That's not necessarily bad: sometimes a piece of software can be done, or nearly so.

Yup but a project like this would have an empty issue tracker this one not so much ;)

(which doesn't mean that it's a bad project or that I wont use it. it means that I will probably start to work on it)

There actually was some activity in three different branches in january: https://github.com/kskyten/noteshrink/network

Yeah on a branch of a fork.

I have made some progress on this as my home project using same compression and scan. I call it DFA - digital file analytics where data/images/scanned documents are sent remotely using Kafka to Hadoop and then run OCR to extract text and compression. If the document is more then 10MB go to HBase otherwise HDFS. Near real-time streaming using Spark and Flink is done too. Visualization using Banana dashboard is not so cool as it shows word counts, storage location, images and tags. Analytics on top of extracted data using ML would like to do next.

Could you expand on your archive+ocr? I long wanted to start doing something like this, but never got to. I guess reading others' experience can be useful.
