+* Tasks for the =2010-02-campus-integration-reorg= branch
+
+  The goal of this branch is to reorganize and document the two major
+  integration points in Syrup: the library systems and the campus
+  information systems. Both of these integrations existed prior to the
+  branch, but were undocumented and messy.
+
+** The Evergreen-or-not question. 
+   - Prepare to sync with the =eg-schema-experiment= branch
+   - "in evergreen database" vs. "other database with OpenSRF calls"
+
+** Enumerate the ways that campus integration is currently used.
+   Put this in the campus-integration documentation.
+
+** A Library Integration module which is readable and documented
+   - integrate via local_settings.py
+   - Prepare to sync with the =eg-schema-experiment= branch
+
+** How much of the integration data belongs in the database?
+   Should the Django ADMINS list be pulled from the db? What about
+   Z39.50 targets? What are the deciding principles when figuring out
+   where to store config data?
+
+** Campus integration for departments.
+   - how to address the faculty/campus/dept/etc. hierarchy?
+   - list of departments
+   - look up department based on course-code
+   - instructors in a given department
+
+** question: Campus integration for terms?
+   Even just a "feed of terms you might not yet know about?"
+
+** question: when looking up membership info, always update membership table?
+   Should just asking an external campus system, 'What sections is
+   John in?' automatically add membership records for John, for
+   course-sites related to those sections? Should it also (only during
+   the active period of a term) drop John from current sections that
+   he's no longer part of?

-# Validation and lookup of course codes.
-
-# This modules specifies an "course-code interface" and a null
-# implementation of that interface. If your local system has rules for
-# valid course codes, and a mechanism for looking up details of these
-# codes, you can implement the interface according to your local
-# rules.
-
-
-# ------------------------------------------------------------
-# Overview and definitions
-
-# A course code identifies a specific course offering. Course codes
-# map 1:N onto formal course titles: by looking up a code, we can
-# derive a formal title (in theory, though it may not be possible for
-# external reasons).
-
-# A course code is insufficient to specify a class list: we need a
-# course section for that. A section ties a course code and term to an
-# instructor(s) and a list of students.
-
-# Course codes may have cross-listings, i.e., other codes which refer
-# to the same course, but which appear under a different department
-# for various academic purposes. In our system, we make no attempt to
-# subordinate cross-listings to a "primary" course code.
-
-
-#------------------------------------------------------------
-# Notes on the interface
-#
-# The `course_code_is_valid` function will be used ONLY if
-# course_code_list() returns None (it is a null implementation). If a
-# course-list is available, the system will use a membership test for
-# course-code validity.
-#
-# `course_code_lookup_title` will be used ONLY if `course_code_list`
-# is implemented.
-#
-#
-# "types" of the interface members
-#
-# course_code_is_valid       (string) --> boolean.
-# course_code_example        : a string constant.
-# course_code_list           () --> list of strings
-# course_code_lookup_title   (string) --> string, or None.
-# course_code_cross_listings (string) --> list of strings
-#
-# For each member, you MUST provide either a valid implementation, or
-# set the member to None. See the null implementation below.
-

-# Operations on course-section identifiers
-
-# A course section is an instance of a course offered in a term. 
-
-# A section is specified by a 'section-id', a 3-tuple (course-code,
-# term, section-code), where section-code is usually a short
-# identifier (e.g., "1" representing "section 1 in this term"). Note
-# that multiple sections of the same course are possible in a given
-# term.
-
-# Within the reserves system, a course-site can be associated with
-# zero or more sections, granting access to students in those
-# sections. We need two representations of a section-id.
-
-# The section_tuple_delimiter must be a string which will never appear
-# in a course-code, term, or section-code in your database. It may be
-# a nonprintable character (e.g. NUL or CR). It is used to delimit
-# parts of the tuples in a course's database record.
-
-#------------------------------------------------------------
-# Notes on the interface
-#
-# 'sections_taught_by(username)' returns a set of sections for which
-# username is an instructor. It is acceptable if 'sections_taught_by'
-# only returns current and future sections: historical information is
-# not required by the reserves system.
-#
-# It is expected that the reserves system will be able to resolve any
-# usernames into user records. If there are students on a section-list
-# which do not resolve into user accounts, they will probably be
-# ignored and will not get access to their course sites. So if you're
-# updating your users and sections in a batch-run, you might want to
-# update your users first.
-#
-#------------------------------------------------------------
-# Implementations
-
-# The reserves system will work with a null-implementation of the
-# course-section interface, but tasks related to course-sections will
-# be unavailable.
