Sven,

I just tried a similar import, and it worked as I expected. 

Just to make sure I understand correctly, Category is the first column of
your tab-delimited file, and it's declared as a class in the target
spreadsheet, and all the other columns of the tab-delimited file are
properties of the Category instances, right? 

Also, what release of TBC are you running, and on what platform? 

Thanks,

Bob DuCharme

Subject: [topbraid-users] Topbraid Composer: class error when importing a
spreadsheet into an existing ontology

Hi,

I have the following problem with importing an excel spreadsheet into
an existing ontology:

Environment:
I use two files: one for the schema definition (core.rdf) and one for
the instances (fact.rdf). The fact.rdf has imported the core.rdf, so
that the schema in fact.rdf is also known.
The core.rdf should be used for different facts with different
namespaces (each of them in its own rdf-file). For this reason, the
scheme must/should be outsourced.

My procedure:
Now I want to import my facts from an Excel spreadsheet. For this I
open the fact.rdf and use the import function of the TBC. There I
choose the option "Import Tab-Delimited Spreadsheet File" from the
category "TopBraid Composer".
In the following Assistant-Window I select my file and choose the
option "Import to the current ontology (uses the current namespace". I
skip the following window with the Next button.

The Problem:
The class Category, that I have defined in the first column (first
row) of my spradsheet wasn't found. This class exist in my schema
definition core.rdf. So I think, that the import function dosn't work
with imported classes (an other namespace). But the imported
properties (also defined in core.rdf) are known.

Verification that my spreadsheet works:
I have imported the same spradsheet into my core.rdf and it works.

Can anyone help me? How can I use the 2 files and the import from an
spreadsheet with classes from an other namespace? I don't understand
that the TBC identifies imported properties, but not work with
imported classes.

Regards,
Sven Miersch
