Based on the document you have sent me, for the simple python script that runs like this: kml.python [input][outputmet]. I need to have the config file like:
<?xml version="1.0" encoding="UTF-8"?> <cas:externextractor xmlns:cas="http://oodt.jpl.nasa.gov/1.0/cas";> <exec workingDir=""> <extractorBinPath>/usr/local/extractors/mp3extractor/mp3PythonExtractor.py< /extractorBinPath> <args> <arg isDataFile="true"/> </args> </exec> </cas:externextractor> Do I have to specify the working directory like the first line: <exec workingDir="">. Because I don't see that line in the peate's sample file. Also I see the python extractor has these lines that mines doesn't. Is this the reason my python script doesn't get run? The python file I have simply parses the file and generates the output met. cmd = "java -jar /Users/woollard/Desktop/extractors/mp3extractor/" cmd += "tika-app-0.5-SNAPSHOT.jar -m "+fullPath+" | awk -F:" cmd += " 'BEGIN {print \"<cas:metadata xmlns:cas=" cmd += "\\\"http://oodt.jpl.nasa.gov/1.0/cas\\\";>\"}" cmd += " {print \"<keyval><key>\"$1\"</key><val>\"substr($2,2)\"" cmd += "</val></keyval>\"}' > "+fileName+".met" #!/usr/bin/python import os import sys fullPath = sys.argv[1] pathElements = fullPath.split("/"); fileName = pathElements[len(pathElements)-1] fileLocation = fullPath[:(len(fullPath)-len(fileName))] productType = "MP3" cmd = "java -jar /Users/woollard/Desktop/extractors/mp3extractor/" cmd += "tika-app-0.5-SNAPSHOT.jar -m "+fullPath+" | awk -F:" cmd += " 'BEGIN {print \"<cas:metadata xmlns:cas=" cmd += "\\\"http://oodt.jpl.nasa.gov/1.0/cas\\\";>\"}" cmd += " {print \"<keyval><key>\"$1\"</key><val>\"substr($2,2)\"" cmd += "</val></keyval>\"}' > "+fileName+".met" os.system(cmd) f = open(fileName+".met", 'a') f.write('<keyval><key>ProductType</key><val>'+productType) f.write('</val></keyval>\n<keyval><key>Filename</key><val>') f.write(fileName+'</val></keyval>\n'<keyval><key>FileLocation') f.write('</key><val>'+fileLocation+'</val></keyval>\n') f.write('</cas:metadata>') f.close() On 4/15/11 6:22 PM, "Davoodi, Faranak (388J)" <[email protected]> wrote: >Thanks Brian.
