21 <title>Automatic Recording for KiSS Hard Disk Recorders</title>
25 KiSS makes regular updates to their site that sometimes require adaptations
26 to the crawler. If it stops working, check out the most recent version here.

29 <title>Changelog</title>
32 <title>7 September 2006</title>
34 <li>KiSS modified the login procedure. It is now working again.</li>
38 <title>31 August 2006</title>
40 <li>Added windows bat file for running the crawler under windows.
41 Very add-hoc, will be generalized. </li>
45 <title>24 August 2006</title>
47 <li>The crawler now uses desktop login for crawling. Also, it is much more efficient since
48 it no longer needs to crawl the individual programs. This is because the channel page
49 includes descriptions of programs in javascript popups which can be used by the crawler.
50 The result is a significant reduction of the load on the KiSS EPG site. Also, the delay
51 between requests has been increased to further reduce load on the KiSS EPG site. </li>
53 The crawler now crawls programs for tomorrow instead of for today.
56 The web based crawler is configured to run only between 7pm and 12pm. It used to run at
63 <title>13-20 August 2006</title>
65 There were several changes to the login procedure, requiring modifications to the crawler.
68 <li>The crawler now uses the 'Referer' header field correctly at login.</li>
69 <li>KiSS now uses hidden form fields in their login process which are now also handled correctly by the
74 <section id="overview">
75 <title>Overview</title>
78 In 2005, <a href="site:links/kiss">KiSS</a> introduced the ability
79 to schedule recordings on KiSS hard disk recorder (such as the
80 DP-558) through a web site on the internet. When a new recording is
81 scheduled through the web site, the KiSS recorder finds out about
82 this new recording by polling a server on the internet.
83 This is a really cool feature since it basically allows programming
84 the recorder when away from home.
87 After using this feature for some time now, I started noticing regular
88 patterns. Often you are looking for the same programs and for certain
89 types of programs. So, wouldn't it be nice to have a program
90 do this work for you and automatically record programs and notify you
91 of possibly interesting ones?
94 This is where the KiSS crawler comes in. This is a simple crawler which
95 logs on to the KiSS electronic programme guide web site and gets
96 programme information from there. Then based on that it automatically
97 records programs for you or sends notifications about interesting ones.
100 In its current version, the crawler can be used in two ways:
103 <li><strong>standalone program</strong>: A standalone program run as a scheduled task.</li>
104 <li><strong>web application</strong>: A web application running on a java
105 application server. With this type of use, the crawler also features an automatic retry
106 mechanism in case of failures, as well as a simple web interface. </li>
111 <title>Downloading</title>
114 At this moment, no formal releases have been made and only the latest
115 version can be downloaded.
118 The easy way to start is the
119 <a href="installs/crawler/target/wamblee-crawler-0.2-SNAPSHOT-kissbin.zip">standalone program binary version</a>
120 or using the <a href="installs/crawler/kissweb/target/wamblee-crawler-kissweb.war">web
124 The latest source can be obtained from subversion with the
125 URL <code>https://wamblee.org/svn/public/utils</code>. The subversion
126 repository allows read-only access to anyone.
129 The application was developed and tested on SuSE linux 9.1 with JBoss 4.0.2 application
130 server (only required for the web application). It requires at least a Java Virtual Machine
131 1.5 or greater to run.
136 <title>Configuring the crawler</title>
139 The crawler comes with three configuration files:
142 <li><code>crawler.xml</code>: basic crawler configuration
143 tailored to the KiSS electronic programme guide.</li>
144 <li><code>programs.xml</code>: containing a description of which
145 programs must be recorded and which programs are interesting.</li>
146 <li><code>org.wamblee.crawler.properties</code>: Containing a configuration </li>
149 For the standalone program, all configuration files are in the <code>conf</code> directory.
150 For the web application, the properties files is located in the <code>WEB-INF/classes</code>
151 directory of the web application, and <code>crawler.xml</code> and <code>programs.xml</code>
152 are located outside of the web application at a location configured in the properties file.
