| − | == National Problem Library (NPL) == |
||
| − | |||
| − | The National Problem Library contains problems from several of the File Based Problem Libraries, including all of the problems from the Arizona State, Rochester, Cal State Long Beach, University of Virginia libraries. It also contains most, if not all, of the problems from Union College, College of New Jersey, Dartmouth, Ohio State, Northern Arizona University, and Indiana University. |
||
| − | |||
| − | In addition to merging these problem collections into a single collection, WeBWorK provides a different interface to these problems. Problems in the NPL are marked internally with metadata, and instructors can search for problems on the basis of this data. This mechanism is built into WeBWorK's library browser. In particular, one can search hierarchically by course, chapter, section. To a limited extent, problems have been indexed against sections of textbooks in which case an instructor can also search for problems on that basis. WeBWorK stores this information in a database, so part of the installation involves loading metadata into the database. |
||
| − | |||
| − | === Obtaining the NPL === |
||
| − | |||
| − | First, make sure you have an <code>/opt/webwork/libraries</code> directory: |
||
| − | |||
| − | $ mkdir -p /opt/webwork/libraries |
||
| − | |||
| − | The database problem library can be downloaded from the ASU CVS repository. |
||
| − | |||
| − | $ cd /opt/webwork/libraries |
||
| − | $ cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/asu co database_problems |
||
| − | |||
| − | If you are running WeBWorK 2.3.x, you must create a <code>ProblemLibrary</code> database on your MySQL server. (<strong>*****</strong> represents the MySQL root password.) |
||
| − | |||
| − | $ mysql -u root |
||
| − | Password: ***** |
||
| − | > CREATE DATABASE ProblemLibrary; |
||
| − | > GRANT SELECT on ProblemLibrary.* TO webworkWrite@localhost; |
||
| − | > quit |
||
| − | Bye. |
||
| − | $ |
||
| − | |||
| − | If you are running WeBWorK 2.4.x, this is not necessary as the NPL indexes are stored within the main <code>webwork</code> database. |
||
| − | |||
| − | Configure WeBWorK to access the problem library. The settings are in <code>global.conf</code>: |
||
| − | |||
| − | '''''For WeBWorK 2.3.x:''''' |
||
| − | |||
| − | {| border="1" |
||
| − | |- |
||
| − | | '''variable''' || '''description''' |
||
| − | |- |
||
| − | | <code>$problemLibrary{root}</code> || Path to <code>database_problems</code> directory. Should be <code>/opt/webwork/libraries/database_problems</code>. |
||
| − | |- |
||
| − | | <code>$problemLibrary{version}</code> || Version of the problem library database. Should be =2=. |
||
| − | |- |
||
| − | | <code>$problemLibrary{sourceSQL}</code> || Name of the database. Should be <code>ProblemLibrary</code>. |
||
| − | |- |
||
| − | | <code>$problemLibrary{userSQL}</code> || Username to use when connecting to the database. Can usually be left as <code>$database_username</code>. |
||
| − | |- |
||
| − | | <code>$problemLibrary{passwordSQL}</code> || Password to use when connecting to the database. Can usually be left as <code>$database_password</code>. |
||
| − | |} |
||
| − | |||
| − | '''''For WeBWorK 2.4.x''''' |
||
| − | |||
| − | {| border="1" |
||
| − | |- |
||
| − | | '''variable''' || '''description''' |
||
| − | |- |
||
| − | | <code>$problemLibrary{root}</code> || Path to <code>database_problems</code> directory. Should be <code>/opt/webwork/libraries/database_problems</code>. |
||
| − | |- |
||
| − | | <code>$problemLibrary{version}</code> || Version of the problem library database. Should be =2=. |
||
| − | |- |
||
| − | | <code>$problemLibrary_db{dbsource}</code> || Name of the database. Can usually be left as $database_dsn. |
||
| − | |- |
||
| − | | <code>$problemLibrary_db{user}</code> || Username to use when connecting to the database. Can usually be left as <code>$database_username</code>. |
||
| − | |- |
||
| − | | <code>$problemLibrary_db{passwd}</code> || Password to use when connecting to the database. Can usually be left as <code>$database_password</code>. |
||
| − | |} |
||
| − | |||
| − | Finally, populate the database: |
||
| − | |||
| − | '''''For WeBWorK 2.3.x:''''' |
||
| − | |||
| − | Run the <code>loadDB2</code> script to populate the database. This script must be run from the <code>database_problems</code> directory. |
||
| − | |||
| − | $ cd /opt/webwork/libraries/database_problems |
||
| − | $ ./loadDB2 |
||
| − | What is the root password for mysql? ***** |
||
| − | Mysql database reinitialized |
||

