All regular edits trigger the execution of teamwork:EditRules. So you
could implement a batch exporter to take a current snapshot and produce
external triples from it (e.g. using SPARQL Update), and then do an
EditRule that writes the delta of each change, again as a SPARQL Update.
Note that SPARQL Update will not preserve blank node identifiers across
graphs.

In that thread, Irene made the following comment:
Today, EDG can offer a solution where data is located in its
repository as well as in another triple store. Using EDG Data
Platform (replication server -

changes in the data in EDG will be automatically synchronized
(pushed) to an external triple store as micro transactions.
However I am confused by the Data Platform documentation as it appears
to focus on data synchronization among EDG servers, although I can see
the RDF Patch methodology is certainly applicable to updating other
triple stores.

Could you please point me to the right direction? Ideally I wish it
could be done without Data Platform which is not covered in our EDG
license. Thanks!
