 	* create tables
 
 ### BACKEND
-	* probably need a "batch" processing system that uses ionice to minimise load on mara
+	* need a "batch" processing system that uses ionice to minimise load on mara and is threaded and used DB to interact with gunicorn'd pa
+
+    DB tables to share between pa and pa_jobs:
+        create table pa_job_state ( state string, num_jobs_active integer, num_jobs_complete )
+        create table pa_jobs ( job_id, <...> )
+
+    pa_jobs (threaded python add separate from photoassistant)
+        takes over files.py
+        has ai.py
+        needs broad jobs to:
+            find files in {import_dir & storage_dir}
+            calc thumbs/hashes { " }
+            run AI against { " }
+            move files from import_dir to appropriate sub_dir in storage_dir (list will come from pa web)
+
+        to keep html easy, can keep routes:
+            /jobs/import/ -> importlog.html
+            /jobs/ai/ -> importlog.html???
+
+        but not sure if any job won't have passes, num files, etc.  BUT if it ever does this is how we deal with it
+
+        on start-up:
+            set state: initialising
+            get settings, if no import_dir -> set state: Configuration Needed
+            check DB for any files
+                -> if some, set state: awaiting jobs
+                -> if none, set state: Find Files (run that code)
+                    -> when job finished, then Import Files (import_dir only)
+                    -> when job finished, the set state: awating jobs
+
+
+        implications, pa_job needs to know if it depends on another, e.g. do find before import (in example above)
+        pa web needs to show status for the job engine IN YOUR FACE when not at awaiting jobs yet, afterwards, maybe a simple jobs(<badge>) that is clickable on the gui?

 ### UI
-	* use native file dialog box to set import_path in a "settings page"
-	* basic browse the import path
-	* some sort of log of import like:
-
-State: finding files / found X files / AI for <cam>
-Progress: overall # of passes
-Progress: X of Y files 
-History:
-    <time> finding files
-    <time> found X files
-    <time> getting thumbnails for files
-    <time>     X/10 of X
-    <time>     100% of all thumbs
-    <time> starting AI for <ref_img>
-    <time>     X/10 of X done - AI for <ref_img>
-    etc...
-
 
 ### AI
-	* store reference images
+	* store reference images (UI allows this now)
 	* check images
