MOCHA Open Challenge at a glance

The aim of this challenge is to test the performance of solutions for SPARQL processing in aspects that are relevant for modern applications. These include ingesting data, answering queries on large datasets, versioning data, browsing and serving as backend for applications using Linked Data. The MOCHA Open Challenge will test the systems against data derived from real applications and with realistic loads. The open challenge comprises the following tasks:

- Task 1 (Data Ingestion) will measure how well systems can ingest streams of RDF data.
- Task 2 (Data Storage) will measure how well data stores perform for different types of queries.
- Task 3 (Versioning) will measure how well versioning and archiving systems for Linked Data manage evolving datasets and queries evaluated across the multiple versions of said datasets.
- Task 4 (Browsing) will check if existing solutions perform adequately for applications that address browsing through large data sets.

Small test data and documentation are available now for all the MOCHA tasks:
