Now that a region object has a snippet property, we don’t need the analysisToolLogFileContents object any more. It just contains a fileLocation , a region , and a snippet . But a physicalLocation object has all those things now ( physicalLocation.fileLocation , physicalLocation.region , and physicalLocation.region.snippet ). So we can get rid of the analysisToolLogFileContents object, and change the type of the result.conversionProvenance property from analysisToolLogFileContents[] to physicalLocation[] . That change will be part of the change draft we discuss at the next TC. Larry