157 <title>Crawler configuration <code>crawler.xml</code></title>
160 First of all, copy the <code>config.xml.example</code> file
161 to <code>config.xml</code>. After that, edit the first entry of
162 that file and replace <code>user</code> and <code>passwd</code>
163 with your personal user id and password for the KiSS Electronic
169 <title>Program configuration</title>
171 Interesting TV shows are described using <code>program</code>
172 elements. Each <code>program</code> element contains
173 one or more <code>match</code> elements that describe
174 a condition that the interesting program must match.
177 Matching can be done on the following properties of a program:
180 <tr><th>Field name</th>
181 <th>Description</th></tr>
184 <td>Program name</td>
188 <td>Program description</td>
192 <td>Channel name</td>
196 <td>Keywords/classification of the program.</td>
200 The field to match is specified using the <code>field</code>
201 attribute of the <code>match</code> element. If no field name
202 is specified then the program name is matched. Matching is done
203 by converting the field value to lowercase and then doing a
204 perl-like regular expression match of the provided value. As a
205 result, the content of the match element should be specified in
206 lower case otherwise the pattern will never match.
207 If multiple <code>match</code> elements are specified for a
208 given <code>program</code> element, then all matches must
209 apply for a program to be interesting.
217 <th>Example of matching field values</th>
220 <td>the.*x.*files</td>
221 <td>"The X files", "The X-Files: the making of"</td>
225 <td>"Star Trek Voyager", "Star Trek: The next generation"</td>
230 It is possible that different programs cannot be recorded
231 since they overlap. To deal with such conflicts, it is possible
232 to specify a priority using the <code>priority</code> element.
233 Higher values of the priority value mean a higher priority.
234 If two programs have the same priority, then it is (more or less)
235 unspecified which of the two will be recorded, but it will at least
236 record one program. If no priority is specified, then the
241 Since it is not always desirable to try to record every
242 program that matches the criteria, it is also possible to
243 generate notifications for interesting programs only without
244 recording them. This is done by specifying the
245 <code>action</code> alement with the content <code>notify</code>.
246 By default, the <code>action</code> is <code>record</code>.
247 To make the mail reports more readable it is possible to
248 also assign a category to a program for grouping interesting
249 programs. This can be done using the <code>category</code>
250 element. Note that if the <code>action</code> is
251 <code>notify</code>. then the <code>priority</code> element
258 <title>Notification configuration</title>
260 Edit the configuration file <code>org.wamblee.crawler.properties</code>.
261 The properties file is self-explanatory.
270 <title>Installing and running the crawler</title>
273 <title>Standalone application</title>
275 In the binary distribution, execute the
276 <code>run</code> script for your operating system
277 (<code>run.bat</code> for windows, and
278 <code>run.sh</code> for unix).
283 <title>Web application</title>
285 After deploying the web application, navigate to the
286 application in your browser (e.g.
287 <code>http://localhost:8080/wamblee-crawler-kissweb</code>).
288 The screen should show an overview of the last time it ran (if
289 it ran before) as well as a button to run the crawler immediately.
290 Also, the result of the last run can be viewed.
291 The crawler will run automatically every morning at 5 AM local time,
292 and will retry at 1 hour intervals in case of failure to retrieve
293 programme information.
298 <title>Source distribution</title>
300 With the source code, build everything with
301 <code>ant dist-lite</code>, then locate the binary
302 distribution in <code>lib/wamblee/crawler/kiss/kiss-crawler-bin.zip</code>.
303 Then proceed as for the binary distribution.
308 <title>General usage</title>
310 When the crawler runs, it
311 retrieves the programs for tomorrow. As a result, it is advisable
312 to run the program at an early point of the day as a scheduled
313 task (e.g. cron on unix). For the web application this is
314 preconfigured at 5AM.
317 If you deploy the web application today, it will run automatically
318 on the next (!) day. This even holds if you deploy the application
319 before the normal scheduled time.
323 Modifying the program to allow it to investigate tomorrow's
324 programs instead is easy as well but not yet implemented.

332 <title>Examples</title>
335 The best example is in the distribution itself. It is my personal
336 <code>programs.xml</code> file.
