Updating The Apache OpenNLP Community Apache NiFi Processor to Support Flow Files
In this new release, we add the ability to read content from the FlowFile and analyze that for Locations, Dates, Organizations and Names. We are using the Apache OpenNLP 1.5 Models that are available for download. These do a decent job. You can build new models as needed. I also changed it to output one attribute per type with a String list of locations, organizations, dates and names.
I put out a new release, built around Apache NiFi 1.6.0.
