<h1>Terminology</h1>

<p>
Ricardo terminology follows.

<h2>Application</h2>

An Application is a programme that does something.  For example,

<ul><li>
    <b>WebFunds</b> is a user client that can hold different
    <a href="#wallet">wallets</a>,
    and can use the payment technologies within in a sensible fashion.

  </li><p></p><li>
    <b>Teller</b> is a merchant application that can receive
    requests to deposit incoming payments and requests to write outgoing
    payments.  It only works with one wallet, being the SOX Wallet.

  </li><p></p><li>
    <b>CashBox</b> is an <a href="http://www.intertrader.com/">Intertrader</a>
    Payments management system that
    works with many wallets (which they call Instruments).  It
    has a client side downloadable application and a merchant
    side payments manager.
</li></ul>

<h2><a name="wallet">Wallet</a></h2>

<p>
A Wallet is a module offering payments of a particular type
and technology.  E.g., SOX wallet can do SOX payments and deposits.

<p>
There are two other wallets in preparation for WebFunds:  a DBS wallet
using Wagner blinding, and a trading wallet.  Both of these are
likely to be extensions of the SOX Wallet.

<p>
Each Wallet conforms to the interface located in
<tt>webfunds/client/WalletInterface.java</tt>.
In the case of the SOX wallet, the module is at
<tt>webfunds/client/sox/SOXWallet.java</tt>.

<p>
The SOX Wallet will probably change to insert a GUI-free wallet 
(and internal interface) in something
like <tt>webfunds/soxwallet</tt> or <tt>webfunds/sox/wallet</tt>.
Then, the original SOXWallet will add the GUI stuff to the new
GUI-free wallet.  This is a precondition for non-GUI exporters
working with SOX (merchant applications like Teller and CashBox).

<h2>Item, Contract, Instrument</h2>
These terms may sometimes mean the same thing:

<p>
<ul><li>
    <b>item</b> is a SOX value identifier (byte array), literally, the
    field in the SOX payment or the SOX sub account that identifies
    value type.

  </li><p></p><li>
    <b>contract</b> is a Ricardian contract, the hash of which is used as
    an item (SHA1).  WebFunds assumes that all value, regardless of the
    wallet, is identified by a Ricardian contract.  So, if we were to
    add a form of value that was distinct, say, smart card money, then
    we may have to write some contract wrappers to keep WebFunds happy
    with its assumption.

  </li><p></p><li>
    <b>instrument</b> is a financially traded ricardian contract, as opposed
    to a contract that is not traded, or outside the trading context.

</li></ul>

<p>
So, DigiGold might be an instrument, a contract, and an item,
depending on the context..

<h2>Some Intertrader Terminology</h2>

We have some words that are swapped with Intertrader usage.
