I was able to create and populate the auction database,
but could not run any queries.
(It seemed to hang, but was taking no CPU time.)

Thanks for making this available.

I basically followed the instructions in QuickStart.pdf.
I am running on Windows XP, and entering these commands
in a Command Prompt (aka DOS box).
I noticed that I had to also do these, which should be added to
set sedna_home=c:\apps\sedna
set path=%path%;%sedna_home\bin

Here are the last few lines caused by 
tr auction load_data.xquery

UPDATE is executed successfully

But then this produced no output, even after several minutes:
C:\apps\Sedna\examples\databases\auction>tr auction sample01.xquery

C:\apps\Sedna\examples\databases\auction>more sample01.xquery
   Return the name of the person with ID `person0'
   registered in North America.

for    $b in document("auction")/site/people/person[@id="person0"]
return $b/name/text()

C:\apps\Sedna\examples\databases\auction>echo return "tolkin1"

C:\apps\Sedna\examples\databases\auction>cat t1.xquery
return "tolkin1"

C:\apps\Sedna\examples\databases\auction>tr auction t1.xquery

Again, no output.

Hopefully helpfully yours,

There is nothing so practical as a good theory.  Comments are by me, 
not Fidelity Investments, its subsidiaries or affiliates.

> 2) efficient support for unlimited volumes of document-centric and

> system can be
> efficiently used for solving problems from different domains 
> such as XML
> data querying, XML data transformations and even business 
> logic computation

> The first release of Sedna v0.1 is a ready-to-use system that 
> provides the

> - Support for the W3C XQuery language (partial support for the latest

> - Support for a declarative update language (it is based on the XQuery
> update proposal by Patrick Lehti)
> - Native XML data storage structures designed for efficient 
> support for
> XQuery and its data model
> (no underlying relational or another DBMS). The XML data 
> storage is based on
> descriptive schema (also called DataGuide)
> - Administration via easy-to-use command line utilities
> - Supplied with extensive documentation including Quick Start
> Sedna is available for free for commercial and non-commercial usage.
> Have a look at our web site
> (http://www.modis.ispras.ru/Development/sedna.htm) and download Sedna.
> Any feedback is extremely welcome!
