Using Apache Nifi I'd like to process a zip which contains a category.json file and a number of data files as illustrated.

```
somefile.zip
├──category.json
├──datafile-1
├──datafile-2
├──...
├──datafile-n

```

Example category.json

```
{
  "category": "history",
  "rating" : 5 
}

```

What I'd like to do is unpack the files and apply the category.json data as attributes to each datafile. 

What would be the best way to handle this problem?
