TopBraid EDG lets you export metadata and data to JSON-LD, RDF/XML, N-Triples, Turtle, TriG, JSON, CSV, TSV and XML through pre-built functions, sparql endpoint and graphQL endpoint.

Pre-built export options are available from the Export page (tab) for an asset collection or a workflow (working) copy of an asset collection. These options are described below.

  • Additional exporters can be configured using Export modules that are part of TopBraid EDG’s platform. If your organization configures a new custom export to appear on the Export page, you will see it listed as one of the available options alongside with the pre-built exporters.
  • Your organization may also deactivate some or all of the Export page options. This decision can be made on a per collection basis on the Manage page (tab). In this case, you will see less export operations than described here.

In addition to being available on the Export page, all export operations can be executed as services.

You can also export data directly from the page that let you view and edit asset collections through: 

 

Export Data as a Graph

 

These operations let you export collection’s data in a standard RDF serialization format.

To export subsets of an asset collection’s data according to custom criteria and sorting, note that EDG’s Search screen provides fine-grained control over the data to display on the Search Results area. That form’s gear menu offers several choices to export the results into spreadsheet-compatible formats (e.g., for Excel). See Editor in EDG

TriG with inferences” adds a dedicated graph named urn:x-topbraid:inferences, which has any triples inferred via SHACL or SPIN rules; note that this computes on-the-fly and might be very slow.

Browser interactions might vary: displaying the data directly or via a kind of view source command. Alternatively, instead of directly clicking a format link, the browser might provide (on the link) a right-click menu option to save the link target to a file (i.e., without explicitly displaying the link result in the browser). A dialog box will prompt for the file location and name.

Publish Glossary for Explorer Users

 

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 that 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).

 

It also lists any included asset collections that might also require publication.

 

Ensure that all included graphs are either already present on the Explorer server or published along with the asset collection.

 

Changing the status causes the following action.

 

Current Status Chosen Option Result
Unpublished Published Sends a copy of the asset collection and selected includes to the Explorer server. Changes the source collection’s status to Published.
Published Update Published Copy Re-sends a current copy and selected includes to the Explorer server, overwriting the previous version(s). Keeps the source collection’s status as Published.
Published Unpublished Deletes the asset collection on the Explorer server. Changes the source collection’s status to Unpublished.

 

 

GraphQL Queries

 

This allows users of the collection to run new or saved GraphQL queries on it. For users unfamiliar with GraphQL, there is an included link to a tutorial inside TopBraid EDG and TopBraid Composer. For more information on GraphQL visit https://graphql.org/ or the TopQuadrant tutorial here https://www.topquadrant.com/technology/graphql/.
