Tyler Palsulich commented on OODT-826:
--------------------------------------
Hi Val. Awesome! Can you upload a patch? You can do that by running {{svn
status}}, looking at the files with {{?}} by them which you need for this issue
(like the new class), running {{svn add \[file\]}} for each of those, then run
{{svn diff > OODT-826.lasname.patch}}. Then upload that file to this issue
(More > Attache Files) or on reviews.apache.org.
If there are any files you've changed that aren't relevant to this issue, you
can run {{svn revert \[file\]}} to _revert_ all changes to that file (make sure
you really don't want those changes! You might want to copy the file somewhere,
first (or create a backup with another {{svn diff > backup.file}})).
I'm happy to help if you run into any issues.
> Add the capability to check external preconditions before ingesting a file.

> 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.
