Hi All,
I am trying to use the MetadataBasedFileVersioner to store my files in a
subdirectory of the data/archive folder based on the values of two metadata
elements. Has anyone does this before, and if so, can you give me some hints.
My files need to be organized in subdirectories by year and day of year. So,
lets say the file name is 'myfile', the year is 2014, and the doy of year is
002. Then, the end result that I am looking for is to have the final location
of my file be: 'data/archive/ops/eng/2014/002/myfile.
However, in my log file, the INFO messages indicate that the generated final
location reference is 'data/archive/ops/eng/myfile'. And it doesn't include
the year and day of year at all. And the incorrect location leads to other
errors. So I want to solve this one first. Has anyone tried to do something
like this before?
Here is what I have done so far:
Added two new elements to the .met file 'YearDir' and 'DoyDir'.
Added these new elements to the elements.xml file.
Added these new elements to the product in the product-type-element-map.xml
file.
And, I have made changes to the product-types.xml file, but here's where I am
not sure I've done this properly.
Here's what product type definition looks like:
<type id="urn:oodt:EngineeringFile" name="EngineeringFile">
<repository path="file://[OODT_HOME]/data/archive/ops/eng"/>
<versioner
class="org.apache.oodt.cas.filemgr.versioning.MetadataBasedFileVersioner">
<property name="filePathSpec" value="/[YearDir]/[DoyDir]/" />
</versioner>
<description>The default product type for any kind of file.</description>
<metExtractors>
<extractor
class="org.apache.oodt.cas.filemgr.metadata.extractors.CoreMetExtractor">
<configuration>
<!-- you can optionally include the envReplace tag to turn on/off
environment var replacement -->
<property name="nsAware" value="true" />
<property name="elementNs" value="CAS" />
<property name="elements"
value="ProductReceivedTime,ProductName,ProductId" />
</configuration>
</extractor>
</metExtractors>
<metadata/>
</type>
Thanks in advance for any help or ideas you might have!
