TopBraid EDG supports the export of metadata and data to JSON-LD, RDF/XML, N-Triples, Turtle, Turtle+, TriG, JSON, CSV, TSV and XML through pre-built functions, a SPARQL endpoint and a GraphQL endpoint.
Search and the SPARQL Query and SPARQL Results panels support the export of subsets of the data in an asset collection based on custom criteria and sorting.
These panels provide fine-grained control over the selection of data.
Menus in these panels offer several choices to export the results into spreadsheet-compatible formats (e.g., for Excel) as well as other formats.
Sorted Turtle includes an extension that supports the TopBraid reification capabilities.
Reified statements in EDG are converted to standard RDF Statements in the exported file.
Sorted Turtle+ is an extension to the standard Sorted Turtle that supports TopBraid’s reification capabilities known as “RDF-star” or “RDF*”.
In this case, the serialization is Turtle+ and requires a Turtle+ parser in order to import the file.

RDF-star is not yet an official W3C standard, but work on the specification is well under way. TopQuadrant is one of the contributors to the specification document. In the meantime, many of the RDF technology vendors, including TopQuadrant, already implemented support for this concept.
Browser interactions during export vary: the data may be directly displayed, via a kind of view source command or
the browser might provide (on the link) a right-click menu option to save the link target to a file, without first displaying the link result in the browser,.

On an EDG server that is paired with a TopBraid Explorer Server (for read-only access), managers can publish it to the Explorer for viewing.
Note
The working copies of all published asset collections might or might not be viewable, depending on the Explorer’s administrative configuration.
Any manager of an asset collection can control its Explorer publication status by selecting Export > Publish Glossary for Explorer Users.
The view shows a Status drop-down for the asset collection, which indicates whether the asset collection was ever Published or not (Unpublished).
