mtconnectCategoryPropertyPath

The "mtconnectCategoryPropertyPath" property is an optional string that specifies the location in the JSON document to store the MTConnect category of the data item. Omit this property to omit it from the JSON document. This property defaults to null. 

When the FairCom MTConnect connector collects data, it generates a JSON document and stores it in the database. The connector extracts the name of the parent element that contains the data item. The parent element may be <Samples>, <Events>, or <Condition>. The connector maps the element name to one of the following category strings: "SAMPLE", "EVENT", or "CONDITION". It then puts the category string in the JSON document at the location specified by this property. You may use a simple property name, such as "temperatureCategory", or a complex JSON path, such as "temperature.category". For examples, see Example property paths that group related properties.

In the following MTConnectStreams XML document returned over the MTConnect protocol, the data element has a dataItemId of "X1_Stamper1_Temperature". The element is named <Samples>, which maps to the category of "SAMPLE".
