+% An embryonic MasterKey Widget Set
+% Mike Taylor; Wolfram Schneider
+% 10 July 2013
+
+
+This directory contains an embryonic MasterKey Widget Set. The initial
+version was based on the "jsdemo" application distributed with
+pazpar2, but it is now far removed from those beginnnings.
+
+
+How this works
+--------------
+
+The goal is to make it that as much of the searching functionality as
+possible is hosted on
+ <http://mkws.indexdata.com/>
+so that very simple websites such as
+ <http://example.indexdata.com/>
+can have MasterKey searching with minimal effort.
+
+The following files are hosted on mkws.indexdata.com:
+
+* `mkws.js`
+* `mkwsStyle.css`
+* `/libjs-pz2/pz2api.1.js`
+
+The following files make up an application:
+
+* `index.html`
+* `favicon.ico` [_optional_]
+* `robots.txt` [_optional_]
+
+
+Configuring a client
+--------------------
+
+The application's HTML must contains the following elements as well as
+whatever makes up the application itself:
+
+Prerequisites:
+ <link rel="stylesheet" href="mkwsStyle.css" />
+ <script type="text/javascript">
+ var mkws_config = { };
+ </script>
+ <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>
+ <script type="text/javascript" src="/libjs-pz2/pz2api.1.js"></script>
+ <script type="text/javascript" src="mkws.js"></script>
+(Yes, we're using JQuery. We use it only in the most trivial ways, and
+could probably get rid of it without too much pain. I'd like to have
+mkws.js automatically pull in pz2api.1.js, too, so you don't need to
+do so many things, but that's not quite trivial.)
+
+Then the following special <div>s can be added (with no content), and
+will be filled in by MKWS:
+ <div id="mkwsSwitch"></div> -- switch between record and target views
+ <div id="mkwsLang"></div> -- switch between English, Danish and German
+ <div id="mkwsSearch"></div> -- search box and button
+ <div id="mkwsResults"></div> -- result list, including pager/sorting
+ <div id="mkwsTargets"></div> -- target list, including status
+ <div id="mkwsStat"></div> -- summary statistics
+
+At present, MKWS will not work correctly if any of these is
+missing. One of the TODOs is to fix it so that it doesn't try to use
+whatever is not there, and just uses what is.
+
+
+You can configure and control the client with the JavaScript mkws_config object.
+
+Here is an example of all possible options
+ <script type="text/javascript">
+ var mkws_config = {
+ use_service_proxy: true, /* true, flase: use service proxy instead pazpar2 */
+ switch_menu: true, /* true, false: show/hide Records|Targets menu */
+ lang_menu: true, /* true, false: show/hide language menu */
+ sort_menu: true, /* true, false: show/hide sort menu */
+ perpage_menu: true, /* true, false: show/hide perpage menu */
+ lang_display: ["en", "de", "da"], /* display languages links for given
+ languages, [] for all */
+ facets: ["sources", "subjects", "authors"], /* display facets, in this order, [] for none */
+ sort_default: "relevance", /* "relevance", "title:1", "date:0", "date:1" */
+ query_width: 50, /* 5..50 */
+ perpage_default: 20, /* 10, 20, 30, 50 */
+ lang: "en", /* "en", "de", "da" */
+ debug: 0, /* debug level for development: 0..2 */
+
+ responsive_design: false /* true, false: resize for smaller mobile devices */
+ pazpar2_url: "/pazpar2/search.pz2", /* URL */
+ service_proxy_url: "/service-proxy/", /* URL */
+ service_proxy_auth: "/service-proxy-auth", /* URL */
+ };
+ </script>
+
+Note: the mkws_config object which must be loaded before the mkws.js and pz2api.js files.
+
+
+jQuery plugin
+------------------
+
+The jQuery plugin version, consisting of a single line of JavaScript code
+
+ <script>jQuery.pazpar2();</script>
+
+put the code in your page at the position where the metasearch should occours.
+
+Here is an example of all possible options
+
+ jQuery.pazpar2({"layout": "popup", /* "table", "div", "popup", default is table */
+ "id_button": "input#mkwsButton", /* submit button id in search field */
+ "id_popup": "#mkwsPopup", /* interal id of popup window */
+ "width": 880, /* popup width, should be at least 800 */
+ "height": 760 /* popup height, should be at least 600 */
+ });
+
+
+Supported Browsers
+------------------
+
+Any modern HTML5 browser will work fine. JavaScript must be enabled.
+
+* IE8 or later
+* Firefox 17 or later
+* Google Chrome 27 or later
+* Safari 6 or later
+* Opera 12 or later
+* iOS 6.x (iPhone, iPad)
+* Android 4.x
+
+Not supported: IE6, IE7
+
+New Features since jsdemo
+--------------------------
+- multilinguality: English (default), Danish, German
+- depends on the new pazpar2 JS library libjs-pz2/pz2api.1.js
+ which will make the development of pazpar2 plugins faster and
+ easier to share code between projects
+- supports basic pazpar2 and service-proxy requests
+- simplified HTML
+- the search page is fully configurable by a JSON object
+
+
+What next?
+----------
+
+Main areas of work:
+* Make MKWS robust to missing widgets
+* Clean up the code
