Hi Fles, Blazegraph does support JSON-LD [1]. If you can convert your MediaWiki dump into JSON-LD, you should be able to load it directly. Thanks, --Brad [1] https://www.w3.org/TR/json-ld/ On Wed, Jun 13, 2018 at 2:36 AM Fles Duan flesd@users.sourceforge.net wrote: Hi there, I'm trying to load rdf data in json format into Sparql using BlazeGraph's REST API.

Hi David, Starting with the 2.0.0 release [1], the HA journal capabilities are no longer included in the open source releases. Feel free to contact us (beebs at blazegraph.com) for information on other options.

Don, You may need to restart your Blazegraph instance. Also, try enabling the Analytic Mode [1] for the query that is causing this issue. https://wiki.blazegraph.com/wiki/index.php/AnalyticQuery Thanks, --Brad On Thu, Aug 24, 2017 at 7:10 AM, Don Pellegrino donpellegrino@users.sf.net wrote: When submitting any query to Blazegraph via the Blazegraph Workbench, the following error is generated: "java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: GC overhead limit exceeded" It seems...

Tim, We don't have a specific Blazegraph recipe, but in general a model like the SQS approach described here: https://stackoverflow.com/questions/32477255/how-to-setup-cross-region-replica-of-aws-rds-for-postgresql would be effective. Good luck! Thanks, --Brad On Thu, Jun 15, 2017 at 4:08 AM, Tim Clarke chclarkee@users.sf.net wrote: Thanks Brad - that helps a lot.

Hello, All you need to do is to configure a namespace to use the quads mode, load data that has named graphs (nquads or other), and then you will be able to use the quads mode in your queries and updates. https://github.com/blazegraph/database/tree/master/bigdata-sails/src/samples/com/bigdata/samples On Thu, Apr 27, 2017 at 11:51 AM, martys_machine <martysmachine@users.sf.net wrote: I am interested in exploring Blazegraph's Quads mode to use named graphs within my database, but I cannot find a good...
