Setup

Install dependencies

• npm install

In server.js:

• Set hostname and port to the server's hostname and port
• Set environment variable RACO_PATH to the path of raco/.
• Set environment variable GRAPPA_PATH to the path of grappa/.

Inserting datasets

• Create a csv file (1 dataset entry per line)
• csv schema: user name, program name, relation name, uri (for clang it is http://hostname:port), number of tuples, backend the data can be used on, the number column names, a comma separated list of column names followed by column types
• example: public,adhoc,sp2bench,http://my.radish-server.org:1337,100000000,clang,3,binary,subject,predicate,object,INT_TYPE,INT_TYPE,INT_TYPE
• Note: user name, program name, relation name, and backend are the primary keys
• the uri should be user-accessible as it will be used for direct downloads
• Run the command: ./datastore.py insert_new_dataset -p (filename.csv)
