Leo, the way to copy a file into Composer's workspace is to use copy/paste from the file system to the Navigator View in Composer.  The Eclipse Navigator view needs to know about the file and therefore it is best if this is done from the Composer Navigator view.

See the "How do I open a RDF/OWL file in Composer?" FAQ at http://www.topquadrant.com/knowledge-assets/faq/tbc/

Hi Leo,

 

It is hard to respond without having an example. Could you send one of the files you are having problems with? Also, please provide a sequence of the steps you take. For example, are you creating a new project and then doing File->Open?

 

The best approach is to copy a file into TopBraid workspace (within a project/folder of your choice) and then open it by double clicking. Do you get any errors if you do it this way?

 

 

Leo: When I copy a file directly into the project from Windows (into the TBCMEWorkspace-4.4/project_folder/project/), and then try to open that file within TopBraid, TB complains that “Can not open file <file>. Reason: The file <file> does not exist.” So any file transfer you do outside of TB, even into the requisite project folder that TB has defined, is not recognized.

 

I really can’t send the file publicly. But the errors I mention happen with every file, as far as I can tell.

 

Thanks,

Leo

 

 

TopBraid workspace is a named graph store that manages all graphs within it. There is a graph registry that keeps track of all base URIs and their mappings to files – whether they are RDF serialized files, files in other formats TBC auto-converts on open to RDF (such as spreadsheets and XML) or connectors to databases. This is needed, for example, to resolve imports.

 

As an aside, creating a project doesn’t really do anything besides providing a structure for placing a file in. Another reason to create a project is that projects are a unit of deployment to TopBraid Live server – you deploy assets from TBC to the server as projects.

 

 

Regards,

 

Irene

Subject: [topbraid-users] opening an owl ontology in TBCME, thereby creating a project automatically, errors

 

I am using TBCME 4.4, and systematically, whenever I try to open an OWL ontology file outside of TBCME, even those without any imported ontologies, I choose to create a project, and TBCME does so. However, it always generates 3 errors.

 

The error log doesn’t show much:

 

ERROR [Thread-25] (ErrorHandlerFactory.java:84) - {E201} Multiple children of property element,

An exception stack trace is not available.

eclipse.buildId=unknown

java.version=1.7.0_55

java.vendor=Oracle Corporation

BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US

Command-line arguments:  -os win32 -ws win32 -arch x86_64

 

And it only displays that one error, not three, with a whole lot of warnings, basically pairs of the following:

WARN [Thread-25] (ErrorHandlerFactory.java:77) - {W102} Unqualified property attributes are not allowed. Property treated as a relative URI.

WARN [Thread-25] (ErrorHandlerFactory.java:77) - {W136} Relative URIs are not permitted in RDF: specifically <IRI>

 

The OWL or RDF files never look erroneous, and Protégé never complains (which is not, obviously, definitive).

 

Is this a known problem? It really does this for every file that I bring in in this way.

 

Thanks,

Leo
