In a factory producing metal parts, various machining processes, such as turning and milling, lapping, grinding along with laser marking, quality check and packing takes place. Workers are assigned to corresponding machine to carry out these operations for work orders on various metal parts. The company wants to monitor the assignment of workers along with machine allocations.

Production data on 10 work orders. Important columns are:

• Activity: Type of process occurred

• Resource: machine used

• Start timestamp: begining beginning time of the process

• Complete timestamp: end time of the process

• Span: the duration of the process

• Work Order: # of work order

• Part Desc. : The type of the part produced

• Worker ID: Identifier of the worker assigned to the machine for the process

Note: The data is a part of and customised from the original data retrieved from http://fluxicon.com/disco/ presented by Dafna Levy (dafnal@nool.co.il)

The following competency questions should be available for query and the answers to the query should match the corresponding answers.

The data is loaded to GraphDB (https://www.ontotext.com/products/graphdb ) modeled using IOF Core (spring release candidate) and SWRL rules (see Pre-process steps of Test Case # Allen-2).

Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz 2.59 GHz with 32.0 GB RAM

Each CQs are tested with the following SPARQL queries as mentioned in the following table using https://www.ontotext.com/products/graphdb workbench on the KG below.

All tests are passed as shown in the following table.
