Due to having a problem with my eyes, I was hesitant to go through this documentation. I finally endured the pain(literally) and went through it. Apparently those lines are for running that mp3 java code. Please answer my question below:
1. The python extractor I have generates the file bellow: <?xml version="1.0" encoding="UTF-8"?> <cas:metadata xmlns:cas="http://oodt.jpl.nasa.gov/1.0/cas";> <keyval> <key>MasterQualityFlag</key> <val>Good</val> </keyval> <keyval> <key>ProcessingLevel</key> <val>L1</val> </keyval> </cas:metadata> I do: chmod +x script.py however, it when I try to run it as ./script.py. It wouldn't and complains about : ./CARVE_KML_Extractor.py: line 20: import: command not found ./CARVE_KML_Extractor.py: line 21: import: command not found ./CARVE_KML_Extractor.py: line 22: import: command not found from: can't read /var/mail/xml.dom.minidom However if I simply run like: python script.py [inputProduct][outputdir], it works fine. Do I need to be able to run that python script like ./script.py to be able to use it as an metadata extractor. Cameron, since this is your code. Would you help me and see what you can do to make it run like: ./script.py. 2. I noticed that in the link http://oodt.apache.org/components/maven/curator/user/basic.html, the python code you just specify the input file: ./mp3PythonExtractor.py /usr/local/staging/products/mp3/Bach-SuiteNo2.mp3. Since I need to integrate this to my cas-pge crawler, and it needs to perform this metadata extraction on the product just generated, what exactly I need to pass as argument in terms of [inputFile][outmetpath]?
