Hi all, Scott, Irene, thanks for the replies.
Currently our model is not so complex. We have a file with concepts, one with properties, one with abbreviations of concepts and several thesauri imports. The concept file had structure with several top level branches. Each branch goes quite deep, up to ten levels sometimes. Many concepts also have multiple parents. What I had done is split the file with concepts by deleting all the top branches except ones. Save that as a different file and start over for the other branches using the original file. That worked however a lot of lines in the raw data, looked at using a text editor, should not be there but in another file. Also I saw that concepts that were previously deleted from the model still left some lines in the raw data, although they were not show in TBC. For this reason I posted this subject. After the advice from Scott I took those separate files, opened the branch to the bottom (leaf nodes) and selected all resources, put them in the basket and add them to a new rdf file. I did this for all the new files with a branch and it has worked. All files are clean now. After importing all the model parts into one rdf gives the exact model as before the split.
