------------------------------------

             Summary:  Add the capability to check external preconditions before ingesting a file.
                 Key: OODT-826
                 URL: https://issues.apache.org/jira/browse/OODT-826
             Project: OODT
          Issue Type: New Feature
          Components: crawler, metadata container, radix
    Affects Versions: 0.8.1
            Reporter: Valerie Mallder
            Assignee: Valerie Mallder
            Priority: Minor
             Fix For: 0.9


I created an ExternPreconditionComparator class.  I needed one and it seemed like a logical thing to do since there are already several  'Extern'-type classes in the OODT. Here are the details:

New ExternPreconditionComparator class in:
oodt/trunk
/metadata/src/main/java/org/apache/oodt/cas/metadata/preconditions/ExternPreconditionComparator.java  

New example external script in:
oodt/trunk /crawler/src/main/resources/extern-scripts/check-data-file-complete.pl

Modify precondition-beans.xml  in oodt/trunk /crawler/src/main/resources/ and 
oodt/trunk/mvn/archetypes/radix/src/main/resources/archetype-resources/cra
wler/src/main/resources/policy/  to add example precondition beans for the ExternPreconditionComparator class.
