools like DeXT and one by Achim Wackerow. These are on
the ddi tools page http://tools.ddialliance.org/?lvl1=library

This will let you see where elements you are familier with from
statistical packages reside within a DDI instance.

Coming from a questionnaire perspective I would suggest talking to the
developers at Algenta  (Jeremy Iverson <jeremy at algenta.com>). While their
tool is commercial they have a beta version you should be able to use and
again create DDI output that will provide you with a better sense of how
the content is arranged.

If you have not already done so, download the schema package. It contains
both an Overview and Users Guide which may be helpful. I don't know how
helpful the current set of best practices will be
http://www.ddialliance.org/DDI/bp/ as they don't tend to deal with this
basic use case.

If you have specific question, either post them to the list or directly to
me. I chair the Technical Implimentation Committee and provide user
support to DDI.

DDI Users email list, where other users (many of whom I know have
experience in Blaise) can respond to your question as well.  There is a
particular section of the DDI that would be use to document the variables
(specifically in the logical product module:
http://gandalf.opendatafoundation.org/infocenter/topic/net.sf.ddialliance.help/html/modules/ddi3_logicalproduct.html
), whereas most of the other elements document other contextual information
about the data (collection, storage formats, etc.).

I am currently involved in a pilot project to see if we can map a small
survey to DDI standard.  I've been reading some of the papers and
presentations on the net but am still a bit confused about how we go about
mapping it.

from our data store (star schema) to Blaise (edits and data entry) and many
others in-between.  For this pilot project, our initial goal is to map
every variable in the survey form to DDI - I'm writing to ask if there are
any tools that will allow me to do this easily or any samples that I can
work through.  I initially looked at the basic structure of DDI and there
are a lot of elements to choose from for me to know whether I'm mapping
things correctly or not.
