Cleaning jewlery

I have a lot of silver jewelery that has tarnished over the years. I have been looking for a way to clean it. Here is what I have found:

For silver jewelry take a piece of foil, hot water and baking soda. Place jewelry in it for a few minutes and it should be as good as new.

Also, I found these instructions from Zales really helpful (http://www.zales.com/jewelry101/index.jsp?page=care_Cleaning). I was considering buying an ultrasonic jewelry cleaner, but after reading this information decided against it:
Cleaning
A regular professional cleaning is a good idea. Not only does it keep your jewelry looking its best, it also ensures that a trained professional takes a look at it at least once a year, allowing for the earliest possible detection of wear or damage. Between professional cleanings, however, there are some things you can do to keep your jewelry clean.
Diamonds
For diamonds, use a soft-bristled non-metallic brush and a mild ammonia and water solution. Gently scrub away any grime, especially around the prongs or setting where buildup is likely. Even a clean looking diamond often has a thin layer of skin oil and will shine better after a cleaning. Avoid touching the diamond as much as possible.
Gemstones
Cleaning gemstones is easy. Simply soak the piece in a bowl of warm, soapy water for several minutes and then use a soft, non-metallic brush to remove any grime. If you use a jewelry cleanser, make sure it is non-abrasive. Don’t use harsh chemical cleaners, and don’t clean the item in the sink too often it ends up down the drainpipe. Also keep in mind that some gemstones may have been treated or enhanced by heating, oiling, irradiation or diffusion. Heated and irradiated stones generally don’t require special care when cleaning, but diffused stones could become lighter if scrubbed too hard. Also, the oil on an emerald can be stripped away by cleaning, making the emerald change appearance. If this happens, simply bring it to your jeweler for re-oiling.
Pearls
Pearls are beautiful. Unfortunately, the layers of nacre of which a pearl is made are very soft by jewelry standards and easily damaged. Since it is an organic compound, pearls also are easily dulled or even eaten away by chemicals and alcohol. Wash cultured pearls in very mild, soapy water and nothing else. It's also a good idea to bring your cultured pearls in for restringing every couple of years, especially if you wear them often.
Metals
For mountings, you can use rubbing alcohol to dissolve some of the stickier grime. However, don’t use alcohol on any kind of pearl jewelry. Soap and water and a soft brush will take care of most of your cleaning needs. Make sure the brush is VERY soft when used on metal, especially gold, which can be scratched relatively easily. Use a soft cloth that won’t leave fuzz or threads behind to dry and buff your jewelry once it's cleaned.
Ultrasonic Cleaners
Ultrasonic cleaners are machines that clean jewelry by bombarding them with sound waves. This vibration shakes off dirt, but the vibrations can also cause serious damage. The inclusions in gemstones, especially brittle stones like emeralds, can be greatly enlarged by the shaking, making the stones less attractive and even less valuable. Soft gems like pearls should never be put in an ultrasonic cleaner. Because of the risk, we recommend against using the ultrasonic cleaners now available to consumers unless your jeweler specifically says it won’t cause any damage.

SCORM & Section 508

SCORM
http://en.wikipedia.org/wiki/Sharable_Content_Object_Reference_Model
Sharable Content Object Reference Model (SCORM) is a collection of standards and specifications for web-based e-learning. It defines communications between client side content and a host system called the run-time environment, which is commonly supported by a learning management system. SCORM also defines how content may be packaged into a transferable ZIP file called "Package Interchange Format".

Section 508
http://www.section508.gov/index.cfm
In 1998, Congress amended the Rehabilitation Act of 1973 to require Federal agencies to make their electronic and information technology (EIT) accessible to people with disabilities. Inaccessible technology interferes with an ability to obtain and use information quickly and easily. Section 508 was enacted to eliminate barriers in information technology, open new opportunities for people with disabilities, and encourage development of technologies that will help achieve these goals. The law applies to all Federal agencies when they develop, procure, maintain, or use electronic and information technology. Under Section 508 (29 U.S.C. ‘794 d), agencies must give disabled employees and members of the public access to information that is comparable to access available to others.
