+### Please describe the problem.
+
+While running `git-annex metadata --batch --json`, repeatedly assigning a field to the same value in the same run (with different values in between the assignments of the same value) causes a value to get stuck.
+
+### What steps will reproduce the problem?
+
+    $ touch test.txt
+    $ git annex add
+    $ git-annex metadata --batch --json
+    {"file":"test.txt","fields":{"f":["a"]}}
+    # prints { ... "f":["a"] ... }
+    {"file":"test.txt","fields":{"f":["b"]}}
+    # prints { ... "f":["b"] ... }
+    {"file":"test.txt","fields":{"f":["c"]}}
+    # prints { ... "f":["c"] ... }
+    {"file":"test.txt","fields":{"f":["a"]}}
+    # prints { ... "f":["a", "c"] ... }
+    {"file":"test.txt","fields":{"f":["b"]}}
+    # prints { ... "f":["c"] ... }

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+I love the metadata functionality so much that I wrote [[tips/a_gui_for_metadata_operations]] and discovered this bug.
+Metadata driven views are awesome (but I don't like the entire folder hierarchy being appended to the filename).
+I haven't used the other commands much since I have not yet organized most of my stuff (and their naively copy-pasted backups), but I am glad I discovered git-annex before I began organizing.
