+% Using the MasterKey Widget Set to embed metasearching functionality in any web-site

+Introduction
+------------
+
+There are lots of practical problems in building resource discovery
+solutions. One of the biggest, and most ubiquitous is incorporating
+metasearching functionality into existing web-sites -- for example,
+content-management systems, library catalogues or intranets. In
+general, even when access to metasearching is provided by simple
+web-services such as [Pazpar2](http://www.indexdata.com/pazpar2),
+integration work is seen as a major part of most projects.
+
+Index Data provides several different toolkits for communicating with
+its metasearching middleware, trading off varying degrees of
+flexibility against convenience:
+
+* libpz2.js -- a low-level JavaScript library for interrogating the
+ Service Proxy and Pazpar2. It allows the HTML/JavaScript programmer
+ to implement simple JavaScript functions to display facets, records,
+ etc.
+
+* masterkey-ui-core -- a higher-level, complex JavaScript library that
+ uses libpz2.js to provide the pieces needed for building a
+ full-featured JavaScript application.
+
+* MasterKey Demo UI -- an example of a searching application built on
+ top of masterkey-ui-core. Available as a public demo at
+ http://mk2.indexdata.com/
+
+* MKDru -- a toolkit for embedding MasterKey-like searching into
+ Drupal sites.
+
+All of these approaches require programming to a greater or lesser
+extent. Against this backdrop, we introduced MKWS (the MasterKey
+Widget Set) -- a set of simple, very high-level HTML+CSS+JavaScript
+components that can be incorporated into any web-site to provide
+MasterKey searching facilities. By placing `<div>`s with well-known
+identifiers in any HTML page, the various components of an application
+can be embedded: search-boxes, results areas, target information, etc.
+
+
+Simple Example
+--------------
+
+The following is a complete MKWS-based searching application:
+
+ <html>
+ <head>
+ <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
+ <title>MKWS demo client</title>
+ <link rel="stylesheet" href="http://mkws.indexdata.com/mkwsStyle.css" />
+ <script type="text/javascript" src="http://mkws.indexdata.com/mkws-complete.js"></script>
+ </head>
+ <body>
+ <div id="mkwsSwitch"></div>
+ <div id="mkwsLang"></div>
+ <div id="mkwsSearch"></div>
+ <div id="mkwsResults"></div>
+ <div id="mkwsTargets"></div>
+ <div id="mkwsStat"></div>
+ </body>
+ </html>
+
+More sophisticated applications will not simply place the `<div>`s
+together, but position them carefully within an existing page
+framework -- such as a Drupal template, an OPAC or a SharePoint page.
