Hello
I have been encountering challenges when trying to export complex graph designs created in Stardog Designer into a reusable format, such as RDF or TTL. While simpler graphs export without issue, designs involving nested relationships, custom ontology alignments / multi-layered connections seem to result in incomplete or corrupted files. 
For example; a project I recently worked on included several namespaces and mappings to external ontologies. Upon exporting, certain triples were omitted & others appeared malformed when viewed in external RDF validators. Additionally, attempts to re-import the exported file back into Stardog Designer failed; indicating syntax errors not present in the original design. This issue affects the ability to collaborate across teams; especially when exporting data models for use in other tools. 
It would be helpful to understand whether there are specific limitations or known issues with the export feature for complex designs. Additionally, implementing enhanced error reporting during export / a validation tool to preview exported files within Stardog Designer could significantly improve usability.

I'm curious to hear if others in the community have faced similar problems and any workarounds or solutions they've found.
Thank you !
