Hackathon

Module 1

The main goal is to define State-Aware RML (StARML?) rules that are able to produce versioned and state-labeled entities (i.e. created, updated, deleted) entities. With the help of team 3, the produced versioned entities should be streamed into an LDES server (e.g., ldes-solid-server or VSDS-LDESServer4J) through a connector-architecture workflow.

Prerequiresites

• Have Java and the RML mapper (v6.3.0)

Download RML mapper

wget https://github.com/RMLio/rmlmapper-java/releases/download/v6.3.0/rmlmapper-6.3.0-r371-all.jar

Running mapping standalone

Run the mapper with example data

java -jar rmlmapper-6.3.0-r371-all.jar -m ./module1/mapping.ttl

Now you can find the generated LDES in the file: out-buienradar-change-observations-change.nq

Running again leads to the file being empty as no new measurements are created

State

If we want to start over again and remove the state, just remove it in the /tmp directory:

rm /tmp/kmi_sensor*

Integrated Raw data to real versioned LDES ft. SDS

See other branch (generate), still needs to be merged

Module 2

See the module 2 directory

Module 3

See the documentation in m3.
