Database Exports for the RDF Graph Database-as-a-Service on S4

A new feature has just been added to the fully managed RDF graph Database-as-a-Service (DBaaS) running on the S4 platform – full database exports in various standard RDF formats. Now it is possible to instantly download a data dump for the RDF database that can be used for local backups, for instantiating other database instances with a copy of the data, or even for migrating the data to another database if the developer no longer wishes to use the RDF graph DBaaS available on the S4 platform.

The time for completing a full database export of course depends on the database size, though for the Micro instances (1 million triples) freely available on S4 at present, the export should take only a few seconds.

Step-by-step Example

The 1st step for activating a full database export is to choose “Create a full DB export” from the “Database” section of the S4 Management Console:

The next step is to select the RDF serialisation format for the database dump. The supported export formats are:

    • Turtle (default)
    • N3
    • RDF/XML
    • JSON-LD
    • N-triples
    • N-quads


When the export is completed, the database information panel on the S4 management console will be updated:


At this point, the database dump is available for download:





The archived ZIP file will contain one file per repository in the DBaaS, in the format specified at data export time:




Final words

With the full database exports available on the S4 platform it is now easy to get a local copy of the data in the RDF graph DBaaS and use it to bootstrap local database instances, share the data with other developers and collaborators, or even migrate to a different RDF database.

If you haven’t already done so, register for a free developer account for the Self-Service Semantic Suite (S4), take a look at the developer’s documentation, configure your own RDF graph database in the Cloud and start building smart data prototypes with RDF and SPARQL!