||
| − | $ |
||
| − | |||
| − | '''''For WeBWorK 2.4.x:''''' |
||
| − | |||
| − | Run the NPL-update script to populate the database. This script is located in the <code>webwork2/bin</code> directory and may be invoked from anywhere. |
||
| − | |||
| − | $ /opt/webwork/webwork2/bin/NPL-update |
||
| − | Mysql database reinitialized. |
||
| − | Reading in textbook data. |
||
| − | Converting data from tagged pgfiles into mysql. |
||
| − | Number of files processed: |

| − | 100 200 300 400 500 600 700 800 900 1000 |
||
| − | ... |
||
| − | Done. |
||
| − | $ |
||
| − | |||
| − | There is no need to add symlinks to course <code>templates</code> directory, as is necessary with file based Problem Libraries. It is done automatically. |
||
| − | |||
| − | === Browsing the NPL === |
||
| − | |||
| − | Log into a WeBWorK course and select '''Library Browser''' from the links menu. On the resulting screen, click the '''Problem Library''' button. |
||
| − | |||
| − | === Updating the NPL === |
||
| − | |||
| − | The CVS repository for the NPL is updated as problems are added, additional metadata is added, or problem bugs are fixed. So, it is a good idea to update your copy of the NPL periodically, say once per semester. |
||
| − | |||
| − | To update, run the <code>cvs update</code> command to download the latest versions from our server. Then, re-run <code>loadDB2</code> (WeBWorK 2.3.x) or NPL-update (WeBWorK 2.4.x). |
||
| − | |||
| − | $ cd /opt/webwork/libraries/database_problems |
||
| − | $ cvs -q update -dPA |

File Based Problem Libraries
These libraries consist of a directory tree organized roughly by the chapters of a canonical calculus book (or in some cases a canonical text for another subject). There is no database index of tagged metadata. It is envisioned that the material in these libraries will eventually be given metadata, checked for errors and duplicates and folded into the NPL.
- The "(CVS)" links for each library allow you to inspect the contents of the library over the web.
- See CVS Access to Problem Libraries for instructions on downloading the contents of these libraries via CVS.
- You can find tarballs of each libraries at http://webhost.math.rochester.edu/webworkdocs/librarytarballs.
Arizona State University Math Problem Library
This problem library is now empty. All of the problems have been moved into the National Problem Library.
The College of New Jersey Math Problem Library
The College of New Jersey (TCNJ) makes a large number of linear algebra
problems available in this collection. Please send links of any problems that don't
work to Tom Hagedorn, hagedorn at tcnj.edu. (CVS)
To check out this library:
cvs -d :pserver:anoncvs@cvs.webwork.rochester.edu:/webwork/cvs/tcnj co tcnj_problib

The Union College Math Problem Library should now be fully funcitonal. A few of the problems may not work as advertised, since they may have trouble finding the links to auxiliary materials, such as external graphs.
Davide Cervones and Kathryn Leash are principally responsible for designing these problems. The level set and 3d problems are particularly nice!!
Please send links of any problems that don't work to gage at math.rochester.edu or dpvc at union.edu or better yet enter them into the WeBWorK bugzilla via the "report problem bugs" on the PG editor page. (CVS)
