Could you show us more details of the error message, or, ideally, the XSD file itself?

Now I am getting the following error while importing it into TOPBRAID Composer "Failed to parse XSD Document Failed to parse XSD Document with the URL file:/C/...." Appreciate if someone can give what be wrong here?

One of the import menu options is about connecting to relational databases. This would have the same outcome as converting the physical model. We are not familiar with the Powerdesigner pfm file format and don't have a special converter for it. What is additional useful information beyond the schema itself is available in your data dictionary? For example, it probably has descriptions of data elements. This is certainly good to have. If you can export it as a spreadsheet it would be easy to import it. You can simply place .xsl file into TBC workspace and double click to open. Each row will become RDF resource. Columns will become properties. I expect you will need to do some post-processing with SPARQL.

We have a physical data model in Powerdesigner pfm format. This model shows all tables, data elements and relationships among different tables. 2. We have a data dictionary with the list of data elements and their metadata (about 20 columns) of information. Which of these artifacts is best for start creating our initial ontology and any ideas of steps should be taken for the path selected. I would appreciate if someone can give us some detail pros and cons and steps.

I need to import a PowerDesigner (pdm file) Data model into topbraid. Any tips on how to do this?
