+== Loading images on the server ==
+
+We'll develop a script '''load_images''' that takes the above info
+and loads it into the Bossa database.
+Each run of this script produces a "batch" of jobs
+that can be managed as a unit (see below).
+Initially the state of the batch is "pending",
+meaning that it is not available to volunteers.
+
 == Volunteer levels ==
+
+There will be three levels of participation:
+ Beginning:: Identify bones, no classification.  Intended for elementary school kids.
+ Intermediate:: Distinguish Primate/Nonprimate, and Tooth/Skull/Other.
+ Advanced:: Distinguish ~10 taxa and ~5 bone types.
 
 == Training course ==
 
+We'll need to develop training courses (probably using Bolt)
+for each volunteer level.
+A given course will contain:
+
+ * several examples (different ages, lighting conditions) of each type of object to be identified, some negatives, and some images that look like positives but are negative.
+ * a test consisting of some number of positive and negative examples
+
 == Volunteer experience ==
+
+Each image will initially be shown in a medium-res (1024x768) form.
+It will have a control area that remains fixed in the UL corner, even if the image scrolls.
+The control area includes:
+ * a "Done" button 
+ * a "Magnify" or "Shrink" button. This toggles between the medium-res and hi-res (3Kx2K) image.
+ * a "Rotate" button that rotates the image 90 deg.
+
+To identify a feature, the user clicks on the image.
+This pops up a window in which they select (from menus) that taxa and bone type,
+and can type an optional comment.
+
+After every N images (N=1?) the volunteer is shown a feedback page (see below).
 
 == Feedback page ==
 
+This page is intended to give volunteers feedback on their efforts,
+and to encourage them to continue.
+Possible contents:
+
+ * thumbnails of recent jobs, with links so that they can see how other people annotated the same image.
+ * links to message boards
+ * "who's online now", with ability to send instant messages
+ * this users's message inbox
+
 == Calibration images ==
 
+We may want to use "calibration images", i.e. images for which the correct annotation is known,
+for two reasons:
+
+ * to increase the fraction of images that contain something
+ * to improve our assessment of volunteer error rates
+
 == Scientist interfaces ==
+
+Scientists will interact through a web-based interface.
+The top-level page will show a list of batches,
+with their times, names, spatial extent, and status
+(Pending, In Progress, Completed).
+For a given batch, the scientist can:
+
+ * Change the status of the batch
+ * View a map in which the images appear as small rectangles, with color coding showing which have been processed by volunteers, and how many features were found.  Clicking on a rectangle goes to a page showing the instances of the job, allowing the scientist to view and compare the results, to select a "best" answer, and to add their own annotations.
+ * View a textual list of images, ordered by decreasing number of features found.
