## Prepare the data
**Warning: Do not forget to clone the submodule**
### Clone the submodule
```zsh
git submodule init
git submodule update
```
or
```zsh
git clone --recurse-submodules -j8 {address of the repo}
```
### Generate fragments
```zsh
./run_evaluation.sh install-comunica
yarn install
./run_evaluation.sh install-injestor
./run_evaluation.sh download-dataset
```
to generate the fragmentation with 100 nodes
```zsh
./run_evaluation.sh dahcc-1-participant-one-ary-tree-100 --server
```
to generate the fragmentation with 1000 nodes
```zsh

## Run the queries
To run the queries you have to run the following command schema.
```zsh
node comunica_runner.mjs -f ./evaluation/query/{}.ttl -m {TREE-GUIDED|TREE} -r http://localhost:8080/0.ttl -d http://localhost:8080/metadata.ttl
```
For example
```zsh
node comunica_runner.mjs -f ./evaluation/query/Q2.ttl -m TREE-GUIDED -r http://localhost:8080/0.ttl -d http://localhost:8080/metadata.ttl
```
It will output something like
```json
{"nResults":1,"timeExec":5111.714145,"nRequest":3}
```
