a primary design goal during the development.

The prerequisities to run this benchmark are:

 - Apache Jena - the distribution should be downloaded and extracted to the hard drive

 - Apache Tomcat 9 - the distribution should be downloaded and extracted to the hard drive. Then, The JAVA_HOME environment variable must be set manually.

 - Apache Jena 3.2.0 - the distribution should be downloaded and extracted to the hard drive

 - Apache Tomcat 8.5 or higher - the distribution should be downloaded and extracted to the hard drive. Then, The JAVA_HOME environment variable must be set manually.

Usage:

0) If you intend to use the provided pre-generated data or custom dataset, proceed directly to step 3 and use the optional parameter to specify the correct input file.

1)  [Optional] Run the script Generate-CSVs.ps1

    The script generates CSV files into the CSV-Data folder.

    Optional parameters:

        -Floors [Default: 3] - number of floors in each building 

        -Rooms [Default: 10] - number of rooms in each floor    

    Pre-generated CSV files for the default configuration are available in the CSV-Data folder.

2)  [Optional] Run the script Generate-Triples.ps1

    The script generates an N-Triples file into the NT-Data folder, based on the CSV files located in the .\CSV-Data folder.

    Pre-generated NT file for the default test mock-up is available in the NT-Data folder.

    Optional parameters:

        -InFolder [Default: .\CSV-Data] - location of the source CSV files generated by Generate-CSVs script

        -OutFile [Default: .\NT-Data\data.nt] - location of the output NT File

    The process of Triples generation is universal and can be performed with existing CSV when using real facility data 

    instead of a generated mock-up created by Generate-CSVs script.

    Pre-generated NT file for the test mock-up with the default size is available in the NT-Data folder as sample.nt.

3)  Run the script Create-TDB.ps1

    The script will create the TDB triplestore using the Apache Jena framework.

    Optional parameters (no need to set them if they not differ from the defaults):

    Optional parameters:

        -TDBPath [Default: \apache-tomcat-9.0.0.M19\webapps\sbms\WEB-INF\tdb] - location of the resulting TDB directory

        -NTPath [Default: .\NT-Data\data.nt] - Path to the source NT file

        -JenaRoot [Default: \apache-jena-3.2.0] - Path to the directory with the Apache Jena distribution

    Statistics of the TDB can be found in the <Your tdb location>\stats.opt file

    If you intend to use pre-generated sample dataset, run the command as follows:

    Create-TDB.ps1 -NTPath .\NT-Data\sample.nt

    Statistics of the TDB can be found in the <Your tdb location>\stats.opt file.

4)  Deploy the Semantic API into the Apache Tomcat (see Readme on the project site)

    If you did not start the Apache Tomcat in the previous step, use the -ManageTomcat switch. You can also set the path to 

    the Apache Tomcat installation directory by the -TomcatHome param (Default is C:\apache-tomcat-9.0.0.M19)

8)  [Optional] Stop the Apache Tomcat

    Execute the bin\shutdown.bat script if you did not use the -ManageTomcat option and started the server manually in the step 6)
