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 challenge will test the systems against data derived from real
applications and with realistic loads.

This year, the 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 perform when they manage multiple versions of large data sets.
-Task 4 (Browsing) will check if existing solutions perform adequately for applications that address browsing through large data sets.

Training data and documentation are available now for all the MOCHA tasks:
Task 1: http://hobbitdata.informatik.uni-leipzig.de/MOCHA_ESWC2018/Task1/
Task 2: http://hobbitdata.informatik.uni-leipzig.de/MOCHA_ESWC2018/Task2/
Task 3: http://hobbitdata.informatik.uni-leipzig.de/MOCHA_ESWC2018/Task3/
Task 4: http://hobbitdata.informatik.uni-leipzig.de/MOCHA_ESWC2018/Task4/

Participants will be expected to describe their solution and results on the training datasets over a 5 page paper. In particular, a short summary of the approach chosen, a link to the experimental results and an analysis of the strengths and weaknesses of the approach are expected.
