Questions: Filemgr metadata ingest
All,
I am new to OODT. Just downloaded the software and installed it.
I am following "OODT Filemgr User Guide" to ingest files. (https://cwiki.apache.org/confluence/display/OODT/OODT+Filemgr+User+Guide)
Everything went well and I was able to ingest the blah.txt file successfully!
Now here comes my questions:
1. If I want to add some my own metadata fields in blah.txt.met, what would be the format?
2. In product-types.xml file, there is a tag called "metadata". Are these key/value pairs added to that relevant product type (such as GenericFile) as metadata fields?
3. Is there any tutorial that describes a metExtractor creation (either in Java or Python)?
Thanks,

Key/Multi-value of the form:
<cas:metadata>
<keyval>
<key>KeyName</key>
<val>val1</val>
<val>val2</val>
</keyval>
<—more —>
</cas:metadata>
See schema here:

Same as above, same format. These are also “ProductType” met fields
meaning they are true
(and don’t differ) for all products in the ProductType or dataset.
